Default Mabey I知 learning,,

Ok, I致e been reading some more, if you lock your timing on a blower enigne, will it help with rotor phasing?the previous owner melted the top post of the coil,3 holes burned all the way through. Could this be caused by improper rotor phasing? I知 totally new to super charging, and will probley only get one shot at this befor my project boat turns into a parts boat.I have two msd- 7ml-2 ingitions, one has a couple burned resistors. ( the one that melted the coil)

rotor phasing is not changed with timing changes, locked or not,

Phasing is the relationship of the rotor under the cap posts. ust type in rotor phasing into your search engine and read away.

Why do you have 7 series ignitions ? Although not limited too, most are only used for short duration racing events like drag racing and top speed runs. A typical blower motor used in a boat does not need a welder as an ignition system.

What do you have for a motor set up ?

That痴 the ingition that was in the boat when I got it as a project boat. I was thinking after looking at that 7-al2, it was not right for the boat(39団hris craft scoripion). So, I need to buy two 6m-2l ? the previous owner had this boat set up very bad,from everything I知 seeing.plug wires all zip tied in one bunch,3/8 fuel supply,small water/ fuel separators,etc,etc. I知 sure hoping to get it set up right,have new fuel systems,160 gph,all 1/2, trying to get the ingition痴 figured out now.

We also installed innovate afr gauges,Im going to have to extend the port sensor wire , bought the 18 wire, to short, but with the 5 wire that came with the gauges I知 hoping it will be long enough.

Swap to Daytona ignitions. Locked timing isn’t a great thing. Yes it’s been done for years and engines have melted done for as long. A better tunable ignition is far superior to locked timing. I just installed the Daytona’s on my NA motors. Engines were dropping 450+ rpm going into gear. Now with idle stabilization it’s only a 200 rpm drop or so.

Just looked at the Daytona ingition, at 600 each why not go with safeguard? Would it be better to have knock control? I知 totally new to these sc motors, I really miss my n/a 502痴 in my 40 Excalibur! Ran perfect with hei痴 , still had vacume advance! Would turn 6000 rpm very easy, 21 pitch 3 blade marage痴. What if I got a pair of 65000volt hei痴 , removed the vacume advance, set them to fully advance by say 2800? Like I said ,I知 open for suggestions, never done sc befor.
