what type of car are you taking the fan out of.. because I am sure if you look hard enough online you can find how much CFM it moves (cubic feet/min)
Which will later on help with calculations.
You need to be a little bit ore specific.. which type of lawnmower?- riding, sitting? how may HP or CC, and Second you have to make sure that the fan you are using is rated for those types of RPMs if not then you will just blow the fan apart.
Hey, i have an 11 HP engine which will be driving a fan for thrust via (v-belt). What do you think the best ratio for pulley size would be for the fan and the engine without being too hard on the engine. but will allow a very high RPM for the fan which is about 32' or 36' (diameter).
right.. so what is "middle ground"
Anyone know what would be best...
small tinny holes, medium holes, large holes, one giant hole, small surface area with lots of PSI or large area with low PSI.
Yes, i have seen that. But i am not sure why pushing it all to the edges would do... You have higher air pressure but a lower surface area. so I am not sure what would be best.
I am doing a riding hover craft and not a R.C verson.
My specs
-4"x6" feet
-11HP engine for fan/thrust drive...
