They have to make 200mph, arent they having 2.73 gears in them? I did 173 with my 2000TA with a cam and a few other mods, and 2.73 gears, it really didnt take as long as I thought to get up to that speed. I also have it on video for the B.S.'ers

6th gear is an overdrive gear. Top speed is never achieved in a C5 or C6 Corvette in 6th gear. There was a similar thread about this over at the Corvette Action Center: http://corvetteactioncenter.com/forums/index.php

I would believe that the top speed in Europe will be easier to hit because they have a better Premium fuel to buy. So, GM can use a Euro Tune or something like that maybe, and then use their 96 or 98 (forget what it is) and that would allow for some more timming and they can lean out the mixture a little for some more power. That should get 15-20 HP needed for 200 mph easy.

No sir you have incorrect info..in Europe to be considered a super car you need to be able to run 300 KPH..that equals 186 MPH..the 2005 C6 coup with a six speed manual trans with the Z51 performance handling package goes 186 MPH..the gearing in the transmission is how the car attains this speed a long with a .28 drag coefficient..so the C6 is already considered a super car in Europe..GM did an advertising campaign presenting this info last year..

5th is over drive and 6th is over over drive...

Probably wouldnt go any more anyways, though...it does take longer than I thought to get up there...you dont accelerate as fast once you get to like 140....

My bet is that the average C6 Z06 will run 203 to 205 MPH, but that after a century of dealing with lawyered-up idiots, GM's attorneys know they'll get sued if they claim 200 and somebody's will 'only' do 199.

I checked and you are correct. 100hp @ 100mph would need to be 800hp @ 200mph.

check his sig.....hes been up there a couple of times.
As for the C6, I think with a tune it could break 200, if not with better air. If for some reason that dosent work you have the option of lowering the car or taking off the mirrors, if not just taping up the seams.
Racehead, im curious as to what you you do to keep things going smooth at thoes speeds. I was thinking the camaro had the advantage up at thoes speed with the ability of it being easier to convert it to a front breather, eliminating the air dam and lowering the car more. Id also imagine you prolly have either 0 toe or toe in to make it not as twitchy up there. Also wouldnt mind hearing what aero mods could you can do to the trans am without really cutting stuff up.

toe-in makes the car more stable, no toe or toe-out makes it more twitchy. caster also has an effect on the feel.
lol@sig quote... U would have lost your ***** too if a critter ran in front of you at that speed.

Even on the old set-ups when I would be down 30 or even 40 rwhp to his car, I walk him at high speeds.
He would create a 3 - 5 car lead through 4th gear and I would make up ground, catch him, and put 2 -3 CARS on him in 5th

Now I can emabrass his car with my rwhp aero.
I like the WS6 aggressive hood but I LOVE my aero-dynamic hood
