So how can you be sure your reading o f the inlet temps is correct? Do you see my opinion with regards to the moisture collecting on the probe.
I'm no expert when it comes to car engines and injection systems but I am an expert in testing and measurements.
I don't have any evidence that it is 100% correct but I seem to be the only person in the discussion bringing any evidence at all, what we do know is that methanol engines run very cold in general and the freezing temps I recorded were when injecting around 2L per min of methanol (still with 250cc of H20 mixed in) which does not really surprise me.
I cant see what water would remain as liquid after passing through the turbo (pre compressor inj) so this argument would seem irrelevant in that scenario, phase change happens before the liquid even reaches the turbo, even if it wasn't there would be explosive vaporisation at the tips of the compressor, temperature of the inlet is reduced due to latent heat of vaporization.
So you're adding the water before the turbo. But the Water only cools when changing from a liquid to a gas. If there's no water vapour left after the turbo, how is it cooling the compressed air after the turbo.
You also say your injecting at 2l per min. When you go for a drive for half an hour, how much methanol/water are you having to carry. Surely you can't have a 60l tank onboard
If what you're saying is true, I can't understand why the likes of Audi, Merc, and even Bugatti haven't used wi to reduce the weight and complexity of there intercooler systems.
Do any super / hyper cars use them?
I just can't see liquid cooling the airflow at such a rapid rate in such a short distance to offer any beneficial inter cooling effect to the air charge temperature.
In the 15 years you've been installing surely you know some real boffin who could explain the ins and outs.
