I know there's a mega thread for this but I'm basically trying to see where I'm at power wise.

03 Evo 8
Injen intake with K&N filter
Custom Upper and Lower ICP
Stock intercooler
Test pipe
Full turbo back exhaust
tuned to about 24psi conservatively

I'm thinking right around 300?

 

315ish, all depends on the dyno.

I would add a walbro 255 to that list

 

it might have one I need to look. this is just the stuff i've found so far lol. I'm going to virtual dyno it with evoscan and see where im at too.

Plan is evo 9 turbo fuel pump injectors and e85.

 

whp? right?

 

My 03 viii made 306whp @26lbs when I had close to the same stuff back when I got the car except I had an ams front mount and hks turbo back and test pipe.

 

Granted I have a 9, I have everything you listed plus a 255, and I put down 330 at the wheels on a dyno-jet.

 

high 290s low 300s

 

It really all depends on the dyno though, that's what will change the numbers. Don't be worried about the numbers so much, be worried about how the car drives and how the tune is

 

HP doesn't matter, car will be way different after those mods. Enjoy
