this guy had no clue what he was doing, cranked a ring land on the first pull because he threw too much fuel in it to make it "safe". He didn't communicate any of this until I saw the AFR go to 9.9:1 during the pull and I quickly realized he was clueless. before you know it, theres parts of my piston rattling in my muffler. I later found out he never did a nitrous tune before.

He filled the cylinder with fuel, which is not all that compressible, and boom. nitrous 101

please the slight addition of fuel is not "filling the cylinder up".: A .055 jet is for fuel injection at 45 PSI can support 150 HP of N2O. That would be fuel for all 8 cylinders....

Of course you can figure the mole count of air and fuel and than calculate the volume of fuel that way.

Or you could look at the brake specific HP of the cylinder and calculate fuel that way

Or you could get the DI duration and flow rate in CC and have a direct comparison to 6.2 liters / 8 =

Modern ring lands are high up for smog and MPG, they are significantly weaker that a 1997 and below era ring land.
