[Land-speed] Multiple Engines

Having never done done this but intuitively I would separate the firing 
points 45 degrees EX if engine 1 were to fire at 0 BTDC I would have engine 
2 fire either 45 BTDC or 45 ATDC to fill in the time between firing any 
other choice would have them add to a higher torque level for the rear 
crankshaft. Obviously you need to add the ignition advance and only used 
those numbers for easy math..
BTW thanks for the racing related post!!!
