Nitrous plumbing A1A...??..

What you guys are doing is ok, its progress, I would call it overkill personally......as I said before I didn't retard much so didn't need retard boxes although I could've added one to the MSD system I ran as many could today. From then on a single 4 system is just 1 extra fuel pump (not 100% necessary), 1 extra line/ regulator/guage for fuel, 1 micro switch for WOT, 1 main arming switch and thats it. If you run your N20 a bit rich on the fuel you don't even need the retard box unless your on the edge with CR and run an early intake closing cam on pump swill.

A bit like running 9's back in the day with an all iron 440 with 906's and a .750" roller cam...today its 500+ci, superior ally heads and the difference isn't worlds apart in most cases.....just how I see it being an old'un.:)
