msd ignition

whats the go with msd and crane ignitions? Do they make more power and torque? I run lpg , will this ignition make me more power? Which one should I consider getting for street peerformance?

Re: msd ignition

For street performance, I'd say keep your stock ignition box and upgrade something else, like headers, intake, or something. You wouldn't see enough of a gain using an aftermarket ignition controller unless you're running some form of forced induction, nitrous, or really high compression.

That's my opinion.

I tend to agree with this. Unless you have hard start issues/ignition problems don't bother.

I bought an MSD 6al purely for the limiter.

Re: msd ignition

They are capacitive discharge (CD) ignitons. They give off more sparks (spark scattering) to optimise fuel burning. You need a compatible tacho or a tach adapter because of the CD doesnt trigger a normal tacho. The rev limiter is a really good idea except you have to have change a chip if you want to adjust the limit.

You can change the resistors in the chips yourself and save lots of money.

I think the key issue has been missed.....

LPG will benefit from any ignition improvement, as it is more "fussy" then petrol when it comes to spark. IMO an MSD-6 (or variant) will do wonders for your engine.

I've already gone a bought a bunch of "pills" for my MSD, mainly because they're the same as the pills in the Autometer shift light i've borrowed (just small and white versus yellow and huge, same pins though), but out of interest, got a table of values or similar for the resistances?

Re: msd ignition

The mallory hy-fire VI-al ignition box is just as good if not better than the others and you don't need pills to adjust the limiter. Looking at the specs of system i'm glad i went this way. JMO.

Yeah they seem to be a bit cheaper with the control box as well - $325ish vs $450ish for msd equivelant

Twice as much for there dizzies though

Re: msd ignition

True there new series of dizzys are pricey. There race sreies dizzys are impressive. Guess i'm lucky that i have a comp 9000 only had to replace the unilite module recently. Not bad an old dizzy.
