Which UDP's are everyone using? Experience with it? Any battery issues oralternator issues?

I went with the DynoJoe set which are the same as Steeda and pretty much ever other pully set available. I went with the cheapest because they are all manufactured in the same factory but just a have a different name printed on them and what not.

So if you are looking at UDP's I recommend www.dynojoe.com for the best price and yes it is the same performance gain and no you will not need a re-tune(if that is a question you may ask).

i'm also wondering about the battery/alternator problems if any

Steeda is the most popular choice and they are worth 10 rear horsepower. www.brenspeed.com

Also no problems what so ever with my car and I have had them over a year.

You'll be fine, there's only be a few reports of that being a problem but even then people haven't been for sure. I mean unless you are constantly blasting your AC or doing something very unusual even then I think you'll be fine.

my AC blows way too cold to begin with. my dad even joked about it when he rode in my car.

i guess pulleys won't be a problem then

That HP is debatable.
But yeah, no problems here for the last year. Hot/cold, or on the road coarse.

Steeda here, 9hp on dyno.

For what it's worth most of the underdrive pulley kits out there are manufactured by 1 company and then repackaged and sold as several different brands. We sell the Steeda, Granatelli, SLP and Roush brand pulleys.


The Granatelli pulleys are the best buy at this time and on sale for $179.95 with Free Shipping!!

Let us know if there's anything we can help you with. Thanks, Jared
