New project!! And it’s not what you’d think or expect....BUT ITS GONNA BE A BLAST!! ~
Engines are engines. The principals of building horsepower are the same no matter the application. Increase the cylinder pressure and you increase power output. Period. That philosophy led to this endeavor.
I’ve always wanted a pit bike to ride around at races or car shows and now I have one! A Coleman CT200U-EX. It comes stock with a 6.5 hp 196cc “Honda Clone” powerplant that works admirably for the normal person. But in true gearhead fashion......anything worth doing is worth overdoing.......so.....I bought a spare bullet for it that I am going to extensively modify. These little engines are available at a bunch of places and have very strong aftermarket support for making more horsepower. This particular one is the “Hemi” headed version. I’m going to build this one up with the same attention to detail as any other race engine I do: Careful measurement, documentation, accurate machining, application-specific parts, meticulous assembly, and ultimately testing. It will still be NATURALLY ASPIRATED 💪🏻👊🏻. The easy route is to put on a mini turbo or spray the nitrous to it. Not this one! The object is to see what it will take for rpm and power output with proper parts. Allegedly people can get 30-plus hp out of this 12.92 cubic inch mill 🤔.
I do think that 2 hp/ci is very possible with great induction, big compression, stable valvetrain, and higher rpm. Sound familiar?? That’s the same formula for any high specific output bullet. I’ll post updates as they happen. I’m really looking forward to working on this! Remember you can always learn something that applies somewhere else if you pay attention. This will be an economical research project that will be super fun to ride, as well!! #engineguy #enginegeek #enginebuilder #enginebuilding #tvhost #gearhead #ilovecylinderpressure #naturallyaspirated #itsscience #knowledgeispower #attentiontodetail #learntolearn #highrpm #voidthewarranty #minibike #pitbike #racebullet #prostocktechnology #builditrightandwindittight #topolinskiranch
