when i was running my CY with race ported and 35mm piston and using a +2mm stuffed crank it was pretty powerfull but lacked rpm , then i installed the TS induction crankcase still using a 35mm race ported head with +2mm stuffed crank and the rpms increased dramatically , so does this mean if i go with a (36mm) ESP raceported head still using my TS crankcase and +2mm stuffed crank i should still maintain those extremely high rpm's but get even more HP with more torque , its something thats been bugging my mind and ill never know untill i buy this ESP race ported 36mm head kit and test it out , i hope to get one in a few weeks , thats if DDM isnt sold out again LOL
Yes, the bigger bore should give you more power. I don't have any experience w/the RC case reed engines [ next on my list!],but I can see how the reeds being in the case verse the piston port intake extends the usable rpm range of the engine. The case reed starts pulling in a fresh intake charge sooner than the piston port motor and that helps w/power all across the board.
