Underdrive pullies

[mytight95]

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.

I needed a new belt when i put mine on....

Didn't feel much change in HP though..

 

[mytight95]

well i will post my sig, wonder what i could gain. i have a belt that is too long now, wonder if the pullies will take up the slack

Well I'm guessing if your belt is too long now it definately won't fit with the UD's. I needed a smaller belt...

i needed no new belt, when my car was stock it was one of the first mods i did.

I fealt a nice difference with the stock and auto, woke up the 2:73's at the time.

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.

 

[mytight95]

cool so many differences, guess i will just have to see when they get here


thanks again guys

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 cant wait to install my march underdrive pulleys. what bolts did you guys use? stock ones?

on the March pulleys site they have an article from 5.0 Magazine saying they got a gain of 15 hp at the wheels

not only do they perform, they look good too.

Stock bolts are all un need, I doubt you'll get as much as fifteen.

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.

 

[mytight95]

well i wont' go before and after the pullies so i wont know what i gained but hopefully i can tell with just the SOTP meter


lol

I dunno bout all that. Maybe a little leak on the front end....

Maybe i just needed a new belt with the UD's cuz I had previously done the smog delete. I dunno, stupid BBK's.

 

[mytight95]

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

[blksn955.o]

The crank pully is flat? maybe you got some 87-93 ones instead by mistake?.

 

[mytight95]

no i got them on, they are the 94-5 pullies because everything lines up like it is supposed to do..... They look nice i took pictures of them, will post later
