Is 200 mph REALLY possible.

KartMan · #1 06-26-2004, 01:45 PM

While laying around this morning, I was pondering this burning question. Is 200 mph really possible on an oval. I truly believe; NO!!! I do not ever see r/c cars hitting 200 on a flat oval track. Now, if we could only run these at the salt flats, with a chase car... THEN MAYBEE. I honestly don't believe they will get much faster than 150-160. You have to realize that as speed increases, the drag multiplies much faster. So, you need increasingly more horsepower to go faster and faster. The biggest factor in this competition is having to turn left at the end of every straight.

Let me know what you think about this.

I'd bet it's possible but you would need a chase car because there is no way it will happen on a track short enough to keep your car in radio range. If you could find a track big enough and smooth enough, i'd think it would be possible on an oval.

Micro,
ONLY if there were some seriously banked corners. Not on ANY flat track will an RC car break the 200 mph barrier. That is my opinion. I would love to be prooved wrong.

mgs9 · #4 06-26-2004, 10:46 PM

any things possible, but i dont think we will be seeing any cars going more than 140 this year. people have said that they have got there cars up to 150+ but they probbly have run there car a bunch of times to tweek one run of that speed, you only get 3 runs.
mabey im rong but thats what i think.

IMHO it should not be extremely difficult to have a r/c car making a wide turn radius at those speed.

If you have ever watched 1/8 nitro on a r/c track, you will see that they can take very narrow turn at full speed ( around 70/75 mph ).

As a matter of fact, at my local track, the 1/8 take the turn after the straight full bore and they don't seems to struggle doing it either !

small radius turn @ 70/75 mph should be roughly equivalent at big turn @ 200 mph, but that's only me guessing !

i personally dont think it would be possible due to the fast the tires i dont think would hold up to that kind of revolutions let alone the bearing on the inside of the hubs.... any kind of looseness you have in the steering would be so over exaggerated at that speed that it would have to be completly solid no possible slack at all.as for the body it would have to sit so low at that speed that the suspension when at a stop would be like a 1/4" above ground and as speed increases and downforce is compressing the suspension that it would be dang near scraping the ground.you sneezed and it would be all over.as for turns unless you got some serious angle were talking like a huge bowl i dont think it will be possible as like it was said befor youd have to slow down for the turn you would need a actual track freshly paved smooth as glass about the size of indy i would guess at...as for gearing lol get out the bicycle sprockets and modify them as for the speed run rcca did lomg time ago if i recall correctly they had to have one specialy made for this purpose.maybe i shouldnt be typing this but i dont think it is possible to do so on the ground with a rc vehicle maybe a dragster but i doubt even then would it be possible...

ok so u have a car that can hit 200 and you have the place to do it. What chase car r u going to use? u can't sit in the back of a pick-up. Jump in a Ferrari?C'mon.maybe in the future when radios, motors and tires etc. have the capaility to handle it but not now.

Speedtester · #9 06-27-2004, 07:14 PM

Huh? If I had a car that could do 200mph I would be standing in the stands.
The track is 3/4 miles I dont see any problems with range. The major problem is getting the car to stay on the track.

Daff,
I understand what you are saying, as I am experieced with 1/8 onroad. What you are not considering, is to get up to the 200 hp range, you would have to have 2-3 .21 engines, and a butt load of fuel. What does this all mean... WEIGHT. Your 1/8 scales are able to whip around due to the fact that their weight is very low. I see what you are saying, but I still think 200 is not possible.

rc10gtisthebest · #11 06-27-2004, 08:07 PM

One thing you guys got wrong here is that there are NOT going to be chase vehicles. Your going to be standing in the Flag Booth controlling the rc car. Also most of the Purpose built rc cars have very ****** handling. So they won't be able to negotiate the turn at all.

I believe 150 is possible but not 200. If I wanted to do 200mph I would go to the Salt Flats with a PCM radio with Alkaline Batteries in it So I can use as much room as humanly possible.

