Engine and gearbox inertia

[robertson86]

hi all, I'm trying to write a vehicle acceleration model in MATLAB as part of my university project and I really need some help finding values of polar inertia for the engine and gearbox. Im doing this model for our Formula student car which uses a Yamaha R6 engine and gearbox, does anyone know roughly/exactly what the inertia of these is?
Otherwise if anyone knows the engine and gearbox inertias of any car/bike I can use these and scale them down. I've tried searching all over the place and haven't been able to find anything so I hope someone can help.

Cheers, Iain

I am not knowing any specific value of inertia regarding engine or G/box, also because usually the main concern stays on the overall car packaging, intending to minimize car inertia by adjusting mass toward the CofG.
The challenge remains the same, reduction of any weight, even low value, at the car 's extremities is always important and key factor when designing a car or improving performance ( 2kg at 100 cm from CofG is equivalent at 20gk at 10 cm from CofG ).
