Are you sure you need one? In general they aren't needed. I don't use one, i just gap my plugs down.
i thought more fuel typically means it's easier to blow out spark because the resistance in the cylinder is higher making it harder to jump the strap, less fuel is easier to ignite but maybe I'm wrong. I use BRK7E which is the vpower version. I could probably get away with 6s though. I doubt it's the plugs. I don't have any experience with that cdi but i have a hard time believing it can do multiple spark all the way to redline.Plugs are NGK BKR7ES-11. Wires are DUI Livewires.
Multi Spark Ignition Box. Small form factor produces 30% more energy. Better spark timing and true Multi Spark function.pertronixbrands.com
My point was less fuel shouldn't cause more ignition blow out/break up. I think you have something else going on. I'll have to think about it but i would probably do a voltage drop test to see if there are any ground issues.I might agree but we aren't talking a large fueling difference. I went from 10.80 to 11.5.
True. MSD has outsourced their products which has resulted in poor life expectancy and in general poor quality. I do have a 6al2 in my car from about 10 years ago for the 2 step feature but its not plugged in and I just use the stock ignition plug until i take it to the track. It was also dyno'd without the CDI plugged in. I have the OEM and MSD coil plugs at the coil so I just unplug one and plug the other in. 99% of the time my car uses the stock ignition with no CDI. I also replied to your PMThat's just the thing. The older boxes seem to be fine. The problems seem to be with the new Chinese made boxes.
