Considering a blower ATI vs Vortech? I am debating on getting a blower for either my SS or my WS6. Both have stock shortblocks. Just curious what do you all think is the better kit, with ATI's problems lately and Vortech's know problems in the past.

If you keep the kit stock and don't try and tinker with it to get more boost than its good for, you will be alright with either kit and make good power, ATI might make slightly more and it has twin intercoolers.........
I got greedy with boost, and still have not got the belts to grab, I ditched the 8 rib setup for a COG setup now, waiting for this in the mail and hopefully it works.......
I guess ATI is working on an 8 rib setup for their standard kits........

There's a thread where we discussed this a couple weeks ago. You may want to find and read it for more info.
I have one of each on completely stock internal motors. Both work fine with no problems on moderate boost (8 psi on the ATI kit, 9 psi on the Vortech). I'd have to concede that the ATI twin intercooler set up is much more thermally efficient than Vortech's aftercooler deal. However, both produced similar power.
Key is getting a good tune. If you want the car to be relatively hassle-free and nearly as low maintenance as a stock car, then don't monkey with the boost. I don't want to say that any of my cars are "fast enough" because we all know there is no such thing.
However, both of them are pretty quick and bring a smile to my face everytime they go into boost.

Just curious.One primary, one backup, and.... ???
Seems like both kits work well out of the box.
Seems like the ATI kit is a bit more liked at the beginning because it's easier to install.
But it seems like the ATI kits have more problems when you try to push them to say 12psi. The problem is not the head unit but the tensioner and the brackets.

The vortec kit won`t fit on the SS without hood modifications. I`d do the ati kit with the front mount cooler on the SS. Becase you get more airflow from the nose being open on the SS vs the WS6. more airflow = cooler IATs and coolant temps.

I plan to get the 3 1/2 inch VFN SS hood. I will definetly be doing some research, but I think the Vortech may be the way I might go, at least until ATI gets their problems fixed.

Longer answer: The '99 is my daily driver and perhaps a road race car if I find the time. I bought the '01 SS as a perfect weather cruiser and show car. Then the '02 came along, already built to the hilt, and for a steal... so I couldn't resist. The SS is not ready for the track, nowhere near, but the '02 with the ATI has everything: suspension, 12-bolt, clutch, etc. So, I figured here's a killer blower car that's complete. I can run it at the track and show it if I want to. The LT1 car ('94) is my bracket racer with a built 4L60E. So, as you can see, each has a different role.

Yes he is insane
But it's fun to watch his car up the track. Whens the LT1 going to put the smack down Todd???
