We are currently in the midst of swapping out a tunnel ram 396 for a blown 468 in my moms fiancée's 71 Sanger flat. My brother, an import tuner type, has been touting the benefits of methanol injection in conjunction with fuel as a means to decrease fuel temps and get mild HP gains in the process. He runs a methanol injection system on his 485 WHP turbo Honda with no issues and on a friends car they saw a decrease in radiant heat at the blower of nearly a hundred degrees and a gain of 20 HP by installing a methanol injection system before the blower on that car. What's your take on something like this on a boat? The intended set-up for the engine being built is to be a simple pump-gas motor that will hit triple digits.
