octane
It's surprising to me that all the "experts" here (I'm not talking to you professionals) don't know, that high octane fuel is less volatile than lower octane fuels. HIGH octane fuel has a more controlled conflagration rate (it burns slower) than lower octane fuels. Low octane fuel is more volatile and and less controllable than high octane fuel. The reason you get detonation problems from low octane fuel, is from an uncontrolled burn AKA pre ignition!! (the fuel starts to burn under compression or a spark /hot spot in the cylinder ) HIGH octane fuel "burns slower and is less volatile", so you can more precisely determine the "EXPLOSION" point of the fuel in the combustion chamber.

You would also be correct ;) Jamie / Lakeside |
Enough of the Chit chat.. Time for some noise... :yes: :eek!: :bonk: ...
Here is a clip of the Dana exhaust we installed on a clients boat. Undertaker's new Dana 496 Exhaust running on the hose(click here) :) Jamie / Lakeside Restorations . |
Dana's are finally on the boat. I hope to test them on the water this week sometime and I will post real world results after the testing. I must tell you, I also removed the Silent Thunder from the boat, so there are two variables that are changed at one time. There was some weight savings by getting rid of the Silent Thunder...I would guess about 100lbs with all the water that was trapped in it.

Good Luck keep us posted on your results.....
Undertaker:D |
sweet....keep us posted. What are your before GPS and speedo #'s?
