Bob will argue where that kit should actually be fitted but I don't think he'd argue against a progressive kit.Then again he might, just for the crack of it

.no intercooler, no chargecooler, 95 octane fuel, 22psi, garrett ball bearing turbo, stock head gasket/pistons etc, temps on boost have been below freezing on a 26 degree ambient measured with AEM sensor on link G4.
Water does not cool intake temps, yea right Bob.
For more info please read.

There are plenty of people that spray water before the turbo, you cant tell me that any of the small amount of water they use remains as liquid after going through that so I cant see why the manifold would not be a suitable position for temp reading.

T.F.S. wrote:Yes Bob seems to have a lot of story's, pity he does not have any hard evidence/testing data to prove anything which is odd for someone who has spent so much time testing something as simple as a water injection system for seemingly years on end..
I have an analytical background/job, I design drug formulation coatings and conduct many tests on these compounds on a daily basis so I am no stranger to testing in an analytical fashion.

I started work when I was 16 with a race team, I have been a nitrous/WI installer for something like 15 years.
The very low inlet temp figure was with methanol and water, it's not that surprising really.

I was going to calculate the possible cooling effect of WI Thermodynamically, but the guy in the link above has done it for me.
What I can't see in his calculation is where the amount of time the water spends in suspension in the airflow before it reaches the intake is taken into account?
I think this was Bob's argument for its ineffectiveness, that there is not enough time for the heat to transfer from the air to the water.
Or am I missing something?

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.

To drop air temps over the range I'm guessing that fast it would require a lot of energy?
I'm very interested in the theory.I don't disagree with the benefits of WI but would like to know the math behind it.
