This i what i can reveal. It's a B20 stroked. The motor has reved 10,000 many times. Currently it is reved to 8,500rpm. The car is making 150 torque at only 3,000rpm. Problem is it cant breath up top. the car needs alot more air. We must put individual tb's on it. It peaks hp at 7,500. So reving it past that point is useless. The head and rest of the motor are set up to flow up the 330whp. @ next stepps are the throttle bodys ($2000) and then to go to Alchohol for fuel ($2,000). These 2 mods should net around 50-60whp.
