If your Familiar with the SBR GT-12 Turbos Dyno Results please come in

[Boost95]

I'm looking for some people who have info on the SBR GT-12. I have had this turbo for a while and finally got to the dyno yesterday. I'm interested in what kind of number people have put down and some 1/4 mile times.

I have all the supporting mods for this turbo. A quick list: stock block, fp2cams, 3" exhaust, 2g maf, 880s, 255,afpr, JMF SMIM, SBR FMIC etc.

I only put down 325 AWHP!! Thats 16g power! I had 2 other people look at my logs and they looked fine. I was expecting 350-400 easily!

Here are the specs I know on the turbo.

The GT 12 turbocharger is rated from garrett as a "500 HP" turbo, but spools extremely fast due to the highly efficient turbine wheel designed by Garrett in racing applications since 2000. All SBR series turbo's are made to mount directly to your existing dsm manifold. This is done by utilizing the SBR cast turbine housing specifically designed for the medium frame GT30 series family of turbochargers.

Compressor wheel facts:
56 "trim" compressor wheel
2.24" inducer
3.00" exducer
55 lb/min compressor wheel


Turbine wheel facts:
2.16" exducer
2.36" major


Thanks for any input!

how much psi?

 

[bastarddsm]

what fuel? Run your tank empty fill up with E85, give it 12:1 AFR's 13*timing at 5500 going to 19* at 7000, and 25psi. You will shit your pants.

Pump gas. 30psi ish No knock 14-15* timing up top. 49ishlbs./min

Thats odd. I'm flowing less ~44lbs/min with less timing and making 415. I am on E85 though.

go to the track and see what it traps.

What kind of dyno? As said before go to the track and get a good trap speed and weigh the car and you should have a good idea where it sits for power.
