I know it is a mismatch of speed or engine rpm, but can someone explain it more in detail what exactly causes the tire to chirp, and how to avoid it but still shift more smoothly and fast?

 

its called torque, live with it or shift slower

 

Or get heavier, stickier tires

 

its the tires losing traction because of the sudden acceleration. just like when you floor it from a stop, but a little less severe.

 

When your tires chirp its really not a bad thing, especially when you're racing. I guess ideally you dont want your tires to spin, but you're back into gear and going quick enough that you arent really going to hurt your run. Upgraded high grip tires may help with some of the chirp.

 

This has got to be the dumbest question I've seen on the org. Why does my engine get louder when I rev it up? Come on guy.

 

 

I believe it's called power. I could be wrong though. Anyone else have
any ideas? just playing with you man, but seriously...

 

So anyway, I noticed lately when I let go of the clutch, and apply gas my car starts to move. How is that so??

 

yeah aaaanyways, so earlier today, i spilled a little bit of pop in my cup holder and now its sticky? is it supposed to be sticky?

 

Play nice people. We all started somewhere right?

But Pimpshifus, it's due to the sudden torque when u shift. During shift (manual cars) the clutch disengages and the tranny is free for a moment, then u put in 2nd and drop the clutch. When u drop the cluth, the engine is spinning faster than the clutch so when the clutch grabs, it instantly spins up the tranny to the engine speed and therefore causing the chirp.... Basically the tires get a sudden burst of speed..............

I think my IQ just went down. This is a pretty stupid question bro. Figure it out man. Hope the above get u started.

 

dumbasss ... your not smart.

 

"you're not smart"

 

I really want to say something to those who posted offensive posts, but I wont cuz I have better things to do then take the time to post something just to call someone else a dumbass. I mean how much free time and how big of a loser is that??
anyways, I did some tests. I can eliminate the chirp when i shift into second gear if i get the engine rpm to 4000 to 5000rpms when i let go of the clutch. The chirp not only produces a chirping sound, but it also slows me down, like half to one second of rough acceleration......like wheel hops or something like that...... but it is hard to get the engine speed to exactly where i want it......
how do u guys shift? do u give gas before u let go of the clutch to get the engine running at the speed it would be running after u let go the clutch? or do u guys just release the clutch and then give gas.

 

What are ewe trying to say?

 

you dont have enough mods where you'd actually have bad wheel hop when shifting into 2nd. that might be a problem if you were pushing 320 FWHP but you're not. when you say "half a second" im sure in reality it is more like a tenth of a second (if that).

chirping the tries will not slow you down. while you dont want to the tires to lose traction, the fact that your tires chirped means that you are putting down the maximum amount of power to the ground. if you baby it and dont chirp the tires you are probably wasting precious potential power.

also, about what you are asking...are you talking about regular everyday shifting? or are you talking about race/power shifting? you should not be chirping the tires if you're just driving normally.

 

Actually, it is pretty close to half a second. The car was not smooth at all, like I can hear my dash area shakes. heck, i think it was just bad shifting on my part. the faster i shift, the more the dash shakes, and the longer the tires can't grip right. This is redline shifting btw, not normal driving. maybe it's our transmission or whatever, it is just not designed to handle that kind of rough shifting??

 

i think you're looking at tires chirping as a problem. its not a problem whatsoever. ive experienced heavy chirping (almost a mini tire roasting)going from 1st to 2nd, and sometimes a slight chirp going into 3rd. that is supposed to happen if you nail a shift. and it is probably more likely to happen in our cars because of the large amount of HP on a FWD car. if you're redline shifting and you're trying to go your fastest do not try to avoid the chirping. you will just slow yourself down. chirping is not a bad thing at all.

EDIT: when i say chirping is not bad, i mean it like bumping your head on the wall isnt bad. it is harmless just as long as you dont go overboard and do it a lot. the fact that you are chirping your tires means you are pushing your engine and transmission hard so it isnt a good thing. but its not something you should be worried about unless you do it alllllllll the time.

 

and do not hit the gas to get the rpm up before letting go of the clutch. Shift as fast as you can and get the clutch out as fast as you can, then get back on the gas as fast as you can, but you really shouldn't be touching the gas when the clutch is in unless you're in the mood for a new clutch/tranny.

Don't forget, even though it's fun to drive, it's not a race car. our transmissions are good for what they're designed to do. Shift it like you would a race car and in a month or two you'll be posting "why does our tranny suck so bad" and THEN you'll really get flamed.

 

Yeah bro, listen to 2k2wannabe and Newman, they're on the money!

Chirping tires will NOT slow you down by 0.5 second, and will probably not slow you down at all compared to taking it easier and not chirping. When you're racing, you want to shift the tranny as fast as possible and get back on the gas as fast as possible. As a result, if you do this fast enough and you're in the lower gears (1-3) you should experience chirping. Heck, I've chirped 1-2 and 2-3 (barely though) with 2 of my friends in the car.

Also, when you're shifting, foot off the gas, jab the clutch while moving the shifter into the next gate, clutch comes all the way out, and back on the gas. Sounds like a long procedure, but this is done in a fraction of a second once you practice it a little. Make sure you don't rev the engine while clutch is disengaged or slipping (this is known as powershifting) or else you'll be burning up your clutch extremely fast.

 

Thanks for the input guys! I didn't know it is bad for the transmission if I get the engine speed up (or to match the rpm of the next gear) before letting go of the clutch.... at least I couldn't hear any bad noises or feel any bad things happening when i do that..... But thanks for the tip.. i'll watch myself.

 

what you said you were doing didnt sound bad. what we were saying is bad is power shifting. power shifting is when you keep the gas floored as you press the clutch and shift gears. if you are simply blipping the throttle before you engage gears there is nothing wrong with that (other than making your shift slower)

 

Have you thought about trading for an automatic?

The only time you need to rev your engine to "match the rpm of the next gear" would be when you are downshifting, not upshifting. Watch your tachometer.
