To nitrous or not?
I have an aeromotive SS fuel pump and regulator with 15gal fuel cell. Would I need dual pumps? I'm also running an MSD RTR dizzy. Would I have to go with say a 6AL box to run rev limiters?
The single fuel pump is fine (looks similar to my Holley black pump), you don't need a dedicated system at that power level. I am not familiar with the MSD RTR distributor, but yes, the 6AL has a rev limiter chip function (and it is the one I use). Not sure how you have your ignition setup, but you can add just a rev limiter to the system more than likely (MSD sells them).
My personal setup when I ran nitrous was Billet MSD distributor, MSD 6AL box, MSD Blaster II coil, and a Holley Black pump. The time when I broke a u-joint coming off the line was a bit of an eye opener...I knew nitrous made a LOT more torque, but having it snap that u-joint like that was freaky to say the least. I reacted instantly, but still herd the motor bounce off the limiter multiple times (BAP,BAP,BAP!!).....can I also say, thank goodness for my bolt in sprag, it played a big role in saving the trans.
Definitely make sure you have all the "weak links" addressed before you use it...if you don't, the little blue bottle will bring those weaknesses to light...in a very expensive way, lol.
