im guessing people have thought about geting a pro charger or any (cintrifical sp*) blower i did a seach and didnt find any thing some one with money should try it they do wonders for v8s you would have to make a custome bracet though but you could easaly mount it replacing the ac

also alluminum rotors would it work??

and aluminum housings with steal rotor housings or aluminum rotor housings with steal inserts (im sure it could work some how

but even just aluminum rotors i would think would add about 20-30 hp to the wheels???

i dont know im just borred and wanted to know if any won thought about it

and i know i cant spell

aluminum rotors wont add that much, but will reduce engine wear at high rpms, but probably give slightly worse idle due to less rotational inertia.

huh yeha i dont really know but i was just woindering

rs_1101

the answer is yes. alot of companies produce aluminum rotors and housings,, housings for weight savings and durability.

there was a centrifical kit mad for the fc for a while i think it was by nelson? but didn't sell very well. I've often wondered the same thing i know it would work and be fairly easy to and by easy i mean easy for a custom supercharger aplication. buddy just set the record with a procharger on a civic si with a 13.1 1/4 with just the bolt on 9 psi kit.

Probably not. Once made strong enough they'd probably weigh the same, and the oil capacity in the rotors would be greatly reduced. Besides, then you'd have to worry about aluminum's (much) higher rate of expansion in comparison to iron.

Rotor housings already *are* aluminum with steel inserts.

By what mechanism?

Seriously, man, put down the crack pipe...

Atkins makes 3 different sized supercharger kits the last time I counted. The 12" looks like a parasytic twin it is so big
When I build my rotary T-bucket I want to have one of the smaller ones on it just because they look so bad ***. As light as a roadster is it is not like you need the much power anyway.

atkins used screw type roots supercharger like found on a thunderbird sc, not centrifical *sp*

Scalliwag

My mistake, by the time I got to the latter posts I forgot he was specifying centrifugal.
Still imagine this sitting in a '23 T-bucket with a carbon fiber overlaid fiberglass body with only a clearcoat to show off the CF

totallimmortal

wow is that a 3 rotor? looks like rb 3 rotor distributor. what kind of car is that in anyway?

Scalliwag

That is Mazdatrix car http://www.mazdatrix.com/dragcar.htm

i had know idea the fotor housings were aluminum with steal housings

Perhaps you should learn about how things already are, and the reasons why they are like that, before dreaming of ways to make them better.

Saves a lot of time.

Rotor housings are made from aluminum alloy but have a steel sleeve Mazda refers to as a "SIP" that the apex seal rides against. The SIP has a hard chrome plating to withstand wear.
The side plates are cast iron but aluminum ones are available from Racing beat for about $1200 each (yes that would be about $3600 for the 3 plates )
Since rotors are part of the centrifugal mass there is a balance as to just how light you would want them. Part of that is the type of driving they would be used for. But that is a whole other topic.

Thats's weird, their car was a 20B NA + Nitrous Oxide, are you sure that is Mazdatrix car?

I guess it is, since the pics at the bottom looks exactly the same, but without the charger

If you go to their website there is a video of their 20B with a Roots blower on it, running on the dyno.
