I have a ZC DOHC and i wanted to know what would be less hard on my motor to run a dry or wet shot nitrous kit?

probaly wet cause dry is more of an explosion

for a small shot they are about the same. I prefer wet myself.

i perfer dry over wet anyday....to me it feels safer

I like this topic, its like the breather filter and crank pully topics

eh, wet is always a little safer.....I can give you the scientific answer if you want.....

wet shot systems are less harmfull to the motor than a dry shot, because a dry shot system leans out the motor as a wet shot doesnt!

I would be interested in hearing this... I've always ran wet, but have been curious about trying a dry setup. Kinda scared about relying on the injectors to provide the extra fuel correctly, aka dry.

It shouldn't if its tuned right, I would think in a perfect world, a dry direct port setup would be the best setup. But I've not had too much experience with nitrous.

dry is way easyer to install too. i think it depends no how much of a shot you want a 55 or 65 dry is pletny safe. and the zex kit hooks up to the stock fpr so it wont run lean. but if you want a bigger shot your gonna need to add some more fuel hence the wet kit.

true "if it's tuned right", but 90% of people who run nitrous do have there car tuned for spray, and why spend the extra money to tune a car, when a wet shot and dry shot give you about the same hp gains. Now for the whole wet shot is safer than dry shot FALSE. both dry shot and wet shot are safe, nitrous oxide does not explode like in the movie the fast and the furios. nitrous oxide is safe do to the fact that it is a mixure of nitrogen and oxygen. The oxygen is what makes the mix affective, the only reason the nitrogen is in the mix is that it makes the oxygen safer to handle!

Ok here it goes, Ill make it simple:

Honda IMs are generally biased to the 3rd and 4th cylinder. This is ok for NA since the bias isnt too major. When you spray though it throws thing a little out of whack.

With a dry shot you are getting slightly more nitrous in those cylinders (this is why you often see those go first on nitrous 4s) Now with a dry shot you are getting that slightly uneven distribution, yet the fuel is being evenly dispursed via the injectors. So you get 2 cylinders a little rich, 2 a little lean. This is minor at a small shot (50ish), so it wont effect things too much. At a higher shot though it effect is more dramatic. Which is why you dont see 125 shot dry kits for small motors and they are not recommended.

Same scenario with a wet shot. Only this time your injecting fuel and juice together. So even though its not dispursed evenly through the IM, you still get a correct AFR, since they are already mixed before the IM. This leaves all cylinders with a better AFR. This works better than a dry shot, especially when you get to the 75-100 range. After that the IM bias problem gets bigger and you need to move to a DP shot to get the amount ingested to be equal.

This is a basic summary of things.
