Gotta love the haters! Apparently they cannot fathom the idea of something new becoming more and more popular. The initial cost is high but results are proven by these guys over and over again. Personally top speed is not a concern of mine but I know Terry's new build should be quick, and I've seen Russ's video of him letting off well before top speed and doing 70mph. Fast enough! I just can't wait to run mine all day never worried about the dry and still only burning 10-12 gals
