I'm sitting around a bunch of so called mechanics (shade tree) and the one guy suggested to me that I should put Nos in my ride...I suggested to him that he should stick Nos somewhere else....My thing against Nos is, and someone correct me if I'm wrong, that it will clog up fuel injectors and or the fuel filter with extensive use.....It will also cause some harm to the performance of the engine, in turn which will cost some bucks to fix....I told him I'd rather wait on the headers........His only argument for Nos is that I will have a better chance in racing some of the more faster cars that I had problems with in the past(Lex LS 400, Seville, 5 Series BMW..) and with preventive maintenance I could catch these problems that I named earlier........Holla Back, I really need to hear from my forum brothers.....
Well if you insulted that guy, it best if you came up with an apology, because NOS will NOT Clog anything as Dave C already has mentioned. ITs a gas, not flamable, but an oxidizer. Esecially its A cold burst of thin air.

On a well maintained Legend a 60 shot will, do nothing but add ponies. A 70 shot has proved to do no harm either. its the 100+ were the Exhaust gasses get so HOT that they can backfire in our retardedly designed LOG exhaust manifolds, with small outlet ports, so small that the gasses cant escape quick enough. End result is Boom.

Im getting ready to shoot 100 shot direct port on a ported and polished type II among many other things, im seeing 12's



60 shot nothing has to be done youll get about 40 extra WHP
just make sure you keep matinence on you ride.

You are throwing around some good terminology but I don't think you understand a couple of fundamentals.

100hp boost of nitrous vs 100 hp boost of turbo

Intake temperatures will be lower with N20 becuase of the cooling nature of an expanding compressed gas. Turbo's will always heat the intake charge, even with a very very efficient intercooler (80-90%) over ambient temperature.

Lets talk about compression correctly. Compression is the ratio the fuel\air mixture is compressed on the compress stroke. Legends have a relatively high compression, thats how we make a lot of horsepower NA. When you add any kind of boost you are putting additional stress on the engine to compress the denser intake (fuel\air) charge. So in out 100N2O vs 100Turbo example both are putting nearly identical stresses on the motor. Assuming neither increase in power goes over the threshold the motor can't handle ie some internal breaks....which is better for longevity? Always having that 100 HP or only when you need it? Remember you are adding stress on the motor...

Last lets talk about what ususaly breaks a good motor. Running lean and pinging. On a high compression motor what is more likely to ping...a hotter less dense charge, or a colder denser charge? Even at the same "boost" or increase in PSI the colder charge which is what you want. A highschool chemistry class will teach you all about the gas laws and will explain how all this holds true.

So back to the application of this knowledge to our cars. DV8 mentioned that the hot exhaust gasses can't escape our ****ty headers. This is a problem ALL FI setups would face, turbo would need a new exhaust manifold anyway so this is almost moot. With N2O the kit pretty much manages the fuel setup for you. Its only running at WOT so there is little variability in its configuration, it just raises fuel pressure when active. With a turbo or supercharger you need true engine management. The fuel needs are different at 1\4, 1\2, and WOT so you need a complete spectrum of tuning.

So alas, when asking a question about the only from of FI AVAILABLE you try to chop the N20 users up. Last I checked the fastest Legend was on the laughing gas.

So, is 100 shot the ceiling or should I try to find a 75pill when I have my ZEX dry kit installed. Thanks!
best explination to date, I'd say that 85 shot or lower is great for anyone at WOT pusshing 100 your going to play with a 50/50 chance.
I have some serious mods to my internals now so im not to worried about a 100 direct port shot which is spraying equal amount of fuel and NOS were as my [email protected] was with a dry 85 shot and letting the fuel computer compensate for fuel, which most Legends do surprisingly very well.

ranger....to each his own, if i ever caught you on the freeway driving your car i would remote the bottle opener and push the button, as you watch me fly away not being able to catch up, maybe then you'll reconsider a 6k+turbo kit and spend 1000 for a good Custom NOS Kit.
