RS 61 / 547 race engine questions
I am researching the 547 race engines used on 718's, RS 60's and RS 61's. The literature is kind of vague. Anyone know the rod length and ratio, intake and exhaust valve sizes, and the intake and exhaust valve lift / duration?
I know the engine had a 66mm stroke and 85.5mm pistons....must have been a real high revver!!! Anyone ever dyno a Carrera engine like this and have HP/Torque numbers?? The HP quotes are all over the place in all the different books.
