Below is the chart for the Air/Fuel when I Dynoed the car. The blue dot is running 100 shot of dry NOS putting my AF at 13.07.
The Red one is on motor only.
My question is, do you think is safe to Run 150 Shot specially with a few gallons of 103 octane Gas ?
Also the car was tune with LS1 Edit to pull some degrees off when Nitrous is activated automatically.
I want to take the car to the track to see what it does but I`m affraid to have a full pressured bottle and 150 shot.
Please let me know.

 

Imo, it needs to be fattened up a bit, or...

 

more feedback would be appreciated.

 

Most guys like around 11.5:1 ratio on the bottle. N2o causes cyl pressure to increase and additional fuel helps to cool this down and avoid detonation. You can get away with less than optimum a/f on a small hit, but 150hp should be a little richer, imo, for engine longevity and safety.

 

13.6 seems like a lot n/a... I like the af in the low 12's w/ a 150 shot.

 

Fatten is up...as Robert stated it can aide engine longevity.
