Granatelli coil pack...price??

they had a group purchase over at modular depot in the $400 range.

I have read on cars with higher boost and can help with issues of blowing out your spark. If you go search over at MD there is dyno data availible. I would personaly only cosider it on a higher reving car or boosted car. on a bolt on car i would spend the $500 on cams or something that will yeild more power.
