Well it has been a couple days since i removed the toasted msd 6al from my mustang. So i figured id let you guys know how things stack up between the two.
start up
msd - easy starts < 30* locked out
duraspark - drags slightly < timing 30* locked out
idle-6,000
msd - no miss,clean crisp power
duraspark -no miss clean crisp power
6,000-6,500
msd- no miss still crisp
duraspark - power falls off , seems way rich.
pulled the plugs today, the plugs were a dark tan with the msd after a hard pull from idle-6,500 With the duraspark they are a hair darker
i may play with the plug gap some and see what happens peak power is at 6,500 so i cant loose the 500 rpm. Both ignitions are running a stock TFI coil.
Anyone think a differant coil may help? i noticed with the 6al differances between coils were slim to none.
:d
I don't know man, my car was breaking up past 4,000rpm and I couldn't figure it out...I replaced the TFI coil with a new replacement coil and it was marginally better, still had the problem...on went a Blaster TFI coil and a SuperConductor wireset and it's just as nice as can be(I had a $50 set of Bosch wires I put on two weeks before the MSD wires).
I would try a good coil/wire combo to see if that helps...Hell, I still need to get my 6al box in.
