Supercharging

This might not be the right forum, but I'm curious to know if anyone has supercharged a Model A motor and if so what type of supercharger did they use, what carby, and what were the results?
Thanks,
Keith
 
It is the wrong forum. You want the hamb, the monthly banger meet. And yes someone has supercharged a model a. I saw a youtube video of it.
 
Yeah, it probably not the right forum but since you asked, the simple answer is Yes, ...I used a McCullough(??) centrifugal blower off of a mid 30's Graham Paige but if I were to do it again I would probably use an Eaton supercharger off of an early 90's Ford 3.8 litre Thunderbird just because of the efficiency. My suggestion would be to go to H.A.M.B. and look around there. I think there are several pictures floating around there of them, installed on bangers including my old 'McGuyvered-up' mess. :)

Welcome to the Ford Barn, not everyone here is a card carrying Fine Point restorer, I for one enjoy learning about Ford history both factory and post showroom. The Model T was supercharged for dirt track racing in the 1920's. Robert Roof, Pop Green and the Chevrolet brothers all offered blowers for the T, but I've never read about one for the Model A. I'll go through my literature collection to see if in fact one was offered in the Pre WWII era. Best wishes, Bob

Well, Bonneville season (just passed) saw 'four barrel' A/B records set. I think that one of our own..here...mabe set a record supercharged ! Mabe J. Brierley can comment on the use of this type equipment :) !
 
One thought about supercharging that I feel is especially applicable to ancient engines: High RPM's are much more stressful/destructive than added loads from power. Most engines (normalish engines, not thinking about Formula One or blown fuelers!) are actually more stressed at the top of the exhaust stroke when centrifugal forces on rods and moving parts are highest than they are on the power stroke.
The advantage of supercharging is that unlike many other modifications it does not require high engine speeds...blower speed can be chosen to produce boost at lower RPM's and so avoid radical increases in stress on scrawny old cranks and long, spindly rods. Seems like something to consider.
 
Yeah Hardtimes, that was me on the salt with a Buick turbo. The stock turbo puts out 6 PSI, I shimmed it this year and it was pumping 9 PSI. 165 through the 3 mile was my best time. Turbo's are easy to mount (no gear or belt drive needed), and they are efficient. I've also seen the Ford "Turbo Coupe" turbo's on Model B's. The easiest way is to have the carb before the turbo. Next year I plan on using all 4 carb venturi's, I've been using only 1/2 of a 750 Holley, bring a basket! Through the years many types of blowers/superchargers have been used on bangers of all sorts.
 
heres my old one

Thanks team, It's given me something to think about.
From past experience (MG's) superchargers can make inefficient engines much more powerful without resorting to camshafts, high compression etc.
When I get my speedster on the road. I'll start exploring supercharging
