I'm thinking if the car were low enough to the ground, with enough downforce, I could see the Fbody chassis doing 280. It's one of the most aerodynamic contemporary cars out there, and the top is very low, which is a plus.

The downfall is the air that goes through the radiator and lifts the hood.

The Firehawk vents are functional.

425-450 rwhp is enough to run 195 in a lowered F-body.

Don't ask me, ask the engineers who did their homework. Check it out in motor trend or any other reputable magazine. 2002 camaro SS coefficient of drag .34. 2004 chrysler town & country minivan C/d .34.

Looks can be deceiving, there are many cars more aerodynamic than ours that by a glance look like there's no way in hell they could be aerodynamic at all. For instance: a honda accord has a drag coefficient of .30 in comparison. How about a VW Jetta also sitting at .30? That's almost as aerodynamic as a 'vette mind you. Hyundai Santa Fe (a frickin SUV) has a C/D of .34, same as our cars. A BMW 3 series .32, that's basically a cube on wheels. A FORD FOCUS set C/D records with mid .20's.

Don't believe me about flying off the road at high speeds? Search google for "CLK-GTR wreck" and I'm sure you'll see a vid of that car flipping up into the air once it hits a certain speed because the spoilers weren't calibrated correctly. At around 140 our cars become unstable and start lifting like a wing, hit anything higher without the proper equipment and you WILL come off the road and find yourself getting an up-close and personal look at a wall or tree at 160+ mph. Not a position I'd want to be in.

Wider tires add to the drag cD. Our cars come with pretty wide tires and that slows us down.
I am not sure if the 92 Formula by Kugel/LaFevers still holds the top speed record for factory bodied car, but they set a record of 300mph with an exit speed of 308 I believe.
This was a 92 Formula with the 87-90 Spoiler installed since it is very functional.

On a side note, I had my old 86 Trans Am up to about 160mph and my car felt very stable at that speed.

And how long is that? I have 18 years driving experience, 13 years with a 12 sec 2nd gen Camaro and over 2 with the present Camaro and no telling how many hours driving commercial vehicles and I still won't take mine that high. Not until further upgrades, and my suspension is decently modded at the moment.

W rated tires of what make? I wouldn't trust a budget w rated tire.

Not trying to troll here (I'd rather not read a post about how you lost control of your car), but your brake upgrades listed "drilled slotted rotors" are nothing but driveway jewelry. With the temps from high speeds, those pretty little drilled holes will develope some nice small cracks that will grow. Did you even upgrade your pads with something that could take higher temps?

Not really, actually the third gen cars ae more slippery. You dont see many 4th gens on the salt flats.

And if anyone thinks 450 rwhp in lowered f body is enough to run 195 mph NOT.....think 700 hp nascar, windtunnel massaged body here.

first off... who cares.. your NUTS if you go 150+ on the streets... i did it once.. and still dont know why i did it... after being in my wreck(at 70mph) into a tree(off the interstate).... i doubt ill ever go over 100 anymore... just bc the car can go that fast... doesnt mean a pothole/dirty/blow out wont screw you just as hard...

my car felt pretty stable 160+mph, i hate doing curves at that speed though. Dont wanna hit the brakes too hard and skid. Every bump is exaggerated but can still feel the gs while turning. A member on this site with head/cam lt1 was clocked at 183mph, he says could have gone faster with nitrous. I think with 400rwhp, 190+mph is attainable if the gearing is right.

psychocabbage

Its your video I was showing in my link.. hhaha I am hosting it on my site.. haha

chuck

I missed that lol.

For the record, I do not advocate triple digit speeds on public streets. It is one thing to risk your own ***, but it is not ok for you to risk someone elses w/o their consent (passnegers lol).

If you have ever looked under the back end of an F-body and seen the huge fricken parachute of a back bumper cover you would under stand why F-body's have a .34 drag coefficient. Along with the front air dam, to scoop up air for the radiator. Not to mention all the body seams and other areas where body panels stop or meet.

Also if they wanted to lower the drag coefficient they should have made the back hatch a more abrupt drop off. Like on the C5 Corvette, this way the air makes a cleaner brake from the vehicle and doesn't swirl around the back of the vehicle and create turbulence which causes drag.

or another vehicle who gets smoked by somebody going too fast. According to the stats though, its not speed that kills (well it does, but usually its alcohol, and then mistakes at intersections).

Zepher

If he hit 183mph with, let's say 400hp, he'll need to double his hp to hit 200mph.
Pushing past the 180mph barrier takes a lot of power.

med_reject

Going by the laws of physics, if he doubles his horsepower, his top speed should increase by a factor of the square root of 2, i.e approx 1.4

Ofcourse we need to factor in the internal friction losses which will be higher on the axle which will be rotating faster, and the rpm as well which may be higher, but at those speeds, the most significant factor is drag.
