Default Superchargers ATI vs. Vortech??

Hey everybody!
I have been reading this forum for a while and finally i've saved the dough and can build something worth talking about with you guys. I've got a 1996 firebird LT1. So far I pulled the motor,.30 over, forged Eagle crank, JE blower pistons 8.5-1,H beam rods, splayed end caps balanced & blueprinted etc. Now I am at the stage of which setup to use. More people use the ATI D1sc but I am leaning towards the T-trim Vortech setup. I am looking primarily pure power. Looks, reliability are all not huge factors for me. I just want speed! (who doesn't). Any input??

I'm one of the few guys here that uses Vortech. I'm running a Vortech T-Trim with Aftercooler and I'm happy with it.

there was a buy back awhile ago who had a FS thread that laid down like 950 hp out of a vortech LT4 but it was absolutely ridiculous like 23+lbs of boost, so vortech has the potential, but ATI just has swept the market

Procharger for the win, so what if everyone else has one. That should tell you something.

I'm running an F1A on my 355 so i'll vote for ATI even though I don't have any first hand experience with Vortech.

Wow, ATI it is! So what are you guys running for heads? I had the stock ones worked over with larger valves and roller valve-train but i heard they don't flow well. Also what about ignition? Should I leave my stock opti-spark ign sytem and just get a mail order tune for my ECM? Any reco's on a mail order tune?

I'm running an MSD opti with an MSD Digital 7. Works great. As for the tune, forget about the mail order tune. Get it tuned right on the dyno.
