Hey guys I'm interested in running water/meth on my f20c boosted, and would like to know what kind of setups/brands you guys are running and would like to know how reliable its been? and What kind of power you have been able to make with it! Thanks

 

Aem meth kit has been reliable since I had it.
This is my first time using this site.
Not sure if I replied right.

 

A good note to add on this that I have learned from experience and had also been told by several tuners. For power less than 500 a single nozzle is fine to use but for cars making more than 500whp you should really go to a direct port setup. I have seen way to many high hp cars run lean on the furthest back cylinders do to poor spray or therefore lack of atomized methanol reaching the back cylinder(s). With that being said BUMP!

 

 

I will be running a aem v2 shorty and looking for 500whp, and running single nozzle, but now I'm reconsidering direct port after hearing the comment above

 

Has anyone tried aquamist? I recall talking to Jeff at evans tuning and he told me that direct port was better, I could be wrong its been a while ago that I had spoke to him about this but thats why I assumed direct port was better, something about spraying through the throttle that the meth in the long run isnt evenly distributed and that direct port was better? Are you guys running straight meth or 50/50 with water or 75/25 water?

 

Yep, in my experience if you want to make big power you will be relying on a higher percentage of injection to gasoline and therefore even distribution is key, that means a direct port set up. A single port/pre TB works well for lesser demand applications where cooling the intake charge with superior atomization is the key role, rather then really inducing a secondary fuel source. Higher percentage of water typically is paired with a single port/pre TB like 100% to 50/50 where it can more effectively atomize with the incoming air better. A higher concentration of meth per water I would recommend in a direct port set up for these reasons stated above. You do not want to hydro lock your motor from direct injecting too much water. Depending on what size nozzle you go with, I would air on 25% water and go down from there. 100% meth may work best for your needs, I have experimented with all percentages in a single port design and a custom milti port. 50/50 ratio is based on safety first rather then best function for all applications, that’s why it’s mentioned as the ratio to run in these off the shelf kits. It’s the ratio point that won’t combust under an open flame. Any higher percentage meth to water and it will.

Besides meth to water ratios, nozzle sizes and layout, there is also the controller aspect which is equally important.

**There is 3 basic designs, the typical progressive system which starts injecting a lower pressure at the set rpm and boost point you want and then ramps up the pressure to increase its cc amount to the max set point, all based on rpms and boost the controller sees. So depending on your two min/max rpm points, will dictate how steep the ramp up from low to highest pressure.

**The other is a single stage, where its just an on/off, so you tell the injection at what throttle percentage and rpm/ boost amount, you want it to inject full pressure.

**The other is a multi stage, which works the same as the single stage, but you have multi injection stages, allowing you to fine tune the injection a bit more. Typically running a smaller nozzle on the first stage for lower rpm where better atomization is needed and less demand because of the lower rpm, and then a big stage for a bigger set of nozzles and higher demand. You can effectively run a single port/pre TB on the first stage and then a mutli point injection for the second stage and get the best of both worlds.

The benefit of a single point/multi point is optimum atomization with higher demand/bigger nozzles because your injecting full pressure now with no ramp up.

The benefit of a progressive controller is you can simplify the set up and fine tune the injection to the boost curve of the engine. I find these work better with a supercharger where the boost curve ramps up with rpm like the progressive controller. For a turbo set up, depending on turbo size/boost ramp up rate, a single or muli stage system may be the best option.

Hope this overview helps. There is more to this, but just wanted to give you the basics in a nutshell so you can run it all by your tuner and see what they recommend for your set up. You should understand the fundamentals of anything before you put it on your car.

 

Not to de-rail, but has anyone tried nitro booster with a water/methanol set up?

 

No but always wanted to. Never did.
