Wood is for camp fires.
8mph is the fastest I would dare go on anything made out of wood

6x6" + 6x6" with a dovetail mortise and wedge block. 6,000lbs before it pulls out. Fiberglass rods with a roughed up surface [for maximum surface area] epoxied in. 40,000lbs.
you can also look up the super car the splinter for good ideas.
Any kit aircraft that uses wooden ribbing.
and any boat building.
Lots will disagree and tell you not to build a wooden kart on this forum, its just how it is. but if you understand that your basic 2x4s and pallet wood and some drywall screws aren't going to work out in your favor, you're on a good start.

That's the problem. Most people who want to build wooden karts do not even have that knowledge

I would go as far as changing "most" to "virtually ALL" people who want to build wooden go karts do not even have that knowlege and the only reason they want to make a wooden kart is because they lack the tools and knowledge to make a real one in the first place.

From an engineering standpoint, mild steel is a very cost-effective and structurally sound material to use for building a go-kart.
In particular: mild steel tubing is cheap, very tough (resists fatigue well), and ductile (easy to form). The ductile nature of mild steel means that it will bend before it breaks, giving you an indication that something is wrong without causing you to suddenly crash. The tools required to work with mild steel tubing are very cheap, as KartFab has demonstrated in his series of videos on how to build a simple go-kart, beginning with this one:

Conversely, while it is possible to build a go-kart from wood, it is a poor choice of materials for that application. If you must use wood, you'll need to get the engineering correct, because wood is prone to fracture suddenly and catastrophically. You will also need to be a very accomplished wood craftsmen to produce tight joints which are structurally sound. In short, if you don't feel like you could build a wooden airplane, you probably shouldn't build a wooden go-kart.

Depends on if you want to get a good welder or not.
Can get a cheap AC stick or AC fluxcore welder for for around $100 bucks if you go Harbor Freight's Chicago Electric. They operate off a normal 120V 20 AMP circuit. The flux core wire from Harbor Freight is crap so replace it with Lincoln wire if you go flux core.
got the HF 90 Amp AC fluxcore (120V, 20 Amp -NO MIG set up). I had an experienced welder help show me how to use it. He seems confident that its good enough to repair frame work and such. If you learn how to use it, Im sure it will work to build a frame. Probably hard to use for anything thinner than 16 gauge
Welder (up to $500) $100
Harbor Freight welding mask $50
Files and Brushes $10
Gloves $5
Lincoln Wire $10
Angle Grinder $20
Cutoff wheels/grinding whls $10
Just over $200 can get you started.

Either math is wrong, you inputted incorrect values, or its geared wrong (or tiny tires). Im guessing the inputs are wrong.
MPH= (rpm/336)*((#ClutchTeeth*RearTireDiamInches)/#AxleTeeth)
EXAMPLE:
RPM = 3600
#CLUTCH TEETH = 12
#AXLE TEETH= 72
RearTireDiameter = 16"
MPH =
(3600/336)*((12*16)/72) =
28.6 MPH
