Is a 20% pulley reduction safe if done right?
I have been looking at the Kavs motorsport 20% pulley reduction to do to my 05 r53 and im wondering if anyone else has tried this. I plan to combine this with my own water to air intercooler (different discussion) and my stage 3 snow system water method system. I feel these combined will solve the problem with excessive heat.
Another issue I hear is belt slippage which can be solved with several of the adjustable belt tensioners that are sold. Also I heard someone say once about a "sticky" belt which I would assume has better grip compared to oem and I'm wondering where I could buy one. My water pump is also new (gates).
My supercharger is freshly rebuilt with new stronger pto gears and 3 warranty and also I am not a race car driver so this won't see constant redline.
Will I need bigger injectors? 400cc? Tune?
Right now I have custom header to tips exhaust, ddm intake, Detroit tuned bpv, fluid damper, Msd coil with ngk iridium.
