LT1 F1R Procharger wanting to up the power

[96famaro]

My setup
- splayed 4 bolt mains9:2:1 static compression
-forged 383 bottom end
-Trick Flow heads 23*degree LE ported 215cc runners, 2.08 IN. 1.60 EX. Double springs (155lb seat) 62cc combustion chambers
-LT1 intake LE ported
-Cam 224 in. 236 ex. @.50 574 in. 572 ex. 114LSA
-24x connection
-Pacesetter longtubes
-F1R procharger @ 14.8psi. (93 octane pump gas)
-31x12x4 cxr racing intercooler
- -8AN fuel feed. -6AN return
-lonnies double fuel pumps ( hobs switch)
- Siemens 80lb injectors
- snow performance straight methanol dual noozle
-Aeromotive 1:1 boost fuel regulator 54psi baseline

Alright that setup makes 700rwhp @5800 rpm 652rwtq @5200
Ok so this is a weekend car and will be running pump gas (93 octane). I'm looking to get more power out of it and was wondering what my injectors can support. The tuner said i was at 90% duty cycle. I was sure it would have supported more but not sure. Do you think it would do ok with 20 psi? Can i add another fuel pump maybe? And if i add 150 shot of nitrous is it definitely going to need more injector? Some input would be great on this. I know LT1s have made bigger power but ive only seen them with turbo setups. Let me know your thoughts. I'm i pretty much maxed out on my cam or something else that might be holding me back? What will it take to make around 1000rwhp given i change out whats nesessary ? Will the blower even be able to do it? Lots of questions but I'm ready to up it up!

[blackbirdws6]

I don't see you hitting 1000rwhp with that cam. Maybe if you crank up the boost and then add the 150 nitrous shot on top of it that will get you close.

With more boost, you will be creating more heat, less efficiency, etc so for each lb past that sweet spot, it won't have the same power increase. I think I have the same intercooler as you and that may be a limiting factor as well.

Just curious but are you just looking to hit 1000rwhp as a fun number or have a plan to use it all?

[popo8]

Wondering the same thing... at 602 rwhp... mine is a handful... i gotta say that is alot for a street car.

I think if you upped the boost you may have to increase your valve spring pressure. You'd have to talk to lloyd about what springs you have and what they are rated at with the valve open.

[Injuneer]

What trans are you running? Makes a difference, since we have to estimate flywheel HP to evaluate the injectors. What base fuel pressure are you running? What type of nitrous shot - wet (affects fuel pump, not injectors) or dry (affects fuel pump and injectors)?

It has great street manners and drives just like a stock car would. I'll be happy if i can get maybe right at 800rwhp without nitrous.bumping boost up, you think it will have detonation problems aroind 20psi? I'm looking for more power cause my Vipers have almost that with very little and I dont want to be left behind. And this is a shop car also so really just for fun.

OWNER/ADMIN well ive got the blower and figured why keep it held back when i know it can do more.


I think if you upped the boost you may have to increase your valve spring pressure. You'd have to talk to lloyd about what springs you have and what they are rated at with the valve open. cant remember exact specs but 155lbs seat and 400lbs i believe open.

What type of nitrous shot - wet (affects fuel pump, not injectors) or dry (affects fuel pump and injectors)? good points i forgot to mention. 54 baseline psi, and definitely i want a wet shot 125 to 175 shot but really thinking more 150. its a T56.

[96famaro]

Another question is if i do spray will i have to retard timing making it loose a lot of power up until i spray? Or can the timing stay where it is?

Adding boost and reducing timing should work fine. You have a meth kit so you might as well take advantage of it If you aren't already. Your build is similar to mine and I'm running 17lbs or so making nearly 800rwhp.

[Injuneer]

With the T56/12-bolt losses I actually measured with my setup (less than 12.5% at the 800 FWHP level), and not knowing the type of rear (9-inch eats up 3% more power than the 12-bolt, S60 consumes less than the 12-bolt), would put you at ~800-825 FWHP, and shooting for 1,125-1,175 FWHP. I've personally seen a 383ci LT1 with only a Vortech S/C (no nitrous) make 1,125 FWHP. ran 9.05 @ 156MPH at almost 4,000# race weight. After he decided he needed more power, he went to an aftermarket Gen 1 block. When the LT1 was sold and torn down, it was still found to be in excellent condition, indicating the block could actually handle that kind of power. Interesting fact was the block was a Corvette 4-bolt main, with STRAIGHT, not splayed end bolts (obviously, the bolts and caps were upgraded). Was not using meth. Had a water/air intercooler. Believe he was right at 9.0:1 SCR, but was running C16.

