Hi Austen,
Use 13k max for the CBR and 13,750 for the R1. The R1 is better suited for your 3.54 live axle - it should be good for around 135 which is fine for
any track we race on. The CBR is the stronger motor (especially in the midrange) so would be the motor of choice if you were independent rear.
However, your car will still go like stink with the newer R1.
Cheers
Paul

Cheers paul, I'd come to the conclusion the r1 was slightly better suited to the live axle, its just the height of it which I a pain in the
fury. The thought of an extra 50bhp in my little white bumper car is pretty terrifying!

In reality its more like 30hp at the wheels, but still nice to have nonetheless! If there are enough people going R1 maybe there is scope for Mr Bates
to do a custom airbox to reduce the airbox height?
Dump the variable height trumpets and relocate the secondary injectors and you could reduce the bonnet bulge quite significantly I'd guess.

That should be exciting enough to warrant your own AMTV clips show!
