If you use it for cooling only, how would it not make more hp since cooler air = more oxygen density so you can add more fuel = more hp?Cooling the charge air once it's been compressed doesn't automatically make more horsepower. But if IAT is an issue, you can run more timing with methanol safely, which will make more power. Mix it 25% meth, 75% distilled water.
Using it as an octane booster works if you direct port inject, and use 100% methanol. I wouldn't try a fogger nozzle in the charge pipe. Distribution issues in the manifold can cause uneven distribution.
So now I’m really confused. This is my first forces induction vehicle, I’m under the impression that the charge pipe is the pipe connected to the throttle body. All the reference I’m seeing for centri units instruct to put the water/meth nozzle in this pipe. Even the manufactures of the various meth kits say to put the nozzle into this pipe. What gives? Or am on not understanding something correctly. I just want my 91 octane gas to act like 93-94 octane to make my knock sensors happy. I am hoping water/meth injection can do that even though I don’t have a high IAT problem.... I wouldn't try a fogger nozzle in the charge pipe. Distribution issues in the manifold can cause uneven distribution.
Cooling compressed air only changes the density of the molecules inside the manifold/pipe, not the available oxygen content. This density change will increase (when hotter) or decrease (when colder) the pressure in the manifold. You're still working with the same number of oxygen molecules (and power potential based on that oxygen).If you use it for cooling only, how would it not make more hp since cooler air = more oxygen density so you can add more fuel = more hp?
There's nothing wrong with running it in the charge pipe.. you just don't want to do that with anything more than 50% methanol/ethanol. If it's combustible, you want it direct port, as it's being used for fueling. The plastic factory intake manifold is not designed to distribute droplets of atomized liquid, which will lead to uneven distribution and some cylinders running more/less away from ideal A/F ratio. So, for cooling, keep it under 50% meth/alky and you're fine. It won't combust.So now I’m really confused.
