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.LegendC said:
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!
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.
