Default pt76gts numbers?
Havnt been able to find a great amount of builds with this turbo. If you have some dyno /track mph numbers (psi?) Im curious to see how it reacts on diff size motors.

12 psi. I would recommend doing a larger turbo, but this guy was set on trying it.

150 is flyin! This turbo seems to work reeeally well with smaller v8's. I bet the 5.3 could make more power then the 6.0 w/ this turbo.

That is true with almost all turbo's, but there are some exceptions.

3750 lb, 388 cid LTx with a TH350 and loose converter:

9.9 (1.7 60' leaving soft) at 146 mph and 700 rwhp, all at 17 psi. There was still more in it, as the turbo was capable of 20+ psi.

Most say the turbo is too small for 388 cid, but I had good luck with it.

Also... we ran a similar combo on an engine dyno. It was 377 cid with a 230/230 cam and air/air and made 930 hp and 1070 ft-lb at 18 psi.
