968 01E will hit aprox 330kmh at 7000 if I remember correctly

a8/a6 01E will hit 361kmh at 7000rpm

some of the 01E models has exactly the same speed(gearing) in 5th as 016R

Yea, but didn't the Yelloe Bird go well past 200 though????

Also, 5,950 vs 7,200K makes a big difference.

CTR did ~212, as Anders noted.

As a further comparison, the 996 GT1--which is very much a full-race car with the minimal required equipment for road license--topped out at 193 mph.

Even with the proper gearing, you will need to push out significant HP to achieve 200 mph, and even then I don't know if the car will be limited by aerodynamics. Or what modifications to the body, suspension, etc would be required to achieve 200 mph.

But you can give it a shot and let us know how it turns out.

Just get one of these older ones or look at some newer models.

The 01E bolts up, if you look at the Audi bell housing it's the same as the Audi 944 bell housing (as in it has weird holes for the started and clutch, etc). The Audi/Porsche 968 01E bolts up to the 944 torque tube also (I know, I did it yesterday). They are both good for over 200mph if you turn ~7500rpm and have a large tire (295/30R18, 285/35R18), and of course, the power to get there. I would not consider even doing it without a decent front splitter/undertray and a rear wing to match. I'll take the extra drag and potentially not get there over having the car float around on me.

The top speed of the Gt1 was largely as a result of lots of downforce as far as I understand it. They could physically go faster but, for some reason Porsche restricted them.

To hit 200mph it will either take a ton of power or something like a 10 mile straight with not so much power! In reality, it's going to take a ridiculous amount of power due to time constraints. You're not likely to have enough time to floor it and hit 200mph without either (A) getting caught by the cops, or (B) hitting a K wall on a track and flipping end over end 72 times because you're on stock brakes trying to threshold brake from 200mph into a 90 degree turn! IMHO, 200mph on the street (pretty ridiculous to be doing on the street IMO) isn't realistic for anything except something like 800-1000+whp street cars as once they'd get traction, generally the sheer level of acceleration would get you towards 200mph pretty quickly so you can get back down to "normal" speeds that much more quickly. It's somewhat the same story on most tracks, as long straights are usually only so long.

Just FYI but, I've seen several dynos of CTR's in the past, and it seems they generally dyno close to the rated 469hp though at the wheels, so they are pretty underrated.

there are some differences between 01E from porsche and audi when you look at the pics, I know the one for porsche fits, but wonder if an audi fits as easy, if so. you have a huge source of cheap 6 speeds that will take you to 224mph at 7000

The 928 transmission is big and will not fit without the use of a tiger saw.

IIRC the DEVEK white car did 211 mph with some aero mods, a tad over 400 rwhp (not sure on that one, ask Marc Thomas, might have been close to 450 rwhp) and a final drive of 2.2 (1987 S4).

What year a6, a8 are the 01e gearboxes in?
I did a search on evilbay, and all the gearboxes from audi had three letter codes.

Btw, if anyone is interested in making a 951 trap over 200 mph I would like to join in on that project. I've travelled at 205.1 mph through those traps at the Pony Express but not yet in a Porsche.

Dude, I'll provide the tiger and blades if anyone wants to fit a 928 trannie in a 951.

please read this info on 01E
http://www.elektro.com/~audi/01E/Por968/
http://www.elektro.com/~audi/
http://elektro.cmhnet.org/~audi/01E/

you get 01E FWD in misc diesel FWD audis
a8 even has a cooling loop.

the different cars had different gearsings, some closer and better than others.

The 968 01E definantly won't hit 200mph at 7500. In my 968 I can get it all the way to 7500 in 6th (well about 7400-7500) before it won't climb any more to the 7800rpm redline. I was at an indicated 170-171, which translates to about 162-165 taking into account speedometer descrepancies. Even if I had the power to go to 7800 I would only be at a max of 180-185 indicated. There are very few 951's that will turn 7800 for a 2 minute stretch without exploding .

Amen...not to mention - to go that fast one must not only consider the power required for a narrow body 951 (roughly 375-450 in upper rpm band) but also what it takes to handle & eventually stop it (i.e. brakes the size of trash can lids, all new hubs, arms, suspension mounts etc in case you have to handle a blow out). When you finally get all the required material for a "safe" run up to and over 200mph - you'll have a new car. There isn't any way in hell i'm going to climb into a car with 20 or even 5 year old components for a run that fast. Its just stupid.
