Ok here's the big news.

I am going to offer the ability to run 2 different twin-screws. You may use either the Whipple 2300 AX or the Autorotor 2.2L. It was easy to make the decision to do this because the blowers have the same bolt paterns so the existing parts will work.

These blowers were designed practically on the same board.

Both are equally efficient but the Autorotor seems to be the choice of the aftermarket tuners. While the charts don't show it, I have heard that the Autorotor is a little more efficient.

For example Kenne Bell uses the Autorotor 2.2 to make an astounding 701RWHP on the Mustang Cobra.

One of the biggest benefits of using the Autorotor 2.2 is the wealth of information generated from the Kenne Bell systems and in the magazines that test them.

My future development will be based on the Autorotor units.

Performance wise it's pretty much a toss up between the 2300 AX and the Autorotor 2.2.

Again, I prefer the Autorotor because the wealth of info behind it thanks to Kenne Bell.

The only reason I didn't go with the Autorotor in the begining is that they were only available in the US through Kenne Bell. My understanding is that KB will hardly/will not sell them outside his kits. They will soon be fully marketed in the US.

I have the opportunity to get up to 10 of the Autorotor 2.2 now from the entity that will be marketing/retailing them.

For up to 6 buyers the price will be $1825. (plus shipping to you) MSRP is about $2025

For 6 to 10 buyers the price is $1725. (plus shipping to you)

These prices include the drive and a pulley But there may be Tax.

I have to buy all these at once via COD all at once to get the best price.

If you want one for any purpose you are free to join in.

I will be using the Autorotor 2.2 on the 16v systems (as well as low cost OEM type Eaton)

The Whipple 2300AX will be still available from www.superchargers4less.com for around $1980 for the blower, drive and pulley. But I suggest the Autorotor as that is what I will be working around.

Here are the terms.

Because I will be buying these COD, if you have not already paid for your groupo or put down a deposit you will need to pay me up front for the Autorotor. If you have already paid me for the groupo and want a unit you will need to pay me for the Autorotor within two weeks of when I recieve them. I should recieve them in just over a week.

Since PM boxes fill up so quickly please e-mail me at andy@928supermodel.com

These parts are compatible with which models?

Tony

The way i understand it is that the Autorotors will bolt up to the manifold made for the Whipple. Im not sure about the eaton but i assume it is a very differnt bolt pattern.


Im sure andy will chime in.

GoRideSno

Don,
The Whipple 2300 AX and the Autorotor 2.2 twin-screw superchargers are compatable with the system that I make for the 32v cars ('85+)

You can read more about the systems at http://www.928supermodel.com/32twinscrew.html and http://www.928supermodel.com/32jaguar.html.

As Andy mentioned there is a tremendous source of info on this model SC from the Mustang crowd. Heres a pretty good article with dyno charts at diff. levels of boost...intake charge temps etc etc. Granted its a FORD , but when you put out over 500hp on a 4.6 two valve, there is something to be learned im sure!

GoRideSno

Wer'e up to 5 now.


Tony that is a great article. One thing worth mentioning is that they use the 1.7 l Autorotor. On around 8psi non-intercooled w/ race gas on the Mustang GT they make 386rwhp. They put on an intercooler and get it up to 15psi and get it up to 511rwhp. All from a 4.6l 2V Ford motor. I wonder what the CR is on the 2002 Mustang GT?

JUST FYI,

$1825 for drive and pulley is about $300 cheaper than my best price on the whipple.

I just confirmed with the source that the Autorotor 2.2 will come with a 1 year 60K mi warranty.

WOW! That's awesome on the warranty.

Nice article Tony, those are definately some impressive numbers.

Click here to see a link to a comparison between the Autorotor 2.2L and the Lysholm 2.3 (whipple 2300AX).
Looks like the Autorotor 2.2 may be a little more efficient than the 2300AX. The Autorotor certianly seems the more durable unit.

Andy- I'm in for the Autorotor, getting excited....!

GoRideSno

I gotcha on the list Chad. I'm real excited too.

This is the last call.

We now have 5. This means the price will be $1825 plus shipping.

If we get 1 more the price will come down to $1725.

Monday I am calling to confirm the Purchase Order and ask that they shipped Monday too. So please let me know ASAP if you want to participate.

PS: I worked 2 pullies into the deal. One for around 6 psi and one for around 8. They aren't hard to get so if anyone wants more later they can come from Kenne Bell.
