I have no idea where the graphs went to of the full pulls, but it definitely revved out further than 6500, so don't worry it didn't stop there! I probably just forgot to save them before starting another folder..



So this 14psi was this 28.5psia? I am guessing you are tuning with a map sensor? I am guessing 375whp on 14psi. That is pretty good for that setup. I've never been on a dynamics dyno, but I'd be interested to see what my car would put down on one.

He said he's runing a z32maf. And I'm sure it made more power. This graph gets cut off at 6500rpm

I wanted to go for 30 psi...but the injectors didn't agree with that plan


None of the "available" correction factors work on turbo engines, since it varies based on the map of the charger. Turbos function based on pressure ratio.

First, my brother's SR20DE-T 91 SE-R
Stock motor
Stock DET manifold with adapter plate to T3
Hahn racecraft 20G turbo
550cc Injectors
Stock MAF
12psi
Stock code tuned with Nismotronic
(Getting Z32 MAF and TunerCode soon!)



Stock SR20DET
Equal Length Turbo Manifold
3076R
14psi
780cc injectors
Z32 maf
TunerCode tuned via Nismotronic

2.5" dp to 3" exhaust with resonator only



12psi on the 1st two runs and 14psi on the last and what a difference 2psi can do!!!


that's a bit low for 14psi no? I made the same whp but a litle less wtq at
6psi on a t25.

He probably would have made more but by the looks of his boost graph his turbo is not holding boost or his boost controller isnt working right . I would change those injectors too 370cc is alittle low for 14 psi.

^ you're right I missed that he's falling after 4500

I feel like I'm missing about 10 hp but if you look at the 12 psi run the turbo doesn't spike or drop off after 4500, I realized this once I turned the boost back down to 12psi that anymore boost is just stress on the little snail.

I know the reason I'm missing a few horses and that's because I have the DE intake mani swapped onto the DET motor I did it during the swap for easier installation cause everything was already on the DE mani. This winter I will be either swapping the DET mani back on and all the other parts or just getting the DE mani port matched and adding thermoblock spacers...
