So, are you not getting full boost until 4500? Much more lag than stock full boost at 3000. I know it's hard to push 500hp with a boost that comes on at 3000 or 3500, but I sure like my bottom end and almost instant boost. What's the A/R on the hot side?

 

...as I've said before, I'm looking for over 400whp on 93 octane. I don't want to give up very much bottom either. It seems that the DSM guys have a few options to do this. It is just a matter of finding someone producing the castings for our application.

 

All you need is the very manifold that SFP has posted pictures of in this very thread. if you guys cant deal with 400whp which comes out to around 500fwhp that spools around 3600-3800.

then my suggestion is to keep the stock turbo and be happy with 330'ish Whp on pump. These GT30-35R turbos that these venders are trying to stuff down your throats. Make horrible numbers on pump gas and at sub 30 psi boost levels.

 

I can live with 3600-3800 easily...

 

hey, is my greddy bov, supposed to flutter when i let off the gas slowly? everyone is telling me its bad for it.

 

My friend's s/c 00 Si has about 240-260FWHP and traps at 105-106 in the 1320

 

On the contrary, we've made over 400wHP on the GT35R on pump gas at 18psi. Then we realized we had a wastegate leak. There is alot to be had out of the GT turbos.

 

was this on a 4g63 or honda motor?

 

the downside of the GT35R is that it spools up at no less than 4400-4500 rpms. Great for the track, bad for the street, at least that what I feel.
