More R/C HYPE
In theory the more pent roof/shape charge effect= more HP, but in reality as far as
r/c engines, I can't find a differents. I went from standard to turbo in my Nova
367 and losted alot of bottom-end. I went from turbo to standard in my Nova FMS to lower the cooling head and lost no noticeable power. I know turbo plug engines are harder to tune, so that should give you a good indication on how efficient it's combustion chamber is. Just my $.02
