Supercharged AKN

[Tyson Anderson]

I kinda thought 40k might be easy to accomplish but I have never built a go kart so I don't know what to expect. How many horses do you think I will need to pull a wheelie? lol

How do I add pictures from the camera on my phone?

My bike does 65kph at least... 75 gearing wise....
Check my bike you'll see why...
40 it's good to go with your current setup no blower... Just NA.

Wheelies need big torque, a light frame, and the majority of the weight on or behind the back axle.

20 hp with a torque converter, and the right gearing and tires would probably get your front wheels off the ground, but you need the raw grunt of low end torque you can only get from a big engine.

Look at kartfabs pages. He has a dingo that does wheelies. It took a bunch to get it to do that. Hp and low gearing.

Pics of the beast

These are the pictures I have of th engine

Although it's a bit more complicated than this, to get the kind of power you're looking for (10+hp from a 6.5hp engine), you'd need to shove at least 2/3 more air and fuel through the engine, which means 10psi of boost, minimum. To do that, you'll need a substantially larger carburetor.

You actually don't need a lot of carburetor for a blow-through setup because the compressor is making the air so much denser. If the carb is properly sized for the NA engine power, it's going to be fine for blow-through.

Draw-through is different; there is only atmospheric pressure to push air through the carb. It needs to be sized for minimal restriction like an NA engine would require.

I did not think this would be easy but hopefully I can do it cheaply

Yeah.....not likely.

My suggestion would be to get the engine on a kart, get it tuned and running, and see where you end up....Then start thinking about more serious mods.

If you really think you want to pursue supercharging, then get the engine making as much power as you can on the stock compression. Boost is a power multiplier; the more power you start with, the more you end up with.

Add 15psi to a 6hp engine and you might get 12hp. Add 15psi to a 12hp engine and you might end up with 24hp. Big difference.

Project update

Ok, ive been working on the kart and havent given you guys an update for a while so heres the rundown:
-engine is done and running like a champ it has a new bigger, better carb and has been given a paint job
-I decided to go with a torque converter. It is already mounted on the engine
- i got my complete frame done with a seat and steering aseembly
-the engine ine mount is on
- the rear axle and all the wheels are on

What i have left to do:
-put on seatbelt
- attach steering wheel and shaft
- weld on sprocket and brake disc
- mount engine
- run throttle and brake cables

Here are some pictures:

It’s definitely a unique cart

Well good thing it wasn't supercharged. I would not recommend modifying that old engine unless you want to destroy it. There's a reason you don't really see anybody riding around with boosted go karts.

You are definitely right, i think i will be happy if i get the whole cart working good
