What would you do with your aero gains: Spend them, or save them?

[MetroMPG]

Let's say hypothetically that you improved your car's aerodynamics enough to see a 15% FE improvement at 90 km/h (about 55 mph) compared to before the mods.

In other words, you could now drive somewhat faster, and still get better FE than you used to get prior to the mods. Or you could find the new, maximum speed at which you achieve the same FE you used to get at 90.

So, what would you do?

Take the fun poll!

Dude, max FE FTW. I have something to say but right now I'm looking for a connector to fix where I messed up the push button start and I might be done wiring on my tuck so no time to think!

I thought the thread was about what would you do with the money you save from the aero mods. I would get ****faced. Nothing like hugging the toilet to celebrate the end of a work week.

It depends, if I'm still on diesel, then mpg FTW. But if I can get a recycling contract with a restaurant and run WVO, then it'll be 50mpg@70mph on free fuel FTW. Although I might try and see how much I can eek out from a tank, that's always fun.

DEfinately reap the rewards... I'm not in much of a hurry to get anywhere... I can take my time.

I would drive the same speed, reap the benefits, and buy a ferrari enzo (7mpg) as a reward for my innovations.

[krousdb]

I would find the speed where the increase in FE would be cancelled (via A-B-A testing) and then do a cost benefit analysis and then a Pugh concept selection.

I'm going to Disney World!!

I would drive faster down big steep hills.

I would drive faster down big steep hills.

You'd have little choice in the matter, unless you were going to use the brakes more :)

[tomauto]

The pugh chart takes a while to make, but the answer is very clear when you are finished making it. How much do you really use the Pugh selection krousdb? In class the professors said time and time again...

[The Toecutter]

I'd do both with my aeromods.

In normal driving, I'd simply reap all of the efficiency benefits. When I'm in the country with a few friends in the middle of the night hooning around, better aero simply means better top speed if gearing allows.
