Default Re: Injecting prior to turbo comp' impellers

When dumping so much water/meth in, it could become hard to actually measure intake temps.

How much is actual charge temp and how much is simply the fluid temperature on the sensor ?

Has anyone done any testing before and after the nozzles using a few sensors ?

Maybe stick a thermocouple into the intake manifold close to the intake valve, so hopefully any state changes have already occurred by then so may give a better picture of actual charge temp ?

I did try my own car a few days back with 2 nozzles pre TB and a single 1.1mm in front of the compressor.
There was no measurable performance gain over no WI despite running slightly leaner with some 5deg more timing.
Although I suspect it's down to me fitting a new 200psi pump as well. I'm probably just drowning the engine with water/meth 40/60

need to resolve a few other issues before can try anything more.

I'd previously been using an 5 year old 150psi pump and two of the largest AEM jets. the new 200psi pump must be flowing a huge amount more !
