Millenia/Lysholm Questions?
Hey, anyone tried using one on a rotary? Does anyone know the displacement per rev? I'm thinking about trying something like this out...

I bought one to use once 5-6 years ago, but never did use it as didn't really have a problem w/ turbo lag like I thought I might.
88IntegraLS bought it and put it in a car but never got it tuned. I think he spun a front bearing as the last thing I remember him writing about it was that it made a clicking sound as he revved the car- and then he was all about putting a V8 in there.
That is something to consider with the rotary, they cannot tolerate much load on the front of the e-shaft. I would consider a Gilmer drive if I was to SC one or a centrifugal SC as they require much less power to drive.
I thought the Millenia SC would fit up nice to the 13B as it was out of a high boosting 2.3l Miller cycle engine.
The SC is quite long, so the inlet gets cramped at the firewall. It should be placed away from exhaust heat as it will cause them to seize. So, on top of the engine or over at the spark plug side?

the millenia has a very efficient small engine that makes what 200 or so FWHP supercharged. That supercharger is going to be way out of its efficiency range making 200 FWHP on a 13B, which would take at least 20% more air and fuel to make the same power.

The stock TII turbo compressor is outside its efficiency range over 5,000rpm at stock 5.5 psi boost, but it works well enough above that rpm and boost anyways.
We have a supercharged 12A at auto-x that uses the TINY roots blower off a toyota minivan? It only makes ~250 at the wheels, but the response is phenomenal and it has proven reliable as far as I can tell (always shows up).
Same could be said of a stock TII at 250RWHP.
Probably same said of Millenia S SC at 250RWHP.
Bigger would be better, but personal experience tells me it is hard to argue with cheap and effective when it beats you at the track.

I have a hard time believing that a 12A with a previa supercharger would make 250 WHP.
The boost has got to be falling off to near zero by the time it gets to red line.
I think a stock turbo 2 turbo would be a better choice than either of the superchargers, and if you call 250 WHP effective then it can be effective.

Perhaps it will be outside of its efficiency range, however it may work well and still be more efficient than a roots blower.

It sounds to me like it could be a very good alternative!

Sure I will bring a notebook next weekend. I remember it made 180 all motor and 250 with the SC, but I could be remembering wrong and it is from a motor dyno (it was dynoed out of area).
Amazingly, it pulls hard all the way through its rev range. I am guessing it is overspun and covering with 116 octane.

I finally made it out to the Auto-x this weekend and spoke to the owner of the car with the 12A motor with a Previa supercharger on it.
It has a street port and made 240 hp on an engine dyno with boost dropping off to 3psi on the top end. He is running the supercharger backwards to make it work on the rotary.
