Wrapping stock intake with tinfoil bubble and then heat resistant wrap?

Yes I’ll report back if I see it reach 195 from those particular stop light heat soak occurrences but the only reason I kept note of it on the highway was to see if there was any cons to it at higher speeds and RPMs when everything is staying warm the whole duration of the highway trip which I did not see any . For now it definitely does seem to cool down faster in conjunction with the cabin exhaust method than just no wrap and cabin exhaust. I would have to get a stop watch to see the time difference in how long it takes for a single drop in temp and hope the weather conditions are the same, although why so many days apart, could I not just do it two different trips in the same afternoon?

 

I have 4 new brake rotors, 4 new brake pad sets and a pressure system brake flush put on and done on the car, I think the new front brakes can handle the weight until its new buddies in the back start working again.

 

I can tell you already just from one day without the cabin exhaust variable that it does help the car stay below 190 degrees before getting to a stop light and the weather was 82 degrees and slightly humid. It got as low at 186 before getting to a stop light but it stays at 186-188 at the stop light due heat soak. As expected it did what I wanted, not directly combating heat soak but to reduce normal heat soak temps before getting to a heat soak idle. Now with the cabin exhaust measure that does directly combat heat soak since air is moving from the engine bay to the cabin during heat soak idles. So all in all I would average it to 3 degrees cooler than with no wrap, which is enough gain (even as small as it is) to justify the time spent doing it, still have half a roll left of it but cost me 35 dollars for a 2 inch by 15 foot roll of it. And just a reminder this was just the intake wrap, there’s more things that can be wrapped and done to further create the effect I’m looking for. Like the manual radiator fan switch and hood vents, more costly though so hard to gauge if it’s worth it but seeing as I’ll spend 35 dollars for a 3 degree lowered temp pre-heat soak effect I guess one could see me going on to do any other things with said effects I’m looking to get.

 

To add on to my last reply here are some more notes or data taken without the cabin exhaust.

Coolant temp cools down faster when going fast (+50mph, the wrap is catching cold air from the wind coming in at those speeds) to a dead stop.

Coolant temps drop faster from high demand accelerations (Goes from 193 to 191 within seconds of lowered throttle from high throttle driving demands like over passing on highway)

Coolant temps didn’t rise as fast on uphill climbs, there’s a quarter mile steep hill I go on almost everyday and would see it reach as high as 197-200 degrees once reaching the top of the hill doing +3500 RPM @ 45-50 MPH the whole climb up the hill before the wrap, with the wrap it only reached 195 at the top of the hill and instantly dropped to 193 once I got to the top of the hill when letting up on the throttle demand, then would take 15-30 seconds to go back down to 188 degrees after that once on less hilly semi-flat roads we’re driven on.

As stated before, coolant temps would stay as low as 186 degrees during normal driving in between lights (non-highway driving).

Stayed at 188 when cruising at a steady speed on the highway below 70 MPH.

At 70 MPH it would stay at 191 for less than a minute once reaching that speed than drop to 190 once cruising at that speed after a minute or two and then 188 after 3 minutes if highway is flat. (I’m guessing more speed equals more colder air beating on the wrap causing slightly cooler material to be caught by the air going inside the intake if that makes sense, might not be using the correct words)

Can’t remember any other observations or notes but will post if I do.
