One of our more popular l talk about some great ways to extract more horsepower from a gasoline powered small engine. Everybody with a mini bike, go kart or other motors want to get as much horsepower as possible!
Some of the most popular small engines for mini bikes and go karts are the Predator 212, and the Predator 420 or the Predator 670cc. What is your favorite?
These gasoline powered small engines are all copies or “clones” of a previously produced Honda motors. Honda motors and the clones are very popular for mini bikes, go karts and every tool you can imagine. The motors are very well designed and virtually bulletproof. Making a great platform for making more horsepower.
We get asked the question quite often “How do you make a 212 cc predator go faster?”
There are many modifications you can make to increase the horsepower of a small engine.
Small engines need three things: air, fuel and spark. In this case we are going to talk about a predator 212 exhaust.
“When you add more air and fuel into an engine, you get more torque and horsepower, which is the cheapest bang for your buck .https://kartfab.com/go-kart-engines-predator-212cc”
“The stock exhaust is very restrictive. After seeing the inside of a stock muffler, we were surprised our 6.5 hp Honda could even run with the stock exhaust. Upgrading to a high flow header is a big performance enhancement. https://affordablegokarts.com/pages/performance-basics”
One of the most popular methods is increasing the amount of fair and fuel mixture introduced into the combustion chamber. Anyone that has tried to gain horsepower from a gasoline engine knows the saying, “Gasoline engines are a pump, more fuel and air in, more power out” right?
For our purpose of gaining more horsepower from a gasoline small engine we will focus on the exhaust flow.
Just increasing the flow is not the priority but maximizing the efficiency of the exhaust flow has produced the best results in our dyno tests of Predator 212 cc engines.
