I'm planning on getting the Pro Street model.
I've heard good things about Jacob's, what about you guys? Experiences?

Pro-Street owner right here. Two years and going strong. I gained 0.2 seconds when my car was nearly stock (check my website for details). I can't imagine what the improvement is today because my car won't run above 4,000 rpm's on the stock ignition. I've tried it and it cuts out big time!!

Before Pro-Street, it was the Omni-Magnum.

MSD Digital 6 Plus owner right here. I ditched the MSD6BTM not long ago in favor of this one. The result, well that's relative, I'm sitll troubleshooting what I believe to be a "Conflict of Interest" using a Accel supercoil and an All MSD ignition. The conflict of ignition I shall deem it is that my caps/rotors are fouling up rather quickly, in a matter of 2-3 days, but once I get the stock coil back in there I'll dtermine if that is the problem. I'm sure it is but I'm just waiting for the MSD p/n 8876 harness from Summit. But I will tell you this when I have a clean cap/rotor, it'll pull nice and hard like Willie said, above 4K RPM the stock ignition craps out. I can feel it pull to 6500 RPM w/ the MSD Digital 6 Plus.

Willie,
I was hoping you'd jump on this one, I knew you ran this system. How easy was the install? Did you use thier no-splice harness?
I hope to get some good gains with my modded motor. My ignition is all stock and showing it's age so I'm very optimistic.
I see you finally got the ATI blower in there! How do you like it compared to the old Paxton?
thanx

It doesn't get any easier than Jacobs designs their ignitions. You don't need a harness. Let's see, one wire to the positive battery terminal, another one to the negative battery terminal and the two stock coil pigtails into the Jacobs harness. That's it.

No comparison. My engine compartment now looks awesome with the blower, the Superfueler which adds three injectors mounted on top of the plenum and my custom rectangular airbox straddling the plenum.
