So far, it goes 12-flat/112 mph on 15 pounds; 20's gotta be faster than that.... or..... BOOM!!! LOL!
Guess I'll find out when the strip opens.... I ran a compression check and all cylinders are between 160-165, so, it's not "hurt" yet.... (with good oil pressure and no bearing noise.):D
Thanks for the interest, and the birthday greetings!
