Ok you're going to need to retard your timing while you are spraying, especially with that high of compression. You can run a dry system up to a 75 shot, assuming your fuel system can supply enough fuel, and your ignition timing is correctly tuned. If you want to go above a 75 shot, direct port wet is the way to go. Each intake runner has its own fogger nozzle spraying fuel and nitrous into the combustion chamber. However over there I assume you can get higher octane pump gas than us, so you won't have to retard as much ignition timing. Most of the time on nitrous requires retarded from stock ignition timing, or the use of high octane race gas, especially with high compression like you have. You could always fab up a fuel cell to use to supply a direct port kit its fuel, and use alcohol instead of gas. As long as it's tuned correctly, and you don't detonate, it'll be all good! Good luck......The darkside is waiting
