Scramble NOS with Belt Driven Supercharger timing question
 

I’m using a TorqStorm Supercharger and have a MSD Boost Timing Master to pull timing boost referenced. I can adjust from 0 to 3 degrees of timing to take out per 1 psi of Boost. Self explanatory on its function.

My question is when I add a 50-125 shot of NOS to it for a Scramble, what kind of additional timing do I need to pull?

I will be controlling ignition with a MSD 7AL-3 and it has a multi-step retard function for nitrous. Do I need to override the BTM if the second is used? That is the problem I’m struggling with.

Please give me your input. Thank you

I have no idea how much extra timing to pull but it sure sounds like a fun set-up :cool2:

I have a 8-71 blower and a fogger between the blower and the carbs
I use the same MSD as you do and have a multi-step retard for the
nitras, I take out 8* of timming with the multi-step added to the
timing that is takeing out by the btm-msd. I'm spraying a 150 shot
hope this helps. Without the xtra timing not takeing out by the btm-msd
it wasn't noticible untill I got into boost.
