How much hp can a garrett t3/to4e turbo produce
with a A/R .82 exhaust, .60 intake and stage 3 wheel?

 

.50 A/R intake just refers to the size of the TO4E compressor housing. It has nothing to do with the wheel inside. That turbo could have anything from a 46-trim TO4E to a T68 compressor wheel inside of it, so there is no way to answer your question without more info.

 

Yah, we need to be know what trim that turbo is. Without knowing exactly what the compressor trim is then it could be anywhere between 350-450 WHP, maybe more.
