I'll preface this by saying I already own an aem V2 meth kit, and have been running a 640ml/min nozzle, pre throttle body. This is in a '16 f150 with a 2.7.
Purely by happenstance I ran across some research about injecting w/m pre turbo. There are a lot of naysayers claiming it can erode the blades on the turbo, but I haven't found a single claim that this has ACTUALLY been a problem for anyone. However, I have found plenty of first hand accounts that they ran pre turbo injection for years with no ill effects.
I've also spoken to Rodney at alcohol injection systems a bit about this, and he says the same thing. In their experience, and from all of his customers' reports, pre turbo injection has never harmed anything.
What it does, reportedly, is cools the air charge at the source of the heat, and by cooling the air at the turbo, causes the charge to be denser, and effectively flow a few more #/min, moving the efficiency range a bit. Allowing the turbo to act like a larger one.
It seems the magic formula is a small nozzle to produce a fine fog pre turbo, then another, larger nozzle right after the intercooler. Most of what's injected pre turbo is completely flashed off, and doesn't give the benefits that most use methanol injection for by cooling the combustion chamber and adding octane. Hence the post intercooler nozzle.
Most of what I just wrote is regurgitated information, most that I understand pretty well, but some that I don't. I'm mostly just in a researching stage right now. If I'm going to have the resource of methanol injection, I'd like to reap maximum benefits from it.
I'm curious if any of you have any real world experience with pre turbo injection , especially on this platform. Real world, what will it offer me? Seems like these little turbos are probably being pushed pretty hard at 20+ psi.
Many thanks.
