November 20, 20196 yr #1 I have a BF XR6 and the motor is in very bad shape. I have a greenhead gas Barra that I pulled out of a BF, if I ran that on petrol, would it be slower?? Or faster??? I know the gas Barra has higher compression but with the more heavy duty rods will my power output be less? And no I can’t turbo it because I’m on my Ps lol.
November 20, 20196 yr #2 it'll be as fast as it gets tuned to be... as it'll need tuning. definitely more efficient with the higher compression but that won't necessarily be the best situation for power generation unless the tune makes more power.
