500hp turbos- part 2

[sandman1111]

Got better specs and pics of the turbo. Some info was wrong. It has 54/76mm compressor and 74/62mm turbine with .48 a/r housing. Could be quite early spooling..? New modified turbo with watercooling.

Do you think .48 housing can make that much power? It has quite big turbine, so it might be ok. I think the back pressure goes true the roof. Sure it will spool fast, but making big power, I´m not so sure.
If you guys want big power and fast spool, try Borg Warner SXE turbos. Maybe can find a open t3 housing for them. If there is something that will fit. I would never consider any Garrett or Holset, IF buying new, and going for 400+.

i seems that the inlet house is from a gt35....

I'm not sure what the base is on this turbo, but it's a custom build with both compressor- and turbine housings machined. According to the seller, it can make 600hp on a sr20det engine with great responce and spool, but I'll guess it would be with e85.

i had a gt3076r 0.82 A/R in the past and i was very satisfied with the numbers,520hp and 635nm torque,full boost(2.0bar) on 3800 rpm

Trying to decide for a turbo in 500hp range for my 80q. One alternative would be Holset HX35 Super, but I have been offered a Garrett 52/62mm, .63 A/R. Any thoughts?

It was a bit laggy for me. Might need to look into a new turbo and cams

[Quattronaut]

Pretty cool numbers, should be fun to drive :-)
What is torque & hp loss at the RS2? Around 80hp?
Do you have boost numbers for us?

Only 453HP at the flywheel?
Or is this at the wheels?

Because is a GT30R, right?