If your injectors are already at 90% DC, something doesn't seem right. If the injectors are rated at 80 #/HR (at what pressure? - typically 43.5 PSI), starting with a base pressure of 54 PSI, and assuming 10 PSI boost, they should flow ~96 #/HR at 64 PSI. Something doesn't add up.

Hopefully the forged bottom end is very high quality parts.

Here's the dyno graph. Sorry for poor quality.
I just remembered that not long after getting the car back an o2 sensor was going bad. Changed both sensors and ran great and still does today. Another thing was when I drove the car home it felt very slow on moderate acceleration. I didn't think much of it cause I didn't want to go (W.O.T.) until I got home and checked to make sure everything looked good. Well I got home pooped the hood everything looked alright until I moved around the left side blower piping, yup sure enough it had apparently popped off on the last dyno run they did. I got it put back together and once again major power increase!!
So I have a few theories
1) could it have been that maybe the o2's were causing tuning misfires?
2) maybe the piping wasn't holding together?
3) could it be that perhaps the fuel tank needed to ventilate more For the injectors?

It seems that my power curve starts to drop pretty good after 6,000 rpm. I figured it should have been making peak power around 6,200 rpm and not drop like that. I'm ready to do this so really appreciate any help so I'm not spending time or any money on something that won't work. Thanks

[blackbirdws6]

It's peaking around where I would expect for that cam. The curve is smooth so doesn't look like any misfire issues. A boost leak is possible but it would be small as having a pipe come off would not result in that kind of power.

Honestly the power curve looks nice. Increasing boost should move the midrange up significantly but you may not pick up the same amount up top. The comment regarding spring seat pressure is going to be important if you are increasing boost.

I saw a soft amount of valve float when I went from 15 to around 19lbs. Mid range picked up big time since it saw more boost earlier but went soft up top with nearly the same peak numbers.

New valve springs, same cam and minor valvetrain changes netted me another 70 or so at the tire.

Cool man. I told llyod to put me the best springs he had. What kind of spring did you end up with after?

I'm using Manley Nextek springs. I have to look up the seat pressure they were setup for though. Original springs were Patriot Gold Extreme pieces.

[96famaro]

Awesome sir. Thanks

[96famaro]

I figured I give an update of my new setup.
- E85
-OBX longtube headers. 3.5 collectors, stepped 13/4 to 1 7/8 primaries.
- bumped compression up to 9:8:1 (wanted to go higher but I'll run this.)
-got a 4 inch blower pulley. Looking for 20 psi or little over that.
-redesigning my loonies double walbro in tank feed setup.
- walbro 255 lph pump and walbro 465lph pump in tank pumps.
-3 inch true dual exhaust, X pipe under axle with C6 Corvette Corsa sport mufflers
-Manley Nextek valve springs with retainers and locks.
- dual methanol nozzles.
-Diamond .040 over bkower pistons
- Bosch 160lb injectors high impedance.

I took the heads to Lloyd and we found out that the old springs were in fact having valve float issues. I talked with my tuner and he said gains of 100 rwhp was possible just from switching 93 to E85. I'm going to shoot low but I think it will put down 850 rwhp this time around. What do yall think?

[myltwon]

That's awesome!

[blackbirdws6]

Willing to share how you are modding the Lonnies twin pumps to the bigger units? Did you already do fuel lines? Switching to E85 and pushing more timing should net some nice gains. What were you putting down before? Maybe you already posted that info.

Keep us posted.

Sounds like fun. Couldnt inagine doubling my boost...

