Bad Penny runs the standing mile and other Sandhills frivolity..

I wonder if another 5mph would cause the window to break?

Would they allow the windows to be open? I wonder what the aero effects would do vs. the rear glass staying put.

Wicked burnout.

Props to the navigator too

The aero with the windows down would be crap.. heck, I was driving a '67 with the windows down once and it popped the headliner (was older) at 120ish mph.

the window breaking would look pretty good on film though

So who's going to be first to market with these for a 1st gen?

Tempered glass (7/32") holds up incredibly. Back glass popping out would be relative to the bonding to the body, modern cars are bonded in with autoglass polyurethane, 220 psi when properly bonded. Butyl tape like 8 to 12 psi (goes lower when its hotter, liquifies)

Interesting bout the air pressure; you are displacing so much air, so it creates more pressure inside the cab, i would think it creates a vacuum. Its an airline equation right?

Bout the hp chart, with the 3:50 and sixth gear, 243 with 685 rwhp, its only in theory, the Veyron, aero'd, 1100 horsyish, does 250. I read somewhere once where it takes an additional 100 hp +/- to increase 10 mph or so above 200, think about how much the air compresses and how it exponentially corrects itself. SIMPLY AWESOME!!!!!

Did i spy the Finchmobile on the side in the run down?

Correct. The air passing by the car creates a low pressure point. The pressures inside the interior of the car are pushing the windows out. I don't think there is an actual vacuum involved though. Just greater pressure on the inside compared to outside

Thanks..

Next goal would be 180...

Steve, a couple years ago I swear there was an aerodynamics sticky on pt.com in advanced tech I believe. I read everything that was linked and found it very straight forward and easy to understand. It even talked about string testing and using two different gauges to monitor pressure differentials across say the radiator to help cooling capacity. Given that the car has no aero mods, you may want to look into adding some. I'm sure a belly pan of sorts would help and not change the way the car looks. It may even help with air flow through the radiator. The author of the links I read used a belly pan to lower his intercooler temps. It was just a matter of monitoring pressure differentials to ensure air was flowing through the engine bay.
