underdrive crank pulley

[cashmoneyspeed]

Has anyone installed an Unorthodox underdrive crank pulley or simialar? What kind of gains should i expect? would a stock pulley off a probe gt v6 or mx-6 v6 be better ?

[lazzyie]

stock probe/mx6 pulley is the same as ours, udp pullies give like ~5whp, build a cold air intake for like $40 and get the same effect

How long would it take to install an underdrive pulley? would i have problems with my sound system receiving proper voltage?

[lazzyie]

if your really worried about it set your idle to like 900, i belive you have to grind down the p/s housing or something and you need new belts, and a pulley remover, jack up car, pull off tire/splash guard, pull off belts, pull off pulley, put it all back together, couple of hours if you have no idea what you are doing, dont quote me on that, there is a guy on probetalk that sells udps for $135, same specs/alumminum as unorthodox but $60 cheaper, just a thought

You have been very helpful tonight. would you happen to know who it is that is selling them? possibly a link Does anyone know where i could get the larger sixed belt? and how it would affect gas mileage?

[lazzyie]

look in the 2.5 v6 performance forum, his name is mazsly75 i think just email him, the belt sizes are on unorthodox's site and can be bought at autozone<p>[ September 23, 2002: Message edited by: lazzyie ]

Does anyone know cheaper ones to buy? $199 is a bit too much for my taste.

Trust me, $200 for that boost in power and the small amount of time invovled in worth it.

It is, rather, for a couple of hp. And you need to remember you live in a cold country, so your battery needs to be well topped up to start the engine in those winter mornings. If you do a fair amount of low speed town driving, with the alternator running slower than designed.....

Damn, just saw one on ebay yesterday for around $60 USD but it doesn't show up on a search now. I have noticed them starting to appear recently on ebay though for well under 200. Might be worth watching...

True, didn't think about that. So maybe I should stay off it then...

you have to do some grinding to the oil pump housing, its easy to do but you gotta watch out for the crank angle senor and your timing belt

There are some OBX underdrive pulleys on ebay right now for like 60 bucks. Installing shouldnt be that hard if it is a direct bolt on. Autozone will rent you the tool you need to take off the stock pulley for like $11.81usd and then give you the money back when you return it. Hope this helps....

[papa roached]

all of these are of the same design, you WILL need to do some grinding and cutting to make them work
