max CFM required by engine
does anyone know what the max CFM for this motor is? I got the formulas to do it, but I wanted to compare results, or see if anyone already knows the answer to it. I will run my numbers and post them tonight.

i have 2 bilge fans, 3 in, 145 cfm each. both in front ducts. i guess this is limiting at full speed.

If you position 1 fan on the rear to draw heat out of the hull that would be fine at low speed and part throttle cruising,but at WOT the fan will being working against the engine because the engine will be trying to draw air into the hull through 3 inlets while the fan pushes it out of the fourth. that means the engine will have to pull its 333.62 through 3 inlets,or 111.20 through each of the 3 inlets. Thats 27.70 cfm more than stock.

Could some one smarter than me please tell me how much air a 2 stroke 1500 cc engine would need.
