The end result was great throttle response and better power band throughout. Acceleration decreased again, this time a little more to 5.51 seconds and top speed increased to 56.8 mph. As another benefit, the Vortexes look pretty cool too. The next item we tested was intake grates. It gave the best compromise between rough water hook up and smooth water drag.
Installation is easy.
For those of you who are interested in more acceleration, listen up. Acceleration dropped to 5.44 seconds 0-250 ft. Although I can say with confidence that I believe we could have alleviated the top end problem by re-jetting the carbs. But that doesn't fit in to our testing criteria yet. You can get this waterbox from TDR or from Tucker Rocky.
