Water/Methanol Injection

Water/Methanol Injection
I am looking to get this in the next week or two and i have a couple of questions.
1) Is there boost loss when using this(i read a thread about water injection that mentioned this)
2) Are there gains in power? If so how much?
3) Is this the most effective way of cooling in respect to boost loss ?

Chris - Get a dyno and get it tuned man~! You're throwing some serious **** at your car and you haven't even tuned it?![Confused](https://maxima.org/forums/images/smilies/confused.gif)
Don't worry about the drop in gauge pressure. That's a direct result of the cooler air taking up less volume, however colder/denser air means you'll make more power, if you *TUNE* your AFR to account for the leaner ratios you can run without detonation. The pressure drop is NOT the same as what people talk about with intercoolers.
Get the Aquamist system, it's worth it for non-intercooled SCs especially those in hot climates with 91-craptane fuel.

As soon as the headers are on this week i can get it tuned. + we have 93 octane down here bro

If not, I'd do that and get it tuned all at once.

No i forgot to tell you what happened. I had to bring them back for a refund because my books for school ended up costing more than i originally thought they would

Louisiana has good gas here. I went up to Colorado for a Ski/Snowboard trip over Mardi Gras week and wow 90 octane SH*T gas + high elevation = no power. Luckily I didn't bring my car but Frosty's 96 had fun going through the snow and highway 287. We do have a lot of heat and humidity but for performance I will take that over 90 octane and no air pressure.
Water/meth sounds like a really good idea but there are other things your need to get for your car first.
BTW It is too late so don't call me 2 minutes after I post this.

Water/methanol injection does lower cylinder temps, but it also slows down the burn rate of the fuel in the same way that higher octane fuel does. Slower burn rate means peak cylinder pressure occurs later and is not as high. This is just as important in preventing detonation as the lower cylinder temps. If detonation is suppressed, then boost can be increased.

If you search, this has been discussed a few times before.

Yea i have searched this topic. I went through almost every page in this forum but all the topics seemed to be on water injection only. I didn't know if methanol brought about any key importance in the setup

Methanol or any of the others you mix with the water just bump the effective octane rating.
I'd search the net for that info, but there is so much it's way more then you can absorb.

What the hell is that supposed to mean

Yea i am already changing pullies anyways since i am taking the blower of and changing the belt due to a oil leak
