I've gotten the W100AX dimensions from Whipple's casting company, so I can start building the adapters required to bolt the W100AX (1.6L Whipple twinscrew) to the LSJ motor.

I don't think I need to go into the details of the Whipple-designed supercharger system. The new W100AX uses new rotors completely designed by Whipple. According to Whipple, the W100AX is in the neighborhood of 81% maximum efficiency.

Why a Whipple vs the TVS? Well, for one, I feel bad for Harrop. Without a test bed of their own, they are getting mired down waiting on words and results from across the seas (over here in the US of A). The TVS is a great supercharger (1.32L blower) vs the stock Generation 5 M62 (1.0L blower), but I feel the Whipple is the end-all be-all of Supercharged LSJ power. Considering I bought my wife an Ion Redline, I don't have that problem - I'll be doing testing of my own all along

Now, I'm sure someone's going to start spewing rhetoric about a turbocharger. Please understand, some of us simply want to stay supercharged, instead of going turbo. The Whipple setup will allow us to play very favorably with the turbo guys Whipple superchargers are some of the most efficient high speed, high pressure superchargers you can get your hands on.

So let's get down to business, what the hell are we talking here?

I'd like to see us, the LSJ community, put in an order for 10-15 W100AX. Now, please understand, the W100AX is NOT yet 100% in production. The rotors have yet to be built This is a project that will be a couple of months in the making, but if we put our money where our mouths are, we'll convince Whipple we are serious about this.

The plan is simple. I've got the dimensions, so I don't need the real supercharger sitting in front of me, just yet. I've got vast experience designing, prototyping, and building parts on various cars, so what I'll do is this:

1) Design the necessary adapter plates to bolt the W100AX to the stock LSJ motor. I intend this to bolt up 100% in the stock location.

2) Start a group buy on the Superchargers + kits. Once we get the minimum order required by Whipple, I have no problem selling the brackets alone, if someone wants to order a supercharger later down the line - but please understand, the first order of business is getting the W100AX into production! I'd like to see us do the snout, supercharger, plates, and utilize the stock bypass valve, for ~$2000.

3) Ok, so you've got a Whipple bolted up. Guess what? Stock fueling/tune won't cut it. So the second part of this two-pronged plans involves a group buy on 60# injectors, harness, and ECU reflash. I'm aiming for $400 on this side of things.

I think a complete kit out the door, WITH fueling and tuning, for ~$2500 would be a great deal for these cars. First though, I want to know how much interest there actually is, and who would be willing to throw down and go through with this?

My next set of calculations is computing the airflow with a 3.2" pulley on the W100AX (still working on getting estimated flow numbers from Whipple's engineers) - I'd include a 3.1" pulley in the kit, so that you can use the stock belt with no problems.

Those of you on the Redline forums have probably seen the work I've started on this as it is.

Also, is there anyone here in the Central Florida region? I understand the Cobalt SS has less clearance around the hood - which means I'd need a test subject once the W100AXs go into production

 

You have a of ambition for this project.

Good luck!

If you can get 10-15 to commit what would be the initial start up investment from each person?

1.6 might be too small for an LS3 but subscribed for good stuff

 

wow. A buddy and I were actually discussing about Whipple making something for the LSJ

i hope it works out.

 

LS3?! what?!

 

Initial investment? Well, the more the better. The largest single part of this entire project is the supercharger itself.

Whipple has already stated that they will not spend their resources to make an LSJ kit - we aren't a big enough market.

The while, however, supply me with Superchargers if I get enough people in on it

I need to know how much actual interest there is in this, however.

 

hmm.. how much "initial investment" ?? lol

 

That'll depend. Can we get this started with say $500-$1000 per? That's completely up to Whipple.

First, I need to show them that there is interest (that we aren't wasting their time)

Then, I need to build the adapter sets. Once the prototype of that is complete, we go to Whipple and tell them we want this, and we want this now.

That will require commited buy-ins. I think the best bet would be an LSJ-wide group buy. 10-15 would be a good start, but if I could call them with a 25-30 supercharger order (I'm looking at you, LSJ shops) that would be fantastic!

 

Im interested if its not a flop

 

hasn't this whipple stuff been tried to start up before and there wasn't much interest because of the turbo's from hahn etc, twin screw (which failed and might come back)..and now the TVS?

 

that's what i'm worried about too.. Although i love the idea, i would like to see some type of forward progress before i invested in something like this.

 

IIRC this has been tried before. A company even took customers money, $1,500 from 5 people I think? I am trying to think what happened to that...

TAG - Rebel anyone?

Waste of time.

 

I'm very interested in something like this

 

Another awesome idea that I really hope works out however I have my doubts on both vendor support as well as buy-in support

 

what you didnt see my build thread i swapped motors and went RWD.

/spam

 

i think when it comes to this stuff...someone just needs to bite the bullet and do the whole thing themselves to show it can be done in the first place. then start making offers like this

 

Very interesting... Id like to see it happen but doubt their will be anybody jump on board

 

That's what I'm doing - but I can't convince Whipple to build just one supercharger, for one person Hence why I'm trying to put this out to the entire community.

As for other twinscrews - those weren't Whipples. Had someone done this with a Kenne Bell (the only other supercharger in Whipple's league, in my opinion) then yes, I would agree.

350-375whp should be no problem for a 1.6L Whipple. More if you really pushed it

 

MK jr had a dream once

he was then assassinated.

take it for what it is worth.

whatever makes YOU happy. do it

375whp on a stock head and cams won't happen on a blower car. same rules apply as a roots style

 

And area makes another smartass yet very funny reply

 

It's would be a nice alternative and I agree with others......someone would need to bite the bullet and buy what is needed, build and prove that it works.
Another thing that concerns me is that someone new comes along with an investment proposition for building superchargers. Given the current economic situation and similar past events on this site I would have a tough time trusting someone with that much cash without some proof or representation from whipple.

 

Understood. I'm going to work on the plates over the weekend, and over the next week or so in my spare time.

The biggest problem (for me, at least) is the fact that the W100AX is not yet in production. And as you just put it - with the economy as it is, Whipple is very hesitant to make the W100AX a reality, without some proof upfront that it would be a good investment on Whipple's part.

We've got to jump that hurdle to get going!

 

I remember when harrop was putting the TVS kit together....... everyone and their brother was going to buy it. The reality is , we have a handful of guys that are running them now.

 

would it be worth it over a TVS?

from looking at the TVS R1320 map, at 18000RPM it flows a little more than 1450 m^3/hr roughly.

at 18000RPM the W100AX claims to flow 1902 m^3/hour (not sure about this as there is no map available just max numbers on their website)

so theoretically the W100AX can move about 26% more air than the TVS R1320 at the same time generating less heat? please correct me if i'm wrong
