Re: dyno numbers

As a dyno operator, I think anyone that buys a performance motor should take it to a local tuner to have it dyno'd / tuned for local conditions. A good tuner has no interest in jacking the numbers,...

Re: PREOILLERS: MASTERLUBE vs.ACCUSUMP

Fountaineer, I've been thinking about using pumps for my boat. Which pump do you use? Do you have it set up for oil changes as well?

Re: PREOILLERS: MASTERLUBE vs.ACCUSUMP

zahndok, mine is installed in my circle track car. I wanted to have as much oil as possible in the preoiler so if/when the pump pickup sucks air, the preoiler would supply oil to the engine. I try...

Re: PREOILLERS: MASTERLUBE vs.ACCUSUMP

Re: Help with piston meltdown at 9 hours 454 sc

Re: dyno'd my 540 today

I just got this boat and it seems real sluggish after about 4500 rpm (half throttle). Anything over half throttle doesn't seem to add much speed, it ran about 70mph at 4800...
