Has anyone felt a seat of pants difference with this or DYNO? I felt a noticeable harder pull along the entire rev range on my 90 GT with a considerably better pull in the higher RPM's with a similar Crane HI-6. I have also heard of sn95's having problems with the crane..and maybe MSD.. Any ideas?
Does MSD make a difference????

it would probably be most noticeable with blown apps where spark blowout is more common. n/a i doubt it would be noticed much

I run the Crane Hi-6 on my 95 and noticed a massive improvement. Haven't been back to the dyno since the install, so I can't say for sure what the gains are. From 4k+ it is SOTP different though.

Instead of one spark to ignite in the combustion chamber, it sparks several times in rapid succession for a better ignition. Hence, MSD = Multiple Spark Discharge. An aftermarket coil will increase the intensity of the spark. Correct me if I'm off my rocker, but that's what i've been lead to believe.
That's correct. Some folks swear by them while others notice no difference. On foxes, dyno runs have shown the stock ignition to hold up to almost 400 HP N/A. Like said, power adders almost definately require a box. Anytime something's done to change cylinder pressures, significant stiochiometry changes, etc, it's a good idearrrrrrrr.parchisi said:
For a mild NA combo, I personally feel that if the stock ignition is up to par, differences felt shouldnt be huge. One thing's for sure - it cant hurt.
Makes sense. I have hear the following many times:
"On foxes, dyno runs have shown the stock ignition to hold up to almost 400 HP N/A. "
I understand that it holds up but can it perform "better"...I am leaning toward getting one considering my personal experience and a few you guys. My 90' just ran better with it, snappier off the line, swept better throughout the RPM range and harder pull to the red line. It was completely stock but for exhaust.

I gotta side with JT on this one 
If your stock oem ignition system is in good shape
and
You be a NA kinda guy
The gain is gonna be small ... if any ... with aftermarket systems
however
Our cars are gettin kinda long in the tooth
sooooo
Our oem stuff is most likely not as crisp as it used to be

No changes. I just plugged the new one in and wowee - made a significant difference. The car had about 26k miles on it at the time. I posted over in the older mustang section to see if there 87-93's showed a difference but no replies on it.

huh.....how can it really spark multiple times when your revving up near full throttle? there would seem to be no time at all.....?