Keep us posted. I don't mind it one bit. I already installed my fuel tank back in the car with the way Lonnie left it, so I have to get it back out again when I'm ready to do it. This was just one of those last minute decision. I feel that it has flow restriction on the T- fitting. I'll share how i go about doing it my way. Real reason this idea came up is when i ran across one of Squash Performance dual pumps for my CTSV setup and got me thinking.... I modified my fuel rails. Added a larger diameter feed tube and added an additional bridge tube. -8An feed line, -6AN return. was putting down 700rwhp.

OWNER/ADMIN yea i figured id step it up. I don't want to be left behind by the new gen LT1orLT4 which seem to make ridiculous power with little proper tweaking.

[96famaro]

Forgot to mention that I believe my electrical might have not been up to par as well. It might have been ok but I like to know that it wasn't just borderline. I ran a 2/0 gauge power cable from rear to front of car and two 2guage ground wires to rear chassis and 2 gauge ground cable, engine block to chassis. And a 2guage alternator power cable to front positive distribution point. I also upgraded the alternator to a Cadillac Escalade 145amp. I also moved the Racetronix dual fuel pump wiring to where the positive connectors are connected straight to the alternator output rather than putting it at the positive distribution point.

Is that Aeromotive FPR rated for E85? Over the years, the Aeromotive LT1 unit has had trouble with regular gasoline, and they claimed it was due to "changes in the composition of pump gas". They still show up with problems, even after all these years. When we paralleled the rails on my setup, we went to a Weldon stand-alone FPR. Feed fuel into the back of both rails, take the single return off a -6AN fitting welded to the stock cross-over pipe, line back to the Weldon FPR mounted under the cowl.

I wasn't aware of that regulator having issues, thanks for The heads up. Will it have problems running E85 for sure or is it just random if it gives? I bought it about 4 or 5 years ago with no problems so far but hate for it to cause a fire for something that can be avoided.
Would it be a benifical running a parallel setup?

Possible first start later today. Just a mug shot but thought I'd share my progress so far. I'm curious to see how much better the charging system and whole electrical system do this time around. 145 amp Cadillac alternator as opposed to the 105 amp ls1. It fit in quite nicely.

Looking really good. What rings did you go with? Any additional plans to mess with the engine cosmetically?

[The SRZ]

Nice bay! I really need to do this while mine is out. Is that a standard ATI bracket I see holding your F1R?! And why not just run a 200 amp alt? I've been running one for the better part of 10yrs with no problem. Tuff Stuff performance makes them.

[383z]

I agree. Nice engine bay. You had everything painted and done correctly.

Total Seal rings. I got them through Diamond. I still have to prep and paint the blower piping, paint the LT1 engine covers, undecided if I want to paint the valve covers, don't like how aluminum don't stay looking clean for long. I have a gen V Camaro engine cover that I can switch on and off if I like so gotta paint that too, going to make a pcm cover, and then add some LED lighting to engine bay so it turns on when I open the hood. Will serve as two purpose a work lighting and just to be cool.

I heard of supposedly lots of bad experience about aftermarket but I might try one out in the future.3656436565365663656736568
I'm going to redo this top bracket with some thicker plate steel. The blower has almost no flex compared to how Procharger stock bracket is. It made a world of a difference from how it is originally.

I agree. Nice engine bay. You had everything painted and done correctly. thanks

[96famaro]

Still don't have it where I'm happy with it just yet, but figured I'd share an engine shot of work in progress. I'm not ready to show off the rest of the bird quite yet for final unveiling. But very soon now. No more stupid blower piping blowing off anymore, I hated that. I Built tabs so I can bolt on the pipe in place. I think I'm more thrilled about that than the rest if everything else lol. I keep finding new stuff here and there that I want so it's taking me longer than I had wanted to take on this build, but oh well. I'll probably order me 09+ CTSV front/rear brake setup here shortly and ditch my Zo6 brakes for another build.

Setting out to dry right now. I can put it on later tonight. Engine cover should look 20x better once I'm done with it, I've got some cool ideas for it.I like that it gives a modern LT1 look. I'm just not a fan of seeing a bunch of coils and wires all over the place.

Excellent. I agree it's tough to make an 8 coil setup look clean unless you actually relocate them.

Back to updates. I ended up getting a powermaster (AD244) 220 amp alternator. The O'reilly 140 amp would drop voltage every 10 seconds and then back to normal and would just continue to do that so I wasn't going to deal with it. This new one seems to be doing quite well so far with plenty of voltage.

