has any one done any r&d with MSD coils and digital spark boxes??

There have been a few here already that have made some very impressive horsepower numbers and as far as I know neither Hennessy nor Wait4me has reported any ignition changes that I'm aware of.

Welcome to the forum. :welcome:

HPE and W4M performance any thoughts?
:banghead:

I do add to the spark system, only i do it via computer. Those coils run a longer hotter spark. I can do that electronically just like they can, except i command it, and MSD just does a trick to the computer into making more by reporting less..

To add, On a stock setup it isnt that big of a deal, Especially if you havent upped the spark plug gap. But as you start making alot more boost and dumping in more and more fuel, a hotter bigger spark does make a difference. Look at the 03 cobra world and them blowing out spark at higher rpms. They just dont understand that you need to up the spark amplitude instead of moving it to a 20 or less gap to keep it from blowing out...

Our coils are just fine and do more than enough job making our hp levels. The others are a waste. They also dont last very long, and seems anytime i see them here on cars, there is a spark problem and they end up putting stock ones back on.
