Advice on building my own race cart chassis

[DIYbuggy]

i want to find help or plans to build my own race cart chassis. any help would be appreciated. thanks guys

Right now I am not aware of any racing frame plans, as with most manufactures, their chassis plans are a highly guarded secret. Here in the USA, most racing go tracks use a mixture of WKA/IKF rules along with there own rules. If you are planing on racing at a sanctioned track, I would get a copy of there general rules and a copy of the class rules you plan on running in. As there are certain wheel base requirements along with engine rules and etc. Outlaw racing tracks are mostly RWYB. Racing kart manufactures spend a lot of time r and ding their karts for flex and etc. I think if you plan on racing, I get a used racing kart frame and go from there. Of course if you have a Buddy thats into racing you could always borrow his/hers kart and reverse engineer it.

There are one or two plan sets available but, whether they'd be sanctioned by any racing body is another thing.

Tell us a bit more about what you want & what you plan to do with it...

im basically looking for a yard kart with the same characteristics as a racing kart. and i figured that if i design my own chassis i could actually get legal rights to the design. i may use it in the future to race though. depends on all of the rules and stuff.

I would like to see where this goes.

The only problem is that the rules are updated every few years so, building one frame won't fit the rules for too long...

There are one or two free plans available such as this one

Yard karts & race karts have little in common. The guys who build race chassis have a lot of time, money, & experience invested in their product. Odds that you can duplicate that on your own without any of those 3 things anytime soon are very slim. These guys don't buy their steel at the local recycle yard, either. If you want to race you will be better off buying a chassis, new or used. If, on the other hand you want to incorporate some race chassis ideas on a yard kart you probably could but keep in mind a yard kart is a straight rail chassis, a race chassis (unless it's a vintage racer) isn't.

well i have alot of welding experience and am an active CAD designer and im pretty confident in my abilities. i have access to a full automotive work shop with all welders,benders, and everything else used in clean building projects. and i would not be using a scrap yard as a steel supply, i would be using a world retailer for my steel needs. im actually very confident in the actual building part. i am looking more for complete dimensions for building a race kart chassis that i would be using to implement ideas for kart racing. i am an aspiring engineer. so if anyone has any information i would love to be able to see/read, to obtain it.

Being an engineer(of sorts), I understand wanting to do something and not knowing how to go bouts designing the idea. My perfect example is the rearend and the swapping of a 2 seater to a 1 seater, on one of my karts. Instead of completely fabricating and designing and constructing what I had in mind... I improvised and designed an 'already' constructed idea(3 karts fused into 1 frame). I later thought bout building from 'scratch'... but decided that custom prefab design was good enough for my needs/wants(not like all my ideas are original... just slightly slanted in construction).

IMHO, I would 'find' a prefabbed frame and work from there. By doing so, youll learn the in's and out's of karts/gears/laws of .../and in the meantime be able to build around the 'rules' of the racing kart industry.

Im by NO means a racer(on karts) and my OCD of symmetry wont allow me to voluntarily get a 'race' kart... but my 'design' of my kart allows 'some' rules of yard karts, to be modded for my personal preferences.

... I know 'race' karts are REALLY low and wide...

DIYbuggy,
I don't know of any good building plans, but here's some dimensions from a 1999, Beisse B3 sprintkart.
You'll find more pics/info in this thread: http://www.diygokarts.com/vb/showthread.php?t=3664

The Chomoly frame rails have a 33mm. diameter, with a 3mm. wall thickness.
