Default Garrett TV7511 71mm Turbo

Has anyone ever run this turbo on a 6.0l engine? I cannot find a compressor map. I want to run about 10psi. current RWHP is 413.

Plain on using truck manifolds.

This is what i found
71mm and rated at 850hp
Garrett .96 a/r turbine housing with an S-trim wheel.


Thanks for any help.

if you can buy it cheap, snag it up and send it to forced inductions, have jose put ya a 80 or 88mm wheel on it i had the same turb and sold it freshly rebuilt awhile back for around 500ish, wish i would've kept it and had it upgraded instead go on forced induction site and check out how big they can make those turbs, its neato frito lol

not a bad turb at all, very beefy built! i ended up having f.i. build me a et-r wheeled 80mm 1.1 ar small turbine s480 instead of runnin the same turb you have. in hindsight i could've spent alil on the garrett and made it huge and put out low iats. the garret will get r done as is tho, when i had mine i figured bout 700hp on a 5.3

I ran one for a bit. It was big, spooled a little late, but was did 15psi no problem on a 346.

It was like an on/off switch.

I think they're 76mm.

I have a simaler turbo on my setup, its a garrett TH08a64 off a detroit diesels semi.
Mine is..
.96 A/R hotside T6 flange
.95 A/R cold side
And around a 74mm wheel.

I made 585rwhp on 8psi on my 383lt1 through a th400 with it, and im not sure what I made on my current motor but I was maxing 94% duty on my injectors at 4800rpm on my LS motor on 10-11psi
