I haven't. I posted the numbers I was told to me. And people were upset with me. So I'm not going to repeat them. You can probably contact Rod Bloomer on Facebook and he can tell you. But I can say with confidence that they make an honest 680hp and that's with only 11.2 to 1 compression. The car has been 116.6 mph in the 8th mile, at a weight of 2879 lbs. That includes the driver.
