Spark Tech sponsored 4g63 Dragster goes 7.39@176

^We have both wasted spark and sequential systems available for Evo 1-9.
There are a few advantages to going sequential and one of the most important would be.
1. being able to retard the critical/leanest cylinder by a couple degrees thus adding a little safety margin to that cylinder.
Here is a simple example..lets say you are constantly blowing head gaskets around cyl#1. With the sequential system you can retard only that cyl which could potentially reduce/eliminate that problem (of course afr's need to be in check)
This is not possible with a wasted spark system as it fires 2cylinders at a time...Sequential only fires 1 cyl at a time...hence the name Sequential (in sequence)
Our sequential systems are also 2 times more powerful as our Pro-12 wasted spark systems

Also there is 2 kinds of sequential in your site? Whats the diff?

We do have 2 options for sequential systems. The dragster in this thread runs the M&W Pro Drag-4 cdi 250millijoules. This unit can only be used for DRAG ONLY as it will overheat in street applications. Click HERE for a link to this unit
If you have a street car and are looking for the ultimate Ignition suitable for street duties...look no further that the Pro-14 115millijoules sequential system. Click HERE for a link to this unit.

Thanks for the kind words and posting the updates Craig. It was a great day at the track and we owe a lot of that to SparkTech.
I'll go back to last week when Craig and I began talking about the ignition setup. Craig knew his coils would get the car where it needed to be so we started discussing what we needed to work in the dragster. I was a little slow getting him some information so we weren't able to get the kit together until Thursday of this week for the car. Craig overnighted the system to us so that we could have it for an event this weekend. Unfortunately, the event was rained out on Friday and Saturday but we were able to go make test passes today.
I got the system and was amazed with the quality in the wiring in this thing. I already had an M&W box in the car so Craig included everything I needed to directly connect to my existing box. I had to simply swap out my 4 trigger wires and we fired the car up. Top notch work!
As Craig said above, we were having some ignition breakup issues at higher boost in the car. With the SparkTech coils we were able to run 51 PSI for the first time with no ignition breakup at all and ran a new best ET and MPH, right off the trailer! Second pass we didn't bother swapping plugs (we previously were swapping just about every run) and it ran clean as can be again.
I can't forget the other people that help us out though, without them we wouldn't be where we are right now. Kiggly Racing, Extreme PSI, AEM, Fuel Injector Clinic and Hamm's Machine Shop.
On with the part you've all been waiting for: http://www.youtube.com/watch?v=RMqJpopykxs
