GM Wastespark whats the Max Dwell time

[Alex325icturbo]

Hey. Can anyone tell me whats the MAX dwell time for GM wastespark coil pack

Not sure on the exact numbers, but aftermarket MSD coils for GM have an optimal dwell time of 2.5ms for reference.

Are you trying to crank up the dwell for max spark without melting 'em?
