I was afraid I'd rip my soft top the wind noise was getting LOUD!
However, this was not on the I25 between COS and Pueblo, speeding on the I25 late at night when there is a dearth of traffic would be wrong!

 

I've seen 162 in my slightly modded Lt1 '92 A4 stock 2.59 gears with the wind at my back on a slighty downhill closed course road no people or animals got hurt.

 

I wish I could find an old picture I had of my antenna on my '86. It had a permanent and noticable curve to it from some high speed "track" testing. Someone who was also familiar with "high altitude" runs was snickering at the next corvette meet when he saw that.

 

Ok, I guess I hadnt realized that the topic would turn the way it did. I was simply questioning what the top speed of a LT1 6 speed car would be. I am not trying to perpetuate speeding on public highways. Yes, I did do it on a stretch of long flat state highway (NOT INTERSTATE). I know the road very well, & there are no on or off ramps nor side streets entering the highway for a 4 or 5 mile stretch. In addition to that, you can see the road very well & whos on it with you. In this case it was no one at all. I was alone in the car & on the road.

I really dont need anyone to tell me that that was breaking the traffic laws. I know that & had something happened to me or my car, or both, thats my cross to bare. I have been driving for 23 years & held, for 10 of them, & still hold a class A license. In the time I have been driving I have seen 100+ less than 10 times on a public roadway. Most of the 10 I was a teenager, which answers why I did it in the first place.

Like most of you, I am very intimate with the condition & workings of my Vette. My tires & brakes are brand new & everything is in excellent working order. No that doesnt make it ok, but, for the PC crowd here, you should sleep well knowing that I dont do this on a regular basis at all, & when I do, its under the safest conditions & never involves other people on the roadway.

I would have answered my own post here alot earlier, however I was in NY visiting my family for Christmas.

And one more thing, street racing by any modern standard is nothing like what I just explained. Todays moronic kids race thier Japaneese pieces of crap right down the middle of business district areas, & have a total of 2 years driving experience, & to top it off, have NO knowledge of thier cars condition or its limitations. To compare the two is idiotic.

Have a great evening

 

This kind of stuff gets locked quickly in the c6.

 

Thats good to know, for while I thought I was missing something. »keith

 

to answer the question at hand (surprising no one has it, either), but a 1992 LT1/6sp as tested by Road and Track hit 161 in 5th.

As stated, 6th is too steep to overcome. For that matter, a Viper, with the same basic gearing, can't overcome that much overdrive.

 

It would be interesting to know the effect of altitude on top speed. You're giving up power to the thin air, but you have much less aero drag due to the thin air. Which counts more?

A POS 4 cylinder BMW I had would always run easy as soon as I hit western Kansas, but I never tried a top speed run with it out there. The 4 cylinder Toyota pickup I had couldn't keep up with traffic at 6000 feet. I'd really like to know how my Vette would respond to the thin air.

 

Fixed

 

it would have an effect, but you can't compare a Toyota R22 motor to an SBC... that's apples and oranges.

 

OF course you can't compare the two. The mention of the Toyota is to demonstrate that even 7000 feet really kills the engine.

But my real question is which is more important in effect, the loss of power or the lower drag. My guess would be the lower drag would boost the top speed potential of a Vette, since the drag increases by the square and not linearly.

 

160 mph @ 4500 rpms. I'm too scared to do it again.

But here was my top speed rice run when my cajones were a lot bigger.

Well put!
