S1 cossie managment dizzy&faze sensor
coilpack mate ive got it on mine although mines not running yet!
ive just converted it efi engine on cossie management with wasted spark, jano has been a great source of knowledge every time ive rang he has always answered all of my questions.

The Std coil produces 36,000volts a groupA coil produces 40,000volts and a coilpack 46,000VOLTS, i have the GrpA coil which has been perfect, didnt really think it was worth the extra spend to convert to coilpack

The parts are available for many different engine setups from a std CVH, Zetec, ZVH, Duratec and even a Cosworth Yb. On a Yb the phase sensor setup that jano offers works with small turbo Esc Cos engines and also cosworth engines that can not or dont want the cam sensor on the rocker cover.. New ways to control the spark without making loads of holes in covers and needing extra triggers drilled and tapped in to the Cam shaft.
Then you go on to say is a coil pack better, better than what? LOL.
If you have cosworth management on your engine then using a coilpack (which is better) can be done very easy using a coilpack driver available from Stu at MSD.
Hope that helps mate.

Of the 40,000 volts your Group A coil pack may produce under ideal conditions, you will get no more than about 6000 at high revs because the available charge time between cylinders is tiny. I'm sure you can appreciate how many times the coil charges and discharges at 6000rpm? Now add into the equation you lose around 20-30% of your spark voltage when you have to jump the daft gap in your dist cap and on the rotating carbon brush/rotor contact point, you can see your spark voltage is pretty poor.
A wasted spark coil pack is TWO 46000 (Taking your word for it for ease) volt coils that take it in turns so they have twice as long to charge, usually giving in excess of 20000 volts at very high rpm, and they don't have to jump a spark in your dist cap or lose power in the carbon brush...
You have totally missed the point of going to wasted spark I'm afraid mate.
