    Default Methanol question

    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.

    I run a water methanol mix injection setup on my boat and it works great.no intercooler or the added plumbing or galllons of water weight.. ive been impressed with it.i run pumpgas 93 and a 60%methanol and 40%-20*f washerfluid at 19lbs..current total injector size is 14gph at the hat and another 12gph preturbo when ambient is high.i run a s480 turbo on a carbd blowthru ls 5.3 and making at least 900hp at this boost level.watermeth mix consumption so far is around 5qts mix to 140ish gallons of 93pumpgas.i spend about 25% of that 140gallons making passes and tuning at high boost levels.so with the proper setup u can really save money and weight in a boosted boat wether its roots centri or turbo injection works. we jus gta nice kit for my uncle from devils own.went with a 2 nozzle setup at 17gph total at 200psi.he is runnin a big turbo against a 10 to 1 alum 5.3 llil sucka gets it!

    Dare to be different, if it turns out great you can claim you planned it that way.
