Have you talked with Tim Haam from past board sponsor MG Racing.. It seems he had worked on a roots kit. Perhaps he has a source for casting the intake manifold. Also would you have to have a manifold cast or could you just plumb it more like a centrifugal unit or turbo with it going into the intake.
I'm very interested in seeing this take off as companies like jackson racing have dropped the ball. With low end boost and a price equal to the comptech or vortech kit you would give them a run for their money or even put them out.

I have actually talked to Schatten about it. So far, the MG Racing one is kinda vaporware. And it was developed for RHD cars, so they had a lot more room on the intake side.

I have thought about plumbing it, but it won't work. The TB has to be on the intake side, and its almost too much of a hassle rerouting the throttle cable. Plus the supercharger has to be mounted to the engine. I thought about jahwerx's idea. That was actually my original plan, but after talking to some knowledgable people, it won't work.

ya i'm gonna agree if i am correct a screw type turbo would result in low end boost making this car king of cars...well there may be alittle exageration but hey i would BUY. (hint hint marketing opportunity)

Are you guys really interested?

I ll dig into this again, but i was approached about a month ago by a tuner here in so cali that has a totally different design of blower. Apparently it possible to get full boost at 3k. The kicker here is that the higher the RPMs the stronger the system. He explained it to me awhile back but i didnt think anyone would be interested with all these new turbo kits available. I ll have to give him a buzz and see what the real deal is. I ll let you guys know soon

sounds good to me... i was contemplating this idea the other day.. a guy had a roots style charger laying around in his garage and i was looking to see how i could mount it and make it work... looked to indepth for me but hell im down to try whatever

If you do a search on "Roots supercharger" then "Whipple" you will find a lot of information and even a really good scandal involving a board sponsor.

I seems that significant interest was there but for one reason or another the project seemed cursed. I say we exorcise these demons and find out why a kit that would be much better for our car than a centrifugal unit hasn't come to fruition.
Per haps some of the old-timers ( I say that with the utmost respect ) can chime in here!

Because of the size and weight of screw type or roots style blowers, they have to be mounted directly inline with the existing drive belts. This means you have to mount the blower either directly over the exhaust manifold or replace the intake manifold. Replacing the intake manifold means developing a new casting which is NOT cheap. Most privateer's aren't willing to shell out this kind of cash. The other problem with mounting it on the intake side is the difficulty of intercooling. The IC would have to be incorporated as part of the new intake manifold. This manifold is now getting big, and probably won't fit under the hood. Exhaust-side mountings are less problematic, and much easier to intercool. You even get the choice between using an air-to-air or an air-to-water intercooler. Whereas with an intake-side setup you have to use air to water which is less effective at cooling, but gives better throttle response. The only problem with the exhaust-side setup is your blower is now mounted directly over your header, so it can get a little too warm. The blower has internal oil, seals, and bearings which would much rather be cool. Check out how Jackson Racing does their Miata kit for an idea of a what an exhaust-side, RWD, 4 cyl application would look like.

I'd prefer to see an intake side kit. It would be more expensive. But, done properly, it would be super clean with a new intake manifold, and utilize Laminova air-to-water intercoolers. HyTech (an extremely reputable and expensive tuner who may be worth contacting) has been working on a SC kit for Civics and Integras that uses this exact setup. Tuning also becomes a problem with positive displacement (PD) SC's. Because you can go from vacuum to like 8 psi of manifold pressure in a fraction of second, things get complicated. More so than with a centrifugal blower where boost builds slowly and predictably. A standalone ECU will likely be required to get the car to run as well as it did stock. More money.

I would be interested, My only concern would be that I'd need extensive reliability proof / testing done. Even with those results, I would be hesistant about buying the first batch.

But the interest is definitely there.

Alot of people would be interested, how many would actually buy it is another matter.

Alot of people were interested in changing their tach/speed colors, then when a brighter, better solution then the inlays was found not too many people posted because of the cost.
