We did some minor tweaking with the accel enrichment once I got to Houston, but overall it runs good, and I am pretty happy with the power.
On 91 octane it put down:
235.7 HP @ 5000 rpm
264.9 ft-lbs @ 4000 rpm
On 93 octane it put down:
242.4 HP @ 5000 rpm
280.2 ft-lbs @ 4000 rpm
Those numbers are wheel horsepower and torque. Stock STi puts down around 250 hp & torque to the wheels on their dyno.
You can see from the plots that the heads really are the limiting factor. But I can't complain too much as the motor is making nearly as much HP, and MORE torque than a DOHC head with much larger ports & valves.
As some of you may have noticed in the engine forum. I've got a thread about some cooling system issues. I think it's a head gasket, but will wait until I test the coolant for hydrocarbons. Surprisingly the engine runs fine. I just don't think the stock head gakset can hold up to 20 psi of boost. Plugs are good, so no real signs of bad detonation. If I have to pull the head gasket I will probably try and get the heads to flow a little more with p&p & cams (I'd be stupid not to...haha
