I have a set of polished aluminum underdrive pullies on the way as of monday, what should i expect from them power wise. I always hear around 10 RWHP but thats kinda much huh? Anyhow are there and trick to putting them on crank pullie etc, and water pump pullie, am i gonna have to buy another belt


thanks for looking

Most don't need a new belt, you other mods will vary the amout of hp you will see. 7 is probably possible with stock engine. One or two of them is 'left handed' which means you turn it the other way than your used to.
 
pullies droped my 1/4 3 tenths (best befor was a 14.6, w/ pullies got a 14.3)at the track. noticed a little gain in power I would rec. them. My belt was fine as far as lenght but I got a new one since it as cracking.
 
I tried just using the crank and water pump pulley and the stock belt wouldn't work. Got the alternator one put on and it fit again. Felt a little power gain, but it was probably the last power mod that I've done in a long time.
 
I gained absolulty nothing with my pullies ASP alumiums. I got 0mph dropped 0 tenths and gained 0rwhp. I dont know how some people get 3 tenths or soemthing. My guess is that the weather was different of they just hit a good run.
 
well i recieved my pullies today, i have one question, which side of the crank pulley goes to the crank, the shallow side or the deep side? just curious????

also i have to get them a polish before they go on so i will at least have one shiny thing under the hood
