I'm interested in seeing what everyone's route would be to obtain 400whp or near it from a stock Evo IX (Building up from this, stock parts can be replaced of course). Money aside, what parts and brands would be the quickest way to 400whp on pump.

 

I don't believe I've seen a dyno from an Evo with stock turbo hitting 400. Is this possible??

 

ported everything,exhaust,fmic,fuel pump,injectors,tune,clutch - done

 

Lots of info on here for you to search... anyway, bolt-ons with cams and meth should get you around that if not a little more

 

Easy enough.

 

You can get 400 with out meth. full bolt ons, cams, ported everything, and running 25-27 psi on an aggressive tune with acheive that. I wouldnt recomend it tho

 

i think the key thing is all the boltons and then the cams. Seems without the cams you will only get close. Meth just will make it alot safer with a much less agressive tune with just as much boost.

 

Im trying to do this and seeing how much could be made without changing internals (cams mainly) Stock injectors, Stock turbo, Stock block.

 

with meth, you will be running an aggressive tune. Lots of timing and boost, which means if you ran out and didnt have a good failsafe, you will be building a new bottom end.

 

One of our customers did 407whp on 93 pump. And stock turbo of course.

 

i was around 318 torque with just a TBE and tune. Now I got meth and my goal is 400HP. I will let you now soon what the outcome is

 

It is possible.

 

I'm at 389/367 with full bolt ons, cams, an FP Green, and 93 octane only @ 28 psi --- Thanks to a conservative road tune from Mellon Tuning. And that was on a dry 86 degree Memphis day, heat soak all around! No meth required either. I'm sure with a more aggressive tune, we could close the gap on 400 whp --- all on 93 octane.

I'm just not willing to run it on the ragged edge, but if you want --- Mellon can easily make 400whp on pump a reality!

 

You will have to change ur fuel pump and maybe injectors. You will not get 400whp on a stock car and meth or if you do it, it wont be safe.
I think you will need the following for a reliable 400whp plus:
Meth kit with all the failsafes and some failsafes for the failsafes...
cams 272's
O2 housing
Full turbo back exhaust
ported manifold
injectors
fuel pump
boost controler @ like 29psi
lower intercooler pipe and upgraded intercooler (stock will be overworked with the higher PSI, so this is for consistancy on power)

You will have a killer street car with these mods...

 

FP Red...Your not gonna get 400 on stock turbo w/o Meth, and even with a good tune and failsafes, it can still blow ur motor if u decide to use the Meth
