The turbo is sitting on a Full Race divided manifold, twin wastegates, and Full Race's 4'' down and midpipe.Catback is a Apexi GT.
Converted to a OBD2 ecu.A HKS VPC and Apexi Afc control fuel.
A Apexi AVCR controls boost.Set to 1.5 bar of boost on the street.Only hit 20psi on the dyno.Aquamist WI triggers at 10psi.

Great curve !!!! Looks like with more boost and race fuel or E85 some pretty decent numbers are attainable from such a tiny little turbo

No way... everyone knows the Borg Warner EFR/Full-Race stuff all sucks! This can't be real. :nono:

Congrats Philip! Looks like a killer setup, I bet it's a blast!!! Now go spank Steve's 911 with it. :)

This turbo is much smaller! Even still, an S366 should be putting the hurt on much sooner than 4500rpm.

Amazing results for a stock compression motor on 93 pump.
Drop some larger injectors in and maybe switch out to a walbro 400 pump and you should be fine.
Congrats.
I agree. A bigger pump with a regulator should be a good aid until a full fuel system is put in.

So should make 650ish on race gas w/ the boost cranked and some cams?
I would say that's a definite maybe. When we did the 8374 (62mm comp inducer) testing, we made 796whp and 815wtq with peak power made at 30psi (boost peaked to 38psi, fell to 22psi). That turbos flows 79lbs/min and proves it on Craig's pixie dust motor. On your average 2JZ, expect a bit less out of it. The biggest factor you're going to fight is holding boost. As you can see from the boost numbers I just referenced, the boost on these smaller turbos falls off dramatically when we try to really push them (and this is with external wastegate setups, not the internal EFR one).

Carrying this data over, I'd say that the 7670 (57mm comp inducer) which is rated to 64lbs/min will likely be able to make 580-600whp on your average setup and come close to 650whp on a "pixie dust" motor. As I said, getting the boost to carry throughout the powerband will be the determining factor.

By the way, that's a very nice tire-shredding torque curve!

It's about time somebody got one installed. This turbo is a 57mm. Very responsive looking curves you have there. I'd love to see what their 62mm does on a stroker with e85 on a cast manifold. Would love to see that.... :p

Philip, is that Swain Tech white lightning coating on the manifold? That stuff is awesome!
