In my humble opinion you need to add head shim to any engine as need for the barometric pressure, humidity and outside temp.This will change every weekend as the temp and pressure change thoughout the days..plug heat range is another way to change the time at which the combustion will occure
I like to use the head shims to control temp in the motor and plug ranges to help with keeping the mixture where i like it [lean helps with top end rpm and not power] a hot lean engine will not make power when exiting a turn
Another though too consider is there are many turn and only one straightaway
Gary you are the man.when i see you at the track i'll need to use some of that knowledge.

been looking at getting one of the xl9 engines. It was suggested to replace the ceramic bearing with a steel bearing. does anyone have the part number for a steel rear bearing from Max? Or the size of the bearing so I can order from someone else?

Here is a good one but I would stick with the ceramic.

Default Australian Nitro Nationals

Hey guys, just thought I would let you know that 16yr old Ryan Maker has just Qualified and finished 2nd at the Australian Nitro Nats with a MAX .12 XXL B. Was just 1 second off TQ after the fastest 10 Min qualifier.
Also set Lap Record!!
The motor was nothing short of BALLISTIC and had legs all the way to the moon. Was very easy to tune also. Can`t recommend this motor enough to anyone wanting serious race winning horse-power!
