Re: Msd 6al
The answer is it depends. I was never a user of an ignition box. Thought it was all marketing hype. I was running low 7's in the 1/8th just fine with my Pertronix distributor.
Then I added boost. I still thought I was fine. Then I added water methanol injection. Whenever the water/meth would activate I could feel the car nose over a little. I spoke to my vendor and he said it was the ignition. I was skeptical but thought I would give it a try. I added an MSD 6AL2 Programmable box. With no other changes the car picked up a tenth. I just didn't have enough juice to light the fire.
Soooo...if you don't have enough juice to adequately light the fire then yes, an MSD box will give it more power. If you have plenty of fire as it is, the box won't help any.
If your signiture is right and you have an honest 650 HP naturally aspirated I assume you have high compression and will benefit from the MSD. Do you take it to the track?
