Anyone heard of Allen Superchargers

Speaking from Personal Experience....

I've got an Allen kit on my car and I like it a lot. $6,500 installed for an intercooled Positive Displacement Supercharger is a really good price. You’ll pay nearly that much for a Kenne Bell, Saleen or Roush without the install fee. Yes, some blowers will make more power, but the drivability with this kit is excellent. And yes, the Centrifugals are cheaper which makes them quite attractive, but on a street car running the stock bottom end, they don't make anywhere near the torque throughout the power band, which really bodes well for the Positive Displacement car. My car runs low-13's to high-12's at the track at over 4,200lbs (with driver) with a conservative tune making 343rwhp/389lbs ft/tq running through an automatic transmission and independent rear end. And I've got the REV I kit. Your '01 will be utilizing the REV II manifold, which is better still. Expect to put out about 370RWHP and like amounts of torque with the 9psi kit, which is pretty much on par with any of the other entry levels kits.

Here are a couple of video’s of my car at the track and on the dyno. The blower whine at full throttle alone is more than enough reason to by one.



Pay no attention to my transmission issues going down the track. I've since had the problem fixed.

How'd he steal that? I checked in on one from The Mustang Shop in Alberta and they wanted 6,500 just for the kit alone plus delivery....and that was only paying the one tax?!? If he can get the intercooled version of the 2.1L kit for $6,000 installed, then I suggest he buy it. As long as he doesn't have to deal with Kenne Bell directly in order to do so. I'd pay an extra thousand dollars just to deal with someone else if that were the case. And 435rwhp on a stock long block is possible, but I’m betting it wasn’t with just the kit alone. He’s gonna have bolt ons and most likely additional boost to see that kind of power.....maybe a little race gas in the tank too? Otherwise he’s making about 50rwhp more than everyone else I’ve ever seen with the same set up.

I'm not sure what you mean by "seems like a better kit"? The Allen is as complete and high quality kit as the Kenne Bell or any other that I've seen. It utilizes a Gen III (with an optional GEN V) Eaton supercharger, which is by far the most durable of any Supercharger on the market to date. And the best part about it was the customer service I got from Scott. I didn't have to wait for hours for a phone call to be returned.....if the phone was answered at all (unlike Kenne Bell when I made the attempt at inquiring about their product). Like I said, the Allen may not make as much power as some of the other blowers do, but it's certainly every bit as high quality.

Hey Alan, nice to see you here. Funny you should show up in this thread, the vids above I posted were actually at taken at the Shootout in Xenia where I met you this past summer. We actually smoked a couple of cigars together in line up at the end of the track event on Sunday, on the way out. How's the Baby doing?

It's a shame to hear that Allen went out of business again. The built a great product, but were never much for marketing. I like the new kits above....with the option of an Eaton TVS series blowers too. Now we're talking. Move over Kenne Bell and Whipple, there's a new Sheriff in town.

You're not going to find any Turbo system that doesn't result in some measure of Turbo lag. I don't care how well they say it's been engineered or how small the turbo(s) are. It's unavoidable! They're great for making ultimate power and strip cars, but will never provide you with perfect drivability on a street car. Their power band is too peaky and too narrow for them to provide perfect street manners. There's a trade off to all that power and turbo lag is it!

Cetrifugals don't have that lag and do provide a great bang for the buck power, but they don't start seeing much of it till the 3,000-3,500RPM range. There's no lag mind you, but there's no additional low end torque to be made either. This can be countered some with weight removal and gear changes, but it will add to the cost some and affect over all fuel mileage as a result. The rush at the mid range and top end is kinda nice though and the price is right.

If you want torque down low that'll throw you in your seat on command with a touch of the throttle, with no need for gear changes, or weight reduction to overcome RPM deficiencies or turbo lag, there's no other forced induction set up that will do it other than one of the popular Positive Displacement kits available. If the Allen isn't your style, then I'd suggest looking into the Kenne Bell (just don't buy direct from Kenne Bell if you get it), the Torktec system described above or one of the kits from Saleen, or Roush. They’ll start making power just about right off idle in most cases and can be delivered as smooth or as violent as your right foot will allow it to. No waiting for engine RPM, or exhaust pressure to ramp up….it’s just throw and go! The do start to level out at the top (yes, even twin screws) and won’t provide the top end rush that a turbo or centrifugal unit will, but that’s not to say they fall on their face at the top end. They will continue to make power to red line, just not to the extent of a blower that designed to meet their efficiency rating at the top end of the tach like a Centrifugal.
