Lower Panel Modification

[GRRRR8]

This panel is located underneath the air intake system. By modifying this panel it drastically increases the amount of air to your air intake kits. Appox. time to perform mod. 1.0 hrs Necessary tools: Utility knife or drill holes and use hacksaw blade with handle.

I would suggest you cut from the top of the panel, inside the engine bay if you are able. This way you can tell where you are cutting and the exact size you need.

Instead of cutting out the lower panel completely, you can cut 3 or 4 lines into the panel forming an "H" like shape. You can then fold the front piece back and out of the way, and use the back plastic lip for a little scoop action. Granted your opening will not be a large as the original GRRRR8 LPM, but this will allow you to fold the plastic back for winter weather conditions. You can also place a piece of plastic/rubber over the LPM (from inside the engine bay) to cover the opening for bad weather conditions.








and here's a pic from inside the engine bay from above looking at the panel you cut (from top)

the factory snorkel sits right above this panel. as you can see I cut from the bottom

see DIY for the factory snorkel mod.

That works too!

This is something I plan to do when I get mine. My plan is to make it so I can drop something down there so not to suck up snow in the winter.

I would also like to look into using some aluminum sheet on a brake and bend something into a scoop and mount it under there. We'll see what can be done.

Bet you could build an electrical mechanism that could be controlled from the drivers seat that could be used to deploy a door in the panel downward like a mini scoop. It could be retractable in wet weather the keep water from getting drawn into the intake. If the door was hinged along its back edge closest to the tire, an electric solenoid or similar could be used to open it downward at maybe a 20 degree angle to act as an air scoop.

Hey Allen&#33; I am thinking of doing a vacuum operated actuator. As it goes wide open, a door opens and at slow speeds it shuts. Water is not an issue. Its too far from the inlet. Some are worried about snow packing up in there in bad weather.

You could use the motor and actuator from an old vacuum headlight system I bet. Its an interesting concept.

Looking at the ones from a Cowl-Induction hood.

That vacuum actuator concept is a good idea, and you could use a small solenoid valve(egr solenoid?) in the vacuum line to control exposure to manifold vacuum. you could spring load the hinge to close the door automatically when vacuum is cut off. Don&#39;t think snow will be too big a problem as long as you don&#39;t go plowing through snow banks, but vacuum hoses and actuator may need to be protected from icing in cold weather. Spring to close flap will need to be fairly strong as ram air will tend to force the flap open. The points of attachment for the hinge will need beefing up too. What about sheet aluminum for the door/flap? Think someone else may have mentioned that.

For those that dont Allen I have known him for 12 years. Very smart&#33; He sees things much like I do. I had him come to Ga while I was there and now I am back in Tx. Wish he was here. I could come up with an idea and he would be the one to fab it up. Get your ass home Allen&#33;
