I phoned 2 dealers that I know build these engines and they both recommend no nitrous at all. These are just naturally aspirated engines that build over 700hp and gobs of tq. and can be driven across country,so they said.
As tempting as it is I'm still not sure if I should buy one. There are so many to choose from 540,555,565 and maybe the 582 in short decks that I can add a good shot of nitrous when I need to.
