Best coils for boosted Ls?
Indeed they work! The mustang looks to be a budget build, if you have an on3 turbo, stock manifold, etc you probably aren't going to spend a bunch on ignition upgrades if the OEM stuff is working. Nothing against it, I think its awesome. Other guys like to splurge off the hit on the build so they don't have to upgrade down the road, and sometimes (and dare I saw often) they aren't any faster. Some of those lightweight chassis are quick without having to make a ton of power, tube fox can get away with 1100hp and crack 4.5's while the guy that wants a street car that runs 4.5's has to make more like 1500. Hellbents car is just insane, is it his now or he was doing the tuning for Adkins if I recall?

Spark Energy Release The small SPG of .016" can allow for a long ARC Duration even with the energy release of stock GM coils (100mj)
This can be a waste of energy due to the fact that the sparkplug will continue to arc AFTER combustion is complete.
A larger SPG of .045" - .065" will produce an ARC time better suited to ignite the fuel/air mixture when the piston is in the best position.
This will increase engine torque.
The LS-1 Tech users who fit the IGN-1A coil report an increase of 18-22 HP with a 500 HP engine.
They also have reported better throttle response and an increase in MPG.
