    Aluminum plate vs mild steel plate in this application

    The steel plate has a slight taper lengthwise but those dimensions are close. There are no ridges in it, it's a flat steel plate.

    Explain venturi tunnel design (downforce) on race cars

    I've tried to find info, but nothing that gives a crystal clear idea of their design. I know that they speed up the air to result in less pressure/downforce, but I'm not sure whether they narrow vertically, or if they all have an upside down wing-thing going on the inside roof of the tunnel...

    Aluminum plate vs mild steel plate in this application

    Some notes: The OEM 1/8" thick plate weighs 6 lbs, the aftermarket 1/4" Al plate is claimed to weigh 13 lbs. The lettering is painted, not machined into the aftermarket plate. When the vendor described the plate as 'CNC' I assumed the lettering had been carved into the Al plate. Now I...

    Aluminum plate vs mild steel plate in this application

    Well, I'll be dipped. With 1/3 the elasticity of steel, just doubling the thickness makes it that much stronger... So basically, for simple comparison sake, it's 2.5x stronger, or 4 x stronger? Even so, I think the lettering carved into it and two sided (instead of four sided) mounting...

Disturbing that enough to keep the airflow attached rather than having it curl off and create lift. Same as properly placed riblets, dimple...

    Aluminum plate vs mild steel plate in this application

    The 1/16" reference was saying if aluminum needs 1.5x the thickness of steel to have equal strength...which means 3/16" aluminum just to = the strength 1/8" mild steel piece. Then the 1/4" aluminum piece is only 1/16" thicker than that(!). So how much of a change/gain has been accomplished...

    Aluminum plate vs mild steel plate in this application

    A Viper performance shop is claiming that by going from 1/8" mild steel, to 1/4" aluminum for the 15"w x 30"long underbody plate that comes on most if not all 1992-2002 Vipers that "Our pan will increase the stiffness and rigidity of your frame " and "The big picture for us is frame flex...
