Evo 8 vs GT28 SR20

[Nyteryder]

why is the question being ignored? anyways would like to run that 240. what power is he making with that thing? has to be over 400.

I dont live on the cpu waiting for someone to post I check periodically, and me, charles, and Jason tried to run a 3way but have way through I had to shut down because of a misshift, but from where I was at him and charles seemed to be very close. My turbo is not capable of making that kind of power, besides I still have stock exhaust and intake manifold, cams and turbo extension. The gt2871 .64 will make about 360whp With the mods listed above.

What do you drive and what kind of power.

did you up the boost? my car was accidentally hitting 25psi due to a boost controller malfunction yesterday and although i didn't stay in it after seeing the boost gauge the thing was taking off like a rocket. i need bigger injectors .

I am running 18-19psi, an what I meant was when I upgrade my mannys and cams and turbo elbow I should be at 360whp. What injectors are you running.

SARD 550cc side feeds. according to the power FC i maxed them well before 25psi was reached so i'm just happy i didn't pop the motor. the powerFC may be reading funny though, because marshall's car made 396whp on 50lb topfeeds (~550cc) and never seemed to max them out. i'm not sure what base pressure he was running though with the JWT ecu that was in the car.

if I recall correctly enjuku was one of the first to reach the 400whp mark on 550/50lb injectors with the red hatch s13. As Erin stated I had a JWT ECU and also had a MAFS controller. This allowed us to adjust the voltage to the MAFS giving a finer tuning line for the a/f curve. I still have the graphs- although I think the 396 is on a floppy still- but some show the a/f curve and it was dead on the money. I think we could have hit 425rwhp with those injectors but would have been maxed out at that point. I used a stock 300ZTT fuel pump, 300ZTT fuel filter, JWT fuel reg, and stock fuel lines with a JWT fuel rail.

If I were to take a wild guess as it was years ago, but I think my base fuel pressure was @42 with no vac.

wild guess but sounds about right.....
