Not to speak of. I ran my Hyperpak XT550 at sears point to a very high RPM -- well
beyond peak torque with my 266-x4 megacycle top end. Probably about 8500 RPM. Never hit a hard limit on the ignition side, just a subtle release in arm stretching surge that told me it was time to shift; way higher than the 7K RPM redline on my stock XT600.
