Thanks for the info! St80 is huge though! Dunno if I can fit it. I've got maybe 10" in diameter I have to work with at absolute most. I guess the PT88 is about 9-9.5" .

I said .96 because I believe that is the largest housing available on the 76GTS.

If you only want 650hp now and 800 later, no reason for a PT88. The 76's can make the power you want.

My car with a TC76 is making enough power to go 135+ in the 1/4, and my car is 4400 lbs race weight. And the 76GTS will make plenty more than my lil TC.

Here is NicD's 347 on 15.5lbs of boost with a 76GTS. This turbo will get you mid to low 9's depending on your setup and is good for 800-900 rwhp through a manual. The ST80 will get you low 9's to high 8's if you have a well dialed setup. DrTurbo said the ST80 is 10" tall.

PT76GTS = 105 - 110 lbs/min ??
ST80 = 121 lbs / min
PT-88 = Around 120lbs
10.86 x lbs/min of air = hp

Makes me lean towards the 76gts. I'd be happy in the 10's. That should do it.

76gts can be upgraded to 78 mm and I'm pretty sure also 80mm. I've seen a Ford 347 make 840rwhp with a 78 gts 20+ Psi and race fuel.
