Hot Rods need info on dual flatheads

Will more than likely go with chain n sproket, but might weld the two sprockets together (behind #1 & in front #2) That'll intensify things a bit, still a lot more to figure out as I proceed, (linkage,shifting,fuel,cooling etc) but this feedback answer's my concerns before continuing.

Or use a solid tube welded to flywheel and one to crank yada yada,hmm. Bumpy California roads.

 

I would avoid welding anything to the crank. If you want to use a 4 row chain just get two Harley Motor sprockets. That gives you 4 rows. You could even get crank pins to go with them and weld he crank pins to your spuds. that way you can change sprockets if or when they wear out.

The nice thing about the motors being coupled and not sharing any running components is that they don't have to be synchronized. Not like the Daimler I posted. LOL The closer the output of each motor the better obviously but you do got a little slack. Something that will help with the tuning is to get your initial setup with the motors uncoupled, that way you can get them the ramp more evenly without the one motor trying to pull the other.

If you can adjust the position of your sprung weight it makes it a little easier to tune your ride. IE Try to centralize the position of the motors as much as is feasible. You can go all Big Daddy Roth on it with coils on all 4 corners and a main leaf to locate your axles too. With the coils supporting the weight it will improver your ride a ton.

OK not building your car for ya, just thinking out loud.

 

Best answer ever !!
