RE: PowerHouse RC Performance Race Engines
is the CB66 the one in slayers pics? if so, which ports are the "center"....
yes. much much more perameters- however, before any further discussion takes place, i have had limited exp in modding small nitro motors. ihave only done one, but that motor was incredible after i finished. im gassers now, so that changes a few things, but the theory is constant. as far as perameters are concerned, i touch on EVERY aspect of the motor and pipe.
"The transfer ports should be fairly flat (10-15 deg) compared to the boost port (50-60 deg). How would changing the transfer angles increase throttle response an efficiency? " lower angles promote higher peak HP values, but higher angles support the powerband under the peak, so an adjustment there could yield better cyl filling at lower RPM's, and thus having noticeably better responce-
