Better late than never I guess...

FP3052 turbo
On my Stock bottom end 2g DSM (8.5:1)
1g head with HK$ 264i/272e
Stock 1g intake manifold
Greddy Profec-B boost controller set to full gain

20 psi @ 3750 rpm

25 psi @ 3950 rpm

I have been road racing on 3076Rs for 4 years now. No complaints here.


For sake of completeness:

Fp3052 has .60 a/r compressor .70 a/r turbine

FP3052, HK$ 3037S, and Garret 3076R are all the same center section

HK$ and Garret you can get the compressor in .48 or .60 a/r. The .48 is for guys who want faster spool at the cost of decreased top end .60 is obviously for better top end.

You can also get HK$ and Garret in various a/r hot sides.

Something was obviously wrong on the setup for that late spool.
