FI is force induction or for another words, a supercharger or turbocharger. there are all sorts of website that have them. americanmuscle.com, v6mustangstuff.com, again, all sorts of website. and by 25%, i mean the size of the pulley. good luck.

do you think it would be cheaper to have this installed or buy the tool and do it myself? and does anyone have this specific kit?

nm, i just went in to checkers to order a new driver's side mirror, and a harmonic balancer pulling kit was only $16. i think i'll order that kit later today.

Let me know how it works out for you. I was thinking about buying that same kit and i'm curious to see how you like it.

A UDP is an okay mod but me personally, if you're going FI, I wouldn't bother with them. As for me, I'm going supercharged and so the UDP really wouldn't matter for me. It's just a waste of my money. If your not planning to go FI anytime soon, then most definatly, you should get it. Also, I think 42 would be way too large. You'd have to upgrade your alternator, you couldn't have an aftermarket speaker system, etc. A 25 will net you around an extra 10hp and will do enough. Whether getting one or not, or what type, depends all on what you want to do.

RE: underdrive pullies
And what type of pulley did you have on? A 25 or a 42? A 25, you'd be alright but it'd be nice to have some capacitors with your system.Having the pullies does slow down the alternator. A 42,I wouldn't even tryit.And yes, I know if you're going FI, you can't run it. That's why I said I wouldn't bother with it.
