Can anyone tell me if Beru spark plug wires are soild core? Just had a major engine rebuild and installed an MSD 6AL ignition system in my 79' 911SC 3L and it seems to "stutter" at higher RPM's.
MSD manual warns not to use solid core wires with their system. Just wondering if this could be my problem.

Beru wires are solid core. Did you use an MSD coil?

I've done quite a few MSD installs in the past 35 years and I always use suppression wire.

I used MSD 6AL and Their MSD Blaster Black coil.
What brand of Plug Wires would you recommend ?

Make certain you mount that coil straight up, not upside down.

I make up my own plug wire sets, however you can use either a Clewett plug wire set or a Magnecor one.

I used an MSD Blaster Black Coil, Thanks for the info, I will switch to suppression wires, what do you recommend?

ran that setup many yrs on my track 914-6 2.8 with no problems frequently turning up to 8000

- the important factor is that the suppression is in the connectors, so you do really have it (which meets the MSD rqmt)

suggest testing your connectors for potential source of your complaint

check this "some of the early cars had black connectors that measured 1K. the brown ones are 3k." - at http://forums.pelicanparts.com/porsc...eter-ohms.html > or just google it

eventually i switched to magnecor per advice from Steve above & currently run 'em on my motronic 3.2
