hmm..i have the same problem, not meaning to whore or anything, but i have a 93 GSR with a Jdm B-18c, on the track my best was a 15.1 at 94 mph, ive got two friend's, one with an old cressida, and one with an RSX, the cressida put out 142.7 to the ground, and the RSX puts down 180.i can tare the cressida a new asshole, and the RSX will take me by a length and a half.i havent dyno'd i have used a computer program called desk top dyno. its mostly accurate, and say's i should be putting down 178whp. how in the hell is the rsx pulling me the way he does, i am a fairly decent driver, never grind, and i know when to shift, and how the feather the clutch from a dig, i can pull a 2.1 in the 60ft on street tires..
