You can run 100shot to be on the edge with n20. Then most likley your problem will be a burnt valve. You can push 9-12psi on a stock bottom end and you will most likley blow a piston ring. Why couldn't you run a 50 shot of n20 @ 5 psi and be safe accross the board?

Who said you could not?
You can, but it seems pointless when one or the other would accomplish the same a lot simpler. The only time to run both is when you are pushing the edge on one and just trying to get that bit more. I have nitrous I have never used because as long as I can get more out of the turbo I see no point. I think once I reach the maximum usefullness of the 525 injectors I will explore the route of having the nitrous push it over the edge.

Get a 5lb wastegare spring and an electronic boost controller. You can hit 10lbs only when you want to race and 5 the rest of the time without having to worry about filling a bottle.
The biggest problem with running both is the added complexity. There are really no additional benefits. I could stretch and say the nitrous would give extra cooling, but it will still require a lot of extra tuning.
Actually, you would pretend like you are going to run 5psi only on the street, but that would last for the first 10 minutes.
