A .32 = 3.5 + horsepower according to almos every r/c engine manuffacture.... so a .46 can produce 5hp... isnt too much off.... unless of course, the entire r/c industry is lying
2 engine dyno can have up to .5 hp difference on a .12 engine... so on a .46 engine, margin is up to 2hp...
It says on hpiracing.com that there .46 ho motor makes almost 3hp
