Just wondering how much horsepower this can support at a pressure ratio of 1.5-2.0 (7-15lbs. boost) on a 383 cu.in. making 450-500 N/A h.p. Thanks.

 

that doesn't tell us anything....you need to measure the inducer of both the compressor and exhaust wheel

Well.............thats a start but he still needs top measure the wheel, hello 92z where r u?

 

It's a turbo I was considering buying. Garrett p/n 465366-18, s/n ke1019, AT04b81. Compressor side .60 M27, Turbine side 1.00. Don't know the wheel dia.'s. From what I have dug, it came off a Mercedes(diesel?). I think i'm going to pass, as I don't believe a single T04b from a diesel will support enough flow. Wouldn't a turbo for a diesel be efficient at low revs, since diesels don't rev high? I think on a small block it would be out of its efficiency range. That's why I was looking for a compressor map. Looks like I may need a t-76 or so. Any suggestions? Right now I am researching, but hoping to get started soon. Looking for around 600hp at anywhere between 7 -15 psi. Thanks for any help.

 

that is going to depend on how free flowing your intake and heads are

the part numbers on turbos dont say much, you have to know the measurements

 

well what you should do is to get two of those turbos, and then that would be enough to feed your engine

 

A 66 may do the trick. If you wanna be definite and have plans for a higher stall(if auto) and better heads and fuel down the line an 88 would be a rocket. This all depends on the setup...
