Bypassing the AC Unit

[B]There's no relationship between rotating mass and the AC pulley (except the insignificant parasitic rotation of the pulley (which probably weighs six ounces in total of which most is inboard). Remember, the A/C cuts out under load even when it it on. The compressor doesn't turn at all when it is off.

As already noted, I can guarantee that there will be no percievable (or dynoable) power gain by removing the AC system. Further, the weight saved is not worth it unless the car is being stripped for track. I will be money that all the AC components (condensor, evap, compressor, lines) weigh in at less than 20 lbs, more than likely only 10-15, max. I believe for the 5th gen Prelude they weighed in at a grand total of 14lbs.
Pro Autosports offers an AC Bypass belt for the S2000. www.proautosportsinc.com
I also saw an ac bypass belt from SPOON but it was really expensive ($160!). I used the belt from Pro Autosports and removed all of the ac system components forward of the firewall. I weighed each component to the nearest gram and the total was over 27.5 lbs. That's a pretty good lb/$ ratio. Plus, there is less inertia to rotate when accelerating. Besides, it's a convertible - who needs AC
(at least in the Northwest)

funny how they didn't start selling one till this thread came about because I've seen that page before and it did not have that belt on it.
Good never the less but a little expensive.
