"OFF" season for 2009/2010
This year has started a little different. With the zeal my son has brought to racing this year (his first serious year) driving the classic Mini Cooper, it has rubbed off on me. We actually installed a couple of those fancy new in car camera in both our cars. Between his camera and his on-track observation I decided that it might be time to check into why my front engined, front wheel drive Aardvark seemed to be so tail happy. I have noticed it over the last year or so but had simply decided it was down to the age of the driver and perhaps the old rear tires. Well, new rear tires for the last event made it better but my laps times are sure slower than a number of years ago. To make a long story short: I finally pulled the original lever shock off the car and found the rear shocks to be frozen solid! The only suspension travel I had was due to tire and chassis flex!
I have now sent them off to be fixed and now very much looking forward to trying out my new car in early spring. I wonder how early I can find a dry place to run it? Phoenix prehaps?

The Aardvark is a front engine, front wheel drive car that weights less than a 1,000 pounds with the entire engine and tranny in front of the front wheels.
The engine is a Panhard 850cc, opposed flat 2 cylinder with a roller bearing crankshaft and "torsion bar" valve springs. This is the engine that powered many of the "Index of Performance" winners at LeMans for many years!
The car was designed to compete in the very popular "H-Mod" class and ran extensively throughout California including Pamona, Torrey Pines, Paramount Ranch, Golden Gate park, Riverside, etc. until 1966 when it disappeared. It was heard of as being in Florida for a few years, but was discovered abandoned in a field in southern California where it was said to have been for the previous 10 years. The car was restored 20+ years ago by its present owner to as close to as possible the original intent =
"A little Aardvark never hurt anyone"
In the late ‘70’s when I decided to get back into racing- I thought it had to be naturally in a Mini Cooper. Much to my surprise I found that any local Vintage clubs would not accept such a common car. It was in fact still being actively raced in SCCA national racing. I struggled with this as not only been the bulk of my experience been in a Mini but front wheel drive cars are what I have always felt most comfortable with.
After I accepted the fact, I spent a little time looking around at other options. I discovered a car not know by many here in the USA but would for sure fill both my desire for front wheel drive and be eligibly for all Vintage racing. The car was a Deutch Bonnet. This was a very famous make in France as they had been Index of Performance at LeMans for number of years with purpose built sports racers. As many companies of the day did, they also built a road going sedan to not only make a similar effort at LeMans but to sell to the public. The sedan indeed also won at LeMans and was as successful in the marketplace as any of the very small, hand built cars of the day. The body and chassis was of their own design but the power plant was from the large scale production ‘Panhard’. These two cylinder engines were designed for economy and simplicity. The Panhard range of cars extended from sedans to trucks. There was even a tank built with a bank of these two cylinder horizontally opposed engines ganged together to form a 12 cylinder power house!

Devin - H-Mod Special

| The use of notched rubber power transmission belts to operate cyclic or timed mechanisms is not unique, naturally, being in constant industrial usage, but this marks the first successful automotive application to our knowledge. Advantages of the 1.5 inch wide belt of molded rubber, bonded to a continuous steel wire base, over the more conventional chain or gears, are many. Lighter in weight, therefore lower in inertia, far more likely to disintegrate slowly than to snap suddenly, and needing no lubrication nor housing, the U.S. Rubber product certainly gets the nod .. if it doesn't stretch. |
| Such belts have been tried on super-chargers to replace V belts, which suffer from considerable slippage, but sheared pulley keys and pins soon proved that their action is too positive. In this cam driving application the belt has proven admirably suited, although many prophesied that under severe acceleration there would be enough resiliency or backlash to foul up valve timing. But, no stretch! |
| A machine adaptation for the front of the cam housing on the Norton head, with its hairpin springs, eliminated the tower shaft and several gears. As she sits, a notched pulley with 28 teeth on the end of each camshaft is driven through its own belt by a 14-tooth pulley on the front end of the main shaft .. a spot formerly occupied by the generator pulley, Two idlers maintain tension. Grafting the Norton cylinders onto the Panhard case required filling the original stud holes with 1/4-inch aluminum bolts and drilling new holes to accommodate the 7/16-inch Norton studs.There is no difference in displacement as a result of the switch, inasmuch as the bore diameter of both makes is the same: 3.12 inches. The Panhard stroke of 2.94 inches produces an oversquare engine. Although the Norton barrels are somewhat larger in overall size due to the greater fin area, there is no appreciable gain in weight, inasmuch as the Panhard is cast-iron-sleeved and the Norton all lightweight alloy. |
| Superimposed over the stock but overstressed bottom end, we find a big-ported head, straight-through porting, monster valves... 1-27/32 inch intake and 1.75 inch exhaust. A compression ratio of 9.5 to 1, effected through the use of Norton hi-dome pistons, is about the maximum desirable for gasoline fed replacement Weber carbs on Y inlet manifolds... one for each cylinder. The flywheel has been lightened through replace-mentl Not to overlook details, Devin whittled out a duplicate in aluminum and pressed on the steel starter ring gear... saved 8 pounds and gained much acceleration. |
| What actual timing he will run on a different "New" engine, Devin keeps to himself. Data on the improved model is also confidential but, as one who has been permitted to view some of the actual construction, we can say that the latest crossbreed will employ FOUR overhead cams, twin ignition and fuel injection. |
