Finished my mod. If anyone is wondering, I used a 3mm bit in the Dremel. Now to install them and see what happens. Hoping for good results.

Where are you located?

It is, and it isnt. The very first time this was attempted was back 1918 if memory serves, but was abandonned because at the time they were only able to make it work - fairly well - on fixed rpm stationary engines. The system was redeveloped by federal Mogul back in the 2000´s, but again, for fixed rpm CNG engines to improve burn and clean up emissions as well as increasing power output. Maserati has a similar system in their MC20 engines, but use twin spark technology to perfect it. This is redeveloped (and patented ) for conventional SI engines. It works on most engines, especially Hemi headed engines respond very well. Other engines are a little more reluctant to deliver and takes some tuning. for instance a Jaguar MKII 3,4 rated at 208 hp pulls 231 hp with the PJI´s and a hotter coil. A 2,7 Porsche 911 180 hp Euro spec with a MSD6 over the stock Bosch CDI, now pulls 201 hp. All this basicly on the same fuel. Minor rejetting may be needed and the ignition timing needs to be adapted. As a rule of thumb, 2 degrees more at idle, 2-4 degrees less at max (WOT) dependant on bore and chamber efficiency. In general we can say that the higher the compression ratio the better it works. Especially with high compression engines the fuel efficiency can be dialed in to get incredible results, like + 10% on cruise. BUT, it often takes a little tuning to get to that. Normally anywhere between 3 & 8% is considered easy obtainable.
