"i make learning FUN!" - strongbad of strongbadia


anyway... recalculated velocities using bills method:

if max mean piston velocity at 8500rpm is 4777 ft/min

drumroll please....

intake velocity across the 45mm throttle is 286 ft/sec! bingo! this is also the cross sectional area (and heance intake velocity) of most of the port (not including the bottle neck region) and is also the surface area of the valves Very Happy

yet another piece of data that fits in perfectly with the proposed design.

(now to contemplate the consequences of a max mean piston velocity of 4777 ft/min!!)
