Re: Racing Go-Kart Project
The Coyote is a real chassis. One of the very few US made. It's specific to circle track but will work for a drag kart. They don't make front brake kits for the Coyote and with a Briggs you won't need them. A new front brake system is about a grand, plus whatever you need to do the the spindles to accept the calipers.
As for the the Briggs, great supporter of karting but in comparison to other formulas isn't going to come anywhere close to that sort of acceleration and some of them won't do 60 mph at all. A clutch kart won't hook up fast enough to come anywhere near your bench mark. It could be fun though. And cheap. Those are only 8-10 hp engines even with the most extreme mods. Depending on the clutch you'll be lucky to hit 60 in under 10 secs.
That package is better suited to circle track racing. You'll have a lot more fun than if you tried to drag race it. You should be able to finish that kart off with a new Briggs for $1200 or so. The engine will be 600-700, tires a couple hun and some misc hardware. Get a kart suit, neck collar, glove and a good helmet.
