But the power cannot go up at the same rpmif the torque doesn't, which means that there has to be more load on the piston, conrod and crank (as well as all the inbetweens) and so it goes. If it was RPM increase alone then sure, inertial forces increase, but more power at the same rpm means there is more air going in, therefore more fuel required for a stoich mixture, so a bigger bang must result.
I'd run a little extra power until you are able to get an oil change/oil analysis done, then plan the next power increase. Fuelling is not an issue for your setup though mate.
Your call.......
