ive been building rc boats with 2stroke engines for years and now own a hpi baja 2stroke
i know how the engines work but one thing that stumps me is how the cc rating relates to hp and to a lesser extent torque
i had 2 rc boats, one with a 32cc talon engine (cheapie) and one with a 26cc zenoah both stock and both boats weighed the same yet the talon produced 0.9hp and the zen produced 3.5hp! and the zen killed the "cheaper" talon
i also have a 15' halfcabin runabout (real boat) that has a 2Hp evanrude auxilary engine which when i did use it it pushed my 15' boat quite nicely YET if i put a zenoah 6hp engine on it........well it wouldnt move obviously
SO whats the deal?
what do you look out for?
im thinking compression ratio has something to do with it... you can have the same size chamber but one might compress more....meaning bigger boom....meaning more down force....meaning more power???
i dont know.... please disscus
