nitrous jet stampings=hp conversion chart?
Looking for a jet=hp conversion chart for a dry setup, I got this from gLok
a while back, wondering if anyone had a scale that went up higher, you can look at this chart and guesstimate what comes next but I don't know for sure, getting ready to tune it for a big shot and want to be positive, thanks in advance.
HP Gain / NOS Jet Size
25 / .024
30 / .026
35 / .028
40 / .030
50 / .032
60 / .034
70 / .036
85 / .045

Called Holley first, not sure if I got Joe Blow in their tech dept. or what but they told me every nitrous system is different and every vehicle is different which is true to a certain extent. Explained to them what I was doing- vehicle, setup, etc.. They told me there isn't really a chart and the only way to find out is on a dyno by stepping up jet by jet. Sorry, I don't want to buy a buncha jets I don't need.

Yes, going to try between 100-120 depending on what I can get away w/ on pump gas. Just sprayin through the charger. Hondata controls will add fuel and pull timing for me.
Looking at the chart the last # has .009 increase on jet stamp and 15 hp gain. Using that rule of thumb you'd think 100/.054, 115/.063, and so on.
Any ideas? I'm driving 4 hrs to have this done on a dyno and want to be properly prepared.
Thanks
