Wow. Russ and everyone else saying its hard to turn a live axle on pavement. Well guess what ITS NOT HARD AT ALL!!. Just like kenny mentions race karts with 1 1/4 live axles. Just like my jr dragster. And I have two slicks 8 inches wide each and its not hard to turn around at all.

But when you blip the throttle your 70hp dragster will probably go sideways if your not careful. According to wikipedia, racing carts work on frame flex to lift the inner wheel in a turn.

Actually I said 'tendency'. I haven't actually experienced this problem but have read it on earlier posts on older threads.

My experience (or lack of) has shown that karts like my Manco (soft spongy wheels in back,rearward weight bias, live axle) DON'T like to turn, BUT, it'll darned near climb a tree.
On the other hand, live-axle karts with a decidedly forward weight bias (rhymes with My _ss!) like my green kart corners beautifully. I'm thinking that's why the Kibble-Type karts with the live-axles do so well- what little weight they have is the driver, which is towards the front.
After "weighing" (pun!) the pros and cons, a person would do well to build a twin engine kart, each motor driving it's own wheel, throttle synced together. You have no mechanical connection between the inner/outer wheels in a turn, twice the power means taller gearing is do-able, and the penalty of the extra motor/drive would be neglegible compared to the overall weight of kart and driver.
I say that oughta be our next collective project, Kart-kateers!

Roy Vanas has got a hell of a start, with that frame.

Correct me if im wrong but when a cent clutch engages its engaged, so the drawing up top would work only if there is enough force to break loose the shoes from the housing or im completly wrong.

The way I see it working is that when you're accelerating/going straight, the clutches engage making both wheels rotate. When you're turning, assuming you're not accelerating in the turn, the clutches aren't engaged and so both wheels are free to spin freely.

Lol yeah true. I can do 20 foot+ water burnouts but where not alowd to do john force style burnouts (meaning front tires crossing staging beams during burnout) And wikipedia is correct. If you have ever sat in a race kart before and cranking the steering all the way it actually visably lifts one rear tire.

there are no lockouts on a centrifical clutch...it wont just stay engaged it turnes great either way you turn.
p.s. sorry for the blurry pictures

Unfortunately, I can't drift, well, much. I did manage to break loose once at the school yard and drift for about a 1/4 of a turn.

Try the infield of your local baseball field. I can drift all the way around the bases w/ my live axle kart. That pebbly sand is perfect for drifting.

i once saw a twin engine go kart. both throttle cables were hooked up to the gas pedal... but here's where it gets weird. after being hooked up to the gas pedal, the cables were attached to the steering shaft somehow, so when you turn... one engine accelerates faster in a corner. but when going straight, both engines are reving at the same speed.

you could always set up 2 hand controlls that also do the steering and a foot brake
like a tank
