Yeah an ST80 is a bad boy. Most are making 800+rwhp with it.

What is the physical size difference between and ST80 for an GT 88?

Any idea what fragged your D1 blower? Did it eat something or gearbox break?

I thought the t78 would make over 800rwhp? The 88 would be a good race turbo but wouldn't the t78 or tc78 be a better all around turbo for the street and strip?

I was under the impression that the t78 was good to around 900rwhp on a 347?

Well after looking at the compresser map I guess the pt88 is perfect for his rpm range. I shift at 5800 in my truck so I guess I can get away with a little smaller turbo and stay on the map.