I was originally going to be using these fittings with the metal housing but changed my mind on it and not to mention was dealing with height issues as well.
36993

Picked up this 3 way manifold fitting along with the 3/8 barb fittings.
36994

If you look closely you can see a somewhat restriction of flow. So I got my Dremel and opened up all three ports.
36995

I couldn't find flexible fuel hose that was the 3/8 that I needed so I went ahead and used nylon hose. I found a place on ebay but was like $50 bucks for 1ft I think. Quite pricey for something simple.
36996

I used a brake flare tool to grab the line and then get the pump pushed in using a wooden block and a hammer. No heat or boiling water and gets the job done super quick and very air tight sealed.

Bought a fuel sender unit on ebay, took it apart and used just the sender unit. (0-90ohm)

OK if you've been reading this far this is quite important concerning my situation. Sorry about the clarity but this is the pinout for the fuel pump that goes to the yellow bulkhead inside the tank. My issue is my pump stopped working out of knowhere. It took me awhile to track it down but come to find out the connector and plastic housing had gotten so hot it started melting the connector. Definitely do not want it failing during a wot pull or ever happening for that matter.
37011

37009
I got the problem repaired but this time what I did is I used the factory bulkhead and tapped into Both fuel pumps wiring in hopes that it will help give more current flow to the pumps. It can't hurt. Honestly while testing the pumps outside they sounded stronger than ever. If this isn't enough fuel system then I'm leaving it alone lol.

37012
Here you can see the whole reason I rethought my pump system. I feel it should flow much better now by far.

[96famaro]

The 21st of this month I'm taking it in to get it tuned with the E-85. I bought 160lb FIC injectors so it should be plenty to keep her feed. I am concerned about my clutch though. Never even crossed my mind until my tuner mentioned it to me. What is recommended. SNL tune my car so apprantly they have a clutch now for us old LT junkies?? Or the new LT?? Last time I asked they didn't have anything but found a link that claims it is.

[blackbirdws6]

Good work correcting the fuel pump issue. That would not have been fun.

As for the clutch, I'm running the McLeod street twin which is supposed to hold 1300 or 1500hp (can't remember and assuming crank hp). It's a great clutch with very good driveability.

[shownomercy]

That wiring is slightly scary IMO.

I'm not feeling very confident on my clutch. I have a feeling it's going to slip during tuning.


That wiring is slightly scary IMO.it's just simple power and ground in a tight area.

I bought one of these units so I can see some, on the go data on my android stereo. I haven't had a chance to try it fully, but so far it's pretty cool unit.

I haven't really dug into it but does anyone have experience with utilizing e85 composition sensor on LS pcm?

Since I'm using twin 465lph walbros, I had no choice but to cut and remove the bucket part of it. There was just no way to get it to work. Shoot, it barely fit to get inside the tank as is. I'm still brainstorming on what can be done to put a baffle in it. Aeromotive sells a kit that I may be trying out so we'll see how that goes. But for now it stays as is.
34 hours and then tune time.

Those pumps draw 14 amps at full load, seems very risky IMO to risk your fuel supply on little plastic rigs.

Car put down 770 horse and 722 torque at 15psi. 100 degree temp and high humidity. Entire powerband picked up. I knew something was wrong because boost was exactly the same from the 4.5 to the 4 inch pulley. Boost graph showed it just flatlined in the upper rpms and power followed right with it and I knew that couldn't be right. Checked belt seemed little loose but not too bad. Didn't show any signs of it slipping.
It was a long day and wrapped things up and went home so I can figure things out. Surely enough did a boost leak test and, major air leaks. Coupler around throttle body was gushing out that was the worst area.

Here's a vid of the boost test. When I turned up to around 18 psi it felt like a fan breeze.

This what I found leaking out.
-blower volute
-coupler on blower
-pipe where it was welded
-coupler on throttle body
-blade shaft on throttle body
-tps sensor area
-fuel rail bolts

How much boost will you be running? I have a video that sounds exactly like yours. Shit made me laugh when I heard it.

Nice numbers. Post the graph I'm curious to see your torque line.

