A four cylinder mag on a three rotor?? Vance

Good question. How does that work Paul?

The magneto is a 6 cylinder Bendix - a four pole mag geared 2/3 inside for
six cylinders.
My gilmer drive is 2/3 to get the right rpm, and I run two leads to each
plug.
I have charts etc on how I worked it out if you want.

I have installed lots more dowells in the engine, but Ibarra and Signorelli
and other hard
hitting rotor drag cars still have the twisting problem - I believe it
cracks the rear housing.

I would be interested in the charts.

OK a big box on the bottom will do the job. You should use carbon fiber
however as it has a higher shear modules of elasticity to weight ratio
than either aluminum or steel. Both of which are the same BTW.

Giving it a little more thought you kind of have limited room under the 
engine for a big box.

How about a large properly triangulated space frame using steel tubing 
surrounding the entire engine? Front and rear motor plates. That would 
give you a front chassis structure to hang the front suspension off and 
give you service access to the the engine.

I'll do a 3D of what I am talking about.
