Does anyone know if the RS91HR will have the same piston and liner as the RS91 engine? :blink: Is there any likelyhood that there will be a 101HR engine further down the track? B)

Is CMB91HR more powerful than CMB91(EVO) RS or CMB101RS? :huh:Ian, bore 27mm and stroke 26mm and ABC.
3 post config (1 boost 2 transfer) and 1 exhaust.

There are alot of nice shots of that race, thanks Ian. Also what kind of heat speeds are you guys running & what are being used for muffled tuned pipes? There are alot of boats there running the same engines as US boats & finding some info out on what muffled pipes you all are having good results with would be greatly beneficial to those of us here in the States who'd rather find a way to get under the new noise limits than just ***** about it......New Motor wins its first race in Sweden

Haven't measured mine yet, but it appears to be the same size rod as the 67/80 , but longer. Small wrist pin and crankpin. 27/25mm = 1.08 bore/stroke ratioA few technical questions for Anders or those who have had the new engines apart:
-Do they have 6mm wrist pins like CMB/MAC 67/80/84's, Rossi 90's etc or 7mm wristpins like the CMB EVO/RS 90/91/100/101's?
-Is the rod centre distance 45mm?
-What is crank pin size? Does it have a rod bottom end like the CMB/MAC 67/80/84's or like the the CMB EVO/RS 90/91/100/101's? :huh:
