5 amps at idle and 10.2 volts min
Hans-Olof Blom Hans if you go to the MSD site and check out Q&A you need 5 amps and 10.2 volt min. This doesn't include the coil. Do you know how big the compasitors need to be to put out on an HVC that makes 80-100,000 volts with 1 amp. About the size of a paint can. I have been running an MSD system for 10+ years on the cobra and another 15 years on my Trans-am. Number have posted above are very close to the real world numbers. Rick L. Ps I think you are saying that with the addition of 1,000 rpms the amps need to run the system increase 1 amp. It's more like 2-3 per 1,000 Also a 60 amp Atl can't power a ERA cobra with all the power on at idle with an MSD system. Alt putout is about 35-38 amps at idle. Msd, lights, blower motor, and 3 cooling fans, are over the max. I know from racing the car. Rick L.
