LS2 408 Nitrous setup
Hey Guys,
I have an 05 Ls2 corvette with an all forged 408, TFS 225's, LSXR intake, 11:1 CR, Bullet cam (246 @.620/ 255@.620) 1.8 roller rockers(according to the reciepts that came with the car when i bought it) and so on.
I have a NX 92 Plate and I was wanting some feedback on this setup on nitrous. I have the Maximizer 4 progressive controller so i was thinking about doing a 150shot on pump gas and a seperate racegas tune for 250shot nitrous with the progressive controller ramping it in for safety.
something like this:
Race gas setup:
RPM- Nitrous
3500 -150
4000 -175
4500 -200
5000 -225
5500+ -250
Any thoughts?

my initial thought and response is if you really want to go bigger than a 150-175 do a direct kit. you sometimes get pooling issues with a plate on an lsx with a big shot. not saying you can't or that people don't just saying a direct setup would be safer IMO to reach your goals. Honestly it all depends on your setup. For me a street driven car on the bottle i've decided to just do a dedicated fuel cell and put c16 on it for the nitrous. that way i can just fill my regular tank with 93. no worries about mixing octanes or separate tunes. and running race fuel full-time in it takes a lot of the "math" from the tune out of the question. the progressive will help with traction if its an issue for you right now.

Agree with the above poster. You'll need a standalone for the bigger hits to prevent fuel starvation at the injector. Anything over 175hp kit should be a direct port for the best distribution.

I did the seperate cell with C16 and direct port on my CTSV and I've been avioding adding that to the Corvette because I'm going to twin turbo the car sometime soon (probably around april time frame) Maybe I will keep it on the 150 and pump gas until then.
