More info on the tractor from Jr.
It’s a cat 3406b from a foden 4000 truck, 14.6 litre and is currently running about 500bhp with uprated fuel pump and injectors. When the turbo blows it’ll be replaced with a much bigger one from the states as the engine is very popular over there in truck of the 90’s and are regularly tuned to 7-800 bhp for normal use and can see over 1000bhp with uprated internals!!