Chase vehicles are a bullcrap cheating machine. No record should be consider where a chase vehicle is being used. This is just my point of few.

minitdriver · #12 06-28-2004, 12:12 AM

I based my view on being at a place like the Salt Flats.I did not know a PCM radio had that much range which is y i critisized the chase vehicle.I really doubt that when this 200mph vehicle is made that it will reach 200mph in 300ft.Sorry if my views and arguements don't make sense.I'm 15 and argueing isn't my best trate.

I'm prety sure you could not drive an RC on the salt flats, it would be to loose, and unless it is perfectly smooth (which I highly doubt) you would loose tons of speed from the dust and the bumps. Plus at 150+mph I'm certain you will have almost no suspension to absorb those.

rc10gtisthebest · #14 06-28-2004, 10:53 AM

a good PCM radio can probably have atleast a 1/2 mile range or better.

What wheelnut said about the salt flats is more then likely true. But, if it's so bumpy then how can someone pilot a fullsize car with little to no suspension to over 400mph on it without any complications?

Anyways, if you want to get up arond the 200mph barrier, what track are you going to run on? Talladega? I don't think so, because if anyone has ever seen the surface of any race track, It is alot bumpier and has more cracks, pits, etc. then the roads we drive on day in and day out (public roads). And Irwindale Speedway where this is happening is way to small for anything to be accomplished of that magnitude.

Sorry if this post sounds rude, it was not meant to be, I just wanted to prove a few points.

Because to a full size car (or bigger usually for speed run cars) a bunch of 5mm bumps don't make much of a difference. But to RC cars they might as well be 3 inch bumps as it wont run smoothly on either.

Sparkey_STi · #16 06-28-2004, 11:51 AM

Lol... if you all said no... your all wrong. Theather cars hit 240... eazy. Do a KaZaA or LimeWire search on "Rc car" and all variations of it... you should find a vid where one hits 200..

rc10gtisthebest · #17 06-28-2004, 12:06 PM

Tether cars aren't rc cars. They are model cars with functioning engines. All that happens for a tether cars is they are hooked up to a string, engine turned on full blast and they go around a high-banked circle a ton of times. There really is no "R/C Car" about it. Just like rails are hitting above Cliff's speeds.

Anyways, I guess everyone's proved me wrong with that Salt flats thing. I'll shut up now.. LOL

300 ft. isn't a lot of room.... it's the length of a football field... but the cars will be allowed to approach this 300 ft. area from turn four at a flying start, right? I just don't think it will take these cars a long ways to reach terminal velocity... guess it depends on the gearing, but if someone could calculate the power-to-weight ratio of these cars, I'm sure they'd be in a range similar to top fuel dragsters, and if you gave one of those guys a running start at a half mile or more, there's no telling what they could do with taller gearing... and I'm sure they'd reach terminal velocity really quickly with all that horsepower.

I think the problem with the R/C cars is gonna be tires holding together, and keeping them from becoming airborne... or keeping them from bottoming out and scraping the noses of the bodies due to downforce.

rc10gtisthebest · #19 06-28-2004, 02:39 PM

One thing I don't Like about how speed is going to be determined Length/Time stuff is because the car will still be accelerating through the speed trap. So if they enter at like 120mph and exit at like 170mph it will end up calculating to liek 155 or something.

My car reaches 70mph in less than 100 ft. But my car is VERY light.

mgs9 · #22 06-28-2004, 04:13 PM

At 150+ is it even possible to turn? There would be so much wind residance and alot of down force to keep the car on the track at that speed.

Vehicle speed will be measured by running the car through an electronic speed trap (likely to come from Race America), and you can use as much of the speedway as your radio range will allow to get up to speed.

If you would read the main thread, most of your questions would be answered. Or try using the search function.

As stated before, that's not an RC car. That's a tether car. Tether cars can get up to insane speeds yes, but all they do is go round in circles and can't be controlled at all. Has nothin to do with RC.

mab_man20 · #25 06-29-2004, 07:02 PM

Here is one thing that i dont get. Maybe im dense but an explination would be appreciated.

the current record is 111mph. Granted i think that was an average speed, why does everyone think that 200mph (almost DOUBLE the current record) is attainable? People are throwing around 150 mph like its no big deal.

Im curious to see how many people will break 100 mph, but im watching intently.
