The problem was not the NOS alone but the combination of USED tires and NOS...never a good combo.

I think that wet kits are best used with intakes designed for wet flow and forced induction applications which the 996 does not have.

The association claims that prolonged use of NOS can lead to catastrophic engine failures, particularly at speeds easily reached on German autobahns, and that in Germany nitrous oxide is an illegal fuel because it is unable to be homologated under Germany's stringent TUV test methods.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.
37 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

spend the money saving for the turbo conversion or the supercharger kit if you really want to do stuff that will put out. That former thread about the modified giac chip sounded pretty good too if you are going the na route.
What makes me more interested in this is the fact that I can find nobody that has done it, lol! It's quite funny to me as it is very common in the Corvette and Viper communities I come from.
I don't really want to supercharge as if I was to spend an extra 10k on my car, in honesty I would just buy a Turbo for the extra money. I also like spending my cash on exterior mods (for example I am changing my front spoiler due to hitting a dog, I think I will go turbo front)
As for the N20, I has it on my vette, used it maybe 10 times, and enjoyed just having it there if I needed / wanted it.
I love the way my 996 drives, it's the best car i have ever owned hands down, however the power is not what i would like (I feel most 996 owners are in the same camp) and since there is very little you can do to add another 50 - 75hp NA I think N20 is a nice cheep easy and almost risk free way if done correctly.
An interesting question that I have thought about myself!
Actually, if kept to reasonable levels, nitrous it's a much easier, less expensive, and less trouble-prone way to reliably add HP as opposed to aftermarket turbo kits.
Let us know if you find anything. (Well, at least let ME know - I don't think you are crazy or misguided!)
I found this in the July 2003 issue of GT Purley Porsche...
NOS NO GO
The Association of German Automobile Tuners (VDAT) has warned against the fitment of aftermarket nitrous oxide injection kits. The association claims that prolonged use of NOS can lead to catastrophic engine failures, particularly at speeds easily reached on German autobahns, and that in Germany nitrous oxide is an illegal fuel because it is unable to be homologated under Germany's stringent TUV test methods.
-----------------------
The only thing I got out of that was 'prolonged use' which in my book means you can use it...
Well I don't plan on using it at 170+ lol!
I KNOW it has to be safe, the key is what kind of a shot is safe... <img border="0" alt="[crying]" title="" src="graemlins/crying.gif" />
back in the ricerocket days, we were always warned never to squeeze on the freeway unless you wanted to melt your heads...lol
i wouldn't go more than a sneeker bottle of nos on a porsche just to be safe. 20 shot would be good enough as this car is already fast and you just need a quick boost to hang with a turbo.
I've had nitrous on a number of cars, and my experience has generally been that the better a car is, the better its engine is, and thus the stronger and inherently more reliable it is...that said, Porsche engines are damn reliable, and the turbo cars continually prove that the factory mills can take a serious amount of massaging before having problems - confirming a serious bit of over-engineering on Porsche's part(god bless 'em)...see any of the hundreds of 600+ hp 993TTs and 996TTs on the street(s). In the end, my '78 930 lived for 40,000 miles on almost daily dosages (60hp at a time) of the bottle...I'm seriously considering spraying my 996TT. I say put some cold plugs in it, gap 'em tight, run good gas and hit it 60-100. Good luck and enjoy!
you're right about the bigger and better, but from what i heard about the regular 996 engine it can't even handle a blower what more a shot of steroids.
for what the engine costs if it blows i don't think its worth it to have a cheap thrill on the porsche. I think used engines still are around $5k if you think you can risk these expenses, better do it now and get the supercharger which at least someone has R&D'
Cool!!!!
Let me know how this goes. A 60 shot sounds like an excellent choice. I was thinking 75. Which manufacturers kit is this? I was looking into the NOS PowerFogger but it's a wet system and I'm a little afraid of that since if there was ever a backfire through the intake during nitrous injection, the entire intake manifold would blow. Dramatic but expensive!
A zex Dry kit.
I am having a stereo system installed at the same time, lol, so my power to weight ration will be the same with the N20 on as it would be stock, lol!
It my engine blows, I will be the first 996 with a single turbo supra engine swap done. <img border="0" title="" alt="[Wink]" src="wink.gif" /> lol!
A dry kit definately sounds like a good way to go. Be sure to post pics of the install. I always like to see people do new and differnt things to their cars. Maybe it wil be a new trend? Does this kit activate at WOT or is it swith controlled? I would hate to roll up to a Porsche on the street and see a shot of No2 blow out of the purge valve <img border="0" title="" alt="[Eek!]" src="eek.gif" /> Good luck.

Good luck, but personally I think you will damage your engine. The M96 is pretty much maxed out (3.8 will be about the limit). Many aftermarket companies have tried to do forced induction and have blown engines. TPC now has a SC but that won't be out for a bit, When outfits try to TC it they have to do some major engine strengthening. If you do nitrous I would do wet before dry.
A wet system seems a little excessive for a 60 H.P. shot don't you think? I think that wet kits are best used with intakes designed for wet flow and forced induction applications which the 996 does not have. If this were a carburated car then I would say go for the wet kit but EFI cars are designed only to flow air and nothing else. A dry kit is much simpler and safer for this application.
-Andrew
nitrious on a 996 defeats the purpose of the whole car and makes me laugh at you. Stockton I mean compton says it all. Don't be a moron. If you want to squeze on something don't pay the money for a german car. buy some japanese pos and pay for the build up and enjoy it.
Do they require a mullet before installing NOS on a 996?
I think you bought the wrong car if you're looking for this. That's just my opinion of course.
Gimmie a couple of months, the mullet will be in full effect...
Trying to decide between that style or the 2Fast2Furious style
Either way I think the results would be interesting to see...
contact v8huntr. I think he had nos on his car (996) before he put on the supercharger. if you're from the viper community I'm sure you've seen his viper... it's a red gts with twin turbo chargers AND nitrous AND propane running 1087rwhp.

Update...
Just to let everyone know. I tried a 50shot, ran it for awhile. No problem.
Seems safe with a 50 shot!
... Then I tried a 75 shot and blew the dam thing
Whoops!
Actually, I think it was only a few months. Post #34 in this thread:
https://rennlist.com/forums/performa...eir-996-a.html
He first asked about it in July and posted the sad aftermath in October. The part I like is how it survived for a while on a 50 shot, so that amount must be OK.
Too bad he didn't post any pics of the demise ... could've been spectacular.
These guys are a hoot to read about... Always a great laugh seeing someone do something risky and watch him fall on their face. Kinda like the entertainment of some bright jackass eating a ghost pepper. All acting like they're a stud and "it doesn't hurt"... then moments later the toxins react with the body... and then they're crying like a baby while everyone laughs their butt off. hahaha
Well, my advice is that if these guys want to taste the wine for poison, more power to them!
Actually, I applaud the explorers and risk takers. That's knowledge gained.
The timid settlers watched the scouts to see who came back with arrows in their backs. That's how you knew the direction you didn't want to go
In all seriousness, while some ideas are patently stupid, other ideas are less so. It takes a few innovators to explore the limits. How many motors did Jake go through developing his M96 engine program? Charles on his cylinder relining process? Many others have developed the products and processes we use every day. Had there been an internet back then I'm sure the forums would have had the same comments.
I'm sure a forum discussing the Wright brothers and their attempts at flight would have been a quite amusing read....up to the point they actually flew.
