Meth Injecton Question
Hopefully O-cha reads this, am sure he knows. Most shops selling meth kits are closed at this time of night and am itching for an answer to my questinn.
I was advised by the guy who did my v2 install to make sure to avoid putting the injection nozzle before the sensor on the IC charge piping. The mechanic I was referred to said that the sensor is a pressure sensor, and would not be shorted out or harmed by the meth. I am wondering if it is detrimental or not now that I have two varying opinnions. Also, isn't there only a little space after the pressure sensor on the IC charge pipe? So where to mount te nozzle? Pre or post sensor? I am worried that the meth spray on the sensor will eventually eat away the plastic. Oppinions anyone?

I told you VERY COMPLICATED CALCULATION went into that.
It should not harm the sensor, but it does not really matter as you don't really have a choice to put it after it.

BTW I would hold off on meth until it can be done right. Which will probably be never.

Right. I think I am just going to get it done on the SP Stage 1. I am waiting to pull the trigger. My shopping cart is filled and ready to go .

BTW O-cha, why wold you wait for it to be controlled via piggyback if Shiv stated he isn't going to do it?
I don't think there is any harm at all in using meth injection unless it burns out my sensor, which now I doubt will happen. Also, someone I know is spraying nitrous before their sensor and is having no probems.

So is my way to go about it kosher? What are you waiting for?

The kit should work, no? What would your projected gains be? I am estimating 10 - 20whp(including the % torque increase)? Should I expect more or less? Also, if I threw in race gas, I would gain even more, correct?

*sigh* I bought it. At worst, it is going to help give a denser charge and increase octane of gas somewhat. Will help with the back to back pulls.

[/U] i am interested in possible water/meth injection only because of the 85 octane "super" gasoline they have here south of the equator.[/U] if water /meth can raise my octane to say 91 (from 85) that would be something. o-cha, is there any way of knowing how much octane can be gained (use 85 octane as a starting point) with a good water/meth system?? lastly, some guys say do not go near meth because it is a no no for our car long term reliabily.....what do you think?? thanks

There is no easy answer and will be application specific. But you also have to ask, what is the desired benefit of the meth injection; to gain power or to gain consistancy. |

2/ at 8,500 feet (thinner air), methane will cool my intake charge = denser charge = more power. what did captain kurk (star treck) used to say... ...oh yeah, ¨I need more POWER scottie.¨ i assume my 2 assumptions above are correct.... so for me it all boils down to how safe is the chemical reaction of water/meth injection for our motors ??? this point was debated on another thread, and some well known minds could not agree. fwiw, it seemed like the edge in that debate went to ¨I would not do it, let others do it first... and only after an extended period of time would it be known how safe it is for our n54.

too many questions. Umm about the two people making kits, I don't believe it will be n54 specific. I think it's going to be for all engines like the n54 who can't properly control a spray by boost. I think they will use something to tap into the injectors to determine spray like I've been trying to find. Probably something like what aquamist has but less complicated and hopefully less expensive.
As for the octane, I've heard meth quoted as between 110 octane to 130 octane. Not something I can really test myself. You also need to realize just because it's say 115 octane does not mean your going to get the average between the two. You might get a few points of octane at best. The best bet to find what it's doing is dynoing and logging ignition timing and intake temps. But that still wont tell you what octane your getting into, that's just not going to happen.

There are a few threads here about meth injection, 1 that i started when i did mine. Where do you get off saying it cant be done right? Please do not speak on which you do not know. -deck |
