Default RB S9 vs. H9

Can anyone give me a comparison of these two engines? Performance, run time, ease of tune would all be nice to know. Thanks in advance.

i know a guy at my track has a s9 in his cen tr-arena and it goes!! never flames out , on a bad day he gets 11-12 mins a tank and on a good day he can get 14 mins out of her!! good engine for the price but there are alot of just as good or even better engines around for that same price

H9 (5 port) more bottom end
S9 (7 port) more top end

They will tune the same because they use the same carb. RB/ Nova Rossi hold a great tune once dialed in and don't have to be messed with everytime you start the engine. Crank and rod are also the same. Want to make both of them even better, put a turbo button on em. Runtime is hard to say, it depends on what restrictor, fuel, pipe and tune you put on the engine.
