How much power and psi is this turbo good for? It's on the truck im buying.

 

With a 1:00 A/R Exhaust housing 450-475hp With the 1:15 You can go a little higher (500 to 525HP) but you will get more smoke with that HP numbers.. But if you want to go higher yet you have to use a GT47 or GT55 to feed the 38R

As for boost they are good to 40 PSI, BUT your turbo will like you better if you keep it 34 and under

 

500 or so give or take. If you want more you can get a bigger single. You don't have to run compunds.

Ok cool thanks guys it's going to be awhile till I get to those numbers but at least I won't have to buy a turbo

 

yep they are a good turbo. BB so you get good spool up.

 

Good proof is Brian Jelich, best pull was 992HP with a single turbo, and tweaking for 1,000+.
