So if one were to mount a bike motor transversely with a direct (guibo) connection to the rear axle, on most bikes one would end up with a left weight bias - not so great on a left-driver car. So what if you were to shift the entire thing over a bit to compensate? You'd end up with unequal half-shafts, which I understand isn't so hot - particularly in front-engined situations. Does anyone have knowledge and/or experience that can be brought to bear here? Is it a big no-no, or not really a thing in RWD applications?
On a related note, does anyone make a rear axle without a really long nose cone? What can be done to get the motor close to the axle without using a chain?
The FWD torque steer does not apply to RWD applications unless your toe-control in the rear is deflecting (which it certainly shouldn't). What does apply is axle-torsion and it's effects. Basically axles twist when loaded, and different length axles would need their thicknesses adjusted so that they twist the same amount. Also, I *think* Torsen diffs hate unequal torsion.
Pretty sure the FSAE guys have dealt with this. Maybe peruse their forums about it.
The smart-ass in me says that BEC have no torque so can't twist anything enough to worry about.......
