Used it in China this past weekend on a 12.5:1 race engine and the knock sensors didn't even touch the spark timing table.
But we were running 32oz of the stuff per 5 gallons of gas.
Won the race and the engine is healthy. But it didnt see the constant load it would of in a boat.
Still might be worth a look. No doubt we picked up more than just a couple points of "octane" or the knock sensors would have pulled timing.
It does make the plugs turn a funny color, but not from detonation.

It is definitely easier to add race fuel to your big blown power than it is to initially set up your injection system..With meth injection you must carefully monitor all of your temperatures especially your EGTs.
You can however achieve the same performance results running less timing and with $4.00 a gallon regular fuel.On our test boat running 15lbs of boost we would burn 15 to 20 gallons of meth per 175 or so of fuel.Still cheaper than straight race fuel as meth comes in as needed for us around 8 +lbs or so.

I talked to the guys at Snow and they said a 700hp motor could make 7 1/4 mile passes on a 3qt reservoir. I figured I'd need a 15 gallon tank to get the range I needed. The racing gas idea is sounding better.

We are still in business but unfortunately we are having problems with our web site not our product.I don't know of any companies that make a kit for a marine application other than us.Our solenoid alone costs "us "more than an entire Snow kit.
