what do you think
if you where to put two bike engine driving the one diff what advantage would yo have.
would you see the power diffrence.

Haven't you asked this before!

I think it look slike an interesting idea, you could even have the second engine easily removeable so you could replace it with a passenger seat! Good
for weight balance and a great talking point
Don't let people say you'll never synchronise them, it really doesn't matter. Unless they are massively out of sync the torque
output of both will still be added, you would need one engine with it's throttle almost down to idle position for it to start providing a
resistance to the other engine.

Now, if you want to get really clever, forget this idea and have one engine driving each rear wheel (a la NS Dev I believe?). Then program an ECU to
distribute torque appropriately between the rear wheels based on weight transfer and available traction. You could use either a transverse
accelerometer or sense wheel slip.
But I digress ...

Thing is, a bike engine is great because it has a high output for it's mass. Max output is limited though. Once you have two of them you are up
to car engine+box mass, and you could tune a car engine up to the power of two bike engines pretty easily with well-proven components and you
wouldn't lose the passenger seat. Wouldn't get the sequential gears or F1 soundtrack though.
Great for a talking point and an engineering challenge, but maybe not that practical!

Didn't tiger do a 2xBEC car? Was on 5th Gear? Vicki B-H tested it.
I'd drive that into next week. And the car too.
