Without it the blower will blow out the spark. I had this happen on the Cobra with only 10psi of boost. I added the 6AL and no more blow out. If you want to try it without one we can we'll just need to close up the spark plug gap but I recommend that we install one to start with.

Blow out the spark? What gap were you running on your plugs?

What kinda money to you want to spend?


I know you don't want to hear this, but back in the 80's we ran STOCK (recruved) dizzies with a good coil with roots blowers. We ran a .035 to .045 plug gap with out any problems.

If we are going to spending money for real trick stuff is fine, but lets be sure we need to. So why don't we find the Dizzy we want to run and go from there. Just my 3 cents.:judge:

.035.

Ok, then what MIGHT have helped you was the CD part of the 6A box increasing your dwell on the spark and voltage to jump the gap with the cylinder pressures you are running. Just another thought.:D


Multi spark is only good for low rpms. It only really helps because it can fire a cylinder with poor fuel air mixture. But only at the lower rpms.

MSD makes a "Streetfire" HEI that is $150.00 brand new, all day long.
I can install any curve you want, or pin it at 36*, or just use light springs.

That makes ZERO sense to me.Zip,nada,zero, no comphrende.:huh:

You just love those "HEIs" don't you?:p


I don't like the coil in cap idea. But the spacing of the contacts in the cap is good. The wider the distance the better.:thumbs_up:


I just found an HEI dizzy in CIs catalog for $94.95.:rolling:

Frankly, I still love my point dizzys. But as for HEI, the magnetic pickup is FAR superior to any optical pickup. Remember Optispark?:suicide:

I guess these guys may not know I have a Sun Dizzy machine.;)

Opti-no-spark????:laugh:

I remembered you have the Sun Machine. :drink:


I will be bringing you my Dizzy in the NEAR future. :drive:
