WRONG, THE SMALLEST SC LISTED ON THE WHIPPLE SITE IS A 2.3L

YOU ARE LOOKING AT THE NAME OF THE UNIT, NOT THE SIZE.

If the lysholm charts are out of date then what info are you working off of?

Bill

Whipple makes a 1.3L they used it in kits for the PT cruiser and other small cars.

Why would you want a 1.3L unit anyway?

RyanPerrella

LOOK AT WHIPPLE'S SITE! THEY LIST AE at 80% for a 2.3L rotor. They List 75% for a 5.0L rotor but ive never heard of a 5.0L rotor, it would be gigantic so take from that what you will.

But the numbers are clear as day. If they are misleading numbers well then thats another story, but 80% is higher then 75% i learned that in like 11th grade

I don't care about a 1.3. You are the one saying they list efficency of a 1.3 their site. They do not. They List a 2.3l, 3.3l and 5.0l models.

They may make a kit for a pt cruiser but I don't care about that.

I want to see charts for all positive displacement superchargers from 1.7l to 2.5l as those would be best for a 928.

Ryan, I'm sorry but you are not providing good or even acurate information.

RyanPerrella

LOOK AT THE SITE

you want between 1.7 and 2.5, ok well they list the 2.3L unit (which is what i would use on my 5.0L) and it clearly says AE is 80%!

Game over!

We did briefly note the new blower in a ZR-1 thread. We don't need to get hung up about Gen 4 or 5 or whatever it is... It's new and a greatly optimized Roots. It looks a lot better than what I have, so I would try it if I could find one at a reasonable price (maybe the boneyard will start to see them soon). New Gen 5 are inexpensive and used ones in good shape are DIRT cheap. The charts and specs argue that the TVS is up there with Autorotor, but I'm not so sure.

Praise the Lord!


Now does anyone have any real information? Links to actual charts of the sizes and types of superchargers mentioned would be appreciated.

IIRC it wont' fit your manifold.

RyanPerrella

The system thats going into the ZR1 has an integral manifold.

So what that tells me is that the housing is cast into the manifold so using one from a crashed ZR1 10 years down the road wont help you. I believe the caddy will use the same manifold. A cast part with the housing integral to the manifold and the rotors and intercooler cores added after machining. This would not be plug and play.

A new unit out of the box may work. If not you could possibly change the manifold you have to accept the new (if different) mounting locations of the new blower.

You got it! I just hope with all the intelligence and hard work up der in dem mountains that DR will be ready to wup one on the 86.5 someday soon. Maybe a SC install for the tech session?
You know I'm a glutten for punishment though - I'm adding a '81 944 to the stable too

ThompsonBill15

Bill,
I doubt we'll see one in the bone yard in the next few years, however they should be available from their sole distributor in the us, magnusson products very soon.

If it won't fit or adapt to a flat pizza box surface, it won't work.

RyanPerrella

you could make anything thats flat fit. IIRC your manifold is pretty flat. So even worst case scenario you make a spacer/adapter to get it to mount.

But you cant use a take off from a ZR1 or CTS-V, those are totally different. Those should bolt onto LS1,2,3 6 and 7's though!

I was looking for the Autorotor charts and found this information on the site of Opcon, the company that manufactures and distributes the Autorotor and Lysholm (brand) twin-screws. It appears that they have closed the US business unit and the site that thye direct to for business after july 1 2007, www.lysholm.se, is not in service. I wonder if they are still selling the autorotors? I'll try emailing them.

Dear Valued Customer:

In December 2005, we began the implementation of a plan to streamline several of the business units within the Opcon AB family. The move of the Opcon Incorporated office to Michigan has been successful and we were able to offset price increases for many of our aftermarket products. Unfortunately, the American automotive business climate continues to deteriorate. In February 2007, the Opcon AB Board of Directors elected to initiate another phase of change resulting in the decision to close Opcon Incorporated effective July 1, 2007.
