Before and after dyno of T1R pulleys for Honda S2000
Really pleased with the T1R pulleys. There was a huge mystery of how much hp and tq these lightweight pieces would make, so I dynoed them just to see. Same tank of fuel, nearly identical weather conditions (which wouldn't matter much anyways since it is corrected.) While the "quantifiable" gains are there, what is gained in terms of engine response is what truly makes them special. These lightweight pulleys only seem to make the S2000 engine more S2000-like, livelier, more responsive. So much that I have absolutely no regrets of going the NA route. Anyways, for all you dyno-queens ;), the dyno:
Blue is OEM, Purple is T1R

3.1hp and 2.2lb-ft torque gain