20~23 psi range. Haha, yea it was loud. Once I put more psi to it I had to put some ear plugs. The oval shape is just horrible to make a good seal. I put sealant and stopped it completely.

I'll try and post it up. I'm not really impressed on the power. I guess cause it's running E85 and the other tweaks I made I figured a decent gain. I think once it builds the extra boost it should be closer to what I had in mind, but time will tell once I retune it.

Thanks. It's is OBX long tubes, 3 inch duals with X-pipe, out to Zo6 Corsa sport mufflers with 4 inch tips. I'll be changing out mufflers to the Corsa Xtremes soon. I love it, one of the best things I like about the car. Quiet as can be inside the car but really loud outside. Can't wait to hear the Xtremes roar.


Very nice car! Very clean! Nicely done!!

I put sealant around the volute. It had leakage all around. Sealed off 100% now.
37091
Sealant around bottom crossover. Didn't have leaks that I was aware of but didn't want any.

Took apart throttle blade shaft and drilled another hole up top for greater spring load for the throttle to snap back and put sealant at the ends. Tps sensor area had major leaks.

[blackbirdws6]

Solid numbers and the car sounds great. Hopefully sealing things up will net you the additional gains you are looking for. It's tough to button these things up entirely but you have enough leakage to make the effort worth doing.

When is the retune?

Thanks. I'm curious to see how the added boost is going to respond with E85. It was 100 degrees and humidity was quite high. Temp have started dropin some so It did ok for that day with issues. I got everything finished and fixed as far as leaks go so I'll be finding out just how much more psi it will do. I don't have a set date when I'm going back for retuning but it won't be long now. How's the T/A holding up?

Yup. I took it apart and put sealant on the throttle linkage end and made an aluminum spacer for the tps sensor side and added sealant. No More leaks.

Very nice. TA is still running well. I've been taking it out about once a week if the weather is good. My annual track rental is coming up in November so I've finally pulled the trigger on a set of 28" slicks. Hopefully the little tweaks will net better times.

[96famaro]

Well as much as I really liked the cam I had in, I just wanted something that had a lot more chop to it. So I called Lloyd and got me a custom grind cam on the way. I also had some other issues that I'll show a picture of for anyone who is running the 24x connection kit, just to give the heads up.
37116
This cam is a lot more nicer machine finish than the comp cam that was in it. The lobe surface areas are wider and the bearing surface area are wider as well aND overall grinding finish looks better.
37117

37119
Here was my problem. The cam reluctor was grinding the inside cam sensor plate and I was getting a check engine light because metal debris. It was also hard to start at times and I was confused what to look for. But once seeing all that junk, I know that has to be my problem. So I'm going to trim the inside just enough so it won't do this again or later on for that matter.

Awesome! I hope I can get this finished so I can actually put some decent drive time on this thing and start to enjoy it a little. I want to get it setup with slicks and for drag at some point but you know how it goes, "it never ends". You Gotta let us know how new setup does.

[blackbirdws6]

I recall I had a similar issue on mine but it was minimal. Guess I got lucky.

Sounds like you are going for the gold with the cam. I have a Lunati in mine now and so far so good. The prior cam was a bullet grind.

I will let everyone know how the car does at the track. I normally race it at the end of the season since the weather is good and if it breaks...I have all winter to mess with it. Fingers crossed.

[96famaro]

Got the car running few nights ago. Car sounds much better!! I ran into a big issue that was my fault. The ARP crankshaft bolt snapped off while trying to remove it. Took me three days but I got it out with no damage to crank. It was a fight to get out. Anyways got it fired up and had camshaft reading problems real bad (code po342) wouldn't start when hot and backfire a lot. Well read cam data feedback and noticed signals where at zero and so I started moving my harness around and then noticed cam signal started to read on and off. Yup, sure enough went to unplug the cam sensor connector next to the valve cover and the pin just broke apart. Fixed it and runs great now. 17 year old harness so now I'm just thinking of just getting a whole new engine harness to start fresh with. All that's left is few adjustments, and do a final boost leak test, and retuning should be eight around the corner.

