LOL. that's what i tell myself, anyway. haha. honestly, it's the funnest 390 i've ever had. i <3 this turbo.

 

390 is fun. I made that on corn, with your old turbo. And 320 on 91

 

Sounds about right. On an 8? Hey, you're in Fresno, right?

 

On an 8 with stock cams. And yes I'm in Fresno, actually going to be running SCCA this Sunday. See how she goes.

 

You're the guy that bought my IX turbo? Shoot me your number. I lost yours so never was able to get ahold of you for our meets, etc. I'll be out as well. Hoping to have my girl driving this time.

 

Here's my results on CA 91 octane

2003 Evo 8
300hp / 283tq (Mustang Dyno)
Max Psi: 22.1

Mods:
Evo 9 turbo
Tanabe DP
RRE rally cat
HKS carbon Ti exhaust
GM boost solenoid
JDM MR BOV
HKS cams 272's
HKS cam gears
Stock airbox with k&n drop in
AMS LICP
Walbro 255lph fuel pump
RC 750 injectors

My goal is to have at least 350whp on a mustang dyno. Any ideas on what else I can upgrade to achieve my goal?

TIA!

 

from what you've got so far, e85 will do the trick. but you will need bigger injectors. maybe a bigger IC just to ensure no heat soak.

 

A more aggressive cam like some S2 cams will definitely help.. hks 272 are on the mild side in comparison to others on the market....

 

On pump, you will need a larger turbo.

I did 390 on a MAP ef2.5 and similar mods (Evo IX).

 

I appreciate all the input fellas!

 

I am having spikes to 34 psi turbo will only hold 26 psi am I better just turning the boost down to get 28 to 29 psi spike

 

As long as you're not seeing knock, you should be okay..But consult your tuner. You must be on e85?

 

How much timing are you guys running with cams on 91? I installed some S2s and have picked up power, but having to run much less timing from 6k up. I can squeeze out 7deg at 7k sometimes. Was 12deg before cams.

 

how far did people make it with their stock turbos? on evo 8s specifically, ive heard they are only good for like 300 wheel is that true?

 

also what should i expect to make on the dyno? I have an evo 8 running hks 272 cams, walboro 255, turbo back, big ets front mount, full intercooler piping kit, and intake? stock injectors and stock 8 turbo. right now im running around 20lbs of boost
