Turbo or supercharger
Imagine, Super II's..... I just feel a turbocharger is more efficent becasue your basically just using wasted exhaust gasses. I have never driven a supercharged car. I have read the arguments over which is better, for whatever reason, etc. I'm jut glad my TII is a hell of a lot faster than my old N/A.

David Grimes, I have not had a blown rotary, so's ya know. I proposed the idea about two years ago (maybe three) here of using an Eaton M90 on my stockport 12a. (Look it up. Lotsa good info.)
Here's what I have learned...
I have yet to slap that M90 on my little puppy, but whenever this old BS rears it's ugly head, I'm amazed at the knowitalls that wanna compare apples to oranges.
First of all, the Atkins blower...I met Dan. I like him, he's a great kid and not a malicious bone in his body. But his ole man bought the Camden from MazdaTrix, he didn't make it himself, and so I have no problem saying that that **** is older than Direct Freak!
Two lobes, straight, and I'm not even sure if there's a teflon apex seal. It requires plumbing for an oil line, utilizes no bypass valving and is not port-conducive to breathing in cooled charge.
The Eaton M90 is a tri-lobed helical rotor design and port-timed to get rid of that "Fuppp-Fuppp-Fuppp-Fuppp" pulsation, is lubrication-resevoired with a plug and can be orientated at any angle, and utilizes a bypass valve that while you're cruising is said by Eaton to leave the blower using 3 HP (THAT'S T H R E E ) to spin during cruising.
And Eaton guarantees, as an OEM part, their supercharger series for O N E H U N D R E D T H O U S A N D miles!
I only figured it was fair to mention that not all SCs are made equal, while turbos are pretty much one design.
2ndGenV8RX-7(Kenishi please forgive me for typing that) mentioned the Lysolm...the Eaton M series is about as close to a screw-type as most of our wallets will allow for.
Ehhh. Family takes priority, ya know how it is. Hopefully someday I'll be able to start my project. The plan is to make a kit with all the brackets and **** and sell it to you guys. Then you just need a blower and intercooler. Trying to make it so you can all boost your rotaries for UNDER $1500...12-15 psi max, and NO CHANGING PULLIES!!!
If it all works out, I'll have a manual over-ride for the by-pass valve that gets set into the dash.
"Dial-a-boost"
You people think I'm kidding.

The eaton M90 is for fuel injected vehicles correct? Most of us on the first gen pages arent fuel injected so the m90 isnt that feasable. If im wrong, then scratch everything written here. Ive looked at that supercharger before and wished it was for a carb setup, would be an easy ordeal.

The Camden S\C is set up for both EFI or carb...

The M-(0 is for anything yer little mind dreams up!
Dan, I thought that Code Blue's car was very nice. And her hubby is a psycho!
But, I plan to multiply that power output from a streetported 12a by a factor of two.

Dan, he had mentioned that you can get one on ebay for like 300$. The ones on ebay are normally used from newer cars,thus not for carb set ups. Yours on the other hand, yes they are for carb if you like, but cost alot more than 300$. I think the value of your supercharger is fair, but not for everyone. If you supercharge anything, normally cost you 2-4000$ depending on what you buy used and new.

yea They're going for like 150 now and you can use a M90 on anything you want. I've seen them on FI and carbed mustangs. And I've seen awesome reliable setups witha used M90 for less than $800...
