Video of a pass from last nights track run.

Hey fellas,
Take a look at this vid and tell me whatcha think. I was sorely tempted to change out the Stall from the current 3600, to a 4000…

Now she is working off of the mail tune, running heavy rich… so there's beaucoup room just in the tune, if i EVER find anyone that can dyno tune this car. But I am thinking that I may go to a higher stall… your thoughts?

It's up now…

Here's another vid of an earlier run…

Beyond not having slicks which is preventing me from being able to pre-load and, the tune leaving her heavy on the rich side, what do you guys think is holding her back the most? Heads? Under rated stall?

Could use some feed back.

Finally got a few free minutes to check out the videos (Can't watch anything youtube on the Government work computers).

Tune, tune, tune. We pulled a full second off mine (1/4 mile) with just changing the shift points and making sure the fuel cutoff and on was correct. Then, I was real rich too and after leaning in down at WOT, shaved another 4/10's easy. All that was with me having wheel hop/axle wrap issues off the line and cutting 1.75-1-80's.

How heavy are your front wheel/tires?
Do you have the ALDL cable to datalog?
The 5.13s might hurt you too, making it harder to put the power to the ground off the line and limiting topend.

[OVA1]

Oh thanks JC.

The Wheels are centerline, aluminum and they're fairly light. BUT, the tires are 275/40/17s… So there is some fairly significant weight to be shaved off of that, if you're talking about skinnies. I'll look around and see if there's a set to be had for the drags. I've also got a set of 15" salad shooters which are quite light… so I could mount up a set of nylon tires there to go with the pending slicks out back.

The PCM I have is the 96 OBD2. For whatever reason, I'm told that I can't log from that PCM.

Before I ran into the kid with the 5th Gen I walked, who turned me on to his tuner… who assured me that he could tune me car NO PROBLEM, that he had a guy, blah blah blah… only to tell me after me tranny took forever to get here, that his tuner was in the Middle east tuning for Abdul…. and it was gonna be a while. I was talking to Moe Bailey about installing an OBD1, which he could use to set up a tune, then I could log it and he could make adjustments to his base program.

Like a DUMBASS I called Moe off because I was going to get a dyno-tune from this east cost shop…

So now I'm back to square one on the tune and it is making me crazy! It shouldn't be this freakin' hard… Yet, it is.

With regard to the 5.13s, I hear ya… BUT, they're awesome on the street. And I'm hooked… Once ya run these things, ya really come to love 'em.

Now I've HEARD that a tuner can program the tranny to roll from 2nd gear when ya manually put the tranny in second. As it stand right now it doesn't do that. Put it in 2nd and it rolls through first and sits in second until ya upshift. But I am thinking that IF I launch from second, that would be a game changer.
The other thing is the possibility that I purchase 28" slicks. Not positive that wheel wells will allow it, but if it doesm I think that would effective gear down the 5/13s to something life a 4.5x or 4.6x…

But I gotta believe that there is a MINIMUM of a half second to be had in a quality tune. The car just feel FAT… it's got significantly more torque than did the old 350 setup, but it doesn't spin up as fast and it just doesn't feel as sharp as I believe it has in terms of potential.

I am running OBD-I so I am not sure on the able to log or not for OBD-II.

Shocks old and worn? adjustable? Factory rubber body mounts? subframe connectors?

It seems like a TON of people run the 3600 stall and love it. There are others like Joelster running over 4k right now, IIRC. He is at 414 cid though.

What rear tires are you running?

Gotcha… I am going to call the east coast guy tomorrow and see if he has a projected time that he can tune her. If he doesn't I'm going to just commit to Moe, unless someone else knows of a shop that can dyno tune the current setup, that is within a few hours of the house.

Shocks old and worn? adjustable?

KYBs brand new… stock springs. Presently have them at 50% of their scale. No Idea how to even approach adjusting them.

Factory rubber body mounts?

It's a unibody…

subframe connectors?

Have a brand new BMR SFC in the shop, as well as a brand new BMR Adjustable Torque Arm… they call it the "Track Pack", if memory serves. From what I understand, the idea is to transfer the torque moment farther back to the rear. It is supposed to really help get the load to the rear tires… which SHOULD bring the 5.13s into a force multiplying asset, out of the whole. Of course that assumes Slicks…

Yeah, I gotta say, for the old set up, it was perfect… Most guys, including the techs at Comp Cams, said it was too big, pushing too far into the meat of the torque curve. What I found was that it provided instant access TO THE MEAT of the torque curve and that gal hauled the mail son… let me tell ya.

That's what I was wanting a Dyno-tune, to get a better idea of where the meat is. On the video it sounded like it had a slight bog when she shifted into third. Nothing horrible, but it just labored there for an tick or two. So the idea was, if I increase the Stall, it sets that shift up into better torque values… thus less bog.

What rear tires are you running?

In that video, I was running he street radials up front and a brand new set of Nitto 555Rs… I literally drove from the tire shop to the track. They hooked a FAR SITE better than the street radials, but no where NEAR as well as the old Mickey Thompson ET streets, which were a nylon tire… which from time to time, given the radials up front did induce a scary wobble… but the Mickeys flat hooked. They stuck a 1.48 60 one great and glorious night. But that was also in the Vig 3200 which hit like a BOMB. But it also gave way too much, up top. The Yank, she doesn't hit as hard as the did the Vig, but she hold up MUCH better up top. If memory serves we picked up 3-4 Mph on the big end.

What is the weight of your car ? I think 513's is to much gear and your shifting out of your power band to early. What rpm are you going through the traps at ? I think your car should definitely have a 28in tire with those gears and a 4000 + stall. Oh I should ask 1/8 mile or 1/4 car I could see having more gear for a 1/8th mile track.


My car is a 383ci has 4.30 gears 28in tires and around a 4200 stall and works pretty well.
