How hot is the engine bay?
Do any of you know how hot an engine bay can get? Particularly around the intake? What temperature? I put some dynamat (rated at 350F, 175C) on the pop charger's heat shield to improve its purpose. It works by the way. But i'm afraid the dynamat might not be rated high enough to withstand the engine bay temps. Can anyone advise? I live in Texas where it's HOT!
Thanks,
Thanks,

Kind of on the topic of heat, and kinda not directly on this topic. Bu I will ask anyway, has anyone ever louvered there hood. It was real big way back in the day with hot rods and was just wondering is anyone has ever seen a z with hood louvers.

Radio Shack has inexpensive outside [15-20'] wired digital temp gauges, great to mount sensor underhood or in air path to see the horrible performance of most cone filters even with INSULATION...........especially compared to oem system.
All that counts is inside plenum temperature.
The MAF assembly has an IAT sensor that can be read from OBD2 scanner/data monitor.
For every 11F temp rise the density and power output drops by 1%.
Consider in summer that the rad raises temp by 20-30F and AC condenser by the same amount........not unusal to see 160F air flowing into a cone.

Your car gets the hottest when it's idling.
When you're driving around, the engine bay is only slightly hotter than ambient temperature.
Get a meat thermometer ($5, grocery store) and zip-tie it somewhere inside your engine bay. Then let it idle for like 10 minutes, and check the temp.

My engine gets so hot that i have to open the hood after i drive it. And when i come back into the garage after 1/2 hr. it's like an oven. (could possibly be the blower) but i know it gets HOT.

I think it is being used to close off the gaps in the back. That makes sense anyway.
