Turbobocharger Gurus Needed.
Im currently trying to find as much info as possible but coming up rather short. It is a holset HX52. I believe it is a 67mm/71mm turbo and it has a larger T5 backhousing. Ive heard that it is a 1.30 AR housing but I havent seen any solid proof.
What im curious about is what do you think this style turbo is capable of making on a little 5.3
I know that every setup is different (cam, heads, etc.) But what I'm curious about is what you think it's effeciancy range on this big of a motor is. I'm hoping that near 650whp is capable through a turbo 350 and an 8.8
Give me your opinion. The more the merrier, Thanks Guys.
