Silverninetythreee made 435rwhp @15psi and 470rwhp @20psi on the gt35/40. As a-spec-tuning said, you will typically see 15psi by 3300rpms, which isn't that far off stock and obviously much quicker spooling than say a t-78.

How long did his motor last??

He had some sort of a tuning problem and blew not too long ago. You'd have to ask him for exact miles.

550 @ 18-20psi.....wow, that would be something to see......i like the sound of that...

uhh, from what i have seen, dyno charts, the gt35/40 has about 75 hp at 3k rpms, and the rx has about 100 hp at 3k rpms, that is a BIG diffrence, stock is about 110 hp, t78 is about 75 hp at 3k rpm as well. and the t04e is about 100 hp as well (non ball bearing) as u can see the rx6 and the t04e are about the same producing about the same hp up top at 13 psi about 360 at wheels.



i really dont see how the gt3540 is a fast spooling turbo other then when it starts to spool it spools faster then somethign say a t78, the gt3540 gives u a better spool and more power sooner, but the t78 has a better tq curve.



now u decide what u want https://www.nopistons.com/forums/pub...DIR#>/wink.png

Well not exactly, I made around 75rwhp on my apexi turbo at 3k rpms. Silver ninety three also made about 75-80rwhp at 3k rpms on his dyno sheet using the gt35/40. Compared to Vosko's t-78 dyno I made 20 more rwtq with the apexi turbo, so the t-78 doesn't necessarily make more torque than the apexi or gt35/40 (at street boost levels). Power potential for the gt35/40 and t78 is much higher than the apexi turbo. Porting has a large effect on some of these low rpms power numbers. I'm more concerned with power from 4k-8k than from idle to 3k, 75rwhp is plenty to push me to work and back everyday.

I have a Rx6 for about a year now, and I have only positive things to say about it. I have had tons of mods to go along with it, but I have gotten 467 to the rear wheels, but that is at 18psi. 14 psi I get 411. I consistanly run in the low 11s with street tires and I do many trackdays and it works very well. It is a killer set up for autoxing. There is almost no lag. ( just my two bits)
