A buddy of mine wants to start karting and he was curious, (so am I now), about are PRD Fireball motors need as much matienece as a rotax or does it need more? If they are pretty descent then I might just have to make a comeback to racing

I use Doug Flemming of Flemming racing engines. He builds horsepower cheap and reliable. I would never allow for scribs to build me a racing motor, unless it was a shifter motor or something like that... They just don't have the experience.

Yeah I wouldn't go there even if I drove shifters.

Nice to see an influx of people wanting to use the PRD motors ...these engines will handle about 25-30 hours of use before they need a rebuild - so if looking to buy used be cautious of the hours on the engine.
The fast guys blueprint the throttle body to get a bit more of an quicker throttle response out of the engine which definitely helps on the larger straights that are in so-cal if you want to try a different track from time to time. And you can see a difference between the non-blueprinted and blueprinted guys in lap time differences so its something to factor in eventually. Whats nice about these engines is if you blow one - god forbid right...you can pick up a new engine, radiator, pipe, and all necessary wiring for around 1600 from RLV - compare that with a Rotax and you can get 2 PRD's for the price of one Rotax before any sort of blue printing...
The engines are very much a "spec" motor and do have specific IKF rules that everyone follows for rebuilding them when it comes to seals, bearings, pistons, and the ignition - you will have to look at the IKF sight to see the specific rules, as this club and other clubs in So-Cal follow these specific rules.
The really good PRD Senior drivers rival some of the Rotax drivers for lap times up at Cal-Speed during LAKC and Tri-C club races so don't think these engines wont have capabilities BUT I don't recommend them for the general TAG class against engines from Rok-TT or a solid Leopard based engine which just seem to make more power. a Good PRD engine once blue printed should hit around 15300-800 RPM on the big straights (depends on gearing and length of the main straight)
The better engine builders for the PRD engines are typically Mike Manning Karting, I think Swedetech (big in the shifter kart world) is doing them I think now, P1 Engines is another good builder if you want to go that route as well, not sure of anyone locally
Hope that helps
