| it on the chassis dyno there, along with my Buick. I will run the Buick before & after the motor changes, to see how much h.p. I have gained. I have hesitated taking the Bentley up to be tested before now, as I didn't want to take a chance of "blowing up" the motor by running it wide open on power tests. As I will bring it back to England, however, I guess I will risk it this year. Of course, the Buick motor is much larger than the Bentley, and has considerably more torque at low engine r.p.m. This helps acceleration. Well, thanks again for all the interesting information, and please send along the Bentley test report! Most sincerely, Briggs Cunningham | ||
