sorry we went from radiators to a discussion of the best coolant (not entirely unrelated )

 

What's your guys take on "water wetter" from Redline?

It seems like a good improvement to the non-engineer guy. My real world experience with water wetter has been good.

 

All evidence indicates that it works and if you live in a warm climate, I don't think you need look further for a solution... The only issue would be the low boiling point. I am considering redline water wetter + distilled water + higher pressure radiator cap, but it would mean I would have to change the mix in the winter (here in NC it occasionally drops to freezing).

 

I put in redline water wetter and the data logger showed an average increase of coolant temperature of ~3 deg F when driven on the same stretch of freeway at 70 MPH in cruise control. (Same atmospheric conditions.)

Other than coolant temperature, I can't say what it did to the block or head temperature.

 

Well great, you' re just full of good news

Was that distilled water with and then without water wetter?

 

It was the stock mix of antifreez and water.

The coolant temperature increase could be argued as either good or bad. I could make a supporting or refuting case either way.

Was it more heat comming out of the engine?
Or was it a decrease in coolant heat capasity?

My guess is it only made it worse, but then again, I don't really know. I can only say with certainty it was slightly different.

 

did you have the same starting point?? i am sure that the car was hotter on the second pull after adding it, unless you let it sit overnight and went down the same stretch.

i have seen -10 degrees F with addition of water wetter on my dyno.

 

just a shot in the dark here, but I'm guessing you guys weren't exactly smooth with the ladies.

 

Jeremy, is that distilled water + water wetter or a 50/50 EG/W mix + water wetter?

 

Can I just use the coolant from the Enterprise's warp core?

 

When you use distilled water [and wetter water] you need to recalibrate [miscalibrate] the coolant temp sensor circuit by adding a small series resistance [say a 0-20 ohm variable pontentiometer] to null [adjust] out the 3-4F increase the ecu sees.

The temperature increases because the head is transfering more heat to the coolant..................to see the truth you need to install an equal sensor on the rad outlet/engine inlet and compare efficiency.

The hotter rad inlet coolant the more efficient the rad becomes due to coolant vs ambient differential temperature..........say 1% more efficient yields less than 1.0 degree outlet drop.

Without an accurate heat temperature measurement hotter vs cooler coolant is pretty meaningless.

 

Not really.
Hey we had some very hot blonds working there too.

Players, Casanovas, Punk Rockers with purple/green hair, sex novel book writers, musicians, deviants, A-holes, mental cases, conservatives, liberals, freaks and night club owners. Everybody...
They were all into the science and engineering like everybody else.

 

Same starting point and driven for about 1/2 hour both times so it was well into thermal equilibrium.

 

How can you be sure of this?
I can just as easily argue the increase is due to a decrease in heat capasity.

 

Because you measure the head temperature to confirm what's happenning. If the head temperature drops and the coolant temperature increases you have your PROOF! If the head temperature goes up then I am wrong......SIMPLE!*
* I you test Evans coolant or even 100% ethleyne glychol you will see an increase in head temperature and frying oil.
Best done on a steady engine dyno where all the hundreds of parameters can be data logged to an accuracy of 0.1F

 

That 2nd sentence was a little difficult to interpret. I take it you mean that with Evans the head temperature will rise to the point where oil will actually start to break down? As in excess of 250 F? 300 F? Vaporization not till 400 or so, yes?

 

Of course, but your prior post planely states that it works by transfering more heat to the coolant. Have you, or anyone you know, independantly pre/post tested head temperature on a VQ with any of these modifiers?

Its all marketing and speculation without test data on the VQ.

Sure, but a VQ laboratory engine dyno is never going to happen in our world.
The best that is going to happen is a Innovate Motorsports data logger on a road test.

BTW, are you saying that using Evans or pure glycol is an inferior coolant to water? And that Water Wetter with water is the best coolant overall?

 

DAMN !!!!!!!!! This is some high tech sh@#T going on in here. I dont even understand about half the crap you guys are talking about. I need to get my edumacation on.

 

I'm not promoting wetter water just distilled/demineralized water with some type of anticorrosion additive in the smallest suitable concentration if lowest aluminum head temperature is the desired end point.

Measuring coolant temp sensor with a scanner is useless as far as head temperature is concerned.

One factor to consider is the upper limit of the sensor and it's reaction to low water level or steam.

 

Right on. Now that's the kind of well considered answer I've come to expect from Q45.

EDIT: BTW I mentioned Innovate Motorsports above to imply that head temperature would be measured via K-type thermocouple.
