View Full Version : NST pulley's

11-12-2007, 10:55 PM
I just ordered the NST crank and water pump pulley's from their website. I went with the standard size (OEM). I wanted to get either the 20% underdrive crank pulley, but didn't want to risk cooling problems, or get the set up i just ordered and run the 20% overdrive alternator pulley, but don't want to have charging problems. I wish they had a stock size alternator pulley. Are the 2 concerns I mentioned (cooling problems, charging problems) valid, or am I being stupid? :doh: Any opinions? Thanks

IMO your concerns are valid. At least you didn't go for the OD/UD sales BS.. Good luck.

well, just got it all buttoned up. pretty easy install! i bought a serpentine belt tool ($50 :doh: ) and used it on the spring assy and a 19mm on the tensioner and got the belt back on myself. well worth the money. the hesetation has been reduced A LOT and the weight difference is amazing. pulls a lot harder too, so i'd say that NST's hp claim is pretty spot on. at least thats what my ___ is telling me. well worth the money!! :love:
