Can both be run a fully stock car?
What are the advantages of one over the other? To run nitrous, methanol seems to be mandatory running on pump gas (91 or 93 octane) but what about when you use 100 unleaded octane?

They are 2 different things. Comparing the two is like comparing drag radials to an intercooler.
Nitrous will wear on the engine, it will be sure to give you more power as well. Methanol is more of a safety mod that gets you more power either via the tune (supporting the tune to where it could not boost without the meth) or via advancing timing and cooling through efficiency. Methanol injection is one of the only mods that can extend the life of your engine and will certainly not add wear to it. You can run methanol on a stock engine no problem, I will leave the Nitrous answer to the experts. CM |

I'll leave the slicks for you guys in the warmer weather. I'm up in NY but wanted to have that extra kick when someone pulls up next to me from time to time. I don't want to want to stage my car to stage 3 and then add meth and nitro. I wanted to leave my car as is, and just add methanol & nitrous.

Nitrous acts as a fuel for the engine.
Meth acts as a cooling agent for the intake. Meth is good for our engines. It cleans the valves and it cools the IATs. Nitrous is like a bomb waiting to go off. If the bomb goes off at the right time then you're happy. Sometimes, the bomb goes off at the wrong time and you will be sad.

Methanol is fuel and also does cool charge temps as well. People that say nitrous blows up engines should also say turbos will blow up your engine too. The car could care less where the cylinder pressure or O2 comes from. Nitrous isn't even flamable. The whole analogy is almost Fast and Furious funny. |

You might not like my statement, but I do. The reason why nitrous gets such a cringed feeling around here is because there are many that throw on a tank of nitrous without knowing what they are doing, and they have just made a time bomb for their engine, especially when people get a 25 shot for their N54 thinking that it is a 25 shot when it actually is a 100 shot or more.

Clearly you have a bias which is ok, but your information is simply not even remotely accurate. How is this different then throwing a tune on your car? Some run a map that is not appropriate for their mods. How is this different than throwing a flamable fluid in your trunk or in your windshield washer tank? What makes something safe is the safety mechanisms... period. Any mod done wrong is dangerous. Last edited by Former_Boosted_IS; 03-22-2010 at 11:41 AM.. |

Thanks Mike. I was looking forward to have this setup before the summertime. It's my last year with the car. I think I'll pass on nitrous then this time around for the duration of this car. I'll try to educate myself as time passes by as you guys from both party's are working wonders and posting progress on the forums.
Thanks again. ![]()

Going back to my "acting as a fuel" statement. I agree with your statment below: It allows you to add more oxygen for the combustion process But, I'd like to tell you where I'm coming from. If a fire is started in a room then the fire will burn until all of the oxygen is consumed in the room and then it will try to suck as much oxygen through the cracks as possible. In this case, the oxygen is acting as a fuel for the fire. No oxygen means no fire. If a door is opened then all of the oxygen from the outside is consumed and boom! Nitrous acts as the same in the engine but it lets even more oxygen feed the fire. Quote:
I have a mixture of 50/50 meth/water in my windshield washer tank which is not flamable. Compare that to your nitrous tank in the trunk which is under pressure. And, common man...you cannot compare throwing on a tune to putting nitrous on your car. How many people here have put on a piggyback and have wired it incorectly where they threw CELs? Or, how many people have had their boost too high which triggered limp modes? Correct the wires, reset the codes and then you're fine. It's so easy to find a used kit off of ebay, and throw it on your car. I can see it...Someone sees a 75 shot kit so they get it thinking that they're adding 75 hp to their N54. I think what you have on your car is more promissing and makes me feel a little more comfortable but time will tell. No matter what, it looks like you've done your homework.

All those safety features that you have implemented on your car seems to be covered by the Procede tune being that its able to read all those Canbus data and convert it to a safe trigger to turn the solenoid for the NOS! Thats one reason why I am so looking forward to getting it, and I would not need to spend for all those extra precautions that you have on your NOS system...It would have been too much money for me! ![]() ![]() |
