"Good work guys! All this talk about HP/$ is nothing but "mental masturbation". Some people "know the price of everything, but the value of nothing". The only feasible option to make those kinds of HP gains is building a stroker."

Any 928 should be completely safe running a 125 shot, and there are two posters here who've safely run 75 shots for extended periods.

Christ, i know a guy that runs a 200shot multi-stage on a 2.3 liter Mustang 4 banger.

Nitrous operates on EXACTLY the same principal as turbo or SCing does. It packs more air and fuel into the cylinders.

It is no more unsafe than SC/Turbo, and has the benefit of massively reducing the intake air charge, thereby greatly reducing the chance of detonation.

A 125 shot, which would cost about $750 installed and filled, will get you right around the same power level of this kit, and that's a fact.

Unless you forget to turn off the bottle heater like this joker...

Yet there must be some reason Mercedes Benz, Porsche, Ford, and Audi continually put twin turbos or superchargeres on their cars instead of Nitrous. In comparison to what similar kits cost to make the kind of power a 928 can have, the kit is inexpensive, it's frugal. It is cheap.

This would make a shot of Nitrous "Ghetto".


(edit)

Allow me to clarify. All things being relative the supercharger kits these private builders have been coming up with are cheap in comparison to other more corporate tuners or factory offerings for other vehicles. Even in the Lamborghini world there were a few guys using Nitrous set ups until a few tuners bit the bullet and developed reliable twin turbo kits. Guess what? Those nitrous kits are coming off the cars and two turbos are going on.

It's just sexier that way.

Wow, is that true, that nitrous is working by the same principal as SC. I always thought that nitrous oxide kind of replaces oxygen in the chamber, and breaks NO2 to N and O. It is like driving in a very oxygen enriched atmoshere. But, I am really not sure about how N affects the engine. Another thing about nitrous is that it is alot more rapid then SC for example. So, it is a lot more rough for the drive train.

Nitrous is not legal for use on US pollution controlled motor vehicles, and you have to re-fill the tank as needed. I would imagine they're the reasons.

"This would make a shot of Nitrous "Ghetto"."

Ghetto schmetto, as long as it works.

BTW, during WWII the Luftwaffe made extensive use of nitrous injection to enhance performance of their fighters.

I would hardly call the Luftwaffe 'ghetto'.

Yep

"I always thought that nitrous oxide kind of replaces oxygen in the chamber, and breaks NO2 to N and O."

A nitrous shot adds additional oxygen into the combustion chamber, and the nitrogen cools the fuel air charge massively.

"It is like driving in a very oxygen enriched atmoshere."

So is a turbo or SC.

"But, I am really not sure about how N affects the engine."

It just cools the air charge, which of course, is extremely helpful.

"Another thing about nitrous is that it is alot more rapid then SC for example. So, it is a lot more rough for the drive train."

True to some extent, however, nitrous is either off or on, unlike a turbo or SC, which imparts an additional load on the motor any time boost is built. In the long run, one is no more 'hard' on the engine than the other IMO.

Carl...meant to ask you Have you done an install on a GTS yet? Details???

mulik51

What I meant, is that the N which is a byproduct of breaking NO2, as of what I know is kind of caustic. So, I don't know how that affects the engine.

Klim
P.S. Actually a lot of planes used NO2 in WWii. Mustangs did. I think ILs did. That's where it came from.

Kaz

Yes, extensive use until what? Anyone, anyone? Jet aircraft were developed.

m21sniper

Nitrogen is not caustic, it's in every breath of air you breathe.

If it was, we'd all be in serious poo-poo.

m21sniper

"Yes, extensive use until what? Anyone, anyone? Jet aircraft were developed."

Nitrous would also work on jet engines if one felt the need.

Nitrous fell out of use in aircraft after WWII when the transition was made to jets, but i'm sure some recreational and competitive fliers still use it.

Mark Kibbort ran it for two seasons in his 928, and all kinds of people(both professional and amatuer) use it in all manner of NHRA classes, and for other 'recreational uses'.

Well, touch some of the liquid nitrogen(that's the state it is in the bottle) with you hand.(Don't do that, that's just an example

Sharkskin- Heh, we've all seen blowers literally explode on NHRA drag racers as they went down the strip.

Turbos can cause fires as well because the turbine section gets so hot too, and if a compressor turbine blows up, it's like a grenade. Rare, but it can happen.

Anytime you're working with an engine, there is definitely potential for catastrophic failue....even N/A engines.

"Well, touch some of the liquid nitrogen(that's the state it is in the bottle) with you hand.(Don't do that, that's just an example"

LOL, you wouldn't want to do that- pure liquid nitrogen is like -180 degrees F.

m21sniper

At any rate, we're hijacking this fella's thread, which is not nice.

No more nitrous talk from me.
