Has anyone installed a Vortech S/C along with Steeda UDP's?
Due to poor planning on my part, I am now stuck with a bit of a dilemma. I've recently grown VERY interested in purchasing a Vortech V-3 HO system, but as my sig reads, I have Steeda underdrive pulleys on. From what I've read, if I put the supercharger on, it will output less boost due to the pulleys "underdriving" the charger. I honestly don't want to get rid of the UDP's. It would be hard enough to have to part with the CAI as it is.
Is it possible to run a smaller Vortech pulley to compensate for the UDP's less rotational speed? How hard would it be to get it tuned? Has any of the "mainstream" tuners (bama, brenspeed, vmp, etc) been faced with this situation before?
Thanks.

You're gonna spend crazy money on a supercharger and cripple it out of the box? Unless you want 10% less power out of your supercharger, you need to go back to your stock pulleys. I'm having a hard time figuring out why you wouldn't.

Go easy on me, guys. I just figured maybe it would be possible to have the best of both worlds. Have the benefits of less accessory drag from the UDP's and still have the blower put down 7-9 PSI of boost with a smaller pulley.
Like I said, I wasn't planning on going F/I in the first place but ever since I've added the UDP's, Charge Plates, SLP's, etc, I've felt what this car is capable of. I have tasted the power, and now I want more! You all know how it goes...

But underdrive pulleys only provide less parasitic drag on a stock system. Add the supercharger and all bets are off because you change the whole system by adding in another pulley and several inches of length to the belt.
Furthermore, the S/C pulleys are sized to make the impeller spin at certain RPMs assuming the stock crank and accessory pulleys... change that and you may cause the impeller to spin more than you want it to.
It's like getting 20" wheels and wanting to keep your 18" tires.

for example a local guy who has a magnacharger and ive run all most a second faster than him in the 1/4 mile lol

Lose the UDP's...they aren't worth it. When I installed my Kenne Bell I forgot that I had UDP's on my car. When we put her on the dyno to start the tuning - she was only making 2ibs of boost!!! So we figured it out and put stock pullies back on the car. She bumped up to the 8.5 ibs of boost she was supposed to be making....
Trust me - you'll enjoy the power adder a lot more than any CAI or UDP mods you have....no comparison!
I mean...if you have the money and can rebuild your engine with forged internals - that's always good too...but the s/c is probably a cheaper and easier way to get in the FUN ZONE with your car =) Just don't put too much boost to it or you'll break your bottom end and be forced to do a stronger build.
Personally, I went with the s/c and figured I'd enjoy it until it breaks my engine and then I'll rebuild the engine...it's been since August so far, and life has been very good and I can't help but smile every time I drive my s/c'd Mach!!
