As we all know.. Colder air is denser air.. More air, more fuel. But also, more power..


When you start looking for power, MPG concerns shouldnt be reflected on.

Agreed. Thats why I only use premium fuel, also. Even before the tune.

I let the car cool down when I first get to the track, after that I can run until the cows come home. With consistent times, too. Coolant, trans, and intake temps stay down as long as I'm running. After 4 runs in a row, however, brake fade starts to set in. If I find myself stick in a line to run, the fan switch does come in handy. The trans and engine temps go way down, but if I run it too long, the intake temps go up since the CAI runs right behind the cooling fans. I dropped .2 secs in the 1/4 mile when I switched from the short ram to the cold air intake.
Not sure why I didn't do this before but I am absolutely convinced that I will be doing the sunshade mod. I will be ordering the material needed once I get home from work tonight.

I plan on doing some bracket racing once 'The Queen B' gets out of the shop. Creeping around in the staging lanes have a tendency to raise the intake temperature more than I care for. Thanks guys for suggesting and testing this out.

Ok guys, where can I buy this 'Sun Shade' from? Been looking around 'Googling' and coming up with a bunch of random stuff. I am very interested in it and want to try it out. Thanks!

Pretty sure most are using the following:

I used the following, it was worth not having to cut the sun shade into strips.

Be sure to use gloves as this is heat reflective fiberglass ...

Keep in mind, no matter what, the iat sensor is in the maf in the engine bay, and the engine bay is like a pressure cooker. Even with my layers on top of layers, the only way the temps stay down is by keeping air moving through the intake. Don't get me wrong though, the wrap is definitely worth doing, especially for the price. For 30ish bucks and a little effort, you're buying your self some valuable time in the staging lanes. But there is a reason why most people take the inverse approach to solving this problem. Header wrap, hood vents, etc to keep heat out of the engine bay in the first place. I think I will try that next and I will let you guys know if it helps or not.

https://scontent.ford1-1.fna.fbcdn.n...ce&oe=5A0F37EE

...and had a but left over so wrapped as many heat sources near the intake as possible... Trans fluid lines...

One thing the honda guys do is use washers on the hood to tilt the hood so air moves out of the bay over the windshield.

idk how thatll look on a Avy or Camry tho..

Oh, it looks bad. On every car... 😁


Vents would probably work best, but then there's rain and snow. How's no one ever tackled that before? Closest thing i could find online is for the frs. They have trays that can go underneath to redirect the water.

If your just doing this for the track, just take off the hood (if track laws allow)
