Foster V12

Postby Reklaw » 07 Apr 2013, 15:08

At Narrandera, Greg and I were discussing heavy things, like starter motors and large batteries, in lightweight skiffs. Discussion then turned to an Australian built racing engine that required neither. It’s called the Foster V12, here’s a bit of a story on it.

Firstly the man behind it. Fred Foster had an engineering shop in Mascot NSW. If you have some Foster Stocks and Dies in your shed, then you have some of Fred’s products.

Fred designed and built the first twin overhead cam conversion for the Holden grey motor and went on to break the world record for the 135 C.I. class in his Lewis skiff, Fossy, using that engine. You might have heard of a Waggot twin cam Holden engine but it’s not widely known that Fred did the first one. But back to the V12. …..

Fred wanted to do more and one day a friend showed Fred his Ferrari V12. So Fred did what came naturally to him and drew a V12 out on the concrete floor using a piece of chalk. He then went on to build his own V12 motor, casting the alloy block, machining the crank etc. It was aimed again at the 135 C. I class and came out at 132.9 C.I. There were a couple of things Fred didn’t make himself. This included the bearings, the valve springs and the distributor caps. Not visible in the photo below, the distributor caps are bright pink. Fred made a metal cast and had a Dentist friend mold the caps for him.

However, you can clearly see the starter motor in the pic. It’s that pulley with the cable would ‘round it. Fred thought that starter motors and large batteries could be done without, thus reducing the weight of the boat. He just used a motorbike battery for ignition. So, it’s a bit like a lawnmower, you wind it up, pull the pawl and away you go.

Terry Moran, owner of Bewitched (see my avatar) was “apprentice” to Fred for many years, helped Fred with the build of the V12 and quite often drove Fossy. Terry has the V12. It could still be started today, with just a little prepatory work required. Who knows, it might end up in a little skiff again one day.

Sadly the same can’t be said for Fred’s twin cam Holden motor. When Fred’s health started to fail, he offered the boat to Terry, but Terry declined the offer. I guess we’ve all been in a position where we have regretted a decision made some time ago. Anyway, Fred sold the boat and motor to a friend who didn’t see the significance of this great part of boating history. After all, it claimed a world record. He ended up taking the motor to the tip and the hull was left laying in long grass beside the road ( Darren, across the road from Roy Crouch’s place) in a very sad state. We looked at it once with a view to trying to salvage it but dismissed the idea. We now wish that we had grabbed it back then.

Great story,the motor looks like it could do the business,was there ever any perfomance data on the engine?
cheers

Jeff, no there's no performance figures available. This all happened in the '50's so not sure if there were many engine dyno's around then. I can recall my father saying that, during initial runs, it would do 6,500 revs on one bank, 6,500 revs on the other bank, and 6,500 on both banks. There was obviously more development work to be done, but Fred's health issues started to get the better of him. Terry has since made some changes and one day we might find out what it will do now.

I tracked down the specs of a 1947 ferrari engine i think packard might have orinally designed it back in the day any way here are the specs of a 93 cube v12 with rpm of 5600


engine V12 position Front Longitudinal aspiration Natrual valvetrain SOHC 2 Valves / Cyl fuel feed 3 Weber 30 DFC Carburetors displacement 1496 cc / 91.3 in³ bore 55 mm / 2.17 in stroke 52.5 mm / 2.07 in compression 8.0:1 power 53.7 kw / 72 bhp @ 5600 rpm specific output 48.13 bhp per litre bhp/weight 96.0 bhp per tonne

Thommo there exists a v12 grey motor. Its called a wallbank and was never completed.
A guy i know has it. The guy cast his own crankcase. Used grey motor internals and two repco cross flow heads.

Hi Tommo,
Yep, thanks for posting those pics. I have it from a pretty good authority (the guy who helped Fred design/build the Twin Cam then drive the boat that it was in) that the engine shown (the last shots of course) are not Fred's engine. Reasons are ....... The valve angle is incorrect, should be 60 degree, the distributor location is incorrect, didn't have those bronze Amals on it etc.
As far as we can ascertain, Fred's engine went pretty much from the boat, when Reg King owned it, to the tip. Reg told me that it had corroded through, so he just took it to the tip.
We can't imagine how it could have ended up on an engine stand and have (new fangle) colour photos taken.
Fred did however lend the patterns to someone so that a motor could be made but, presumably, it would have the same 60 degree angle as Fred's motor.
So, this is intriguing and begs the question "where and when were the photos taken and what motor is it?"
Looking forward to hearing from you on this.
Bob
