Im sorry, I lied..... he just has a "Modified exhaust and cooled induction system"


lmao
Hey it's not a lie! The methanol injection cools down teh air in the intake. The only reason I have slightly more HP than a stock Mustang is because I'm getting colder air into the cylinders. It's not much different than a CAI really. That's my story and I'm sticking to it.

I've got the MAC u/d pulleys, but I left the alt. pulley off. You can feel the difference, they're probably one of the better bolt ons.

well by the sound of things he want goin to put boost to the car anway, so in that circumstance, i would have to say it is, but like u said if u have a sc than they arent worth it.

ud pullies are always worth it, dont let anyone say different. they are like 90 bucks at most and guarentee 15 hp. thats pretty good. u will feel them too.
I must disagree...they're not always worth it. It depends on your setuop and what you plan on doing. They were great for me until i got my supercharger. With the UD pulley kit, I was pushing 6 - 7 PSI. As soon as I took tehm off and replaced the stock pullies, 10 PSI.

Less RPMs on the crank means less RPMs on a centri S/C. Sure, you gain 15HP from the pullies, but you lose 35 - 45 from the loss in boost.

I definitely love UD pulleys though. I had them on my car until i was finally forced to remove them..about a week or so after I had the S/C on

If you just placed the order, call them up and cancel the cat-back and tell them you want dumps. Where did you order the stuff from?
