Who wants a heat shield?

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.

Heatshield
Hi i was wondering if you still make the heatshields?
heatshield
For those of you who dont know, I've been making heatshields since there are no companies who sell them anymore.
I know a few of you were asking me about them before I got a chance to make anymore but starting next week I'll be making them again
I've already got a couple people lined up for them so if anyones interested let me know! They're $70 and if you have any other questions feel free to ask.
