...just to keep the argument going (boy, how I love to tweak those Midget 
guys)...

; )

OK, then would somebody please explain WHY a Midget is so much faster 
than a B in racing form (as you all seem so convinced)? 

Both are unit-body roadsters with similar design, construction, 
suspension, aerodynamics, you name it, with iron 4-cylinder pushrod 
motors in a similar state of tune from the factory.

The B is heavier, wider, longer, with a larger displacement engine. The 
Midget is lighter, narrower, shorter, with various smaller displacement 
engines.

Despite the Midget's advantages of low mass and smaller frontal area, in 
stock form it can't touch a CBB in acceleration or top speed. Not even 
close. Neither did it turn appreciably better skidpad or braking numbers 
in contemporary road tests.

So, given the same racing regulations, if you spent the same amount of 
money on a B and a Midget, how would that make the Midget faster than the 
B? Besides the obvious fact that 14 inch wheels and tires cost more than 
13 inch, and other such factors of size.

If that is your claim, you have to demonstrate that either the A motor 
responds much better to special tuning, or that the handling of the 
Midget responds better to racing modifications; or some other 
asymmetrical process of that sort. (Actually, something of the sort is 
plausible, given the minuscule brakes and general directional instability 
of a stock Midget).

My personal guess, based on the data Mike provided (thanks!), is that 
since the cars are currently lumped into the same racing class (as 
opposed to the old days when they were 2 classes apart), the Midget is 
allowed more liberal modifications and/or a weight allowance, in order to 
make it competitive. It would also seem that this handicap is set a 
little too high for the B -- thus making the Midgets "sandbaggers"!

Now it's Mike's turn to disprove this contention...<g>
