A lot of folks are not using .25 ohm ballasts as an above post demonstrates, that makes all the difference, coupled with the coils that make it possible to deliver what it's capable of. When they do, things heat up at low rpm. This isn't a debate over Chrome box on the street thread, I know what I wanna do & why, just lookin' for somebody else that's tried it. I value everybody's input here, but don't want too many side skirmishes straying from the focus on a switch-on-the-fly dual system. I recall a spring-loaded shift knob/handle with micro-switches that cut the ign every time You grabbed a gear, no lift shift deal, guessin' backfire flame show would've been good odds on that deal. Don't know how that ended.
