I would think that the hardest part of doing this would be getting the tune right.
If my understanding is right (and it is quite often wrong), then the use of N2O on boosted engines is pirmarily for the intercooling affect. So a smaller shot should work very well.
I totally agree. A 50 shot will pay dividends while a 100 might turn you into a suicide bomber. 5.0's are so simple that there's not much to tuning a combo like that. It will depend on the type of unit. A dry unit would require almost no tuning, maybe a little timing retard, if your injectors are properly sized. A wet unit is a little tougher because you may have to get creative with the fuel jetting on the unit. I've been wanting to try that for a long while. I keep chickening out. I say go for it. Be carefull though- that 50shot will give you more than 50hp going through the blower and a lot more tq.
