Hi All

I've read threads on supercharging and turbo charging 964's but has anyone entertained the idea of a nitrous oxide setup?

Just wondering

Dear Bill,
The last pictures I saw of a 911 with Nitrous were very black. The 911 was dumped at the wreckers awaiting the crusher.
Ciao,

NOS is something for the "Fast and the furious" people, don't use it in your Porsche, It's a waste and a danger for your engine.

Nos is the latest craze with MG ZR owners. A modern kit gives a modest but controlled power boost. I'd investigate further before dismissing it.

I drove an Audi fitted with a 100hp bottle a few weeks ago .
It was fantastic, it really screamed thru the revs, but it did get a bit hot !!

I know of a biker in the UK who is insured to drive his blade with NOS. Apparently his insurance went up 1000%

Something to think about...
allot of cars running the one lap of america - were running NOS. Including the winner (7.0L corvette Z06)
the modern systems are pretty good as far as i can tell - although i have no experiance with them (yet) but i'm definitly looking at it as an add on to my one lap car.

ian c - u.k

modern systems are spot-on !!
with throttle percentage opening etc. they give an extra dimension .

the main "problem" is people puttin a 100bhp kit on , thinking its a cheap/reliable engine mod

as you are in effect cramming more air in like a charger , temperatures are bound to raise slightly

i designed a system to squirt into an intercooler as part of an anti-lag system ....... it actually reduced running temperatures !!!

It's not quite a bit more air, it's a bit more oxygen, like altering the oxygen/nitrogen mix we breathe. Whereas its a 20% oxygen atmosphere Nox takes the essential 20% an increases it in theory to 25-30% sometimes more.
This way the 14:1 ratio of air/fuel is allowed to have more fuel inside the combustion chamber and successfully burn it all.
It will result in bigger bangs, but if controlled properly temperatures to other components will not necessarily increase (think diesel) However Pistons take a bit of a thump.......and if not done properly will give the motor a pretty short life......

Not for me.

It's a cool idea IMHO. Not a good idea on a 911 since it isn't a drag strip queen, but could be fun just spurting around on the freeway late at night and squeezing a little bit...

"It's a waste and a danger for your engine."

I find it hard to believe how misunderstood Nitrous Oxide is by people that LIKELY don't, and have never used it.

I've had nitrous on two previous cars...we won't get into what cars they were, that's beside the point.

NOS, used in moderation can provide a stellar boost in performance, and is perfect for power on demand, it does not trash engines, it's the "greedy" users that trash their engines by leaning the mixture out more for more HP...just like the owner of a supercharged car making the pulley smaller for more boost or the owner of a turbocharged car upping the boost by adding a stronger spring on the wastegate or dialing it in on their electronic wastegate controller.

A turbocharged/supercharged car can run for YEARS without engine issues, if the owner keeps the boost levels within a reasonable range and watches engine temps, downpipe/EG temps while driving in "spirited" mode, i.e. at the track, on a hot day, etc.

Nitrous oxide systems can be "tweaked" just as well, leaner jets on the fuel side, bigger nitrous supply jets, heating the bottle...you name it.

NOW, IMHO, the Porsche engine was not exactly designed to have NOS used on it for the main reason that most are pretty high compression...which doesn't work well with NOS. The 964 for example, even employs knock sensors due to it's higher compression when compared to it's predacessors.

The 3.0 SC motor, the 8.5:1 or 9.3:1 versions would do GREAT with a 50-75HP shot, but the 9.5:1 "Euro" version would be pushing it...this is just "off the top of the head" values, and I have NEVER tried NOS on any of my Porsches.

The main issue behind installing NOS on your Porsche flat six configuration would be just that, the installation...as I don't believe NOS makes the injector plates to go under our throttle bodies, and for the efficient "Fogger" setups, which would incorporate nozzles in each of your intake runners would provide for even tighter quarters, with the space restrictions under the hood anyway.

I agree that one could meticulously endure the "perfect" installation of a tunable "Fogger" nozzle system, but that would require aluiminum intake runners and some fancy welding to incorporate the required "bosses" to accept said nozzles.

Then where do you put that DAMNED bottle??

My point is, don't dismiss NOS, especially if you really have no knowledge/experience with these setups, they are valid HP systems just as anything else that boosts HP to phenomenal levels.

Disclaimer: I'm not saying that anyone that responded in a negative manner to this post doesn't know JACK, but I'll stand my ground on the fact that if you don't know what you're talking about, read up and learn before throwing in your "two cents".

Interesting topic - and no posts since 2004....

Does anyone have any Real World experience with a wet or dry system on a 911?

Colin 90 C2

I actually have a wet system I bought from someone on Pelican who used it on his SC or Carrera.
It's a complete setup, but I have never installed it. I went on to buy more expensive power adders, also which have not yet been installed.

Interesting topic but haven't hear any news about Nitrous + air cooled Porsche. Have somebody manage to do that?

HEY JEFF!!!!!!

WASSUP???

How's life over in the waterpumper world?

Well said Jeff! How did those wheels that I sold to your friend ( I'm forgetting his name at the moment ) work out?
