Default Need new ignition..advice please

Building a new car, 900HP N/A, big tire. Should run in the 9s.

I had plans to run my 7531, but understand that NHRA has banned that box.

Are there any of the Digital 7s that ARE not banned. I will be racing Super Pro, Brackets, etc.

So, I need to buy a new ignition. What about the Power Grid? What all would I need?

I have a 8261 coil.

If you think I'd be better off with something else, please advise.

Thanks.

7531 is legal in nitroud pro mod and your outlaw classes ,
now, if your running brackets or super pro....you would not use that unit at all.

the question is: what do you plan on doing ? what do you want to control?

I will be running Super Pro mainly. Would like to be able to control everything the 7531 does except the slew rates, traction control. Launch retard, top end retard, and the ability to graph it with the software.

Thanks

No, in fact the distributor I have, MSD Pro-billit, has a cap-adapt on it with a grey crab cap. Not sure the grey cap is MSD.

Well and good, thanks for the links to the parts you sell. Question though; I have a Moroso drive mandril on the balancer, how would I mount the crank trigger wheel?

depends on the drive mandrel , some will require some machine work to get it to center on the wheel. Here is a drawing of the big block crank trigger wheel.
