    have any one used a grabber hood and set it up a like ram air //// and on a hood with a regular scoop what do you do about driving in the rain with the water getting the filter wet ///// what do you think about running a cold air setup like a newer mustang but still with a carb

    I opened up the 66 GTO hood scoop on my Falcon and the rain doesn't bother it. I have an open K&N filter so I guess it pulling air on the back side of the filter. I'm not going to be stomping it to the floor on a wet road so it is pulling enough air to run fine. The heat under the hood dries it out kinda fast. The Grabber scoops ain't big enough to pull enough CFM. Look at the size of the Thunderbolt ducts...they're 6" each or better.

    If you put the intake duct lower than the carb...You will have less chance of pulling in water.It wont travel up hill too well at normal road speeds.Be sure to put some type of drain in the ducting to expell water that collects in the low points.

    the first problem is that the grabber ducts pretty much are on top of the shocks. it has been done but as stated before they are on the small side for air flow. the cool air that they would add under the hood should help. ive dreamed of doing that with two more ducts coming from each side of the radiator core support. as for water. you put small hole in the ducts at the lowest point so water doesnt pool in the ducting.

    Since hot air rises...it does let the hot air escape out from under the hood at red lights and stop signs. I'm looking through distortion from the heat when I stop.

    My white Comet had a 70 Mach 1-style scoop on it to start out, as shown in the pic below. Florida rains get pretty extreme and it did leave me stranded with a wet ignition 3 times in that first summer. This was the early 80s, and snorkel scoops were just getting popular ... put a 5 incher on there and it lived up to it's name. Never had a problem after the swap.

    My current one has a mid-80s Mustang GT scoop on it, and the hood is opened up, letting the air filter protrude in there. (351s are pretty tall ... :D). I got some U-shaped sheetmetal, and made a 1/2" lip around the opening. The top of the "U" faces out. This was also caulked. Any water that runs across the hood surface into the scoop gets deflected and will not get the motor wet.

    This car was my daily driver for 7 years. I have driven this in the heaviest rains multiple times and never had a problem.

    My Dodge Demon scoop is raised off the hood surface and I never had any trouble with it sucking water. In the heaviest downpours, the filter may have gotten damp right in the front portion. Never to the point of clogging or hydrolock.

    Same with my Chevy Z28 taking in air low. It wasn't the type with a duct, so it never sucked water. Air was forced up by the air dam and it made a huge difference in power on the highway.

    The one time I had issues, it was more with water in the ignition like Cap'n had trouble with. It was a 71 Torino with the GT hood scoop. It was flat on the hood, and sealed with a plate from the factory. I took the plate out and made it functional. Almost right away it rained and flooded my ignition. I covered the distributor, then noticed a wet air filter several times, but it never caused issue.

    A raised inlet scoop would be best for water, and probably air flow as well. On the surface, the air is pushed up a bit, so surface scoops don't get forced air flow.

    Anyway, any snorkel type, shaker, or ramped up (like the old "pro-stock") scoop would probably be best. Cowl scoops are good if set up properly, but best for heat extraction.

    Just some thoughts and opinions... others may vary!

    My scoop is open and sealed around the breather. It does get wet in few times its seen rain but filters are cheap and its not enough water to hurt anything. If I had a Grabber hood I would drill out the scoops to let hot air out. Install the batt. in trunk then route the cold air from the breather to the rad support in place of the battery. I did the Grabber hood ducting on my first Mav but it turns out too small because of clearance.

    Because of the way a Maverick's hood rises from the front edge to the top not much air gets into a scoop that's down near the surface of the hood, the air goes right over the scoop unless it's a tall one.

    i like the look of the scoops on our cars i am using a K&N filter ///// has anyone made a flap that you put at the opening of the scoop that can open and close with a pull ???
