Tech West Racing Services MSD Upgrade

[Tom Goldman]

Pat , at this years Dutch Classic at Maple Grove ,I helped two racers with MSD 7AL3 units diagnose problems.
Both units failed on the magnetic pickup input ,but still would function when tested on the points input.
I've been told this is somewhat common on the 7AL3.
Do you have any upgrades available to improve the reliability of the magnetic pickup input ?
I'm concerned since I also have one in my car.
Thanks , Tom

Pat,

My toy will be arriving late this week or early next week. Also, I sent you a PM to ask a couple questions. Do you prefer I use techwest@techwestracing.com to contact you?

Thanks,

Jeremy

Are these the recommended coils for all 6al boxes, regardless of the combination?
I've been using the same MSD 8207 for at least 15 years.
I've never had an issue. The last bracket race of this fall in October, I didnt have to change my dial for 6 rounds and went 3 rounds in a row within .004 with only about 10 minutes of downtime between each.
I'm still interested in the upgrade, just curious, if it will be beneficial, or if it is just cheap insurance?

Thank you,
Clark Doukas

This is Cad's Dad. Is there an upgrade available for the 6AL? What are the sparkplug wires that you recommend? This is a 12 to 1, 383 SBC. What wire electrode sparkplug would you recommend.
Thanks,
Duke

How many volts input will a 6AL stand? I know your Maxpwer 20 is 20 volts. Will a 6AL stand 24 volts input?
