I live In Bermuda and run the P3. I figure your climate is about the same.

Neil, what is you thought about this engine compared to some of the other brand race engines?
I'm in for some new engines and would like some inputs from you.
Currently running REDS R5T and like it but my LHS doesn't carry them or spares and that is the reason I'm looking for different brands.

This engine is likely much like a R5T...smooth but strong bottom and a powerband that picks up steam the higher in the RPM it goes.I have not run this engine other then on the dyno and its still quite new ..plus the one tester we have has a damaged piston after dyno testing and we are still waiting for repair parts... I repaired the piston as best I could and so far the engine is a good runner, but not 100% reliable...The repair parts just became available so it shouldn't take too long till I have some better feedback

Hello rc pete,
I have been running 3 litres of Fuel on the Spec III. I hope, really hope the mileage will be improving because I really love the Power Band.
Cheerss..

Maxima Mx Europa
Maxima Mx Europa Nigel Winkley Maxima Mx B4 is the successor of Mx B2R, the engine is based on the new O.S Speed 21XZ-B spec. III and itīs power characteristics are sort in between Spec II and B2101. Overall itīs easier to access the right powerband and the Runtime remains very optimized as all Mx Engines, more than an "standard" engine.

I saw a few Spec III's this weekend at the Southern Nats and the engines ran awesome. I will be ordering mines today.

I was there with mine.. The top end was good.. I didn't see any others than mine. I must have missed them sure wish I could have talked to the other people with them.

Yeah there were 2 guys sitting by us and 1 guy by the Indy RC trailer. We were to the right as you walked in, 3 to 4 tables behind Victor Guerrero, Ty and Gordan Tessman.
