Crazy idea

[Eztrail]

Dual engine 4wd. For offroad Thinking one engine front and rear completely divorced except for both carb cables working off the same gas pedal. Only thing close ish I can think of is cars and cameras 4 engine 4wd kart from like 10 years ago. And it worked well. Any other examples out there or am I going to have to pioneer this ideal?

Interesting...

Gonna be a "1 wheel peel" up in the front
...or dual live axles, with an articulated steering?

I think syncing the drive engagement ratios between front and rear might be a challenge.

Anythings possible. Some things just take longer.

Some karts have have differential axles; most any of the bigger ones like Ken-Bar Sand Dog, Dingo, Deuce, etc., so that would assist the endeavor I think.

Im thinking of using a rzr diff, cv axles hubs and a arms.
I should be able to get the engagement rpm of both clutches pretty close. Just trying to see if there are other examples out there besides cars and cameras

The engagement RPM and throttle synch should not be a problem. I would use differential axles on both ends. I would also gear the front SLIGHTLY faster (lower numerical ratio) to control oversteer. The difference in engagement speed on a couple of small engines should not be worth worrying about.
That monstrosity on Carsandcareras was a nightmare with four separate engines, one per wheel, all connected to the same pedal. It had no issues with engagement.

I'd cut the middle man out and just run one larger engine. Baja SAE is limited to well used to be a Briggs and Stratton Model 19 305cc ~10hp. But a couple years ago they jumped to like a 420cc Kohler that has a restrictior installed to limit it back to like 10hp.

Do 4-wheel steering or take your toys and go home.
