Default avg speed of 1/8 buggy?

Just wondering what type of speed should be considered normal for a 1/8 scale buggy with a .21 engine. I'm interested in knowing what kind of speeds you guys are seeing at the track. I know they won't be doing anywhere near what on road cars get, but I'm interested none the less.

for racing applications you will be at a top speed of 35-40MPH but you will very rarely use it. You can gear it up to get closer to 55MPH but that would be useless for racing

Sounds about right to me....

Nothing is too fast for me. Nobody said I had to bring everything back in one piece did they?

35-40mph is still faster than I thought though, not bad at all.

Depends on the track. Our track here.. new track in ny
... on sunday were averaging about 14 mph according to the amb, for a 9 lap round, around 35 second lap was the fastest. Lots of on/off throttle through the track.

I think thats what Jaz was saying. We only hit that 35+ maybe for 2-3 seconds depending on the size of the track.

I remember reading some articles in an RC mag where they used a radar gun to get top speeds on 1/8th buggies and they were in the 40-45mph range.

Straight line speed is not really of much interest, a race is seldom won on the straight. It is the corner and the rough section that counts.

On a race track, 35MPH is fast and is reached only few seconds. IMO faster accelerations are more important than top speed.

You can gear up to reach 50+MPH easily but it is worthless, except if you wish to beat the longest jump record!

There are allot of variables. Clutch, engine, fuel, plug and gearing will all play a part in top speed. IMO races are won and lost with torque (bottom end) and really have nothing to do with how fast the car is. Even if you have a buggy that can blow past everything on the track on a long straight away it just means you will be braking that much sooner at the end of the straight. By the time you come out of your turn pretty much every car on the track will be even with you in the hands of the right driver ( not me ) having a ballistic top speed is absolutely useless during racing applications because in order to get that top speed you have no choice but to sacrifice low end torque which means you will be rolling jumps or casing them because your car don't have the power to clear them without 30 feet of run up. Playing in the street or at the park is fun for about 10 minutes going 60MPH but it gets boring really fast

I saw a guy a couple years ago that won a 30 min main and rolled every jump he never made a double and just put putted around the track. Everyone else was crashing and he just went right buy. He never crashed and I bet he never broke 15-20mph. I don't think I could do it I gotta fly in the air bit if I didn't see it I would not have believed it.
