Here's a good read on twin screw vs. roots type that explains the differences: http://www.kennebell.net/techinfo/ge...romcatalog.pdf

 

Wow, that RMS unit looks awesome. I like that they stuck with the reliability of a belt-driven water pump.

 

Hi Tony..

When I set out to find the best SC available on the market for the Mini application, all the roads led to the Autorotor twinscrew range of products.

It certainly helped that I spoke Swedish as the company is out of Sweden.

But first and foremost packaging was a concern, allowing only a very small
SC to fit in the stock location.

Will it produce 275hp....Yes, according to the Autorotor engineering papers
it will flow enough to reach 300hp or perhaps even more depending on
what has been done to the engine. How is that possible you ask, this unit
will out flow the Eaton charger by at least 30% and run much cooler allowing
better fill of the cylinders.

We do have some other upgrades in the pipe line that will substantially
enhance power delivery and reliability making this kit an exciting option.

The " Air Gain System" will be part of the new SC system, giving you a path
of building a complete Mini system.

And as always feel free to call me to discuss any of our current or
future products.... :smile:

62Lincoln, thanks for that very informative link! The temp delta is awesome with the twinscrew. I also now see why it flows better .

Peter, thanks for addressing my questions. This seems like it will be the most efficient and reliable way to achieve some serious gains .

I don't think Randy has any Pulley Parties for a while... let's get busy on this baby!

 

I can't wait. I've talking about this with my friend who developed one for his '82 VW Cabby for about a year now. The RMS looks promising.

Peter and Randy,
Please make one that is reliable. What is the life expectancy of the electric water pump? Where are you going to put a another coolant/water tank for the Air to Water?

 

Everyone should read this:

any updates on viability?

 

Maybe it's way too early to ask, but is there a ballpark estimate on price?
I'm giving some thought to the turbo upgrade but I would prefer a bigger, badder blower due to simplicity.

 

any updates?

 

Thanks for the link, Andy. Mine came in the mail yesterday and I'll spend the holidays reading it . If I can stay awake, that is...

Marty

 

If you fall asleep, it will be from the turkey, not from the reading.

 

Any updates?

 

Yeah, still plenty of turkey left....

Turkey sandwiches, Turkey soup, Turkey & gravy....

 

Wow, the twinscrew seems a MUCH better alternative to the twincharge system... not only does it not raise intake temps, it LOWERS them. I have a question though, I know M7 plans on selling this unit but who manufactures it?

 

Well, we will be manufacturing the kit, and Autorotor will be making the blower.


The belt driven kit on the RMS kit requires the removal of the AC. They also make a kit with the electric water pump. We are already working together to evaluate this kit - I should have one in the States by January (the funding is the only hold up, so buy more parts from Webb Motorsports!).

Peter and I are already done with the mounting, and need to work on the belt tensioner and manifold. This unit will be more involved than the kit from RMS, but will also allow more power due to the additional redesigns.

Ballpark pricing - on the RMS kit, $4900, not including the intercooler. If our dollar was stronger, it could be cheaper.

Anyone wanna invest in a research project??

Randy

 

The WebbMotorsport/M7 blower will not be the RMS one, thus will not require the removal of the AC?

Also, should it be around the same $$ as the RMS kit, so the $4900, which is still a hell of a lot less than the SPI Twincharge.

Sounds like a great plan, great deal, great everything.

Looking forward to this very much!

 

any other way to play this on a mac?

 

Just to clarify, Webb Motorsports is involved in the import of the RMS kit, and it is available with or without the electric water pump. Wiht the electric pump, the kit can use the AC - the belt driven water pump requires the removal of the AC (and then only the compressor).


Webb Motorsports is also involved in the parallel development of two other systems - and Autorotor Supercharger replacement, and a turbo that replaces the supercharger. The Autorotor is the kit being developed with M7, and will be much more extensive when compared to the RMS kit - it will be a new blower, intercooler and intake manifold. Obviously, that will increase the cost a bit.

So, there are three systems Webb Motorsports is involved in:

Webb Motorsports Turbo (for the S - replaces the blower)
RMS Autorotor Supercharger
M7/Webb Motorsports Autorotor System

The RMS system is up and running, I just need the funds to get it here and make sure there are no issues with it. The other two are in development and both should be ready by the first quarter of '05.

Hope that helps!
Randy

 

Thanks for that clarification!

Thanks Randy, that's what I was looking for. Any idea on how much more the M7 Joint venture will run? Perhaps $5800 - $6500?

I'm not a fan of losing the AC (especially with the auto-AC option!)

When should we be seeing the fruits of your labor?

 

Well, the more parts I sell, the faster it gets done - hint, hint.


The M7 kit is going hardcore on development when I fly out there right after the first of the year. I was going to go this week, but Peter and I both have too much going on to dedicate the solid two weeks or so it will take to get everything straightened out. After that, it may take another two weeks for us to get prototype pieces, then another month or so of testing. I'm hoping to have something by the end of February if all goes well.

Cost will depend greatly on production costs and unit costs. To early to tell at this point. I don't want to be priced out of the market though.

The bargain will be the RMS kit, and it allows the use of any intercooler - including stock. It can also be purchased with the electric water pump which allows the use of the AC.

Hope that helps!
Randy

 

bump.

 

What is the displacement of the new Autorotor unit? Will it remain 45ci or will it be larger?
