Removing hood seal- Good idea/Bad idea?
I've heard people talking about the "old hotrodder's trick" of removing the seal or gasket from the back side of the hood.
Does this cause any problems?
Has anyone done it?
The last thing I need is a short in my ignition system.
Also, anyone with a cowl induction hood, do yours have those
or is water able to leak down inside by design?

I've had no problem with my rear hood seal off. Been raining all week and had no problems with water in the bay. Just don't open your hood or park your with the car facing downhill in the rain.

i took mine off a few weeks ago because spring is finally here in CA and its probably not going to rain much in the next 5 months. I havent had any experience with it yet in the rain but im sure there would not be a problem.

I put on a fiberglass hood that has no place for a seal, and I've been doing fine. Before I had this hood I had the steel one and I took it off that one too, again no leaks, no water, no problems at all.

James Montigny, I'm headed out to KCIR Wednesday night if you're interested in going as well. It will be my first real run w/ my new engine. Last time my alternater went out while staging

Hey R90, I havn't been to KCIR in about 2 years.
The baby is due any day now, going to the track is
definitly not on my list of possible weekend activities.
Maybe we can meet up later this summer.

It adds a cowl effect, granted not that of a cowl hood. But a small amount of cool air gets through

Re: Removing hood seal- Good idea/Bad idea?
The seal serves three purposes.
It prevents rain from entering through the cowl.
It prevents engine smells from entering the fresh air intake for the cabin (the fresh air intake is on the windshield side of the gasket).
It helps establish a low pressure area within the engine compartment which improves airflow through the radiator.

What makes a cowl-induction hood work? The fact that the cowl is in a high-pressure area. That's why the HVAC system pulls air from the base of the windshield on most vehicles, too.
So what happens when you allow this high-pressure air into the engine compartment? LESS AIR FLOWS THROUGH THE RADIATOR.
Factory cowl-induction systems ALWAYS seal the high-pressure air to the carb inlet using a different set of seals. Some are rubber, some are foam...but it's always sealed so that the cooling system isn't compromised.
A person has to be nuts to remove the seal at the back of the hood.

I left mine on because of Cowl induction.

Re: Removing hood seal- Good idea/Bad idea?
What I did when I had a cowl hood on my car was take the seal and use some 3-M rubber cement and glue it to the cowl itself, just follow lines of the cowl, worked perfect. No smells from engine compartment or water getting into areas I didn't want.
