Hi!

Can you tell me more info on your C11?
Does it performs like a Flash or more like an 35Plus21?
Did you ever try it with nova2015 or picco2033 pipe?

Regards!

The c11 is better than flash and 35plus21 ,I'm using rb 2018pipe or rb 2092 it perform close to the nova keep on ,best is to use o'donnell 99plug or os RP7 ,infect the new cxr is the same as the c11 only different is the sleeve got 2 more tiny port below the exhaust port for more cooling but it makes no different to me , heat sink different only the wording, i have both cxr n c11 love both of them check it out at amainhobby they are offering rb now with c11 at usd $399 at this price u can out run most others race engine. don't get the cx it a waste of time as the crankshalf is not balance, not hard coated on crank pin no silicon paste plus no ceramic bearing not worth the price u paying for

But the big problem is it is not using R7 conrod, RB conrod is hard to find and relatively expensive

Default Novarossi keep-on engine

I'm currently running a Team edition novarossi keep-on and it's more powerful than the other two engines mentioned...

haha true, RB engines were amazing though! I'd still run them over any other brand if they were still being made.

How good is your driving?

If you do need that last tenth of a seccond to become a world champion then yes, Ceramics can help. If you are far from that you can better spend the money on spare parts to keep that car running.

The standard RB CX (2012 engine) is just as fast as the RB CXR (2012 engine). The only difference is the counterweights in the crank shaft, the exhaust, transfer and crank timings are identical between the two models, the CX is a very good engine based on the Novarossi Flash PT/35 Plus 21 era of engines.

The RB CXR SLS DI9, CXR SLSV2 which were the longer stroke design were fantastic, tonnes of power through out the entire power band, these were based on the Novarossi Keep-on and were immense engines.

RB pistons were cut from billet where as Novarossi were made using microcasting, the reliability of RB engines was fantastic, as was the performance.

Very good engines!
