Technology has come a long way in the car world. Early on getting 100 hp from an eight cylinder was tough, much less from a six cylinder. Now days you can get a V6 Mustang with a base horse power for up to 305. Add a super charger and you can squeeze out 427 hp from the same engine. Yes technology as come a long way. Really?That’s what I would have thought. Super charging has been around in the hot rod, drag racing world, for some time, but in a production, oh that’s fairly new (last 10 years or so). But reading an article from Hemmings Motor New dispelled this notion I had.
So you’re thinking how far back was super charging something for sale to the general public, 60’s maybe…70’s maybe? How about 1937?
Yes. A car company by the name of Graham produced a 6 cylinder coupe.
1937 Graham Coupe
Supercharger badging
That’s a nice looking coupe. Here is a shot of the super charged straight 6 and one of the charger it’s self.
- Straight 6 cylinder.
The supercharger. This was Graham own design of a centrifugal super charger which they manufactured themselves.
They used this first on their straight eight engines then on the straight six. They preformed so well that they nearly equaled the power of the eight-cylinder. The car was lighter with the smaller engine and that helped it hit 60 mph in just 14.5 seconds by producing 112 hp. The car came into chassis lengths 116 inches which had 106hp, 199.1 cid straight six and 120 inches which had 116hp 217.8 cid straight six. What about gas mileage? How’s 23.95 MPG grab ya.
Thanks for reading.
