But you can make the same power with less timing and far lower peak cylinder pressures. Probably the biggest mistake people make is running methanol injection and letting the ECU run an aggressive timing map. It may be knock-free but it's certainly going to induce excessive wear and tear.
So glad to see the smartest person in the room from my STi days here in the M5 room dropping knowledge. Appreciate this info
