With these mods:
Intake, Downpipe, Midpipe, Cat-Back, Power FC, and 11psi??

Also, Would upgrading the fuel pump without using a fuel pressure regulator cause me to run too rich?

Thanks Guys!

 

From what i have learned from this forum, Tuning is everything on your FD. Get it tuned right and im thinking about 330rwhp. more or lesss.

 

I would say some where around 280 rwhp. You need an IC to keep the intake temps down. Also you might be close to maxing out your injectors. Get your self an IC and tune the pfc, but you might want to consider upgrading your injectors as well.

 

Why don't you look on my dyno comparisons page for an idea?

Try to find a car with similar mods to yours.

Also, adding a bigger pump will not cause you a problem. You already have a fuel pressure regulator mounted on the end of the secondary fuel rail near the firewall. As long as you don't add some totally huge overkill pump I am 100% sure it will be fine.

I have dp, mp, apexi cb, intake, ic, pulleys, ported wastegate, pfc, 13psi, injectors, fuel pump, light weight flywheel, clutch, and other non-hp mods. I expect to run around 330-350rwhp (I'll post in a few weeks when I get it all back together). You will be ok if you only run 11psi but after that I would worry about the injectors and fuel pump. Throw on an intake and you should be around 300rwhp. Also, heat soak on the small stock ic will only hurt you.

 

I also think you will be about 300 rwhp. You are not street-ported and you have the stock IC. Also, unless you are tuned extremely rich, I see no need to upgrade the injectors or the fuel pump. What are your injector duty cycles on your pfc?

 

My duty cycles never exceed 78%.

 

You certainly do not need to upgrade your fuel system then.

 

Drove another one down here in NZ last week with similar mods running 14 psi and that was in the 320 on the G-Tech range ...

That car does have Water Injection also though ..

 

wow you guys just got me really excited, those are the same mods i have. now if i could only get my car to run.
