RB B10
 

Chaps,

is anyone running one of these engines?

How do you find it?

Do they still cut after refuelling? (sorry for generalisation)

Best pipe for it??

Can i expect 10min runtimes....

Anyone running 30% fuel on them?

sorry for questions but i have seen one for a good price and i used to love rb until things went tits up:D

The B10 is a great running engine and plenty of power for a buggy or a truggy. The cutting out after refuel is an issue that is more tuning and spilling fuel. If your pit guy spills fuel you are probably going to die. If your engine dies after getting fueled, with no spillage you are not tuned properly and most likely rich on the LSN. Some people will run a hotter plug which works but it is just masking an incorrect tune in the long run. The B10 makes good power down low so it's easy to have the LSN set rich and still feel good power. I have run 20% 30% 40% and 50% thru a B10 with no issues at all but I race at 6,500 feet, to run more than 30% you may want to add a head shim. As for the 10 minute run times... It is possible as I have done it in both buggy and truggy but there is so many factors in this and the driver the biggest so everyone will be different. As for pipes I have used the 2045 most of the time as that pipe will smooth out the power and make it driveable. The 2013 pipe works great, as does the 2084 Nova pipe and the 9901. If you really need bottom end the RB 2020 will be the ticket. Since it seems your looking for run time I would suggest the 2045.
