The T9 and T10 have a bit more topend because of the higher exhaust port.
If I'm correct the T10RC also has a balanced crankshaft.
But an R3 would still be very competitive, actually my fastest engine (and probably the fastest of our entire class) is an R3RC from 2007.
It has done 11 litre's thus far but still locks up while starting if it hasn't been pre-heated.
It's around 5km/h faster on the main straight as any other modded motor, including Murnan's.
