88 MPH is what my Twin Roadrunner is doing with CMB 80 Hr's, 11 3/4 pipe length and H48 Stock props. see why i like running the 80 engines MR English i go just as fast as you do with smaller engines and smaller props get it..

I think the boat needs a new driver also LOL (too many Flips and somersaults thru the course) :lol:

this was at our test lake in south florida, the previous run(same day) with small gps mounted in transom came back at 88.9mph...

pipes are long(113/4), head clearance is at 17,000,50% nitro..very conservative set up, after this run the plugs came back like new and shinny

theres nothing like the roar of a twin!! enjoy
