I'm about to install a pair of Great Plains dual-plug heads on my 2180cc VW engine. Anybody know what make and model of 10mm plugs folks are using for the secondary plugs?
I'm tearing the engine down anyway, since I found a broken cylinder stud yesterday, among other things. I noticed the broken stud while working on a new "performance" website for N891JF (http://www.n56ml.com/n891jf/performance/), and noticed the CHT for cylinder #4 wasn't even registering. After the stud broke, the nut backed off and the CHT ring was just floating around in space. See http://www.n56ml.com/n891jf/performance/ for that shot. I'm thinking Megajolt or Megasquirt to fire these plugs. Given that I have injector bosses on the intakes, I may just have to go Megasquirt. Either of these will manage spark based on load and MAP, so advancing the ignition at high altitudes could yield some real efficiency increases. Megajolt's not very expensive either...something like $170 for the controller, and it uses inexpensive Ford EDIS components that came on millions of 90's Ford cars and trucks. Don't forget my spark plug question. Plug wire info would be good too. Thanks, -- Mark Langford ML at N56ML.com http://www.n56ml.com
