NOS anyone?
Okay, seems as if I have a pretty serious buyer for the Supra. So if everything works out I should have either a '01 or '02 S4 by the end of the month (or possibly next). I've been checking this board usually once per day and really never see NOS mentioned. It was pretty popular on Supras (although I never used it). How many of you s4 guys squirt the juice? It's definetly something I'll be thinking about. I know many people who spray on many different types of automobiles and all are "O.K." as long as you have a proper amount of fuel and don't use too big of a shot. On Supras a 75-shot is considered pretty safe when running 18-22psi w/ the stock turbos/stock fuel. How good is the fuel system in the Audi? What size injectors?

NOS = Nitrous Oxide Systems, not the same as N2O = Nitrous Oxide. Just FYI...
N20, "Nitrous", "Juice", "Squeeze", Nitrous Oxide are the generic name. NOS or Nitrous Oxide Systems is a company that makes the most commonly used N20 system.
Ahhh, not that I've used N20 or anything like that. =P
Pat, your turn...

Re: NOS anyone?
First off, unless you have just seen the movie "The Fast and the Furious", it's nitrous, nitrous oxide or n2o :-) NOS is a brand name.
There are 3 popular choices in port fuel injection nitrous setups; dry, wet or direct port fogger. A dry kit sprays only nitrous into the throttle body and uses the stock fuel injectors to add additional fuel (by either tricking the MAF or jacking fuel pressure up using the stock fuel pressure regulator). A wet kit sprays fuel+nitrous together into the throttle body. A fogger sprays nitrous+fuel (or sometimes nitrous only!) directly into each intake port, very close to the stock injector location.
I run a wet kit on a car of mine (not an S4) and it's a great way to add a huge amount of power :-) Nitrous Express sells a generic EFI wet kit that's adjustable from 50-150hp. I heard a rule of thumb when using nitrous, don't go over 40% of engine HP in nitrous use. Of course this doesn't apply to race cars, but is a good guide in a street car.
Don't forget to add in things like fuel pressure safety switches, timing retard boxes when spraying, window switches and ignition boxes (for the soft rev limiter).
Some of the companies that sell EFI nitrous kits...
Texas Nitrous Technology - www.texasnitroustechnology.com
Nitrous Express - www.nitrousexpress.com
Nitrous Oxide Systems (NOS!) - www.holley.com/HiOctn/ProdLine/NOS.html
Zex - www.zex.com
Those are all I could think off of the top of my head. Hope that helps :-)
