Here's a chart I made in networking class. (Yeah I got bored), its what I was told to run for jetting for the NOS 5115 dry kit, to run higher than 80hp you need a shim in the N20 regulator. Other than that get the jets and go from there. I created in MS Excel, just unzip and open.

thanks for the chart, one thing that doesnt make sense is the higher shot you want, after 100hp shot the fuel jets get smaller than the nitrous, just wondering if that is safe?

Yes, the more hp you want to get,the smaller the fuel jet because smaller jet increase fuel pressure in the fuel regulator ( remember ? there is no fuel flow through the nos tee fitting line because it's dry system )but in the same time n2o jet is getting bigger because more juice would be required to run higher hp.

i just thought it was strange cause with the lower hp jets the fuel is bigger than the nitrous, but i got it now
