I think you may be off a couple decimal points.
It really only becomes a problem when approaching relativistic speeds.
Thou shalt not add my speed to the speed of light.

but its not likes its gona pull some top fuel like burnout

I'm not building a dragster.

We are talking about 2 lawn boy 2 stroke reed port engines rated for 6.5hp@3600 RPM, they are now running around double the RPM with upgraded exhaust on a ~100lb kart with narrow tires.

My 200lb manco with a little weak briggs 5hp and Carlisle 21x12-8 knobbies would push my 200lb behind back in the seat and bottom out the front suspension when I engaged the throttle, the tires would skip half a turn in dry grass and it would pull dougnuts in loose stuff. This thing will not hook up well.

find some bigger tires lol, i think this smog pump setup im making is going to make a lot of horse power maybe another 5 before the whole thing explodes lol, i think it would be safer to find two moters and gear them together
