I want to have some "consensual" induction in my v6 miata. Non turbo, because i don't want to rebuild headers and exhaust, and dont think i could package and cool it properly anyway.
There isn't a lot of ckearance, and i dont want to cut the hood for a roots style blower.
Has there ever been a factory centrifugal supercharger? Possible to junkyard source?
There's the G-Lader scroll-type superchargers VW used.
I know we probably talked about this at some point... but cant you drop in a different 60 deg v6 and get like a ton more power (and more rpm)? Or is that not easy (er than boost)?

Umm....
Care to educate me on this? Never hear of them
In reply to ProDarwin :
Yes-ish. The 3500 can be gotten with another honest 30 horsepower. And then cams and some other work gets a ton more.
But......
BOOOOOOOOOOOOOOSSSSSSSSSSTTTTTTTTTT!!!!
honestly, it'll probably go bigger engine. Or supercharger, then bigger engine WITH supercharger.

Not centrifugal, but not a traditional one either.
Probably a good reason they didn't see more widespread use, though I thought M-B did something with them as well

Ah I'm reading now. I thought the 3900 would drop in which would bring an extra... 80hp? But it looks like enough changed to make that a pain.
In reply to ProDarwin :
I thought so too. But rob proved me wrong. Id have to build all new swap parts, and thats a nope. Same with the vvt 3500.
So, not a ton to be gained, but some as a bolt in. Cam, compression and porting give more.
Well, there was the GT350 Shelby, and some Studebakers if I remember correctly, but that's not really helpful.
The V-dub is probably your best shot.
I thought there wasn't any room left under that hood?
In reply to RacetruckRon :
Not much. Not much at all.....
But i can fit a centrifugal where the ac compressor was. I think. Maybe.
Scion had a TRD centrifugal, but looks tough to retrofit and mixed reviews on reliability.
R-code 1950's Fords like the Thunderbird had an ancient Paxton centrifugal. There was also the R2/R3 Studebakers with centrifugal superchargers. Roush had some, but good luck finding one of those in a junkyard. There's been a few factory accessory/dealer add ons, but nothing that you'll find used.
Half a turbocharger with a gear box ratio to drive it fast enough off of a crank pulley and bobs your uncle?

Figure out how i can do this in my shop, and hell yes!
I seem to remember that Ford had a Paxton supercharged version of the '57 Thunderbird.

Or just let your exhaust spin the compressor for you...
Perhaps a remote turbo could keep your underhood clearance without major reworking of headers or swap stuff?

Ghats not a horrible idea. If stampie strikes out on the millennia supercharger, that may be the next best option.....
The Thunderbird Super Coupe had an Eaton style blower that was inverted to feed a remote mount intercooler. So it was in the valley per say but didnt blow "down" into the intake manifold. Instead it blew into a top mounted manifold which then fed to an intercooler mounted by the radiator which then fed back to the intake manifold behind the blower.
Maybe take one of those and mount it off the side and plumb back to your stock intake? They even had a nice little intercooler that would be easy to mount as they were quite compact.
In reply to kevinatfms :
I think Jaguar did the same thing on at least one of their supercharged cars in the 90s or early 2000s. Eaton blower set off to the side and ducted to the intake.
Not much help for Duster, but answering the original question: Cord, Duesenberg, Graham and some others used a centrifugal super charger in the 1930s.

I've wondered about mixing a smaller SC with a clutched pulley for lower rev response, along with and to help spool a decent sized remote mount turbo. Ideally fit the turbo about where the cat is packaged. Would take maths and likely some complicated intake plumbing with controllable valving, so haven't done much more than daydream about it.
Kawasaki H2? That's modern, good luck finding one in a junkyard though
