Some might say that pipe design is not Rocket Science, but it might as well be. It takes 4 minutes for a modern PC processor just to simulate a 1 second real time event...that’s a ton of data. Were all about data. If the data doesn’t support it, it wont happen...period.
Goal: create the hardest hitting, max tq. and HP inframes for the CP Industries Cheetah Cub. These cylinders in stock form are by no doubt the most mathematically correct designs on the market. They have great potential for additional HP as well with extra porting and mods. All the version of it are similar and predictable when modified. In creating this pipe we needed a correct design to base it on. Good math in, good predictability of our pipe in the design phase.
Not all engines run best with a certain pipe. But choose a category specific engine style in the design process, and the results are much better. Its also easier to tune the pipe for a certain engine type.
Our pipe was designed on the 421 cc Cheetah Cub but will also run well on others as well up to around 600cc. Once we are fully tooled for production, I will place a port mapping guideline on my website for a tool for people to use to calculate a few things before contacting us to see if this pipe might work for them. We also have tunability of the pipe capability in pre-production to custom tune it for your engine based on you port mapping specs you provide based on the guidelines on my website.
It will be offered in our standard form for gas and methanol, along with custom tuned versions discussed above.
Some OEM cylinder porting designs will be able to use it as well. Im quite familiar with most of the major engine builders designs and some of them will fall into the correct engine specification needed for best results. Regardless, the mapping guidelines I will offer will be the last word...its that math thing again, you cant get around it. Real science makes real results.
Our first stampings are finally in and I have a few pics and a dyno run against a very good pipe offered on the market currently. We hope to be in full production be end of summer.
Special attention to physical design was based on input from my customers over the years. GOOD body english, no hitting the frame, head, carbs. You can run the stock air box, it clears the bigger cylinders. It has good plug access, and yes, it even clears a Pingle. Welcome to the new standard. Point em’ out, and take em’ down SNIPER PIPES....Jim Smart PASSION RACING ENGINES
