when would u switch from a nitrous carb plate to a direct port
I was wondering at what shot of nitrous would you change from a nitrous carb plate to a direct port. When would it not be safe to run the plate. I'm running a single plane manifold and want to run 250-300 shot with racing gas. I'm not the richest person and a fogger system is a little hefty, I was looking at a big shot kit instead, but if it's not worth the risk. All information is helpful, thanks.
