Ive read of people getting up to 250whp Max on the stock turbo , what are your mods.

I made over 400rwhp on a stock S4 TMIC 7/8 years ago...

Heavy methanol pre turbo injection, and 23psi

 

aside from the others I already put on. not much. just a fuel pump change. some better plugs and a dyno tune. the rest of the mods have been made for handling and stopping. oh and I've taken the air cob compressor and condenser out

 

Ill be doing the same set-up on my S4 in a few months, will see how it holds up and how much i can get out of a stock intercooler and stock turbo, after market 3 in exhaust and maybe a air intake

there was ice on the intercooler , carefully see the vid...ijs

 

I own 13bpower's old S5 which he claims was dynoed at 296whp which has a stock ported turbo. However recently the car dynoed at 260whp and 129ft lb. A/Fs in the 18s O.o

 

With the stock Turbo there's no way you'll make 296whp.

225-250 whp is possible. You're only getting 260 because your car is running lean.

"Leaner is meaner"(until your engine grenades)

With more fuel (running the right afr) it'd actually have less power but you won't have a blown engine from detonation .

In the 18s and didn't blow up?

 

No. It's a built motor. Still, I'm barely driving it and I never boost whenever I do drive it. I'm overhauling the fuel system right now so it will be fine.

 

It doesn't matter if the engine is built the stock Turbo can only flow so much

Yeah true. But I was talking about the motor detonating from the lean a/f.

 

Pretty sure you can modify the stock turbo to get more than 290 hp or so, but it gets expensive. Those are some good numbers though. That's a lot of power for the application.

 

If its modified its not stock anymore lol

I see you picked this line up from one of your own threads lol. :P

 

Haha yep, can't wait to get my car running.

Who drives a stock rx7 anyways? I would never lol
