Latest from Honda Tuning on Nitrous:

Hello all! I'm new to the board, and imports, having been drag racing BB/SB Chevrolets for the past 20 years. I've been reading all of the posts about N2O systems and usage; I've got a few comments to make, that somewhere down the road may save someone alot of money:

1. NEVER, EVER use any type of sealant (teflon paste OR tape) on the nitrous side of a kit (like "Keith" at Honda Tuning shows in the diagram)...unless, of course, you have an extra short block lying around ...ALWAYS use a good N2O filter in line, just before the solenoid.

2. The argument that installing a single NOS nozzle into the air stream ahead of your throttle body may disrupt or impede some cylinders from getting the proper distribution is not accurate; I've run single nozzle "dry" systems on cars before, no problems (especially with a closed loop "return" style fuel system). NOS distribution is critical, but not nearly to the degree of horsepower levels you guys are reffering to. I will however, attest to the fact that a fogger (direct port injection) is ultimately the best distribution, most hp you can get...but it is also the most dangerous (in terms of tuning). If it's available, get the fogger, bottle heater and bottle pressure gauge, and a little thing called a "Hobb's" switch for higher (EFI) fuel pressure applications. If you lose fuel pressure, it will save your engine.

3. It sounds like there are some REALLY sharp people on this forum, and If you're really interested in N2O performance tuning, buy the book (I'm not the author, BTW) by that title....it has helped me tune my NOS systems, fuel systems, and calculate BSFC, which the latter two are tremendously important.

 

This just came in from Holley/NOS...

The new nozzle will only work on Bosch style injectors. It will not work
with the Keihin injectors.

Thanks, NOS tech dept.

so I guess that idea got squashed

OK....those who know me know I believe in getting the "knowledge" and then coming here for the "wisdom". If you are serious about charging the car get the knowledge. It'll run you about 20 bucks. If you are familiar with the Honda Engine Tuning series here is the authors take on Nitrous. This guy is THE Guru of the 13B motor and much is applicable to the F20C also:

Good call, Utah....The author most certainly knows spray....I've read his other books. Believe ti or not, most of the SA books are directly applicable to real world tuning.

 

Also remember that when running a wet single fogger setup some cyliners may get more nitrous, but the same ones are also getting more fuel.

What about that? It would be cool to have a hidden system. However it is dry, so maybe no more than a 35 shot? And tuning?

 

I just bought a 75 shot dry system that I plan to have AEM EMS inject a larger fuel map when activated. Though the Injectors is a nice way to enrichen each piston equally. The Dry system is also less intrusive. I am going with a Dry sytem set up and will probably move up to a 100 shot. Be advised that Dyno tuning is a must for proper air fuel mixture ratios.

 

Wow, what an old thread.

 

Honda s200vtec,

are you utilizing the aem ems to activate both at the same time?? is the aem unit capable of triggering the nitrous solenoid?? the dry setup actually does trick the FPR to increase fuel through the secondary solenoid that comes with your dry kit.

also speaking of proper mixing, 100 shots dry is a lot when being injected through one single nozzle. Unfortuanetly at times the distribution will not be equal throught the runners.

just a thought.
