Since the new hoods are effective for engine bay cooling, was thinking how to get a little more cooling on my '11 ss ; so I took off the rear hood seal, just pull's right off, now I have a 3/8" space between hood & cowl, has anybody tried this for better cooling ? Can't see why this wouldn't work a little, cool in from front & heat out the rear!

That will work to get heat out, however when it rains, now lots and lots of water is going to go into your engine bay and get lots of things wet.

No, there is an almost a 1" high ridge that the rubber seal sat on, all the way over to each fender where the water would have to run to, then down on the inner fender & to the ground. Thanks for the heads up, I didn't think of that about the water till I checked it out.

It also dumps the hot air straight into the suction for the cabin vent and a/c.

It wouldn't be any different than a larger cowl, would it?

At speed, the base of the windshield is a high-pressure zone, hence the effectiveness of cowl-induction.

I'm not sure how much flow-through venting you're going to get under those conditions. At lower speeds, probably yes. At higher speeds, I think that "outflow" turns into an "inflow." How that will affect the cooling, I don't know.

If it was that simple and effective of a fix (and could save GM money by not putting the seals in place on every car), don't you think they would have done it?

They may have been influenced to keep it as its added "insurance" to keep water out of the engine bay and not worry about water damage in any fashion.
