What's your goal with the car?

more power..

If you have no specific goals beyond "more power" then literally any blower will give you more power. Buy the cheapest one from a reputable manufacturer and get their tune.

what do you think about the 8 rib procharger?

People seem to like their procharger setups. Centrifugal setups are pretty easy to install, route, and tune, and they tend to allow you to keep the stock hood. Their power delivery will be "peakier" than a positive displacement unit, but that might also help you hook up at low RPM compared to a positive displacement unit. Make sure whatever tensioner you use is up to the task, and I'd probably recommend you pin the crank pulley. If the crank pulley is original / stock, get the upgraded unit. Some people like underdrive units, probably a 10% underdrive won't lead you wrong, but I personally don't care much.

If this is for relatively mild street use, you should be pretty much set with that. If you're gonna run it hard, you're in for a lot of money in upgrading the rest of the system.

I recommend A&A with vortech blower. As far as 6 vs 8 rib etc.... all depends on how much you actually want to make. Going 8 rib is about $1000 extra up front but gives you the option of more power down the road, etc.

Seriously, Josh and Andy @ A@A are very helpful... give them a call and talk about your goals or desires and they will get you squared away and won't try to sell you crap you don't need.

edit: definitely don't get a underdrive pulley with SC... Overdrive quite possibly depending on goals.

A&A was my pick a little over a year ago. Love it!
