Update Ignition System

[davemccorkle]

I posted a thread on twin plug or not and after much research I am not sure if it is the best thing to do or not.

Is there a plug / coil / ignition upgrade I could do that would get me almost as good as twin plugging?

2.7 RS 10.5 compression, very wild cams

Thanks

back off the timing and run better fuel.

I will do that for sure but should I upgrade from the stock coil?

It couldn't hurt, but it is certainly no substitute for twin plugging.
Edit: Steve Weiner at Rennsport Systems has a good explanation here (article #6).

Dave,

The ONLY downside to twin-ignition on a 911 is the expense,.....

There are many benefits that include improved torque, quicker throttle response, cleaner running, and improved resistance to detonation. The latter item becomes much more critical when compression ratios exceed 9.7:1 on pump gasolines.

Without knowing all the details of your engine including what octane fuel you plan on using, I couldn't offer anything more specific,...

I am starting to think twin plugging is the best thing to do. Thanks for the advice.
