Going from 200 dry to 400 dry discussion?

[1sickta]

I'm currently run 2 NX noids jetted for a 100 each. I'm going up them to 200 each (if it will flow that threw a -4 line. Each noid has its own bottle and feed line. Using 60lbs inj to fuel it and adding another 255 Walbro and feeding it to the test port drilled out to 1/4 and using 3/8 line from pump to rail.

I'm open to discussion so feel free to chime in with any thoughts.

whats the total amount of power you are expecting?

[1sickta]

Current setup is 600 RWHP. Somewhere around 750-775

[1sickta]

Engine specs 383 eagle h beams and crank. Srp pistons. 12.2/1 stock intake.

first concern is having enough injector to supply the fuel volume you will need, I am not sure a 60# is going to be enough

second you talk of having 2 solenoids with independent bottles and lines but what are you using to inject that amount of nitrous. I hope you aren't wanting to hit a 400 shot on a dual nozzle setup.

Please give me as much detail on the engine and nitrous system as you can. Feel free to take this to PM if you want.

I will be tuning it in on a dyno, with Bluecat(Phillip Smith) watching the AFR and duty cycle on the injectors.

I am using these nozzles

I must of lifted a little and caused the WOT switch to pulse. We seen it on the graph in the running software. Only happened on the pull I videoed.

I also have a mono blade TB I need to install.

That looks awesome with the clear lid!!!

I would advise against spraying a 400 shot on that setup, but to each their own....I am afraid distribution is going to be far from ideal

[1sickta]

I can't say I don't dissagree. What's your opinion on a max total on that setup? On the current 200 shot its performed flawless.

i figured on 200 dry you where risking it LOL why not switch to a wet setup? and youll be fine on 400 on 2 pins... i did it for like 3 years on my old setup on my Z28... motor was fine, i pulled it to put into another car. the LT1 intake seems to do a pretty good job of distributing with a pin setup. now, im not saying that this is better than direct port, but i had great success spraying on 2 pins.

[Chopstix]

200 is the most I suggest on the lt1 intake without a direct port due to distribution....do some folks do more, yes, do some folks replace pistons, yes...you decide.

[1sickta]

We went to the dry setup to be able to inject the fuel to each cyl without worrying about puddling or distribution of the fuel itself.

I will step it up a bit at a time to see how it pans out.

What gas are you running? you running a dedicated fuel cell? Your set up already runs good man, looking forward to see how it goes.

[1sickta]

All stock fuel system besides 60lb inj and a single walbro 255 on 93 pump gas.

Im upgrading to a dual intank setup before upping the shot. One pump will run all the time and the 2nd pump will turn on when the system is armed. Each pump will have its own feed line to the rails.

[1fstss]

stock LT1 line will supply enough fuel. i run dual 255's in my SS and have no problems running both pumps into 1 line...
