Default HEAT OUT OF THE ENGINE BAY?

This one seems fairly obvious, but since there has been no mention of it, here goes! How many people have taken the sound deadening matting off, from under the hood? This stuff is about an inch thick and helps to retain a whole lot of heat under the hood, with the low cleaarance of the SC, it has to make a differance. The area of sheet metal that is used to make a hood for one of these is surely going to dissipate the heat, especially when moving! I found the NGK plugs (Rock Auto) and yes the plugs and MSD wires do make a difference, now if the back ordered coils show up from JEG'*. A tip from drag racing days on plugs-filing the ground strab back till the edge is even with the center of the electrode does help!

Careful when removing the hood insulation as it'* there to keep the heat from ruining your paint on the hood!

it'* also there to act as a sound deadener. Your car will be noticably louder at idle.

I keep mine on. I'll take it off once I open up my scoops and hood. But I like the SSE logo on the insulation.

*Does anyone else have this SSE logo on their insulation under the hood?? I've seen some without it. Just curious.

how about just using dryer ducting to run air up from below the engine??? Just have the duct pointed at a relativly large open area. Another thought would be to use the insulated tape on your exaust manifolds and pipes. I think somebody has done this before...

Those exhaust manifolds are the biggest contributor to engine bay heat, besides the radiator.
The temp of the manifolds is 600 deg F.
Ceramic coating is the way to go.
Insulating wrap will also help.
You definitely want to protect that intake charge from that radiant heat.

If you're really concerned, just remove your hood for the hot summer months.
Then you can show off all those underhood goodies.

Just a thought, wouldn't a ram air hood help cool down the engine?

i've been thinking about ceramic coatings and exaust wrap for a while, and i can't figure this out ----> dosen't that just trap heat in and make air flow slower? Or does the decrease in engine bay temp make up for that and then some performance wise? what'* the deal?

My understanding is that warmer air is not that dense, I don't know about slow air flow. But don't the L36'* come with heat shields over the manifold?

Our 95 SSE had the heat sheilds over the exhaust manifolds with the tape stuff on it too.
