I agree colodude is doing a great job and the results will be interesting to witness. I didn't mean to get people distracted asking if anyone had measurable results from alternative heat extraction methods. Real data/results are much more valuable than generalizations from internet know it alls.

Related. Sorta.


Also friend has a '76 Camaro that had a stock hood with a hole someone cut for a filter. He swapped it out for a 2 inch cowl and did achieve lower water temps. Especially at low speeds/ cruising. At idle you can see all the extra heat leaving through the cowl. But like others have said. It's for induction of air not exhaust.

No... I'm saying your using language 2 degrees above your education level... They're hood vents for God's sake. You debate the simplest **** yet constantly say it doesn't matter, I don't care, I don't know, who cares....

According to JD... It takes a person with 3 engineering degrees to install hood vents.

Empirical data can be collected by anyone. My request actually had no requirements for education level. I don't know where you got that idea. I was just asking if anyone had proof whether it worked or not. You are the one always talking about how degrees make you special, not me. In fact my comments insinuated that 100 degrees don't necessarily make you right about everything, that I prefer actual physical evidence/experimentation to the opinion of an educated idiot.

Here is a video showing empirical evidence of air extraction via hood louvers on a BRZ.
Would be cool to see similar experiments on Cobalt. Based on everything I have seen so far it seems air would flow into the engine bay instead of out if the cowl is removed or if the hood hinges were spaced up. I still think it would make a worthwhile experiment.

If you did you interpreted the data incorrectly.

Can you two **** already and get over it?

Take your old married couple bickering to PMs, this degraded from relevant to irrelevant personal attacks.

You can't PM JD... he will post your PM's... Been there , tried that.

I don't know why there is still a debate.... You tried to set them straight.

Adrian needs a big ass hood scoop like my Subaru has. Plenty of airflow fam. **** empirical data, **** louvers or whatever communist bullshit named those things. Freedom Vents is what he should call them. louvers is like french or some ****.

All I meant by empirical was actual/real/measured/physical and not theoretical only. I didn't know it was a controversial term that required a doctorate to use and I sure as hell didn't mean for it to cause as much excitement as it did.

I dont think you did sir. I think you knew EXACTLY what you were doing. Dont try to play dumb. I have a doctorate from University of Phoenix and another doctorate from MIT. ok

I'm guessing something like these... Although they are about as rare as they get these days.


#10225885 - Left Side Louver - $40.99
#10230097 - Left Side Drip Pan - $8.06

#10225886 - Right Side Louver - $40.99

Wasn't it Jesse that wanted to carbon fiber everything to make it lighter? I don't remember the thread.

He should help colodude make something special

Jesse hasnt made any carbon parts in a while. He was putting a carbon roof on his car last I asked.
