I WANT ONE!!! Please PM me with details!!

 

anyone?? lol

 

Old thread. Will never understand the point of heat shields anyways. Just something shiny to put under your hood.

 

Not that old.The maker said in May that he was going to make them again...

 

PM him then.

 

Gonna disagree with you here.
For starters, my "Blinktek" heat shield actually isn't very shiny.
It keeps the air filter/intake cooler than without the heatshield, whether using a stock airbox or cone filter on MAF.

 

Do you have any data to support this claim? What advantages/benefits does this give you?

To me it seems like the old "throw on a cone filter and gain 10+ HP" deal. Add a heat shield and your turbo will go "faster"

 

Nope. It would be difficult to do this objectively and I definitely don't have time.

But I have noticed a difference in surface temperature of either air box exterior or cone filter exterior with/without a heat shield. The proximity of the turbo to air box / cone filter means they are susceptible to lots of heat. Putting a heat shield between them sort of makes separate compartments and alters (reduces) the impact of the turbo's heat onto the pre-turbo intake tract.

 

I just think that if basic tests were done there would be no difference in the cars performance. Maybe it protects components making them last longer but that would be nearly impossible to test.

I'm sure there's a YouTube video or something out there. I've seen the one for the POD filters where you can actually lose a HP or 2.

 

My dilemma here is that you can't really do a "basic test". That means you need identical runs and also need these identical temperatures (IMO):
1) underhood temps
2) turbo/exhaust manifold temps
3) ambient temps
4) intercooler base temps (prior to pulls)

You could simulate this test, and if I were to do it I would do something like this:
1) Around 1-2pm, drive for a while and get the car up to operating temp (20+mins), without the heatshield.
2) Open hood for 5 mins.
3) Close hood. Drive for ~5mins to acclimate engine bay temps. Then do a pull through multiple gears while logging IAT, coolant temp, and timing pull (at least).
4) Stop car, and open hood for 5 mins. Install heat shield during this time.
5) Repeat 3) exactly the same.
6) Compare results, and hope they're not skewed by any changes in the ambient environment and that the air filter / air box were not already overheated from the pulls without the heat shield.

Then repeat the test so you have data comparing air box and cone filter.

Even with these results, there is still the factor of how the ambient environment affects the heat shield's effectiveness during cooler/warmer weather.

But back to the original point: you said you saw no point to heat shields; I said it keeps the pre-turbo intake tract cooler (at least on the surface); I never said it is there to necessarily improve performance.
That said a cone filter setup without a heatshield is likely to provide worse performance than a cone filter setup with a heatshield. At least in either case for the air box, the intake air comes from outside the engine bay.
