600cc engine on racing kart frame

Wow that's a wall of txt...
Please break that up into paragraphs... As that's what and why they are called that for.

So.... Just curious.... What is the OD of the front tires you will be using?

All I can think of is Wile E. Coyote with a giant fireworks rocket strapped to his back and roller skates on his feet.

This is the real coyote kart

I think the fronts are 10s

 

[mckutzy]

You think the fronts are 10"....

I'm no expert.... But clearly you don't see a problem here........ Brake related at least.....

 

[itsid]

but think about all the grip he'll get running 12" discs on 10" wheels...
he'll mill his own slots in the road ...

like a train!

I see no problem at all

........ Ahhhh,
I was waiting for someone to notice....


Ahhhh I'm going to guess.... Kart brakes are only going to fit....

I like the riding rails statement. Kinda cool idea......

Maybe you could use that break on the rear axle? I am assuming that chassis doesn't have front brakes already.

Hey x5050 Aren't you the guy that was gonna try something like this last summer. What happened with that?

 

[KlaudioP]

Yeah, I'm putting one hydraulic on the back and two on each side at the front.

The chassis doesn't have front brakes but upgraded stubs and hubs should do the trick

 

[mckutzy]

Ya that maybe so.... But you ain't using the rotors fo sho... Too big.

With that being said, using the same calipers the fronts going to need floating rotors as there is no movement with those. (off hand I'm pretty sure they're floating, but I doubt you'll find any that small)

 

[KlaudioP]

Yeah I'm going to buy a front brake kit off ebay which has the stubs and hubs and discs and this kit would have come off a racing shifter kart, The biggest brakes I saw was 4 piston but I want to use the 6 piston because they are more power. Also I am looking for conventional floating, circular discs that work on go kart because they have the same amount of space as the discs on the bike. Not like the ones some zanardi go karts have.

 

[mckutzy]

I dont see those big 6 working with those smaller 4 piston rotors.
The hub for the big rotors are as big as the OD of the small rotors.

 

[itsid]

oh my...
there's a reason those 6piston calipers are mounted to huge discs..

it's called HEAT DISSIPATION;
the disc needs a chance to cool down slightly, else it will just soften because of the friction heat
from the caliper.

So, either you must install 12" discs to use the 6 piston calipers, or you must install smaller but internally cooled discs, and modify the calipers by adding an extension to fit the much wider brake disc.

In fact, since the wheel is so small.. the disc will turn much faster than on the motorcycle (that's per mph of road speed)
sooo chances are it will need to be cooled anyways.

A smaller caliper heats up a smaller portion of the disc of course, thus the cooling time is bigger

choose wisely!

Okay then I think I will stick with the kit then.

Nope not me. I just joined this site about a month ago.

 

[x5050160]

Another thing to think of is the braking (friction) coefficient needed as to the weight/speed of the kart. You need sufficent brake power to slow or stop the kart. But bigger is not always the best case. Sure bigger rotors and pads will work more efficiently but if they are too big all they will do is lock up the wheel. The friction coefficient between the tire and the surface it is rolling on should only be overcome at or past 85% - 90% brake input. You don't want to have such a powerful brake system that the wheels lock up with only 25% brake input.
Also you might want to run a brake bias valve to adjust between front and rear brake power. You have way to many variables in this to have the proper balance even with an engineered system, and you are talking about just throwing something together.

Be safe

 

[KlaudioP]

Yeah
I'm going to tried and tested ones front and rears and if that doesn't work then I will put on a parachute as well.

 

[mckutzy]

Wow..... Kinda in one ear and out the other.... Did you even listen to what is being said....

Howabout some wings while your at it....

IBTL....

 

[Zombient]

I'm done.
