Building a 100mpg consumer vehicle

Did being nice go up in price - or in flames ?

I'm not really an aero guy, but I wonder if there would be any benefit to taking the air from those side vents and sending out the tail via an internal duct. I wonder if that would increase the low pressure in the wake of the vehicle. Just an idea...

Hello,

I've been thinking about the same thing. If nothing else, it would look cool!!!!

I have a question though. "if" I was to follow you and build my own. I would not care about a passenger. So building a single seater with a small area for storage. what do you think of the weight savings and the rough length it would end up being? also just your .02 on that.

The widest, tallest part of the car is for the driver and his shoulders.

From there you need to taper it back. What angle can you taper it back? What is the rise over run for an allowable shape which maintains laminar flow? 10 degrees is GOOD, 20 is not enough probably according to what I have read.

FWIW, there is 40 inches length for the passenger and his legs. I'm pretty sure you don't want to lose all that as the car is going to get pretty short, and short means it doesn't want to go straight very well.

As it is, the car isn't really very long. It should end up right about the same overall length as a 2010 corvette we were comparing it to.

for weight, 150 pounds difference????? Not sure, but not much.

I do better when people politely ask questions.

When someone says "you can't do that - engineers have not approved it", or "You must use cast iron roll bars" or "you should have used a motorcycle with no heater, no AC, no reverse and made it 3 feet longer and your project is all wrong" it annoys me.

I think his (euromodder) comment was directed at those that resorted to namecalling. His (drmiller100) not wanting to entertain every doubt and question and being abrupt about it doesn't give others license to mouth off.

Sarge, go back and read the entire thread.

In each case there are honest questions asked. There were some cases of folks offering opinions that they thought his ideas would not work. There were also cases where they simply offered other options.

Not once did I detect any disrespectful tone in these posts. Not once.

And not all inputs were of the 'you can't do that nature'. Many were just offering other options.

What we got back, in increasing amount was basically, 'shut up, idiot, this is my build not yours'.

Are we supposed to say yes sir, you're right?

Seems like doug just wants to show off his admittedly good skills and have us serve as a cheering section. That is not what this place is about.

I asked politely. Infact, I started my post with a compliment.

I got back the standard 'you're an idiot, build one yourself' answer.

Would it have been that hard to take a moment to give your reasons for why my suggestion was a poor one?

BTW, I disagree with you on all but one of those points.

KLR and DRZ mills water cooled=heat

Electric reverse (some touring bikes have it)

Overall length, I honestly can't say, but, my guess is that you will be pretty close to where you are now, but the seats will be shifted forward some.

AC? You got me on that one.

I do see a few advantages to your layout.

Probably more stable.

Most definitely more crash worthy in head on collisions. Better to have that lump in front rather than being jammed up your backside in a collision.

I reread the entire thread before replying, and I stand by what I said.

I think that's enough drama for this thread. Let's move onward and upward.

Well, I agree with you on the last part of that. Water under the bridge. Lets hope everyone can be positive from here on.
