The adventure continues! Finnegan is still smiling, even though he and his buddies are thrashing on this thing. But man what a beast this beauty is. If you missed the first part of this three part adventure, click the link below. We’re not going to tell you everything that happens, because the video is great and you want to watch.
Episode 220 of Mike Finnegan’s Garage is Part 2 of a 3 Part Series about my first weekend back behind the wheel of a real drag boat and it did not go well. We had parts fall off the boat, corroded parts that didn’t work, and we ended the day with a motor milkshake and broken valve springs. But, we did make a couple of really good passes down the liquid dragstrip at over 131 mph in our naturally aspirated 2016 Ralls Precision Machine Cheyenne jet boat and so I’m still very happy. What makes this boat unique is that Andy Ralls cnc-machined all of the aluminum hardware on this boat to be as light as possible. He also had E-Ticket Boats in Lake Havasu, Arizona, laminate the hull entirely from carbon fiber. KMG Boats painted the red, black and gray hues, while Marine Performance Design blueprinted the Dominator jet drive. The boat is powered by a naturally-aspirated 632ci, 10.5 liter aluminum Big Block Chevy engine that produces 1,300hp without nitrous, or turbos or a supercharger. The engine was originally built by Jim Guthrie and recently freshened up by Mike Miller Racing Engines. The engine features CP Pistons, Carrillo connecting rods, Total Seal piston rings, Dart Big Chief cylinder heads, a Dart tall deck aluminum block, an HRE tunnel ram with billet runners, and Gen 3 Holley Dominator carburetors. The electronics consist of an MSD Digital 7 ignition box and a Jesel front drive distributor. The boat was wired by Zack Rauscher. This boat has ran 132mph with an ET of 5.8 seconds on a 1,000ft drag boat track. Stay tuned because tomorrow I’ll drop Part 3 of this adventure, which will show you we tried to solve the water in the motor oil problem, replace the broken valve springs, and get the boat running again for race day at the National Jet Boat Association Final event of 2022!
