One question... my mods in evo 8 is one turbo-back exhaust ralliart 2,75'' and down-pipe and test pipe 2,5''. More diference in hp and torque with one exhaust in all 3''?
My future mods is turbo IX, GSC S1, with my exhaust run better or need 3''? thanks!
My hp and toque is arround: In wheels 280WHP and 270THP on 23psi-93oct. In engine is 340HP and 330ft/lb.

Sorry my english

 

I've made over 400whp and gone 11s on pump gas on full 2.5" exhaust with my DSM, most people will tell you that you need 3" but I'd say since you already have a setup stick with it, get your other mods done, see what kind of power you make, then worry about it. Maybe you could borrow someone's full 3" setup later and swap it to get a before/after comparison and go from there.

 

Ok! with my exhaust run better, ok ok.
With my future mods --> Turbo IX Magnesium + GSC S1 + 93oct + my exhaust 2,5+2,75'' and good tuned = WHP and THP in my evo VIII???

 

bump! thx

 

up!

 

will be close to 380-400HP (engine) depending on air temp. I would also do a fuel pump at the same time - thats a nice package...

 

Ok! In my evo in this moment with walbro 255.
Airtemp arround 60-65F in my country. With my future mods, only gain 60hp to the engine or 50whp to the wheels) ?
