Oversized S/C pulley question?

mr2tim · 10-27-2009, 02:44 PM

I'm in-process to obtain what is called the 180mm crankshaft pulley and a changed sized water pump pulley for the S/C racecar.

Do I need to look for a "revised sized" belt tensioning idler wheel to complete this installation? Or, can I expect to use my OEM setup with the revised belt?

(I ran the 10psi HKS pulley for 8 years in competition with no problems and would like to step up the output with this "new" engine.)

Thanks for your experienced response.

usually the o/s pullies come with a new tensioner. there have been some discussions regarding aleternatives, but i've not had to cross that bridge.
