50k miles of alcohol injection and no cracked pistons! Cheap alky kits exposed.

Corn.

I don't think Alky injection is terrible, but if you can run corn, do that.


Truf, see last sentance of my post suckas ;)

Corn.

If a moderator deletes your post because it adds nothing to a pretty tech specific section, why repost it? It didn't accidentally get lost man ;)

Sure it does. It's a valid alternative. And I personally don't see why someone would opt to spend all the time and money on an add-on alcohol injection setup when we have an abundance of alcohol laced fuel at our finger tips here, especially considering the risks, consequences, and chances of failure as was shown in the original post.

Corn, a viable alternative. Only thing you need to worry about is changing mixtures during the seasons. But that's not too tough to work around, just don't tune your car on the edge, pay attention to when the blends typically change and throw on a different fuel map if you so desire. Easier then buying and filling up a meth tank every few weeks.

But I'll stop, don't wanna stir that pot anymore :)

Good luck playing with meth, but I'll just listen to the commercials I see everyday telling me Meth Just Isn't Worth It :D

Thanks for not listening, I really appreciate it.

Just to clarify, this discussion is not about e85 versus alcohol injection. I said it in the first post, all it does is dilute the discussion and really is not the point I'm trying to get across. E85 is great, but not everyone can get it easily, not even me. I've said it 1000 times before, why it needs to get beaten to death just because we live in MN, I have no idea.

Back on topic, here's a great article that Richard @ Aquamist linked me to:

I guess one thing I am always scared of is how do you ensure even atomization/distribution of Meth across all cylinders? Most meth failures it seems are the piston/cylinder furthest from the throttle body...is this not a problem with all meth kits that aren't direct port? I guess I would feel a lot better with a nozzle on each intake runner but maybe that is excessive and I don't know enough.

It just seems that last piston always bites the dust.

[scheides]

I wouldn't say that's true from what I've seen but it surely seems probable.

The way around this is with precision, mentioned in first post. Always spraying at high pressure ensures that the alky/water mixture is always fully atomized. Then, making sure you have your injection point a ways upstream from the throttle body will ensure that it mixes evenly with the air flowing into the engine. If its fully and evenly distributed in all of the air going in, it should go to all cylinders equally.

If you use a PPS kit and it doesn't always spray at full pressure, then yea, you can surely get alky in some cylinders and not others, especially right when the pump kicks on...which incidentally is right during boost onset and then peak torque...see how that could lead to the pics mike posted? Yup.

[Murlo26]

Like I said I don't dislike Meth :) It just worries me a bit and the setup is tough it seems.

I would be pretty comfortable with a nice Aquamist kit (honestly the only brand I would consider) and a direct port setup like I mentioned but yea I see your point on it fully mixing with air.

I guess if it wasn't possible to fully mix it with air, any intake manifold wouldn't work right because the air wouldn't make it evenly to all cylinders so that makes sense. (If what I wrote makes sense)

I still think Mike has a point as well as other Meth haters do but I fully understand your point and the fact it can be done with minimal risk. Any high boost application is risky, so with power comes risk. The key is to minimize it.

It is just funny that a lot of the guys that support meth rather than having anything intelligent to say always say...I know this one guy who is running 600whp and he has been for 2 years...which equals Meth is safe no matter what.

An interesting debate for sure.

Nice post Scheides. I'm neutral on the injection stuff since I never had it, but It sucked seeing aquamist try to defend it himself in that thread on evom. It's more about the person with the kit, than the kit itself.

[goodhart]

Seems like it's so much like Nitrous, a few idiots that hack in a kit to go fast give the majority a bad name.

This is the TECH section. Next OT post can be the 2nd go to on vacation b/c of this thread. I'm tired of having to clean it up every time I read new replies.
