Timing for 150 nitrous (table pic)

[Redfenix]

How does it look



Im shooting 150, vp on a dedicated at 6 psi, autolite 103, AFR I guess it will be around 12 since Im still figuring out where to settle for a safe start, using microedge to control shot, this is a base start since Ill make change on what plugs says

I'm not sure what an autolite 103 plug is. But if you were running a TR7 (BR7EF) that's a safe colder plug and had a standalone with all race gas i'd only pull out 3-4 degrees on that shot. I would shoot for 11.5-11.8 afr

also while we are on timing..... got a good question. lets say shoot a 100 dry and 150 wet set up as 2 systems. My question is what would be a good timing and a good afr for 250? give or take 25hp on the systems thanks for imput. I was thinking i am at 28 deg on hp at like 13.3 afr and was figuring maybe 12.0 and like 22 degrees. The reason why 12.0 afr is because of the dry adding fuel when it hits the maf.... thanks a bunch

You'll want more timing pulled for just a 150 shot. Learn to read the plugs and you'll get the nitrous running well! Most LS1/2/6's that I've tuned for spray will have 8-9* pulled for just a 150 wet shot. Another 100 dry on top of that would probably be at least another 4-5* or so. Reading the plugs will tell you where to set your timing at!
