1/4 mile times
 

ok on a 20foot 7in track me and my friend were doin single runs yesterday and came up with some interesting data.

20ft7in = 1/4 mile divided by 64

my friends zipzap stock zip with the 21.5 motor and red gear was doing anywhere between 6.5 seconds and 5.5 seconds on a linoleum floor.

my clone with the k.i.t. racer orange motor and red zz gear was easily doing 5.2. given that orange motor doesnt fit my motor well very good either.

so i am curious to know what people with 3.8 motors are doing.

so everyone is into paintjobs and neat wheels but nobody actually measures the speed of these things?

i dont really record time i record my wins thats all that counts to me and looks of course yeah and i got a 3.8

hey my friend and i did that this weekend and my 2 speed ran like 4.85 with nos motor. the 2 speed really unlocks its true power

I just picked up a "RallyRacer" from a gas station on my way back from Las Vegas last night and I put in my DKS 3.4 motor and the blue BCG gears. I ran the 1/4 mile in 4.078 No dual battery mod, no other mods except the DKS engine and the gears. The car is SCARY fast. If I don't put the LXX medium tires on it then it flips over everytime I turn. I don't even dare to try a 3.8 motor.

If I could just get the wheelie bar to fit, then I'll be in business.

I know this thread isn't up to date but.
I ran 2 cars on 10ft lenth though. Not enough space for 20ft.
I ran 2.70 seconds with red zz gears and a 2.6 motor
then I ran my crappy car that I run on baby powder with stock rims and a 2.2 motor: 2.80
I ran both of them a couple of times and came up with these averages.
both cars are microsizers

20 ft?!
 

geeze twenty feet ?! dang, i can barely get 15 feet w/o fliping, spining out or running into sumthing ! haha, but i guess ill try, would it be the same if just mulitply my 10' time by 2 ?:rolleyes:

not really. that wouldnt be a fair comparison. that would be like saying in a running race you dont need to do the 800meter race because you could just multiply 100meter sprint scores by 8.

your car isnt up to full speed at 10foot.

I ran my 3 cell Zip Zap on the 20 foot track and came up with somewhere aroung 3.5. It's a bit too fast. I ran it on an $18,000 treadmill at the hospital, and it ran 7.5 mph.

Hmmm, those numbers don't equate chelboed.

20 feet in 3.5 seconds comes out to 3.89 mph (249.35 Scale mph)

7.5 mph = 480 Scale mph

what gears were you using?

I'm using the ZZ low gears. I didn't use a stop watch, I will try again and make sure about my times. The top speed on the treadmill was accurate, though.

Oh, by the way... 20 feet is not scale 1/4 mile. It's just what Bit Char-g decide to use. actual 1/70 scale 1/4 mile is 18.9 feet. Who really cares, anyway. Close enough.

Okay, here's what happened. I had my potentiometer turned down a little bit when I tested it for the 1/4 mile. I just kicked it up to full throttle, and ran downstairs (at work) to test it. It's pretty slick down there, so I couldn't get a straight 1/4 mile w/o spinning out. I had to do 12 feet which was about 1 second. I'm assuming the last half of my quarter would be less than that because my momentum is already going. I'm going to try to put another potentiometer on my steering so I can turn it down for dragracing to control it better.

With blue ZZ gears (power), I turned my potentiometer to the minimum and got 4 seconds in a 20 foot quarter. Potent. half way, I got 3.2 seconds. Pot. 3/4, I got 2.5 seconds. All the way, it was too slick, but I did the 12 foot in 1 second.

my friend wants to build a quarter mile strip out of hotwheels track. it will have optical sensors hooked up to a timer. it will time 1/16th mile and 1/4mile times.

Do you mean "1/8" and 1/4?

I just put the red ZZ gears in my 3 cell F&F Zap. It is a little slower off the line, but I can at least do the entire quarter on a tile floor w/o spinning out. I am running the 20 foot in abot 2.3-2.4 seconds with my potentiometer cranked up. (i think it's getting about 8 mph, but I'll check on the treadmill this afternoon).

Correction: I just checked it this pm, and I'm getting 7.8 mph.

Hey, Hot Wheels track ya say? Do you mean with the side rails and stuff so you don't have to keep the car straight? I could go WICKED FAST on one of those!

ya. that would be a true test of power.

Dude! I found some new tires that stick really well. They look like Bit smooth tires, only like a mm or so thicker, and a 1/4 mm wider(they are flush with the outside of the rims). They came on a clone. The footprint is VERY flat which means more rubber on the ground. Before a run on the floor in the basement at work (slick), I lick my fingers and wipe the tires off. This makes 'em tacky.

My new (21 foot) 1/4 mile times are as follows for my 3cell zip zap:

I use 3 standard cells, Red ZZ gearset, clone rear tires, and a clone motor that "resembles" a Tomy 2.6 from th rear and a ZZ from the front and side. (weird)

Anyway, my time for 22 feet was 2.2-2.3 seconds with the body on, and 1.7-1.9 with the body off. This thing is sooo much faster with the body off, I'm going to try to shed a few on the chassis, and body some how, and see what I can do.

got any vids?

Yeah, totally! But It takes me like 15 minutes to upload one onto geocities. I'm trying to build a site. I am on dial up. I wish I had cable. I don't have vid's of the simulated 1/4 mile because I don't have even 10' at home to work with. I have been doing these at work. Soon I'll bring my video cam to work and tape a 1/4 or two. I have about 3' of runway at home, but I have been video'ing my jumping.
I have never built a site before. It's been a challenge. If you use the "wizard", you have to do like flowers or stars and stripes. I just want to share my videos, man!

get dreamweaver or something. www.download.com has several programs.

Hey pigman, I filmed 3 simulated 1/4 mile runs today using my blue ZZ gearset, and got 2.0 sec, 2.3 sec., and 1.9 seconds. With these new clone drag slicks, I have never seen it so fast. I don't have time to dink around with a website right now, can I email them to you to post for me?

By the way if anyone does get to view the vids, the time stops when the car hits the wall (OUCH!!!!). That's 20'7''.

...tried this last nite avrg.time was 7.9-8.2 no dual cell but i dont have 3.8 gotbrspec ....
