That was a function of your granny driving style, not the intake design. It's not hard to keep cool when you're doing 45 mph around the track.

Just a random thought, if they can make plastics that are strong, impact resistant, can stand temp extremes, and can save lots of weight, the most logical use it seems to me would be one piece pickup truck beds.

Maybe thats a hard sell, but if there is no drawback in strength you could probably make them cheaply and take a couple hundred pounds of heavy vehicles as long as they are not prone to cracking with a heavy load.

They aren't as strong and that's the problem. You have a space constraint on a vehicle so you have to keep the bed walls slim yet strong, as they help handle the load in the bed as well as brace the frame to a degree. Plastic that is strong enough to handle a 1000 lb load slamming against it would probably also shatter in the cold where metal would just bend (or merely flex).

However, that's why plenty of people put plastic bedliners in their pickup. It handles the loads without incurring a big weight penalty or scraping up their paint in the bed. A thin sheet of plastic protects the bed without much of a weight penalty.

I don't get why all the young folks are in such a rush to get around the track anyway. A 10 minute lap at Sebring is pretty relaxing.


I agree....if you're on a bicycle.

Pickup trucks are already front-heavy too. We'd be shifting the center of mass forward.

Meh, whatever weight that is saved with the engine will be replaced by some federal mandated nanny system.

i have a better idea, redesign an engine that doesnt exert most of its energy in the form of heat rather than kinetic power

Easy to say. You add a wink like nobody realizes engines produce heat.
