ok im stuck between to4s and the apexi, im lookn for a turbo wich is still stretable, but will be able to give me 475-500 rwhp @ 20 psi.. i know of the t04s wich laid down 470, but i havent seen anyine run the rx-6 above 15 psi.. would the rx-6 be comprible @ that boost level? or should i stick with t04
ive ruled out the t-78 and others...im not lookin for redicloush hp or a full drag car,
but back to my original ques..anyone?
if not dose anyone have dyno sheets on a fully worked motor, ext with t04s @15 psi?
thanks

 

I know that it will run out of effiency at about 20psi, and will probably not make more than 450rwhp as stated by apexi themselves. You wouldn't want to run more than 18psi on pump gas anyways. This turbo is great for the street and has lots of power down low as well as top end. The ball bearing design is suppose to be nearyly indestructable and gives good response. If I was to go to another turbo, since I do run the rx6, I would probably try the t04s. Either way you will be hauling.

 

yea im thining 16 pump gas 22 on race fuel
to4s seems to be the winner, ive heard from others that its power is like the t-78 but without the lag..

 

I race mine at 18 psi on the track on 89 octane + a can of octane boost.

But keep in mind that I have low compression rotors and a Haltech tuned to the rich side.

I've never tested my car on the dyno at above 15 psi... One of these days I'll get off my lazy butt and do it. But I think that 450 RWHP is probably what the RX6 will max at around 20 psi.
