I was thinking of getting a blower for my 93 GT in the future, and was just wondering...what's the biggest out that's still practical for daily driving? I was thinking either a D1SC or a Vortech G or YSi trim...any opinions?
 
Well, I'd be putting it on a rebuilt 302 at first, then I have plans to swap to a 351. I'd want to make somewhere in the regions of around 450-500 at the wheels, and still maintain that driveability I desire...and I thought the KB for the 5.0 didn't make much power?

Edit: I don't really wanna go the turbo route, as I just spent a hella lot of money on my exhaust...and me being a highschool student...I don't really have the money to just throw around.
 
For a centrifugal, I don't see any reason whatsoever to install anything larger than an S trim or D1SC. Both are fully capable of splitting the stock block right now the middle. Why install something larger?

Larger blower = more parasitic loss/rotational weight

If you're not going to put a blower into it's optimum efficiency range regularly then it's a bit of a waste.

Out of the two blowers you mentioned, my vote would be for the ATI. Air to Air intercoolers are sweet for a DD streeter. My over all choice for a street blower would of course be the 2.2L KB. Flowzilla inlet, if you don't have emissions concerns.
 
The D-1 all the way. Its capable of 32 lbs of boost, sounds mean, and has a longer warranty than a Vortech. The D1-SC is self contained so install would be a breeze, and anyone who thinks a self contained D-1wouldnt make power is insane. I ran a D-1 on my 342 and at just 4900 rpms and 12 lbs of boost it put 514 to the wheels with box stock trickflow TW's and an alphabet X cam. If I had a custom cam, AFR 185s, and could rev to 6500, 650 plus at the wheels easy!!!! Trust, you dont need a bigger blower than a D-1. Procharger is the sweet!
 
I'll refer to Dag's knowledge / experience but the Twin Screw shouldn't run out of any steam. The best part about the KB is that the boost is always on 100%. So there is no need to wait for the blower to spool up.... Meaning your leaving the guy next to you in the dust sooner. KB's website talks about shifting around 6,000 RPM but on the street, I can bet that is all you need.
 
www.kennebell.net for the new ones. There are a few on eBay once in a while for less.

A 2.2L Blowzilla with the Flowzilla inlet runs $3699.00 brand new. But don't ask how I know because I won't tell.

Edit: I should add that the KB kits use the stock 6 rib sperentine belt and the outlet temps are typically lower than those on centrifugal style blowers so there isn't a need for an intercooler.
