Dodge, I feel for you. No tech at a track will always cause problems. I'm the tech director at our local track ( director, not inspector ). I'm also a racer. I'm fairly fast but at age 67 I don't expect to be as fast as the top flight racers in our class. I can put one of these guys in my kart and with no other changes they will be 1 sec. faster. ( sprint track) Do I suspect your competition may be illegal? Perhaps, but with no tech we'll never know. Lots to be considered. We do tech very thoroughly at our track, everyone has the same engine, most are blueprinted ( World Formula ), it is very common for a right out of the box engine to win over bp'd engines. That is why I hesitate to say someone's engine may not be legal. Last year we had a 16 yr. old driver with a ton of racing experience start racing with us and no one could come within .5 sec of him. EVERYONE KNEW he must be cheating. I sold him the engine new, installed it on the kart and they never touched it! Always passes tech. Sold the entire operation to another guy and it became the slowest kart at the track!! The LO206 is very easy to tech. If nothing else the individuals should submit to tech at the season's last race. If not, REVOLUTION !!!! Ha!
