Pretty sure the ratchet or pop-off device aren't required unless you run faster than 10 seconds, it may even be faster than 9 seconds. You can find that info on the SDBA website or rulebook. Hey Kevin, thanks again for the shirts and you know I will help you any way I can. Hey Liberator, any idea how fast your boat is? David, you might as well come on down, too. We'll have both out blown alky Placecraft's there, as well as the rest of the herd. How about that 7.79 in the Place jet. That's the boat that all the guru's told me we'd never make run faster than 9 seconds with the lakeboat hardware. That was with a 4.30 1/8th mile E.T.
