The .12 CV isnt the fastest engine out there, but you will probably find that you will be faster around a track with a CV than a CV-R. Too much power for you will cause you to make costly errors, the CV will help you develop your driving skills.
But if you are racing I am sure people are run more powerful engines then the CV. OS makes great engines, easy to tune, hold a tune, and very reliable. For the money you cannot beat an OS! They all so are known for very conservative on there claimed HP which means they are normally more HP then there claim. The CV with the square head claimed HP .56, CV-R 1 HP. I agree fast engine is not the only thing that wins races. Driving ability is just as important. [8D]
