I want to buy an aftermarket for my 92' Corvette engine because of more performance and time retard for a nitrous system in future: What is the best system MSD or Crane ? Any experiences ?
Thanks for any help !
I've used the MSD 6BTM on a bunch of turbo/supercharged engines where I needed a boost retard. This system works great and is easy to install. You can adjust the boost retard between 1-3 degrees/psi boost up to a maximum of 15 degrees retard.
The system throws lightning bolts at all speeds and multiple sparks up to about 2500 RPM.
I've had good luck with this one, but for a nitrous application, you're gonna need something more exotic like a 7AL-3 with a multi-step retard capability. This will allow you to retard the timing for the nitrous system.
