There is a BIG misconception that there is NO power to be had in a more powerful ignition system. EVERY and ALL of our testing has proven that theory WRONG. Along with a cleaner power band there are also the driveblilty benifits. With a plug gap at .018 and even heard of some people running .015, the cars low speed driveability suffers drastically. There is also proof of less knock with a properly engineered system. A car doesn't have to exhibit misfire to benefit from more ignition energy.
Stay tuned as we will be heading back to the dyno and will post ignition logs, comparing stock coils vs non-cdi vs Pro-cdi systems.
Ignition is the MOST overlooked aspect of the average build.

The OP was talking about torque increase and budget was mentioned and while I do not disagree that a greater spark voltage can and does make horsepower for me it is not worth 8 hp for the cost of the upgrade. If gapping my plugs down did not cure spark blowout that was happening then certainly I would upgrade the ignition.
There are plenty of 400-500 HP Evo's on stock ignition as far as I can read.
I apologize if I caused or created a misconception
PS every car I have ever owned that gets modified has had an ignition upgrade of sorts except this one (yet) unless you count colder plugs. An Accel or MSD coil with plugs and wires on a V8 has netted 4-8 HP (4 on one car and around 7-8 on the other) not unlike your COP for the Evo.
Now back to the original post
