Anyone going over 200 mph???
 

Just curious if you guys go 200+ mph in a '71 Chevelle. I want to do some road racing type stuff. I am thinking about changing the trans or gearing to do this but am wondering if anyone has any pointers. I might have to swap to a 6 speed unfortunatly, :( but I guess that comes with the turf.
My concerns are wheel bearing possibly failing due to the speed they will be turning and possible lift issues. It will just be for the quick occasional blst and will most likey not be a sustained speed for too long.

What do you guys do??

If you have a wife and kids, first thing you should do a get a good life insurance policy, ;) .

I'd check the rules on what is required to run 200 at such and event, build the car to those safety specs, then worry about power/tranny/gears.

I do 150+ on a pretty regular basis and have had 0 issues so far.

As far as safety, It is just more of a daily driver type street car that I go to shows in, but I like to play around. That would really suck If I needed safety equipment.... I never thought of that! :(

I have run over 200 at Silver State many years ago. There is a huge difference between going 150 to going 200. Everything changes especially in the aerodynamics , suspension dampening ect. On a heavy car like yours, don't skimp on ANY suspension peices at all. Remember even if you replace all the "wear" items with new stuff, it's still old technology and was never ment to go those speeds. Safety equipment is a must. Good luck and be safe..

If you really want to go that fast, you might want to talk to a shop that builds Bonneville cars for some pointers.

Uh.....duh?

Also, if you're ever on a public road near me and I hear about/see you going that fast, I would not hesitate to call whoever necessary to have you thrown in jail. I'd like to see a "quick blast" to 200. :soapbox:

As said, get a good policy and the rest of us will just hope you don't hurt someone else.

just put bigger turbos on it and "say" it can go that fast. Most people wouldn't want to get in the car with you to verify it anyways. Hot Rod had an article a while back about a black mopar that they modified to go faster. I remember them saying that the aerodynamics of the car made it very hard to get past 150 or so.

This is something I am tossing around. I do not drive this fast on the street most of the time. Keep in mind my car goes 0-150 mph in 10 seconds from a standing stop, so If I am already going 75 mph on the interstate, I get up to 150 mph in hurry, 5 seconds maybe?? I do not drive this fast on any populated street where I could hurt anyone including myself. I can get up to 150 and slow back down before most people can do the quarter mile, so dont go thinking I am a wreckless driver and calling the authoritise(sp) just yet. I drive very safely and have a clean record.

I have nevr gone 200 and that is why I put up a post asking what people who have done it are doing for stability and safety.

Are these races mostly blasts up to 200+??? I would assume so being that you have to slow way down for some turns. It is way easier to accelerate to 200 then to hold it at 200. :wow:

Does 200mph on W2W's chassis dyno count? :D

200mph video

Your car runs 9.99 or better at 150+? Got a video?:unibrow:

Why? It's not safe unless you're under controlled conditions (and on a closed course).

200 mph is 293 ft/s. That roughly 1 football field every second. EVERY SECOND. 150 mph is still 220 ft/s. The important factor to consider is not that you can get to 150 mph in 5 seconds but how much distance you're covering in those 5 seconds. Your stopping distance from that speed is much longer than you think it is, too. Even an unpopulated road will have something you don't expect - maybe not today, maybe not tomorrow, but someday. I'm sure you're careful about it, but at your power level you have an incredible responsibility to those around you to keep it under the hood. The fact that you don't have a cage means that you probably can't even take your car out on a track because you'll never get through tech. Think about that, too - racing organizations require these safety items because at the kinds of speed you're capable of, things happen very quickly. All the parts in the world won't save you once you're out of control. And don't worry - I'm not going to call the authorities or the authoritise anytime soon.

I'm not against you trying to go 200, you just need to go about it the right way.
