200 dry with stock 98 injectors and stock fuel system?

I think it's probably more like a lean 150 dry shot.

On HackerJoe's car back in 1999 we ran a 2 stage wet/dry, with an inline T-Rex, and 114 unleaded race gas. Car picked up 19mph in the 1/4, I think that's okay. If I did that again I would do a 255lph intank pump + bigger injectors.

I run the mods in my sig and would only consider doing about 100-125 dry with my setup.

1320???? You have a car that makes 505hp and runs 10.30s??? And with a 200hp shot you can go from 12.30s to 10.30s?????? <img src="graemlins/gr_bs.gif" border="0" alt="[bullshit]" />

Yes I do......but I didn t say it was an F body...... its a vette and a lot lighter then an f body......2840lbs.

It also has a direct port fogger for a second stage......but its never actually needed....

Would you like pictures too? Its red with black interior, convo pros and et streets.

XSuROsISX, I have a problem with you telling people that you've done a 200 dry shot on a stock fuel system when you have not. If someone actually does inject 200 HP worth of N2O into their LS1 with a stock fuel system (which again, YOU HAVE NOT) then they run a very high chance of making a costly mistake based on your erroneous claims. That's not good, and it's just the kind of potentially costly misinformation that we want to keep off of LS1Tech.com.

I too have tried a 5177 kit with bigger 'noids and I'm here to tell you that you CAN NOT flow 200 HP through that kit even with bigger 'noids and the jets removed. PSJ is right, you *MIGHT* be able to flow 150 HP through this setup but let's not call it 200 and safe. Someone else might actually flow 200 HP of N2O with another setup and a stock fuel system...NOT good. <img src="gr_eek2.gif" border="0">

not to say i'd try it, but...

why can't you run that much power through it? i am seeing that the solenoid is too small to support that, so replacing that with a larger one is a start. is the main feed line to small to flow the amount of nitrous needed to make that power? just wondering why it can't be done.

I think (but don't know) that it's the two small lines going into the airlid. What I do know is that if you try it you'll see what I mean.

XSuROsISX

oh yea, I am lying....for your information, I have run a 200 dry shot, I had straight 4an line, 1 of them running into my airbox coming off the proshot noid, the tip of the nozzle was smaller than the 200 jet so it had to be drilled out. Thanks for your expert advise on saying it's impossible and can't be done, I ran this on a stock 98 fuel system and my motor is still running....thats one of the reasons I don't read your homepage Colonel...

I would do alot of research on ALL the boards and then make an intelligent decision based on what others experience and your comfort level. If you want to run 100 HP max then you'll be able to SAFELY do that. Once you decide to move up from there, you should have a diagnostics software package to monitor your engine, and a dyno to tune your car in concurrence with a MAFT. Don't pay attention to the guys bickering, they all good natured and passionate about the sport, sometimes we all get carried away.
Personally I'd go wet <img src="gr_grin.gif" border="0"> <img src="gr_grin.gif" border="0"> <img src="graemlins/camaro.gif" border="0" alt="[Chevrolet]" />

"I had straight 4an line, 1 of them running into my airbox coming off the proshot noid"

Ohhh, but I thought this was a 5177 kit with bigger noids? So now it changes since we all know that a 5177 kit can't flow 200 HP worth of N2O with just bigger noids. <img src="images/icons/rolleyes.gif" border="0">

I just LOVE these convieniently changing stories. You buddies with Juevos by chance?

Look, you dyno that sucker NA and then again on the bottle. Or at the very least let's see some trap speed comparisons NA and on the bottle. You get what should be a 200 HP gain and then I'll believe you. Until then we of the safety conscience mindset will just have to accept the simply fact that...28.6 lb injectors DO NOT flow that well!

I couldn't tell you how many folks have reported COMPLETELY maxing out their injectors around here and on the old LS1.com. I did it with a 125-135 shot (26.4 lb injectors on a 2000.) You honestly want me to believe that an extra 2.2 lbs of injector would have allowed me to run another 65-75 HP of nitrous?

One more thing. Saying that a dry 200 and a wet 150 are the same thing is just wrong. If they make the same power then the dry isn't 200, the wet isn't 150, or both. If they don't produce what you call 'em then call 'em what they really are.

Like I said before, this kind of misinformation is exactly what we're trying to avoid here at LS1Tech. We're trying to help folks run N2O SAFELY.

BTW, I never said you were lying. You put those words in my mouth (which I don't appreciate, btw.)

There is a big difference between lying and just not knowing what you're talking about. No offense intended. <img src="gr_stretch.gif" border="0">

I remember last year at an event someone ran a 175 dry on a stock 98 fuel system. He ran 150 first and then changed the pills. I do not remember which kit though. And no, i would never run anymore than a 150, even if people had done it, its not worth it to me.

I would keep the dry shot below 150 and also use wet as the main stage.. I was running a duel dry shot .093 first stage and a .063 second dry and made a few runs but had tons of problems and finally blew the motor out of the hole.. I made 400 RWHP on motor and 656 on the spray..That was through a #7 pump converter.. After all the problems I prefer BIG wet shots now or dry shots, 125 and under..

Thanks for all of your help <img src="gr_stretch.gif" border="0">

Matt98SS

you will more than likely max out the MAF on a 200 shot with the stock injectors so you can have jets for 1000 hp in there but it just wont work. the dry will limit you period cause of the MAF flow rates

I used a 150 dry set up for 2 years. I did lose a motor in that time, but is was due to a faulty oil pump!! <img src="gr_sad.gif" border="0">
