Animal Racing Engine Discussion

What are the slide opening gaps for the Blue Slide and the Black Slide?? I am looking to make some "no go" slide tools out of drill stock.

Breaking the exhaust fasteners is a result of improper exhaust bracing, gasket crushing, and/or installing the system in a ‘bind’. Most aftermarket exhaust designs place excessive weight on the exhaust fasteners. A low cost insufficient bracket and a hose clamp do not prevent the vibration and weight. I can’t tell what gasket you run but graph-oil gaskets and even copper, when the exhaust loosens, will pound the gasket to the point it crushes and the entire force again goes against the fasteners. Lastly, when you install any exhaust you need to make sure when tightened down that the system is evenly torqued and bracketed. If you are ‘forcing’ the bracket or exhaust in place all of this stress will load on two fasteners not designed for shear strength. The things to do to help prevent this: - Make sure your exhaust isn’t put into a bind. - Improve your bracing. GOOD, working systems have multiple bracing points AND better clamps. Hose clamps break and by the time you discover it, it’s too late. There are many systems out there, I would use the dealer locator on our site to find someone in your area to work with. - Check your exhaust fasteners after every session and use safety wire to prevent them from backing out.

what kind of speed and acceleration could you expect in a go Kart with this engine?

Asked by: TerryL
This depends on the track layout because that will determine your gear ratio. Your gear ratio will determine your top speed as well as your acceleration out of a corner.

Why doesn't your engine specs list horsepower

I've been trying to compare your engines and others and without horsepower ratings that makes it hard to decide when you can plainly see it from other manufactures. Thanks Clay
Asked by: Clay
Due to a change in industry rating standards we now rate the engines by using torque to describe the engine's output and capability. Gross torque is a more direct way to measure the turning force an engine can produce.
