I know the current craze fer the new models is to go with an active, computer motor controlled shutter system. Don't ask me how much it would cost to build yer own but I would figure it would be a bunch of money.

I know that someone here did a flap type of grill block that was bungee cord based and flipped up at a certain speed.

My thread over at ToyotaNation fer my grill blocks...

My grill blocks over the past few years... - Toyota Nation Forum : Toyota Car and Truck Forums

Had another crazy (different) idea fer grill blocks fer my T-100. Seeing that I have the PE200 PVC pipe on the top section and smaller ones fer the middle section...engineer them so they stick out away from the grill when the truck is at a stop or slow speed. As the air pressure pushes on the grill blocks when you are traveling at a higher speed, the grill blocks retract into the grill effectively blocking the grill. Maybe an option to lock out the grill block from activating fer heavy tow loads or locking it in place during the cold weather season.

Things I need to figure out...
How far out front the blocks would have to be from the grill to keep the cooling effective at rest/slow speed?
What the compression resistance would need to be to keep the grill block from closing too easily?

Kinda got my inspiration from the Ford F-250 Super Chief truck...and the Spare Bumper.
