Underhood Liner: How many of you still have it?
I then cut that black rubber seal, the seal that attaches to the car but touches the hood when the hood is closed (I hope I am making sense). I only cut the middle part section / the curvy party above the TB area. I am keeping it, in case I want to put it back.
Anyway, I was at a red light and with the background of the red brake light on the car in front of me I could see more of the engine heat - heat wave - coming out from the hood vent and area above the TB.
I have this flat, long flashlight that I put on top of the TB, closed the hood and then turned off my garage light. In the dark, I could clearly see the light through the hood vent and from under the hood through the area I cut away above the TB.
I then taped some toilet paper in certian spots above the vent and underneath the hood on the outside, in front of the windshield, where I cut the black rubber seal above the TB. I then took my shop vac and reversed it (so it would blow air) and you could see the toilet paper moving -showing the air flow or how the heat wave could be allowed to escape the engine area through the hood vent and the area above the TB.
This was not very scientific, but I know the engine area is definitly allowing the engine heat to escape. I am going to now jet hot coat my surge tanks and valve covers, in hopes of further reducing engine heat. Also, do I know if any of this will increase performance? No, I do not, but does it make me happy and keep me busy with my mod hobby - yes.
