I currently have a vortech v-2 strim SQ.... Should sell/trade it for a new Kenne Bell Flowzilla or Blowzilla.
trade vortech for kenne bell???

Well, a KB should produce more torque than a Vortech, with equal top end I thought. More down low, the same up top, I'd say it outperforms.
But yea, we can't really give you an accurate answer without more info about your car, your wants etc.

oh thats interesting, i dont have any experience with KB's but a little with vortech's. I had always thought the KB was better on the low end, but the vortech would get more up top.

AFAIK, whipple blowers produce more torque than centrifugal, but I don't know a whole lot about them.

To me, a Kenne Bell is the perfect street supercharger when your car is typically at lower RPM's, where the KB "outperforms" say a Vortech (twin screw vs. centrifugal in general is this way). However, Dyno results and track results don't lie, a Vortech/Paxton/Procharger will typically beat up on a Kenne Bell when you get into higher RPM's where the centrifugal's make their power. You won't see many people who are serious about drag racing only running a Kenne Bell because of this. If your car is a DD or will see the road quite often, you can't beat a Kenne Bell for what it provides. On the other hand, a weekend warrior/full blown drag car would be better suited with a centrifugal blower. That's my .02.

Having had both a Blowzilla and Vortech I will give my .02
Street Fun, Lower boost levels (under 10-12) Mild combo...Blowzilla by far. They work well with very mild cams. Big Torque down low. Done as far as power by 5500-5700. Common 6 rib belt slips badly with higher boost levels. Lots of heat generated at max boost. Does not hot lap and requires a cooldown between runs. Max power levels WILL be lower. Under the curve power is much better.
Street/Strip Drag, Centrif. Softer bottom end but comes on like satan himself was under the hood at higher RPM. They spin much higher, Dedicated belt with 8 Rib or cogs for higher boost. They take better advantage of higher spinning engines.
It comes down to what you want from the car.
I made 450's with the KB at 15#. Exact motor with the Vortech 606 at 17#.
Again for street cars...KB....Dedicated Drag/Strip/Street a Centrif.
This is only my experiences with both.

The car is a daily driver with maybe 18-20 trips to the track each year. I don't road race but i still want to be able to beat LS1's and maybe a base model vette. How much harder on the drivetrain will a KB be. Right now I'm looking at $3600 for the KB where my vortech cost me $2386 from supercharger4less. I want about 350-380rwhp max with a like amount of torque.

Check out my car domain page. Has my build history with the KB and H/C/I I made 385/414 with the KB

I try and put a disclaimer in my posts when I'm not positive of what I'm talking about. I never really have compared centrifugals vs. twin screws as I have never been a big FI guy.

i have a daily driver, and i never go to the track
for a mostly street car, i prefer the k/b because of the instant boost that makes it really fun to mash the gas.
yes, centrifugal blowers can make more power up top, but how often do people wind it up past 4500 on the street?
for me it is the high, flat torque curve that starts the moment you open the throttle that gets me going.
$.02 more for ya

If you are building the combo for a modest power band (shift at 5500 or so) then I say go with a lower gear and a KB. If you want to up your gear and take advantage of high rpm power, shifting more like 6000+ I would go centri. For someone like me who just wants something crazy to drive in town, the KB is perfect and still good for 11's.

I would recommend upgrading the cooling system with anything more than moderate boost levels.
My KB would get pretty hot at the track. It ran hot on the street too, but not to excess.
Safety is all in the tune.
A major disadvantage on the KB is where the air inlet temp is on the 94-95. It measures the temp in the inlet tract....Not in the manifold like the Fox.
This can have an effect on the EEC table that pulls timing against Air Inlet Temp.
Relocating the IAT sensor to the fox location is the best solution.
I was not sucessful making big power with the KB. I didnt want to meth inject to get the timing in at higher boost/rpms.
KB's are great street blowers and can take a car deep into the 11's but if its a track car...go with the centrif.

Keeping my vortech and gonna use the extra money I have right now to put on a set of gt40y heads ($619) plus install and do a gear swap since i have stock 2.73's. Anyone have a set of gt40x heads for around 600-700 used in good condition??

Only thing i was gonna add....if u beat ls1's then u will beat base vettes. They are basically the same ar and im pretty sure that they run just about dead even.
