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 |

(IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif) Yea they do---imagine there is allot of machining and welding up a crank and cam and MAGNESIUM case ( Can you say,,sparkler??) Those engines require even more prep than or = to Mr. Raby does to his to make them a viable high power aero engine If the balances of the entire assembly are off more than .10 inches per second the crank will grenade itself--even at the max rpm of 3600 these engines are rated for--and bye bye propellor--the cranks are rough prepped by CB's--they actually forge a crank just for this purpose---kool stuff indeed
Don't know ifn I would ever get into something like that, manufacturing wise--the liability factor is an ass pucker!!! But it would be kool to see Jake the man do it---400+HP anybody??? I myself have a really doable engine make-up I am dreaming of---it uses the stock bottom end--but the cyl and up is off the shelf from a manufacturer that has been in business since 1908-- Not going to reveal it yet,,need to get measurements and geometric values looked at--plus I don't want to get sand bagged just yet!