Here's the crank bolt I got out, what's left of it at least. I drilled straight through it little at a time. If I had used reverse taps, it would have came out faster.
37148
This is what I'm working on at the moment. I bent one of the throttle blades and after that I could not get it to come down to idle correctly once the blower pipe was hooked up, no matter what I tried. Long story short I screwed up the throttle blades but I had some new ones ordered this morning. I was using sealant to stop my boost leaks and it did work. it just was not good because I was having problems now with throttle not coming back to idle and it was a process just to get the pipe disconnected to service it.

So upon all of that going on I'm just going to build a plate and weld it and add a gasket so I can take the piping on and off how ever many times I need to and not worry about boost leaks. The oval shape is just a nightmare to get anysort of good seal out of it especially once the boost started to build up.
37149

[blackbirdws6]

Glad you got that bolt out. If it was me, I would have been throwing quite the hissy fit and likely ruined my crank.

As for the TB, I ditched the Holley as it gave me similar problems. It would not close all the way so I had to kick the throttle so it would slam shut. Switched to the AS&M and zero issues with a much better pedal feel.

Yea I definitely was relieved once I got it out.

I think I got the whole throttle body sticking situation sorted out by can't say 100% for sure until I try it all. If all else I might look into that one you mentioned but I have confidence of it working this time around.

I had the same issue but much worse. And the F1 being so loud I couldn't hear it screeching. I had catastrophic failure, the cam walked in the journal and snapped in half because of it. I wonder why EFI hasn't caught this as it seems to be an issue...for some anyways. Glad you found the culprit!

First off, nice build. Reminding me how time consuming its going to be putting mine back together, especially with a 3 year old around now.

Secondly, one more reason im convinced I'll be tying Torqhead 24x. Lots of good info and motivation/ideas for us boosted addicts.

Thirdly, I'm a little concerned about that fuel pump setup myself. I have used epoxy around fuel before and it didn't end well. Fuel seems to eventually soften the epoxy. I'd be concerned the pass through fitting may come off, and causing fuel leakage with a full tank, and maybe worse case, catch fire.

I'd like to try something similar, so let us know how that works out please, but do keep an eye on it!! I don't think I'll need the amount you require as I'm aiming for the range you were supplying with dual 255's

Still had some issues. This was @18psi. Who knows what it would pick up if I had made the 23 pounds of boost that I was wanting to give it. I still could have climbed little higher on the rpm band but it was peaking out on that pull. The clutch was starting to slip and I called it good there for now. I really do think it's got another 100+rwhp left in it.
And ambient temps that day were in the 80 and lower 90 degrees. The thing is now moving some air.

The power curve is smooth. Peak numbers aren't the full story. @3,000 rpm it's putting down about 600rwtq and about 380rwhp. Graph looks like roots blower curve. The car never feels weak at any given rpm and when rowing through the gears.

37527
Removing these two parts gained me 120 rwhp and I still left the blower hat on it. So if any gains to be had are unknown at this point.

37528
As we were talking and making adjustments. I'm gonna go ahead and grab one of these Procharger bell housings or get one from steve morris. There was a 427 C6 there that he gained 100 from removing filter and gained another 100 rwhp from switching over from a straight screen to one of the volute bells. That's a 200 rwhp gain.

Anyone have gotten their blower volute machined by Steve Morris. I may end up sending it out to him.

794 I think it was. I'm sure it would have gone past that with more tuning. The wild thing was we didn't touch the tune at all once I made that last pull. I pulled the plug on it cause that clutch is taking a beating at this point. It might have even graphed more power than what it showed cause the clutch was starting to give.

Well peak numbers aren't the full story. I've seen Turbo builds and the power just is not there like I'm seeing with the Procharger unit throughout the powerband. Still with A/C and everything else in the car. This is on a 12 rib as well. I built reinforcement brackets for the blower and made sure the pulleys were lined up true. I came up with an idea to help get better airflow to the blower. I haven't actually messed with it since but I'll be sending the blower out to get machined and the custom volute and then see what happens. I'm not sure when I'll do all of this though since at this point I'm already needing a clutch upgrade.

I'm already spinning the blower to max rated rpm yielding me at 18 pounds, but gonna wait on spinning it faster until I make some other changes first. So it seems that this combo is flowing the air pretty good. I would go for the 24 psi man!! Would love to see what it does! When will it be running?
