Want to thank you for the great engines and tuning advice that you provided our team. Nicholas had a great year winning 9 races, including the year end 25 lap race at Snydersville Raceway. Alison also had a great season winning in the Kid Kart Rookies at Snydersville and winning again at Shellhammers Speedway in her first year of racing.

Hi Mark,

Just wanted to drop you a note and thank you once again for all your help this year. The engine work you provided us was flawless and made my job much easier. Miles won 10 feature races this year and won the Rookie Kid Kart Championship at King George Speedway. We are looking forward to running the unrestricted class next year using the strong motor you provided.

Have a safe and happy holiday season.

Thanks for all your help again

Lucas has won 2 races at Homestead Karting with the help of your B.R.E. blueprint engine! Not only did he win both races by quite a lead, but the engine passed tech without a hitch! This is also Lucas' first season participating in the FCKS Series in Florida. He placed third in the last race in Orlando, again with the B.R.E. engine!

Your customer service is incredible ... Thank you for all your help!

Other Services and Trick Items

We are hesitant to list these services and items because too many racers will just start buying the single "hot" item that they think will solve their particular problem or propel them to the front. Kart racing does not work that way. The real trick is to make sure ALL of the basics are spot on and to tune and match things up so that every part of the kart is working in harmony with the other parts...including the driver. Please call with your particular challenge so that we can help you solve it in the most practical way without wasting your money on things you don't really need.

Notes About Engine Blueprinting

Here's my take on our blueprinted engines. Unless requested otherwise, I build my "blueprinted" engines to be LEGAL at the Kid Kart Nationals. This is the strictest kid kart engine rule set that I am aware of. I will never make claims like "our blueprinted engines are the quickest, or are hand picked from select serial numbers" or anything like that. What we do is build a solid engine that goes right up to the limits without going over them. They are engines that a competent technical inspector will do a thorough inspection on and still pass. They are meant to be a solid foundation for a kid kart race team. To be successful with these engines the racer will have to learn to tune the engine for varying atmospheric conditions (To help with that read this.) The racer also needs to realize that everything on the kart must be aligned and set-up right to compliment the engine.

One might think that all they need to be "legal" is buy a new engine, take it out of the box and assume it's ok. The truth is, there is very good chance that the engine is not legal according to the rules. In the past year, almost every new engine that I have built had at least one technical inspection item that would not have passed a legitimate inspection. There are a lot of good running "legal" engines being beat by engines that are coming right out of the box. There is probably nothing wrong with the legal engines but there is a really good chance that the combustion chamber cc are too low, and igniton timing too advanced, items that make a huge difference, in those engines that have not been blueprinted.
