Can I run a Digital 7 PN#7531 we with my MSD Mag 12? and what advantage would it give me. I am not sure they are legal for top sportsman.

Also I want to run a crank trigger on my lower blower pulley, RBS superchargers says they make they're ownoff the shelf. Does MSD make one that bolts to a lower blower pulley?


Thanks

You can run the Pro Mag 12 with a PN 7531, it will give you full control of your timing and smooth digital rev limits.

I highly doubt that it would be legal for T/S.

From my understanding the only boxes that are legal for use in NHRA/IHRA sanctioned events are the 7530T and the 75301. To connect the Digital 7 to the Mag you need to use this diagram-

Then in the Data Editor you change the following settings-

Under REVMAX you change OUTCAM to OUTREV
Under CYLCNT you change it from TACHTRIGGER to TACHTIMING
Under TEST you change it from SPARKON to SPARKOFF
