would they free up noticeable power? the trans has 144 thousand miles, texas highway miles by middle aged couple. unsure of vehicle history so im cautious of any powertrain upgrades. i cant seem to find good info in these topics regarding the Series 2 N/A... this other site, 3800pro.com has so little trafic on its forum, it takes weeks for someone to respond to a post. my longtime forum houston-imports.com has crazy traffic. go there. lol.

I had the water pump underdrive pulley and the alternator one even though I never installed the alternator one on my old GT and i did notice a lil something.The car revved a bit faster and had slight more pull towards mid range,top end. But they arent really worth the cost. Id say skip them or if you wanted to find a used water pump one.

underdriving a water pump is silly

reason? different rpm affects water transfer?Originally Posted by Seachicken

you reduce the pumps output at all rpms, for minamal gains

i can heed that because i live in Houston and we dont have Summer so much as we have Broil. its not hot like Nevada, its jungle-nut-sweat-humidity heat.

An intake will give you more power than any under drive pulley.
