speed question

[r97]

i was fidling around with the calculator and found out somthing. if you get a tc you can have the final drive rateo be 2 to 1 and hit 72. then have a low end of 6 to 1, which wont burn the tires but will get you up to speed. although you can do this DONT!, like kaptain said "I can hit over 70...however i would have to be insane." and by the way bike spedoes are good for karts

2:1? I don't think that's going to happen. Plus, dunno which TC you're referring to, but the Comet 40 low range is around 2.43:1. So with a 2:1 final, low range would be 4.86:1, which certainly wouldn't be anything to write home about in terms of launch. Based on my own experience, I really don't think that 2:1 final drive ratio is an option...

If you had 10" race slicks, and a flat road. 4.86:1 isnt horrible, and you would probably get moving. but for anything but asphalt and race karts, its not gonna happen.

Enough antifreeze on the pavement and anything will burn em.

I've been wondering about a spedometer for my kart actually. I want a gauge though. Is there any way I could go about doing that, and have an acurate reading? I was thinking a wrecked motorcycle gauge, but I don't know how to set that up for a lawn mower tire, instead of a bike tire.

motorcycle speedos are generally cable driven, and it would require a custom gearbox and a little math for it to work properly with mower tires. A digital bicycle speedo would work fine tho. there wicked cheap on ebay.

Do you see any with a big, or maybe backlit screens?

And how do I set them up?

i mean 70k not miles and im not worried about fliping my kart that im building is wide and i have desided to use a lot bigger tires 19 inch diameter and im looking for top speed now i know my motor wont burn these tires

i could easily hit 50 there, but stopping in time for road crossing is another thing haha.

ha lol alway a thrill to go fast
doesnt half make a tense monent trying to stop before impending danger
