can our cars be capable of going 200mph? i was watching top gear uk and they ran the new Bugatti Veyron Super Sport up to like 258mph or something ridiculous like that and it got me thinking if TA/Camaro's could do it. obviously u gotta have some big hp numbers but could the car take 200mph or would it literally blow the doors and panels off? what do u guys think?

Stock configuration I believe the Trans Am hits the air wall at 162 mph. So in that regard no they won't. You'll need to do some modifications to get to the 200 mph barrier.

You would need mods like the IROC series that raced these cars. It's been a few years (and I really can't recall the year, maybe 2002??) since the series with our cars but I'm sure they hit 200 mph at Daytona and the super speedways.

Yes.

Speed is a function of power and drag - if the car sleek enough (and our cars are indeed "sleek"), and if there is enough available power, then it is possible.

Remember though, the rate of increased resistance to speed due to drag is not linear, it's exponential. This is why the Bugatti Veyron, with 65% more power than a ZR1 'Vette, only goes 50 mph faster.

FYI - Back in the late 80's Car and Driver took a 3rd gen and put enough power into it, via dual turbos if I recall correctly, and then exceeded 200 mph; so, it can be done.

I have a friend who has a 05 GTO and he said that stock, the ls2 GTO can hit 196mph but will fall apart immediatly after. I highly doubt this. Anybody know the real top speed for a ls2 GTO?

With enough power and a few aero tweaks its already been done, search the road race section.


The stock limiter is set at 162, without it these cars supposedly will do 170+mph and end up being limited by gearing more than aero.

JD_AMG

lol... Thats just funnny...
The GTO doesn't have the gearing to go that fast anyway so its not even an argument.
Ls2 GTO should be able to go 170ish without the stock limiter.

1st no aero changes except lowered the car but here is a lingenfelter N/A 383 formula 192.xxx MPH Watch at 5 min 26 sec.

2nd I have a friend that had an 06 LS2 GTO he swore it did 181 mph Dont know if he was lying or not though.

Full splash pan/belly pan, functional rear diffuser.

Plenty of other mods to the engine and drivetrain to make it do it safely and reliably. You don't want a failure when you're pushing the limits, or it'll end up as a wad of scrap metal like that Option Stream Z at the Silver State Classic a few years ago.

Are they aerodynamically capable of that speed?

Not sure about 4th Gens but 3rd Gens have some of the best aerodynamics of any production car. Sharp straight lines are better as opposed to curvy flowing lines(Exact of opposite of what they first thought).

That's impressive. I've never seen that bit of film before, thanks for posting it.

192 in an F-body is craaaaaazy fast.

I highly doubt doors, etc would be falling off of the car if it hit 200mph. In bone stock trim, they can do 160mph. Why wouldn't they be capable of 200mph with more power?

Also someone asked if the car is aerodynamic enough to do it. I don't know as I've never done it, but there is a video of a stock body 03 cobra with a built motor doing 200+mph in the Texas mile.

Are the 03 Cobra's more aerodynamic than our cars?

Yes, with enough power (500whp), these cars are capable of 200+mph.

Leaf blowers send air out at 180+mph. You think a leafblower is gonna hurt your car? Well then, neither is the wind. Wind is difficult to power though, but it's not going to tear your car apart.

But, staying on the road is something else. By default, all cars create lift and actually put less weight on their tires as they increase in speed. This is a big problem since even tiny steering inputs or road irregularities amplified by speed. This is why real race cars have front and rear wings, diffusers, etc.

So, yes, these cars can do it with enough power. Would it be very safe? No.

If you wanted to do it "right," you should get a functional aero package (wing, diffusers, undertray), your car lowered, a good suspension setup, a real racing seat with a 5 point harness, and your car caged. But, if you don't mind putting your life at risk and you've got enough power, the car is probably good for at least 220 before the back tires start to quiver between floating and touching the ground. You'd probably need least 700whp to go 220.

A 800fps shot from a bb gun won't harm your car either but a truck traveling at 800fps may have slightly different results! Same with wind.

As far as the aerodynamics, 4th Gen F-bodies have a low drag coeffecient. Meaning they're quite aerodynamic compared to the rest of cars on the road. youtube some salt flats runs and you'll see the aerodynamics are mostly a factor at record setting speeds well over 200. For a 4th(or 3rd) Gen F-body the factor of 200mph is a matter of power, power and power.

<--- That's there cause my daughter pointed it out!

ZMX

BBs and trucks are a lot heavier and harder than air. Air from a leafblower and air from going fast are the same thing.

...

Air is a fluid. As such, the force required to overcome wind drag increases with the square of speed. This means power (force * speed) required to overcome wind drag increases with the cube of speed. 2x speed = 8x wind drag. To do the math yourself, just remember to use the cube. 1.5x speed? 1.5 * 1.5 * 1.5 = 3.375 times the power to overcome wind.

But, let us not forget rolling resistance! As speed increases, rolling resistance becomes decreasingly significant (as wind drag increases much more quickly), but it still plays a part in drag. Bigger tires, lower tire pressure, and softer compounds all increase rolling resistance.

Good find.
Funny that suspension setup (konis + a bigger font bar) is exactly the same that was recommended in the thread I was talking about:
https://ls1tech.com/forums/12769352-post16.html
And as you can all see, there are a few minor aero tweaks.

This thread is ridiculously stupid.

Any car, given the right modifications, can do 200+ miles per hour.

My point with the BB vs truck was same as saying leaf blower compared to wind across your whole car. The 200mph wind from my leaf blower doesn't knock a man over but 200mph WIND from a tornado surely will. Volume of fluid matters. Mass times speed. And like I said, it's a matter of power for our cars. Production vehicles don't get MUCH more aerodynamic than F-bodies. You could add things that help aerodynamics at speed and theres things that willl hinder it. (ie too much down force increases drag at speed) We aren't in disagreement and I wasn't intending to condescend. My point was based solely on how the volume of moving air seemed irrelevant in your post. Other than that, we are in full agreement. No?

ZMX -

There are a number of individuals here who ask questions to learn, and "WS6dude99" is one of them. Your post was only half right, and "Swiat34" pointed out the portion which was in error. I do not expect you to fully understand the concept of civility on the interbox, but an attempt would be appreciated.

(To all others, please forgive my ZMX-focused diatribe. I apologize for the thread hijack.)
