Multiple engines legal in racing?

I've been researching the posibility of using a V-6 two stroke marine/cvt. That may be a fun challenge. Anyone got a merc outboard their not using?

I've thought of outboards on occasions too - electric start too. Does their cooling tract use conventional plumbing fittings, or are they just holes in the castings? Cooling is the only grey area I can think of.

What's their CVT like? I didn't realise they used them in outboards.

The ones I've checked out had the water dump into the exhaust. I hadn't gotten har into it cause a book I tried to get, wasn't available. "Olav Aaen's TWO STROKE RACER"
Anyway, a custom two-stroke head wouldn't be that tough to make right? *Oh, the clutch would need to be fit on the pto end custom I would expect. The crank pto fit with a taper to match a Comet clutch. Maybe Comet already has something worked up.

If they're anything like a jet ski is - they dump the water from the head into the exhaust via a tube of some sort.

The water is sprayed into the exhaust gases and helps dampen noise (pre-muffler) and carries away heat in the exhaust gases. *

If they transfer the cooling water from the heads with any external fitting, you have a shot at a closed loop system...

That's what i was wondering. if it's possible to incorporate a closed cooling system, then you possibly have a winner.

I haven't seen the end of an outboard crank, but I'd be very surprised if it's not possible to bolt or graft something to it.

There was a guy using two hyabusa motors in a rally car a few years back in the UK after half way through the season they decided that it would not be permited to race *the following year as no one could beat the thing a bit like the 6R4 when Tony Pond raced a mini metro with a V6 bolted *into the back seat of the car. Here is a site for motor cycle powered cars showing a V8 busa http://thekneeslider.com/motorcycle-powered-cars/

Again, CAN'T BE DONE? How about alittle 2 stroke pipe music.

alittle? *Is that the opposite of alot? * *[smilie=non_banana2.gif]

I can't imagine what that sled sounds like. *Needs tuned whistles on the end of each one. *Toot, toot TOOT... *Pipe organ style.

Check the dual coil ignitions and the wide spark plug placement for each jug. *Wonder what the ports look like? *Probably cavernous.

It looks more like an anti-aircraft weapon than a sled. *- *for some strange reason, I like it. *

They built 3 Boss Cats for top speed runs back in the 70's. #1 was powered by a gas turbine. It blew up. # 2 has a blown 427 and ran 180mph, # 3 has 4 1973 Kawasaki T8-RX 650cc 3 cylinder two stroke engines. The port side engines run clockwise and the starboard run CCW. Each engine has a CVT clutch with belts running to a common main shaft that runs down the center of the machine into a T gear box to drive the twin tracks. It's top speed was 139mph which was preaty good for the 1970's. #'s 2 and 3 are now owned by the same guy as part of his collection Multipal CVT's running a common drive is not a new idea.
