I put meth in my fuel tank but only to sneak it across the border

 

^lol

 

the only thing with meth is to use it as a safety blanket to push it a little and not where your tune is so aggressive because you have meth.

 

Yeah I would not advise using meth and tuning it out to the max unless you have a good failsafe. Just use it for its other features and enjoy the extra 20-30 hp it gives you from that.

 

Yeah I'm looking for around 50 more but if its going to harm my engine than it's not worth it I guess

 

its not going to harm it by any means. its just when you take advantage of what it is, and then it fails, you can seriously harm something. Just use the cooler IATs and EGTs for more psi for power. that way your tune will always be safe.

 

Thats correct. Nothing wrong with tuning for more power while using meth. AEM and Snow Performance have failsafe systems that can retard timing or cut boost if the meth pressure drops too low (pump failure). They work well and should always be used.

Direct injection is the way to go, but the next best alternative is place the nozzle before the turbo. The next place I would locate the nozzle is just after the compressor outlet. The more time the mix has to atomize, the better.

 

So would just spraying water be safer and pick up some HP?

 

That’s exactly right, particularly if utilizing a single port. Single ports are nice because they are located pre TB, giving more atomization time, this is the most beneficial configuration to lower IAT an produce a all around denser charge which in itself produces more power, however to be careful not to tune any more aggressive then you would without it, as distribution between all cylinders wont be reliable. Multi port with a good failsafe would be what you want if you are wanting to get the most power out of the motor through aggressive timing, the distribution is even between all cylinders, and with a failsafe such as map switching, boost or ignition dump it’s hard to go wrong. I have both systems but choose to run the single port these days because overall I think its more effective for DD and I don’t have any failsafe in place.

 

No, 50/50 is the most efficient that is safe ( wont combust under flame). Just water can be run yes, but you really have to make sure your nozzle isnt too big and your system and nozzle placement is right for the best atomization or you could hydro lock or simply bog down the motor. Having 50% meth allows much the same benefits as pure water, but with the added efficiency of being able to have that charge combust along with the normal engine combustion. There really is no reason to run just water in most set ups.
