Is there any reason why a flywheel designed for a 4 cylinder car won't fit on a 3 cylinder car? I'm wondering whether the imbalance of the 3 cylinders may need a different flyhweel??
Any help greatfully received.
Hmmm. I'm probably no better bud but are the weights to offset the missing section in the push cycle not incorporated into the crankshaft instead? Three cylinders and four strokes and all that? The flywheel carries the rotation through the lacking phase to prime the next compression so I think it's just the mass and size which vary to give sufficient retained energy for the compression, smooth out the power cycle but not introduce too much lag... of course that might be bollocks.

There is a separate balance set up, flywheels need to be perfectly balanced and so a 4 , 5, 8 , 12 cylinder flywheel at all just balanced regardless of the number of cylinders.
But that is not the only thing to consider, fit and weight and diameter etc. have to be spot on. I wouldn't consider fitting a nin standard one.
Having your current flywheel lightened though is an option, it gives a quicker throttle response, especially on a tuned engine like yours.
