Front mount blower

smitty2 · February 13, 2009, 01:27:01 PM

DrofRockology mentioned front mount blowers in another post... I was wondering who it is that is producing it? Is it just for Chevy/Ford/Mopar, or is there a "Universal" mount available?
Am I asking too many questions?

These guys http://www.thesuperchargerstore.com/ make a set up to run a Procharger off the front. If you wanted to run a conversational style blower on the front it wouldn't be that hard to fab up something. I built one for my GMC 6 and couldn't fit everything in my roadster the way I wanted, so I went with a reverse rotation Procharger instead.

Thanks Mag.. those are some sweet set ups.
I have a 4-71 that I have rebuilt, and was hoping to mount it in front of a Chevy 153 inch Banger. Since I'm on a starvation budget at this time I believe I'll end up machining something up in the garage. I'm open for suggestions

Thanks... Smitty

"Potvin" front blower drive ... havent been manufactured for quite awhile ... check ebay or surf the web for old racing equipment ... JD

Smitty, You could run a bellt drive or a Lovejoy connector http://www.lovejoy-inc.com/ and then fab up a housing around it. Also Steve at uncommon engineering http://www.uncommonengineering.com/index.html (about half way down their is a picture of a 471 on the front of a flat head Ford) has a coupler he made for a 471 to flat head Ford. Try giving him a call and see if he has coupler for your application.

Tom Cobbs also made some front mount supercharger stuff. I own one of his units for a small block chevy.

Potvin! that's the name I was trying to recall. The Mooneyes rail has a Potvin front mount. I was looking at Marlo's Streamliner awhile back, and it seemed to me that his was a belt drive arrangement... pretty slick setup. I will look at EBAY and see if someone has a setup that will work for this... If not I'm kind of looking forward to a fabrication project

Thanks.... Smitty

Moon Equipment may be able to assist with Potvin drive equipment.

Come on guys! You have a shaft that needs to be turned ,the blower, and one that is turning, the engine, any of us with any level of fab ability can make that happen. I would probably go with standard blower pulleys and toothed "rope" to drive it. Lay the blower on its side, I'm talking 4-71, 6-71 etc GMC style roots blower here, with the inlet on one side and the out let on the other and I think that the biggest fab challenge is making a good plenum between the blower and the engine. Important to get the air slowed down and going in the direction of the inlet ports so I would do some sort of turning vanes internal to the plenum and I would make it BIG with lots of volume to get max pressure, evenly distributed to all cylinders.

There is a NOS Potvin setup on Ebay currently.

I've seen fotos but never seen how, if you just placed the front of the blower to the front of the crank it would be turning backwards so they do something to drive off the rear of the blower??

Ken Walkey had a 671 style front drive on his chev streamliner, try talking to him. I always thought a front drive on a roots blower would be a good idea and if running gas you could plumb in an intercooler.
But i would never run a roots blower on gas.

John,

If you look at the front of a GMC blower all belt drives come off the right hand rotor. When you use it as a front mount you use the left rotor to drive the blower. Since GMC blowers just use two gears to turn the blower rotors one gear turns clockwise the other turns counter clockwise. Hope that helps.

Tom, that Hot Rod pic is just TOO EFFING NEAT!

That's beautiful but no aftercooler! Does the car have a radiator?

The picture came off the internet so I really don't know if it has cooling or not.

I have a front mount for one of my Desoto's. I really want to put it into a track style 27 Ford T Roadster. I always thought it would be cool to have a long nose with the hood hinged in the front. Just for looks put a 14-71 Hi Helix on the front with electronic FI, and a set of Howard's Aluminum Desoto Heads.
