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 |

Nathan, I second that! MotoGP sould be great this year!
Duck, good point!!! Even though the Desmo is an awsome working system, the adjustments that are required to keep them up to spec are extreamly time consuming. Its like the early 356 Carrera 4 cam motors... book time is 40hours!! I'm not kidding. They figured it would take you 3 times to get it right... Its all bevel gears and shafts, first you adjust the exhaust cam, then the intake cam. Pro's know how to compensate so that once they tighten the intake cam gear, the exhaust doesn't move. The good thing is once the adjustment is done, you never have to adjust it again solong as nothing breaks! |
