Not heard anything about the torques before mate.

wouldnt have thought it would put a limit to anything, and would have thought its as strong as the f15

I think the acceleration would be quicker and the top end less like said, but also wouldn't the f13 take less torque? Therefore not last as long, and put a limit to engine modifications?

would you notice any difference from changing from a f15 to a f13cr (close ratio)?

pros and cons in doing so?
