Reflective Heat Wrap Air Intake

It might help some, but you are at the point of diminishing returns. Once everything is heat soaked, even with the DSE heat shield, your IATs are going to be high when sitting or moving slowly. That’s just the nature of the beast. The DSE heat shield helps to delay the onset of those high IATs, but it is inevitable. Insulating the air box is better suited for something like sitting in the staging lanes at the drag strip.

At high rates of speed on the track, your IATs should be close to ambient with or without the heat shield and/or insulation. I’d try to log IATs just to prove it to yourself, especially before spending big $$$ and time on something you may not even need.

Thanks for the thoughts Steve, and more or less told me what I already knew. My IATs on the track now are very close to ambient. However, sitting in the staging area waiting for the previous group to come off can sometimes take 5-10 minutes and stuff gets hot.

Typically it’s cooled off by the time my tires are hot, so you’re right, probably not worth it.

That’ll do it right there…hood down, engine running will make those numbers go up in a hurry, especially when the fans start blasting. At that point, if you aren’t at a point where you can open your hood, you are best to just let it be, as shutting the car off with the hood down after it is nice and toasty will make your IATs spike big time. At least based on what I’ve seen on my own car.

As soon as I get in the staging lanes at the drag strip, I shut down and put the hood up. Kinda hard to move the car safely that way though 🙁 I usually have to wait about 20-30 minutes between passes though, so plenty of time to cool things off.

Yeah, I probably just need to drive down and grid, turn off and leave the hood popped until the 5 minute mark and then start getting ready.

Great idea. Drag racers will put ice bags on the intake manifold.

I have DSE’s intake box, and have it heat wrapped. Would I see any cooler IATs if I were to wrap the top of the intake and smooth tubes?

Thanks,
Nick
