WOW this is so helpful I'll have to watch this about 3-4 more times in order to really soak it in but thank you so much the way that you explain the stuff makes it so much easier
Let me stress that this is my opinion since the first thing I usually get is an argument but I typically will run 12.0:1 up to about 750hp. I’ll then taper down to 11.4-11.5 up to 1000 and usually level off there. Past that I don’t have enough experience to comment. Nitrous can get too rich earlier than boosted applications typically. The amount of nitrous isn’t really related to pump gas as much as cylinder pressure but for general terms on LS engines I usually stop somewhere around 150-200 before going to pump gas but that depends on engine size and chamber shape, plug heat range and tip style etc. Gotta keep an eye on plugs and make good decisions
@@greenshortsperformance472 thanks that helps big time. I don’t understand why people always want to go to 11.8 or richer afr for nitrous some times.. What about timing you add some back in after peak torque like what people do with boost?
@@408lethal yeah I typically run a half AFR leaner than boost but it’s a little different since nitrous increases flame speed. For the same reason I do not add back timing. You pull timing across the tq peak to protect from detonation however you pull timing with nitrous to make best power. If you didn’t pull that timing you’d actually probably not knock just make less power. So I recommend whatever timing you had for best power NA, just pull 2 degrees per 50 and add back based on what the plug looks like.

need this service in Atlanta
Nice to the point video
What afr do you like to follow per nitrous shot?
And how much nitrous is okay with just pump 93?
