After completing my 3800SC swap, i get a LOT of heat in the trunk. i have the factory heat shield in place, a 1/2" air gap to the exhaust and wrapped the exhaust in exhaust heat tape. Still after a run, i can't hold my hand on the front of the trunk wall. i had some clothes in the trunk and melted them. What have others done to keep the trunk wall cool? ------------------
Astronomy says we will find a coded signal from outer space. Then we'll KNOW that life exists there, for coded signals aren't by chance.
Biology says there are coded genetic signals in every cell, but we KNOW that no intelligence created life.
I'm the original owner of a white ' 84 2M4 purchased Dec 10, 1983 from Pontiac. Always garaged, no rust, 3800SC, 4-wheel drifts are fun!

I lined both the inside behind the carpet and the outside with this stuff. Makes it warm instead of hot. Granted there's a muffler pretty much directly under your trunk so it kinda comes with the territory. The mat will help a lot though

GM only had 1 or 2 heat shields for that... rest cooling there is airflow thru the engine bay.
See http://www.fiero.nl/forum/Forum2/HTML/141784.html Fiero Engine bay vs Heat.
New engine likely use more space or blocks air flow in a given area.
May have exhaust leaks heating the area.
May need extra heat shields blocking IR from exhaust lighting up whatever.
If trunk wall is getting that hot then other things are having heat problems too & things like ICM won't last long w/o proper ail flow, heat shield(s), etc.------------------
Dr. Ian Malcolm: Yeah, but your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should.
