He only had to hit 80mph cause of the fluxcapcitor, I dont have that so I had to hit 200mph but I still passed him

 

You must have missed this.

I know about that site but its way off. I know the car will not go 134 in fourth gear and or 200 mph at 4500rpm in 6th. This site makes no sense thats why I was asking you guys.

 

Edit:
Sorry, I am confused. Are you asking us about what could be wrong with the car? Cause the site should be accurate.

 

guy has a dyno near KC,(don't remember name of place) has a bullit says he owns the fastest car on the Dyno, at 165, well Bad Monkey (my brother) dynos his slightly modded 99 Vette, Dyno shut gown at 200mph. With his new Vette with an ATI, in new york near Ithaca got speedo around 193, Targa top off wnidows down LOUD AS A *****, well slowing down got pulled over for a 93 in a 65. Lol, cop asked why we were speedin, dumbass replies "we weren't, we were slowing down

 

Those are the speeds our gears would top out at if the car were sitting in the air: meaning, because of the extra force needed to pull the weight of the car through the ever-increasing wind resistance, our cars don't have enough power to max out each gear the way they would if the car was lifted and the tires spun freely (unloaded).

And those calculations are pretty darn accurate: axle ratio of 3.42, 6th gear ratio of .5, 1800 RPM's at 80 MPH (on dyno), is just about right on, because when I'm driving in 6th at 80, the RPM's are at about 1900.

 

I've had mine up to about 140, but haven't been that quick since. I hit 110 and 120 every now and then, but even that is still rare.

I remember hearing about a guy on LS1.com way back when who had his A4 2.73 geared Z28 to like 175 on the dyno.

 

Yep, theoretical speeds assuming the car has the power to equal the drag forces at whatever speed. Air drag alone increases by four times whenever you double your speed, so going fast is not easy and requires much more hp to only go a little faster. So dyno speeds mean little, since most of the load at those speeds is due to air drag.

As an example, it takes about 125 rwhp to go 100 mph in an fbody. But to go 200 mph, you need about 500 rwhp.

A stock six speed LS1 car has the power to hit the rev limit in every gear except 6th. If it had the power to max out in 6th gear, the driveshaft would probably fail first due to it's critcal speed being exceeded. Overdrive is a bad thing for high speed cars; you want to gear higher with axle ratios, not the tranny.

 

thanks guys for clearing everthing thing up I thought about this and figured the same thing. So now one more question how fast should 5th gear take me to.

 

I hit 155 at the top of fifth gear on my stock 3.42. Makes me wonder what it really would have done. I'll never know now. I beleive it would have done around 175, I think.

This link exists, in part, so that you don't have to ask that question. You just use that calculator.

Of course, when it comes to top speed how much power you have comes into play, but this gives you theoretical values.

 

Assuming an M6, axle ratio of 3.42, rear wheel diameter of 24.94 inches, rev limiter at 6200 rpm, and an engine with enough power, you could go 179.3 mph in 5th gear.

 

Hey, i went 130 in 4th gear in my z06. I was only at 4000rpms. It has a six speed tranny. It been slightly modded though.

 

A4 with 3.23s top speed is 159
M6 is 163 I belive

there, now there is no need to go that fast and kill yourself

 

CAL and BLKZ28 I dont care theoreticaly how fast it goes I want to know have fast people have been in 5th or 6th. I've been to the website millions of times.

 

I had my old pewter car to 145 twice, once stock and once modded. 130 numerous times though. I have had my current car to 135 twice and 145 once. All of these runs were on the same stretch of country road with no houses around. It's a two lane road in not all that great of shape really. The actual straightaway isn't even a mile long, I just have a decent speed coming onto it. I would like to find a better spot that is smoother and longer, and hit 150+

 

I did a top speed run in the 99 cobra- Burried the speedo past 160
This Cobra has hit 150
The 00 Z/28 was at 150 as well.
The Ninja- 165 for 45 miles!!@ 3 am on I 95

 

 

My buddies and I were dumb. it was 3 am May 2001 and we were coming back from Nascar In Richmond at 3am. We lived in Dale City, Va about a good 75 miles. Normally a ride from richmond to fredericksburg is 45 minutes. We did it in around 15.

 

After hitting between 110 and 130 a couple of times, I finally went for it one morning on the way to work. Hit just over 150 and the car had more left in it, but I didn't because there was a curve coming up in a hurry.
