Reduction ratios
Discussion
Tell me, if bike engines rev to (say) 14K (and 70mph in first), and produce 70ft/lb... why not gear it to the car equivelent of 7000 rpm (therefore 35mph in first), thus doubling the effective torque??
I've been puzzled by this reference to "low" torque for a long while now - surely it is just a question of gearing, or have I missed the point somewhere?
cheers, Carl

IIRC in the Civic type-R thread this was discussed, and it was said that a high revving engine can take advantage of gearing to put more torque down on the tarmac...
Often wondered the same thing - wanted to put a bike engine in my brother's mini - thought about using the standard mini gearbox with the mini clutch directly onto the bike propshaft or vice versa and a low ratio diff instead of a reduction gear or reworked gearbox to do the reduction (save money/space & stronger therefore more reliable I thought)
Never did get the idea off the ground though - don't know enought to do it myself, don't have the tools even if I did & can't afford to pay anyone to do it for me
