Has anyone tried to build a flat 8 with two type 4 motors?
Theoretical questions. Assumptions 2 motors each producing 100 HP and 100 Lb/ft of Torque The motors are end to end, front to rear. The cranks are fastened together either bolted or welded. 1) Would you get 200hp and 200 lb/ft or torque? or is there some multiplier...seems like you would produce more torque.. 2) could it be done with a single ignition system available for sale off the shelf. 3) could you do it without two distributors? crank fired ignition system..I am thinking that there could be a wheel placed in between the motors to give you something to time from. 4) I am assuming either a nice FI system, or four carbs. Has anyone done this? I would like to see some articles or web pages if this has been done in the aircooled world... Thanx in advance Rich |

Very nice pic of a Duc!!! I am spanking to it right now----always wanted one--900SS super light was the one that I lusted for--
I did not mean use the valvetrain--no--I was thinking of the inherent smoothness of a 90 crank--but because the cylinders are still 180 deg. the extra two throws would balance out like it was a 90 deg. crank in a 90 deg. cylinder layout- And yes-those cam lobes would have to be whittled down in width quite a bit--but it could be done...... |
