I've never dynoed mine- but did build mine the way Bob K. suggested- he's a heck of a nice guy- I ran my A-12 Bee at BIR last fall- 6 passes, with a stir stick, 4.10's, repop redlines. Now granted I have never raced one of my cars before- so crappy reaction times, and couldn't hook it up for diddly- I ran very low 13's at 103mph. It idles like a slant six, starts great, and tears it up plenty for me- but I'm obviously not a racer- just did it on an open night for the heck of it-
