WET VS DRY
yes, an age-old problem. Heard this weekend at the Waterford Corvette Show - some drop -dead cars: love those tricked-out '58 to 62's - that wet nitrous is a problem for the C5's and there intake manifolds. The view was that the dry system into the air intake was safer and just as effective. Any thoughts on this matter??
Again, Waterford was great and look forward to GM Tech!!! :auto:

Re: WET VS DRY (Irish Whiskey)
i'm new to this but putting nitrous on my car very shortly. i'm going with the NOS dry system because i have heard that it is safer and simpler. with the dry system you spray infront of your maf sensor and the computer reads the extra oxygen and the cooler air and supplies more fuel, with the NX wet system they have a device that replaces your throttle body that delivers the N2O and the extra fuel, its my understanding that you need to be carful that you have your fuel to nitrous mixture right, plus with a wet system there is a possibility of the fuel puddling in the intake manifold which could cause it to backfire and destroy your manifold(its just plastic) and i would imagine a few other parts. The advantage to the wet system is that you can run up to a 150 shot on a stock engine versus a 100 shot with a dry system(don't know why this just seems to be the consensus) This is just the short version but there is plenty of info out there, if you don't get a big response here try the FI/nitrous section :seeya

Re: WET VS DRY (Irish Whiskey)
I've had a couple of cars with nitrous and from my experience is that wet kits are better and safer for the motor. When you go with a dry kit you run the risk of running lean if you don't increase the fuel. With a wet kit you increase the fuel going to the motor. If I were going with nitrous I'd also go with the Holley Aluminum Intake. Incase you backfire you won't blow the plastic intake manifold to pieces.

Re: WET VS DRY (ne14puertorican)
dry kits are harder to tune since you are relying on the computer to add fuel. Wet systems are easier because you are adding fuel when you spray. If you have any questions please let me know.

Re: WET VS DRY (ICULUKN-C5)
With the dry system you are really taxing the stock fuel injectors at 100hp, if one is a little dirty you are going to go lean in that cylinder.
As far as the computer goes, either way you should have it dyno tuned while you step up different levels of hp to make sure everything is behaving as it should.
I suppose it is possible to puddle fuel in the intake, but if you are moving air through the intake it shouldn't happen. The only way I can imagine it would puddle would be if you shut the engine off mid spray. The manifold isn't designed to get sprayed with fuel, but you aren't spraying at part throttle or into a cold intake. It should vaporize and be burned at full throttle IMHO.
The only advantage I see to a dry system is being able to hide it easier. The wet kit basically guarantees the proper mixture of fuel and N2O, and is very safe when used with a FTPS, monitoring fuel and N2O pressure, and a window switch. I would also suggest running series N2O solenoids, and parallel fuel solenoids. With all the proper precautions it should be extremely safe.
