top speeds...
what are the top speeds of the inferno's, hyper buggies? can these puppies go 50mph w/o many mods?
obv. it depends on the engine, so specify the engine i guess. |
RE: top speeds...
whats your intent?
50mph is possible with a 15/48 cb/spur combo and a good engine, but it would be rather slow off the line. |
RE: top speeds...
Bone stock, with RTR components, you can expect 32-40mph from the Hyper 7 buggies.
You can of course find a smaller spur gear and a larger clutch bell to go faster, but that may well overtax the engine. The other option is to buy a kit, and get a big block .26 or .28, even a .30 engine, if all you want is speed. Buggies are heavy. Very heavy. It takes alot of power to get them going, and even more to keep them there. 50mph is about max for a single speed transmission 1/8 scale. I've seen it done with a .30 engine and 35% nitro. But the engine lasted only 4 tanks before blowing the connecting rod. |

Or the rbs c5,c6 ws72,ws73. For pure speed.

You just can't overgear it otherwise you will lose top speed and either way your acceleration is going to be slow. Edit: The mayhem is the only RTR 1/8 buggy (that I know of) to have a proven recorded speed of 50mph stock. |
RE: top speeds...
Super_Dave,what do you mean by geared higher?
|
RE: top speeds...
You can get a higher gear ratio, by putting on a clutch bell with more teeth, or a spur gear with less. This results in a higher top speed, but slower acceleration. Same as changing gears on a bike. Think of the crank gear as the clutch bell and the rear wheel gear as the spur.

RE: top speeds...
yeah, but if you got more torque the engine pulls more, then you can put bigger cluthbell and smaller spurgear on it. Because the engine got so much torque, also you could just buy a P5 or WS7 X3, but obviusly, thats only if you are going to race ;)

RE: top speeds...
Although the larger engines, such as the .26 and .30, are fun in a buggy because of all of the torque; there are better ways to attain speed and responsiveness. I say this from experience. I've gone through almost a dozen different engines and didn't get what I wanted, in terms of speed and responsiveness, until I went with a hot .21. I'm running a Collari XS380 and it runs better than any of the larger engines that I tried, including the VG30. It is much more responsive on the track, clearing doubles and triples with little effort, and the top end that I was looking for is there now.
With the way that technology has advanced, the old rule of there being "no replacement for displacement" no longer holds true. Well, it's not an absolute anyway. If you want to be quick and go fast, go with a nice .21. Even the Hyper .21 8 port pro runs pretty good. |
RE: top speeds...
I got a REX-X which does 40mph easy and on tarmack with no mods i can get it up to about 45mph.

RE: top speeds...
My friend races his truck at maryland international raceway which has a 132' track for RC cars also. His truck traps between 48-52 depending on conditions. I just beat him pretty good with my new Ofna violator which has a .28 on it. I am going to assume its a picco .28 and my buggy is bone stock for now.

Aangelet there are some great big displacement engines out there but you can't feel it in a buggy unless your bashing in grass, mud, or sand. These buggies are so light they would just blow the tires off before anything so you wont even notice how much torque it really has untill you put it into a truck. Not to mention theres pleanty of .21s that will blow the tires off of these buggies. Yes, you can gear a big displacement engine higher as well but its not going to make up for 5,000-10,000 RPMs. |

RE: top speeds...
if your only interested in speed get a road car, buggy's are for acceleration and good handling, and i would say most RTR only would reach 30MPH!.

He has it lowered and has a custom made wheelie bar to keep the front down low. His truck carries the front tires from start to finish and they dont touch back down till he lets off the throttle. The first couple times he went there to race they laughed at him. His truck is so ugly that I myself wouldnt be caught dead driveing it. But I give it and him credit. It is FAST and unless there timing system is wrong (which i know it isnt) then his truck runs 48-52 and I beat him so I duont know what you want me to tell you. All I know is that my violator beats his truck in 132' drag race by about 2 cars. |
