MY experience with the Pertronix Hall effect system has been very good.

I am sure there are failures.

I have heard the magnet argument and have run a scope on my car and could not find this alleged problem.

I am sure a Crane optical system will work well too.


I have owned my 1973 2.7 EFI 911 for 20 years. Ran the first 5 with points and it drove me crazy. I could feel the difference as the rubbing block wears away and and the dwell changes. I was adjusting points every 5-6000 miles.

Once I was stranded onside the 101 in heavy traffic because the gap closed.

I got tired of it and put in Pertonix. 15 years and 85,000 miles later the same Pertronix unit is performing perfectly.



"When they fail in the middle of BFE, you're vulture food. With points, you clean, re-gap, and yer on yer way again."
I carry a spare set of points. I carry a brand new extra Pertronix in my tool bag, Have not needed them in 15 YEARS!

"Just use points Pertonix is prone to all sorts of problems don't waste your money."


BEST $100 I have spent on my 911. HIGHLY RECOMMENDED
