UDP

[blcksvt2003]

anyone currently running the 2pc cfm pulley kit on their SVT?

I have had mine on since mid July. No more engine lag when I have my A/C on.

awesome i cant wait for christmas SS new SVT knob, msd ignition, and UDP glad to hear no problems or anything from it, thanks

[ThatOneBigKid]

Not a problem. I got the CFM Short throw and the MSD ignition with 8.5 mm wires. Really woke the car up. Now its like it should have been from factory.

nice im lookin forward to a nice lil install day, gf will be happy too since i will use my ac more in the summer now, probably half the reason she bought the UDP for me

[ThatOneBigKid]

Yea, I love it cause my fiance has my A/C on any time she rides in it during the summer.

I would only do a UDP if I could get a smaller alternator pulley as well so the alternator still spun the same rpm it did before

was also thinking about the same thing! but instead of throwin on a dif pulley i would just go with a higher output alternator. we'll see how she runs with the UDP first tho

I have an underdrive pulley on my alternator on my Contour. It actually helps the alternator last longer since it's not spinning as fast. Unless you have a big sound system or something else that draws a lot of electricity I don't think I'd worry about it.

I took my UDP off because it really affects the performance of the A/C around town, I honestly didn't notice a huge power difference either.

please explain "affects performance of a/c" just lookin for a lil more info before i throw it on

It may slow down the ac pulley thereby diminishing the effectiveness of the ac.(may not blow as cold). But it also may give a minor boost in mpg and will make your dyno chart look a little better.

i can deal with not as cold...gf might be upset haha ,but at least i'll be using it for a change

[focinite]

just a thought, is not the factory pully balanced? what about harmonics?

[bflesher]

Not sure but on my zetec i couldn't tell a difference, but the tranny mount, now that was a difference.
