I installed mach.26 in my hyper and it run 2 1/2 gal. already, and have sportwerks .26 in my raptor too. both don't have problem yet. One thing my lhs told me about this engine, when the first batch LST went out of stock, they probably rush making the second batch as they have
a long list of order and probably the way they make this engine, they did also rush it and it cause them big problem. You know if you make something and specialy rushing it, it will have a poor
quality finish. Those engine I have was been order after maybe 2 month already when they started correcting this problem. I hope..................
I love this engine because it have 7 port ( 2 boost ports, 2 transfer ports, and 2 guide ports and the exhaust), it have 2.75 hp. turbo port crankshaft. The Mach is a non pull, the sportwerks is w/ a pullstart.
