SCT + stock turbo + S2 = ?

[evo77]

I'll be resorting back to stock turbo shortly and I want to get some more feedback from those of you with this setup and possibly dyno #'s?

During my search I have found a few with roughly on average 240-260 hp and 300+ tq.

I'll have basic mods:

- stock turbo
- S2 no toys (injectors, sensors, wga)
- 3" turbo back
- bfmic
- 255 fuel pump

Stock everything else. Even the air box.


I'm mainly interested in seeing the torque curve. I'd like a tune that will give 300 or more tq starting at 2500-3000 rpm.

Don't see a wideband in your list... Would be a very easy tune. I'm about 2 hours west of you if you want some help, and I know a guy with a dyno about 20 mins from my house. He will charge you for the dyno time of course.

I could see 270ish whp and 330ish wtq Outta that setup considiering the SCT is tuned well. Im sure you got a wb right?

And we all know max tq is around 3000rpms on a stock turbo lol

I have a wideband.


I really like this dyno graph. Car is identical in mods to me except it has AGP wga and 3"o2 housing.

300 tq starts at roughly 2800 rpm.

With the exception of exhaust & pump , I have a similar setup . Due to a lack of datalogging yet , I am slowly street tuning my stage two base code .
It seems to me that there is a lot here , Im still working on fuel trims but about done , off the line power is WONDERFULL ! Pulls hard at low rpms , and im running the AGP RACE intercooler with almost no lag . PCM boost FTW !

Power Mods
SCT PRP (stage2 base code)
RC 650 injectors
ED hardpipes / HKS+stock BOV
AGP Race intercooler
3bar sensors & stage2 wastegate
innovate wideband & aeroforce gauge

Now I need cutout downpipe BAD !

I really loved the driveability of the S2 alone. Great low to mid torque. I was hoping to expand the high torque output but still retain the same curve.

I did the tuning you see in that graph. S2 WGA works better than the AGP, so no worries there. Looks like you have everything else you need to do it.

[evo77]

I would agree. I have seen many dynos where the torque curve shifts toward the mid to upper rpm band leaving the much sought after low end torque (2500-3000rpm) flat. *no pun intended*
