This is the Real thing too!! An M90 on your N/A block.

From the 2nd Gen Forum...

 

thats pretty sweet, i want one for the N\A...hmmm

 

I dont think thatll work. You cant put fuel thru an Eaton. The teflon on the lobes will shed off. Someone here on our forum did it. The car ran for like 30 seconds. He needs to make that a dry flow/ blowthru setup.

 

The M-90 doesn't have the teflon.
The M-62 does.

I plan on offering a "Sterling Charger" blowthru kit using an M-90 and intercooler by next year.

 

Is a roots blower really the most efficient option? Generally a roots blower is parked on top of a piston engines intake manifold, not blowing through a pipe. Especially since the rig pictured doesn't really have any curves or funnel shapes to help flow.

Oh well, the point here was for it to be cheap. The guy seems to have done his homework, and did a decent job fabbing it up. Bravo.

 

if you saw or read through, he doesn't put fuel through it, its like a turbo set up

 

i'm sticking with turbo all the way! WOOHOOOOO! but that is a smart guy there.

 

probably a dumb question... how much power would you estimate a S4 low-comp motor and a SC setup like this makes?

 

so now, how do you use the M-90 with a stock carb? Should be easier I would think.....

This is a very interesting concept.

 

Neat, low-buck way of doing things. May have long-term problems, and has lots of room for improvement, but still neat. It's not supposed to be the end-all of performance mods, just a cheap way to more power.

The basic idea would work for a blow-through carb setup too.

 

a fun little toy would be a 12a, m-90, and a sterling carb (he's developing boost-friendly carbs, no?)...

 

Yes, we'll be offering boost prepped Sterling Carbs soon.

Search in this section under "M-90", and "M-62". You'll find where I entertained the very same idea using the Eaton as a cheap alternative to the -back then, hard to find- 7" Camden.
I was planning at first to simply box the carb, but it'll be less work to prep the carb and cap it.

 

Is there going to be a EFI kit anytime?

BTW, if anyone else was as confused as me about superchargers, you should check out this site. Has some pretty interesting TECH articles.

Alright, so now I could either get a sterling for my stock port, stock intake. OR.......a sterling made to go with this M-90 eaton s/c off a t-bird?

please correct me if I'm wrong here.

If so, what would be the difference?

What's the risks of running this s/c on a n/a rotary?

 

Why dont ppl mount the supercharger where the air conditioning used to mount? THe bolts are already in there, plenty of room, and it would be a straight over-engine shot to the carb.

Seems to me that would work well!!

 

i thought the s/c needs to be in between the carb and intake, aren't most hotrods that way. Just one sittin on top of the other?

 

depends on the supercharger...

 

I have always thought that would be the way to do it. Only hard part is the inlet is on the back of the SC.

 

so no in the case of using the m-90?

 

the M90 is made for EFI and can not have fuel put through it. The one by Atkins is made the way you are thinking and works that way.

 

I'm a newblett when it comes to turbo's and superchargers so i've got a question, I know turbo's are driven by exhaust, and super chargers are driven by belts. So, wouldn't the supercharger be much more effecient than turbo's sense superchargers will not have lag (as trubo's do) since it does not have to wait for the exhaust to spool up the the turbine. And to get MORE power out of a supercharger all you need is a smaller gear, correct? when to get more power out of a turbo, you would have to buy a boost controller or somthing of that sort. my question is, why are turbo's so much more popular? And how do they make so much more power? I personally want to supercharge my car, but since turbo's are alot more popular, and easier to find info on, i will probably end up doing this, so if this thread develops to a vast source of information on supercharging a carbbed FB (lets say a 45DCOE ), it just might persuade me. Because, personally I like the idea of superchargers better.

 

it really boils down to a matter of preference when it comes to super vs. turbo.

 

Personally, I feel a supercharger makes tons of sense on a rotary. I mean, the rotary engine isn't known for it's insane torque numbers; so, why not use this, which would give lots of low end power? I mean, it seems as though it would give the rotary a much wider power band...

 

I agree with cpt_gloval and clean85owner. I like the both of them, even though I love my supercharger in my first gen "camden". I like the low end power of things.

In my personal opinion though I think that your motor lasts longer with a supercharger rather than a turbo.

Catch 22 ya know...
My plans are to get another 1st gen and Turbo it, keep my supercharged one now, and actually see which one I love the most. For the right now power hands down supercharger.

 

Code, what are your motor specs and how much boost are you pushing? Do you have any track times or dyno figures? Thanks.
