Anyone going over 200 mph???

Drag increases with the square of speed. I'll see if I can find a link to an applicable explaination.

Here is a fairly simple breakdown:
http://en.wikipedia.org/wiki/Drag_equation

It does not however account for lift induced drag and the resultant effect of changes in frontal area.

i have been to a speed limited 186 mph, with nothing more that a cowhide and a helemt for saftey

I have to say f you have the need for that type of speed, Go to the Richard Petty Expierence. They'll take you upwards of 185 and will even let you drive after you've done the class. Or go skydiving.

Yeah, but you're a nutball!

This is not the response I was hoping for. I have never been much above 150 mph in my car and was hoping it would be easy to do. I sometimes take for granted the the way the car drives. I get up to 150 mph so darn fast, that it does'nt really seem that fast.

Sounds like some of you have gone this fast and it sounds hard to do I guess. I also realized that it can not be done without going to a 6 speed trans, and a 6 speed will not hold my power for any length of time. without losing acceleration, I can only do 190 mph with a overdrive anyway.

My new plan will be buying an adjustable rear anti roll bar, a Gearvendors or a 4l80E, and go from there. Anyone use a Gearvendors???

What do you think the best adjustable shocks are?? Hal adjustable??

Nitro,

I would be concerned with suspension and brakes, but aero concerns will probably hold you back more.

You should sign up for the F Body weekend at Road America this October if you want to get a feel for sustained high speeds.

The motor would have to be set back into the chassis. The only muscle car that I can think that went over 200 mph is Big Red. http://www.hotrod.com/featuredvehicl...vrolet_camaro/
Also you need to wind tunnel test your car to see on how you can improve the aerodynamics. Can a 6 speed handle 1000 hp? Yes, but it has to be custom built. Rockland standard gear is building custom 6 speeds that can handle over 1200 hp. Actually, I heard it was up to 1500 hp, although you would have to contact Rockland Gear.

You car has not even went 10.50's yet. Sorry, the converter breaking on the first pass doesn't count. My friend's fastest street 69 Camaro runs in the 8.50's with around 1500 hp. He hasn't hit the 200 mph, but he is looking to go faster in time not speed. Also he prefers to remain consistant in his times.

E.T. has NOTHING to do with top speed. and I am sure your buddy could EASILY do 200 mph if he stays in the gas a couple seconds longer provided he had the extra gearing. What do you mean by this comment? 1000 hp is 1000 hp, That is enough to push just about anything to 200 mph.

Ans what do you mean my converter breaking on the first pass does'nt count?? I never made a full pass, the car went 10.50@137 letting off the gas, it obviously has much more in it. Are you saying my car does not make the power I say it does or what?? That is a little rude.

There was a video on yenko.net last week(I belive it was yenko.net) The video was of 1 of the new Z06 Corvettes, Passenger video taped the instrument panel (speedo & tach) It went from 0-MPH al the way through 200-MPH and was accomplished pretty quick.
Poster stated that the run was done on a military base runway and used up almost 3 miles.
I tried to find it and link it here but was unable to find it again. Maybe someone here saw it and can post it.
Back to the point, Guys in Corvette were only wearing Helments and firesuits from what I could see. also had the disclaimer of (Professional Drivers on a closed circuit)..

I don't think he was saying that. I also don't think 10.50's at 137 letting off will equal 150 mph trap speed. That is usually an 8 second e.t. to trap that high.

The last Road and Track standing mile had several heavy hitters including a champ car, 1000+ HP Viper, twin turbo S7 Saleen, a couple other race cars and exotics (modded), etc. There was not a single car in the bunch hitting 200 mph in 3/4 mile like you think yours will do. There were three that could hit 200 in a mile, and 11 that were 154-185 mph. The three were the TT Viper at 210 mph, the TT Saleen S7 at 205 mph, and the Lola champ car at 203 mph. You have the HP of the Viper, or something close although he'll have you on torque, a few hundred pounds lighter, and much more aerodynamic. The Saleen and Champ car are lighter still.

Your car may have the power to make 200 mph, but not in a mile in my opinion. But I do not think you can control the car at that speed either without some big help in the air management area. I do not know what changes would be required, but HP alone will not get you there, at least not and live to tell about it. Your car is dangerous compared to most in that it has the HP to get you beyond what the car can handle. In other words, the standard 500-600 HP Chevelle would be limited to say 160 mph as he would not have the HP to push the car shape any faster. He might be near the limit as far as lift, etc. but not over it. Your car will push past that on power alone and will get into an area you do not want to be in.

The goal is cool (except for the street part) and I hope you pursue it. But please do it with the safety equipment required and work your way up in speed testing the handling and air management changes. I would be talking to the Bonneville guys as they go very fast in stock bodied cars of all shapes and sizes.

I've 170 mph that way nothing like it.It more adrenline rush on a bike than with doors around you
