Anyone crazy enough to try Nitrous??

[JABM]

Maybe I'm the only one, but I think this would be one of the perfect cars to do it to. Being turbocharged, the Nitrous will act as a second intercooler, and of course, the Nitrous will have its usual oxidizing effect. Any thoughts?

Its been done
There should be a response by someone with nitrous on a 944 turbo,but most people will refuse to use it,for obvious reasons,but than again theres some that just wont because its a "porsche" but thats silly right?

[arnebret]

Blurg, that would be terrible. Nitro on a 951! What the hell will that feel like. I know nitro works very good, but it has to be done good and i can't imagine the 951 suitable for this (ever looked under the hood ) This car, in it's normal setting, is already pushed to quite a few limits, but can easily be upgraded. I can already see the headgaskets flying straight through the window. I really like to hear some experience with it, but it seems awful to me.

I want to run nitrous soon,just waiting for a nice turbo to acompany the go go juice

I think the 951 must be a decent car to add nitrous to because it is one of the few turbocharged cars that Nitrous Oxide Systems (NOS) makes a prefab kit for. I still may be crazy, but I think it would be a fun mod.

Jordan, you might be nuts anyway. But if NOS makes a kit for it, I can't see it as being that unsafe for the car. I don't really beleive that the 951 engines are really all that close to their limits from the factory, as if well maintained seem to live long, and there seem to be plenty of them out there with high hp. The majority of the danger of Nitrous is in the users finger anyway. Mayeb do a wide fire ring head gasket, and o-ringed head when you you do the nos kit, if you decide to. just for extra security.

[NineFifty1]

Nos does make a kit for our 944 turbos,odd huh?
I dont have the part number with me though.
Anyone else have any interactions with nitrous with 951's?
Ill keep you guys in formed when i run my kit .

nitrous man, I really would like to know more about people's experiences with nitrous, anyone?

[rick13]

is there a way to have nitrous hooked up to where when a certain rpm is reached that the nos would shut down and let the turbo take over. because let's face it, these cars are dogs until about 3500rpm. i know one of you guys have thought of this...it would seem if it can be done manually ( with some serious concentration, and a conveniently located button ) it could be monitored electronically.

what do yall think?

You don't want to hit the NOS button UNTIL about 3500rpm unless you want to turn the engine into a pile of little pieces.

[89-944NA]

Chally...nitros under 3500rpm would make someone a nice melty looking door stop, wouldn't it? lol

[chally72]

Had a little 1965 mustang fastback with a 260 v8 in it a few years back. Traded a hood scoop or something for a 75hp shot system. Must've run three or four tanks through that stock little engine with no problems. It was almost a torture test. Compression checked it regularly, and it never dropped.

I let a buddy drive it one day, and he punches the button at 2500rpm and kablooey, pieces everywhere. Lesson learned: Nitrous master arm stays OFF with other drivers.

[rick13]

alrighty then. i got that message loud and clear. so, no nitrous. (especially below 3500 rpm! lol)

[Lawrence Coppari]

Why is nitrous at low rpm harmful to engines? Detonation?

Usually the guys that use NOX on turbo motors use a 50 hp shot to help spool the turbo and then disengage the system when the turbo kicks in. Mostly drag drag racing. I would not want to subject my t ranny to that kind of abuse. They make all kinds of kits and controllers for NOX. You can control it based on rpm so yes you can engage at x rpm and then disengage at x rpm


At low rpm in addition to drive line shock, you have to much timing advance, with NOS you have to back off the timing X degrees per 25 hp or something similar. A built NOS motor is usual a N/A motor with thick crown pistons and retarded timing or a NOS controller to automatically control ignition. That is the car would run normal ignition advance when not on the bottle and retard the ignition advance when on the bottle.
The 951 internals are probably good enough but the driveling and timing advance would be an issue.Not something I would do. Water injection or E 85 are much better options on a turbo motor.
just my 2 cents.

[v2rocket_aka944]

i have seen a cleverly done nitrous system on a 951 that had been run for a while without issues. 2 BIG tanks in the back, wet setup up front. bet it was a hoot, i think the car blew its turbo though.

Instead of NOS, You should try meth injection. I put it on my 930 motor and it was great. Lowered my A/Fs you can feel the difference when it kicks in and I did not change my tune at all.

I gave my son the 951 and I am thinking about putting it on that. You can just tap into a vacuum line and run it off boost. I start it at 7lbs boost and get full spray at 12lbs.
I use a 50/50 mix meth and distilled water. It cleans the motor and bumps up the octane to about 115 from 93.

I am using it more as a safety thing on the 930 because of detonation on the CIS but with the 951 you could probably tune the car to run 20lbs. You can also run more timing.
I think it would be cheaper than NOS also.

Just a thought. John

I've come to view nitrous oxide injection as somewhat of a "cheater" system. That's because it will "time out" on you before very long, and then you are not going to look too cool when you are that far back in someone's rear-view mirror! And this would seem all-the-more-so on a p-car. But it's not like I would turn down an offer of a ride in a p-car that was so equipped.

Hmm, I'm now wondering how well a "mini" shot of it into the exhaust pipe that feeds the turbine would work for the purpose of spooling up a large turbocharger faster and (especially) at a lower rpm than would be otherwise possible. With that you would not see a 50, 75, or 100hp increase, but you would probably get 20X or more time out of the bottle before it runs out. +

[chally72]

!!!!

Now you want to inject nitrous into the exhaust after the head?!!

Wouldn't shots of compressed air serve the same goal you're thinking of? Without the risk of massive fires/explosions?
