The apply servo just uses a smaller area in OD because of the ratio delta.
But what will happen in an extended WOT run is the torque converter is unlocked and will overheat the transmission and it will fail.
As far as top speed is concerned the 3.42 will actually allow you a slightly higher top end then the 3.15
BTW the PCM can be programed to give you 4th gear lock up at WOT.
Just let me know when and where you plan to do this
run so I'm not in that area at the same time.

Well...
Many different answers to different questions. LOL
I was wondering if its possible to run WOT in OD. I'm seriously thinking about going to 3:42, or maybe even 3:73, bu I don't want to lose a lot of Topend. Not that I'll be using it often, but its nice to have in your pocket if you need it. Brochure say 175 with the 3:15 A4, just wondering if thats truth. With a 3:42, what would the TE be? A post said you can go faster with the 3:42? Definitely quicker, but faster? Due to tq band?
TIA,

Whoa......just a minute here! I thought I had the need for some speed. I need to understand- 2 of our esteemed CF Members have traversed speeds of 168 & 175 respectively in C5 Verts?
Must one wear those astronaut diapers while going that fast? And, where in the U.S., other than the Salt Flats or a venue like Daytona Speedway, can one travel at such speeds without attracting the law? And, what is your strategy should a tire blow and the car flip over? Just curious.

Not as bad as you think
Rickman and elgallo,
It is not as scary as you might think. It is something that you must pay full attention too. So no diapers. I do run those speeds and a lot higher on a regular basis. At these speeds you are not exceding the ability of the tires. I am well aware of what can happen with tires. In fact when people start to talk about wanting to hit the magic 200mph, I post the next picture and tell them to really think about what they are doing and prepare the car.

That was at 204mph. Also all the damage was done by the tire. We had no impact. Both myself and navigator walked away with out a scratch. it is called Open Road Racing and anyone can do it.

I am going to get flamed by the "take it to the Track" guys, but not all of us have a track within a realistic distance. In Idaho we do have alot of straight empty roads. It is all about picking a safe spot that you are only risking yourself. So the 168 in the vert with the top down was on a 4 lane divided highway with no one else around.

170 comes quick even with a few little mods, LT, small cam, intake, give it a clear path of straight tar of about a half mile, maybe 3/4 of a mile, when you are already at 65, and you can be there.
I am one of those people currently building my car for the 200 mark. It will be accomplished even knowing the risks. I have had the bttom end forged, APS twin, built Stage V RPM tranny with the G-Force 5th and 6th, fully built RPM rearend, full coilover suspension, big brakes, and it will be riding on Michelin PS2's. It has been a goal for a long time to build a car to do this so I'm happy to be working at achieving this goal. Now 200, that takes a lot of realestate!!

With a 3.42 you can achieve a slightly higher top end because of where you are on the HP curve. However the theoretical top end would be slightly lower (around 10 mph). And you would need about 10 miles of level road to get there.
The A4 in my car is set up to run 4th gear lockup with a 3.42 axle, I have no idea what the real top end is, but 160 comes up real fast with 10lbs of boost.

Jeff,
www.openroadracing.com actually sounds very cool and much safer than what I originally thought you guys were doing.
However, at least the Grandsport-looking C4 you wrecked was a Coupe w a rollbar. Aren't you concerned about flying at 170+ mph in a C5 Vert w no rollbar? I assume you are wearing a helmet and your life insurance is paid up.
Btw, did insurance cover your loss on the C4?

Are you kidding??
There is no insurance in racing!! You pay out your pocket
Do you really think a helmet would make any difference if you flip a vert at any speed? The 168 was not on a race course.

I always thought that was normal
Oh wait, maybe I was in my chevette
