Cliffs:
-N/A 3.0l H6 motor.
-GT35R Full boost by 3500 RPM
-92 octane pump
-Car is making about 430whp, and 410lb-ft of torque, on only 16.5 PSI! Torque breaks 300 lb-ft at 3250 RPM
Forget big 4’s this sucker will fit in STi’s and Legacy’s and judging by the dynos subaru H6 heads appear to flow great.
What is next?
"We have two more H6s going into cars in the next few weeks, and are doing some significant upgrades to make more power. The block is getting sleeved, we have replacement rods, and the heads will undergo some head development. The cams need some work to extent the upper end power, and the dual lift makes multiple durations possible. Both of these cars are 02 WRXs, using the same Hydra setup, but drive by throttle. We will be building several standard H6 exhaust headers for different turbo configurations. The H6 going in my car is going to use the GT40 Twin Scroll turbo with the real 1.34AR turbine hotside. We are also working on a turbo H6 for the Legacy, which would be one bad a$$ legacy. "
