I’m in a high school auto class and each class had to make a go cart to drag race against the other classes. The only cache was that we had to all use the same power plant (One kid had a Honda motorcycle engine from a cop bike). My class made the whole thing and we thought we hade it down good. But then we saw the others. They were almost all the same! The next Monday we went to work lightening it. we took 45lbs of it and adapted a transmission from a old Honda(I think) to free up hp. then some kids grandfather told use how to put a blower on it.
Step 1: Find a 3-6psi air pump from car or truck (it’s for smog control)
Step 2: take carb apart and make hole bigger on jet (or jets) we used a 1mm dill bit (I know this sounds big but we are drag racing it)
Step 3: weld pulley in to a drive shaft or something that spins.
Step 4: weld the pump in line with the pulley make sure it is strong (we first one broke, I had to weld the next one
)
Step 5: bye a belt and install it make sure it fits well.
Step 6: make box that an air filter will fit in and run 3/4 in pvc pipe from it to the blowers inlet side. The same to the carb from the out let.
You might won’t a bigger fuel tank.
We added 12mph onto our average and got 3psi of boost
