think it's an old btcc head, like early 90s.
Numbers shmumbers....over here so many recent builds run on anything other than a dynojet seems to be coming up low.
this as well as 2x high comp, n1 20ves at 175whp, few other 20ves and de's. Our UK figures recently seem to consistently as dale said recently to someone, be about 20hp lower than US figures. Just they way it is, dyno's suck.
I think this is awesome, and the torque figures are fuckin ace!
