If you plan on not having to rebuilt the motor as often, I'd go with one of 949 Racing's harmonic balancers. Its not a quite a light as the underdrive pulleys, but it will do the job and reduce the stress in the oil pump and crank.

Well I mean there are Blower kits and turbo kits that only make like 160 wheel so yeah, some of them actually do make more power than some boosted cars. If the car only does CSP its going to take it a while to work up enough time on the engine for the light weight pulley to kill it. Put it in perspective there's CPS cars that have been reving to 8k and have lightweight pullies for multiple seasons without blowing up. Course those are towed to the event.

I remember Bill Schenker posting he was running the miata roadster superdamp and was pushing 77-7800 SAFELY (99 motor with 01 head and weight-matched internals). And supposedly 7900k is the "line of doom" for 01+ motors (vvt) with stock internals. Apparently the 94-97 motors can do 8k regularly w/o exploding? Can anyone confirm/deny? -Just reposting what I've seen csp pr0's say about their setup. But then again I'm still running my 1.6 so wth do I know...
