I have a few no speed limit autobahns here. The traffic flow allows for high speed driving. I recently got 508 miles from one tank. That was a lot of cruising at 75mph. I will just do a 3 mile sprint or so.

oh how we americans envy you and your autobahn...Sad


I am an American from Chicago. I just been here for half of my life. Look at one of my autobahn videos. See my post above for more info. My old video can be found on youtube or google: Google "Cobra, carrera, autobahn".

Keep in mind that was in my old 320 hp '99 cobra in 4th gear - no turbo or supercharger. Now supercharged and pullied with my 2003 cobra - plus a few other tricks - over 525 HP/503 lb/ft rear wheel torque.

1st gear at 2500 gets better MPGs than 5th gear at 2500, but thats a slow way to get where you need to go.

2500 rpms....how do u manage to get 2500rpms = peak efficiency?....if ur at 2500 rpms in 1st....ur gonna be going a lot slower..there are a lot more things affecting mpg. u have to combine the speed, the rpms (which then generate what gear ur in. and 2500 rpms in fifth...ur usually going faster...so calculate it this way...i drive for one hour at 2500 rpms in first at about 20 mph...u go twenty miles. do that in fifth at about 70 mph..u went seventy miles..and thats with the same amount of gas. dont floor it b/c u stay in the lower gears too long, thats y city mileage is worse than highway...

2500 rpms....how do u manage to get 2500rpms = peak efficiency?

let me rephrase that, engines like to run at 2500, anything lower and they try to run rich, anything higher and they try to run lean(computer control and better technology has made it less obvious, but its still there at some level)

or at least in my experience, i have an old nova with an exhast leak(right infront of firewall so you could smell every drop of exhaust, which is why i drove with the windows down most of the time) and at 1500 you could smell the unburt gas. at 3500 you could definitly tell it was leaning out...and i had a corsica, that had the same problem(though it didnt have a tach you can still tell) low RPM rich, high RPM lean. 2500 was the magic number for 2 cars, or maybe it only chevys. or maybe my chevys were weird, i know the nova is, and the corsica was a POS. sold the corsica for 300$ and ripped those people off. eh, it was a good beater. ah, nostalgia. anyway, 4000-4500 are ussally the most powerful, and 2500 is generally the most effecient. again this has been my experience. i could be way off. but i like to think that my experiences have been worth something.

Sorry to bring up an old thread.

Never worry about that here unless it's a hate thread.  Grin

I will see what the avenger can do.

Just remember PLEASE to have your passenger [preferrably] record your speed at 4500 in 5th.

peak mpg = lowest resistance, lowest revs, most power, fastest wheel spin.

Ok I see you watched my video. I hope you didn't leave any hate mail in you tube quotes. I find that quite funny. I just say they all were drinking haterade when they watched the video.

No worries. lol. Good job btw. with the Avenger, if your passenger is in the 1/4 of a backseat filiming over your shoulder, that will give you the best shot of both the tach, speedo, and the road. If it's at night, that will give the best shot also HOWEVER, due to animals, i DON'T recommend finding this out at night. lol

We don't need any "Rambo Bambi took out my Avenger" threads.  Cheesy

Since youtube reduces the quality of videos unless you PAY them to have the vid in High Res, you can email the video to my email account. When you have the video recorded, send me a PM and i'll give you the email to send it to.

Well enjoy this until I find a good time to get out on the autobahn at stretch top out the Avenger:

http://media.putfile.com/2003-SVT-Cobra-and-Ferrari-F430-fun

I will either have a passenger or use a tripod. The Avenger is not stable at high speeds. Up to 120 MPH its ok but when you travel this fast you always need room to STOP and sometimes unexpectedly. My Avenger does not have ABS so please be patient. I need low traffic and dry roads. My Cobra can sprint up to 160 - 175MPH in a fairly short distance so I may add a few videos as well for your entertainment.

Remember to be safe and keep your driving records clean. I am safe also. It may look easy but I have been driving here for nearly half of my life.
