Is it possible to do burnouts w/ a 4wd nitro car?

ChevyRidinLow · 01-07-2007, 09:30 AM

i kno this may sound stupid but is there any way i can do burnouts w/ a 4wd nitro car? the on-road tires from my old enzo nitro car that my brother totaled fit onto my new buggy...and i thought it would be cool if i could do a burnout or somethin since i have no use for them.

if you don't want a motor very long you can.

Nitros need air to cool down, high rpm with air blowing on the head is fine, high RPM not moving is not.

What do you mean? My RS4 does burnouts every time I mash the throttle from a dead stop. It is ridiculous, I get hardly no traction whatsoever at all, whether it is dry or wet. Wet conditions are especially fun.

i'm thinkin he means standing burnouts. My RS4 does the same as yours.

yeah thanx i was talkin bout standin burnouts

Oh, I see. Wouldn't it be a little difficult to do a real burnout with an r/c car? Considering you have to mash the throttle in addition to somehow holding the brake. When you figure this one out let me know, and no cheating by putting something to hold the car in place!

yeah that's wat i was thinkin just holdin the car in place. i saw a pic on the internet somewhere of a guy w/ his foot in front of the car while the tires were smokin

That must have been crazy.

ChevyRidinLow · 01-13-2007, 05:53 PM

oh i just got an idea...wat if i used my dad's air compressor and blew air on the engine while doin the burnout??

pre98zetec · 01-13-2007, 06:17 PM

that could work, but why? why waste your tires

ChevyRidinLow · 01-15-2007, 10:56 AM

oh i just had the old tires from my old rc car and didnt have a use for them. altho right now my priority is trying to get the new rc car adjusted...everything i do to try and get the idle right seems to make it worse

uuhhh(im a novice to this so please bare with me)

I was in the process of adjusting the idle speed...and i tell ya i had it AALLMOST perfect. so i backed out the screw another 1/8 turn. when i started the engine again...the idle speed for some reason seemed to jump way up...as if i was trying to increase the idle speed. but i wasnt. i backed out the screw again another 1/8 turn, started it, and the same thing happened. after this i put everything back in the garage to let the engine cool...since i was still breaking in the engine.

if it means anything, i had the car on the ground. the car just vibrates off of a brick...and i tried c-clamping it to the frame of my dad's utility trailer(like i did with my old one) but there wasnt enough room for the c-clamp w/ out blocking the steering servos.

I went to the local hobby shop and the mechanic there said that on a cold day i need to 'fatten' out the air/fuel ratio. so like i was instructed i backed out the screw 1/8-1/4 turns and at first it seemed to work but then it didnt. also, everytime i apply the brakes the engine stalls out.

adjusting idle speed should never be messed with.

If the car runs, and doesn't die... leave it

He's talking about riching it up, in a sense you should as the air is more dense.

Look around your car, see where the fuel line enters the carb? there's a needle there. That's the needle you should be touching. this is called the High Speed needle (or HSN) it adjust the fuel ratio when in the higher RPM's. But, i remember you saying you're just out of break in.. The cars still rich and fine to run that way in cold weather. Personally I don't change tune for temp. I only change tune if it sounds out of tune. If it sounds rich, i lean it, if it sounds lean.. i richin it.

Put your idle back where it was, leave that alone. Don't touch it. That doesn't effect the tune or fuel to air ratio, it simply adjusts what RPM you want the engine to idle at. Adjust it so that the car stays running while breaking but also adjust it so that the wheel don't move when the car is lifted up.

hope i helped
