This is mostly a question for Scawen, but if anyone is able to prove it experimentally, I'm also interested.
Assuming constant RPM and throttle position, does LFS model engine torque output as a single value? Or does it oscillate with the crankshaft phase based on the power pulses (e.g. a spike in torque every 180 degrees of a 4-cylinder's crankshaft rotation)?
I'm not sure how applicable it is to cars, but at least for motorbikes, a lot of people seem to be of the opinion that wide, uneven spacing of power pulses (such as in the case of V-configuration engines, or "cross-plane" crankshafts for inlines, e.g. latest Yamaha R1 and M1) is beneficial to a rider's ability to "feel" the level of grip under acceleration at the limit, compared to evenly-spaced power pulses that nevertheless may still experience some oscillation in torque output.
If no such torque oscillations exist at all in LFS, what effect they would have if added, and are they worth the CPU time?
Does the mass of the driveline and/or vehicle damp such oscillations to the point they're practically non-existent?
