Anybody using this, know anyone that is, or know anything about them? And does both Garrett and HKS make them? TIA

No one?

 

what you wanna know? I have a freind using one. I have used a 52 trim GT30 wheel.(hks GT3037s) the one you talking about is probably a 56 trim GT30. cabable of 65lbs/ min in a 6 blade wheel.

I have a 56 trim 82mm compressor in a t04e housing with a T4 turbine waiting to go on my drag car.

 

I think they have it in a 52 and 56 trim, which flow 50 lb and 55lb respectivly. http://www.store.yahoo.com/sr20perfo...gargt63ar.html thats the 52 trim. Im wondering about what sort of lag am I looking at with this turbo, and what sort of power its capable of.

 

find a compressor map

 

Easier said then done.

 

there might be one here

 

Thats the turbo, but no compressor map.

look at the bottom of the page for the 56 trim GTseries compressor map.


power capability with the 52 trim is 500-550rwhp

power capability with the 56 trim is 600-680rwhp. these are wheel hp numbers. People who have bought the turbos with the 56 trim 82mm compressor put on the dyno at high boost and put down 680whp.

Of course these are the top end of the power spectrum. As i said earlier i had a 52trim compressor and put down 457rwhp @20psi. Spool up was about 4,500rpm for 15psi. 4700rpm for 20psi. This was on a log manifold, a correctly designed manifold may have helped spool up.

 

Holy crap, thats alot more then what I was looking for!! Do you know anything about the GT25? I have heard concerns about the turbine/compressor match.
