On a stock/streetported S4 engine....
I am aiming for about 350WHP at 14-15 psi on my stock port S4 engine, is it possible?

I will have a microtech, alot of fuel (PUMP GAS) and a large FMIC to help me out :-D

I am going to the dyno at the end of february and just want something to compare with. I you'd like to, please write som tips and some good advice about the tuning of this setup.

On the y axis its the pressure ratio, on the x axis is cubic meters/second I think.. Im not sure, I havent really played with mitsu turbos yet.

Anyway, jsut playing with it... youd be way out of the efficiency range of that turbo (assuming 400 flywheel hp to get 350 whp, which would mean about... .28 m³/second according to the little applet at http://www.rbracing-rsr.com/turbotech.html) trying to get that much airflow at that PSI.

Youd probably need a bigger turbo to get where you want.

Actuall I think the TD-06 20G kit would fit right into that neighbourhood on stock ports

the parts car I have outside used to have the exact kit in it and it has dyno sheets in the back with 339hp pulls WITH A TOP MOUNT I/C (guy must've been a ******* nutcase)

I think that kit would net those numbers for sure

I thought so to and i really hope it will get me there!

i think that would easily reach that goal.the guy that i bought my s4 from has the same kit and i think he at 350 -360 at 16 psi, he has the complete kit from greddy.

Does that use something similar in size to a small t3 turbine side? I have seen the kit for the fd in person, but not for an Fc...

It is the complete kit i've got, manifold, turbo, wastgate, downpipe and soon the fmic kit.

Dont really know about the turbine ...

And whats the difference between the mitsubishi TD06-20G and the greddy TD06 20G?...
I know its the same core but did greddy do anything to the turbo except for the label?

just a label and different other parts.........turbo is pretty much the same

in fact most are, greddy doesn't ACTUALLY make a turbo, nor HKS, nor APEXi....they all buy from turbo mfr's
