Can't drop the clutch or rpm's will just drop

[Deadly BlaZe]

Ok here's the thing, when I try to launch my car, if I try to drop the clutch, the rpm's just drop back down. I have to slip the clutch out if I want to launch at all.

Also when trying to just get going from a stop, I have to slip the clutch for pretty long if I want the car to get going smoothly with out the rpm's just dropping suddenly.

Any ideas of why it does this? It's a stock clutch btw.

Do you smell any burning? Clutch going possibly.

sounds like it might be slipping.

You should never "drop" the clutch. Unless you'd like to replace a clutch, tranny, or other various drivetrain parts. Slip it a little bit.

I'd expect, since it sounds like you are new to this, you are off the throttle/at part throttle when the clutch engages. Try slipping it, and when it starts to bite, you have to anticipate by adding more throttle. The clutch engaging is going to pull the revs down, you have to counter with more throttle. By the time the clutch is grabbing all the way you should be close to WOT. This all happens in a fraction of a second, but timing it right or wrong is the difference between a bogged launch or a melted clutch and a 1.7 second 60 ft.

What rpm are you launching from?

Define: "pretty long"

If you are on a level surface, can you be gentle with the clutch and get the car moving with ZERO throttle?

With a slipping clutch revs would climb excessively, not the other way around. Unless he is wording it wrong, he's making it sound like his clutch is biting TOO much.

Ok I'll try to describe this a little better

In my 5 speed Hyundai, I could rev to 4k, feel the clutch catch and just drop it quickly and it'll spin the wheels and the rpm's will start climbing and not just suddenly drop like my talon.

In my talon, if I rev to 4k, get the car moving a little bit and then drop the clutch, it'll just stutter and drop rpm's. I have to hold the clutch in the middle for it to keep the rpm stable with out dropping it too quick.

Even when I'm not trying to launch and just get the car moving from a stop, I have to slip out the clutch for a few seconds until i can completely let it go. If I let the clutch go too quickly, the car will stutter and drop rpm's.

Define: "pretty long"

about 2-3 seconds

I would think with any car if you did this, it would just stall correct? Assuming you're talking about from a complete stop, mine would do that. The surface would have to be inclined just a tad for me to get it going with 0 throttle from a complete stop.

Its because you're an "overly aggresive driver that doesn't use his full brain power to think things through before doing them" (translate that into whatever you want) and you shouldn't be dumping the clutch at 4k. Of course the RPMs drop, that thing doesn't have the power to break 4 tires loose. Its called a BOG. Don't dump the clutch, end of problem.

Thanks for the advice but the idiot part is uncalled for and you need to grow up. I can do whatever I want with my car. I've never really launched an awd so I wouldn't know much. Besides, I asked for advice, not criticism. In the real world (not the interweb), you don't just go up to a person who would ask this kind of question and call them an idiot up front without knowing any details about the situation.

Anyway, assuming you're right about launching, what about just getting the car moving from a stop, If i release the clutch too early (at about 2k), the car will just stutter and drop rpm's. In every 5 speed that i've driven, I've never had to slip the clutch for such a long time to get the car moving with out stuttering.

Sounds like it's just timing. You can let the clutch out pretty quickly but you have to keep on the throttle. Like I said, the difference between bogging and launching is very small. Practice makes perfect, good luck!

BTW, it sounds like you weren't exactly on with the Hyundai either, wheelspin isn't really a good thing. Although you were a little overbearing with the gas on that car, and now it sounds like you are being a little too light with it on the Talon.

Well the reason I mentioned the Hyundai is because when I dropped the clutch, all the power went into the wheels quickly. With the talon, it just stutters. Maybe it's just because it's awd but then again it was doing the same thing when my rear axles were disconnected. Who knows. And the only reason I was such an asshole to that Hyundai was because it was a temporary, free junkyard car.

LAWL.

But seriously Tyler is right, this ain't no Hyundai. Find the sweet spot and you won't bog. Drop the clutch a few more times and you'll be hearing clunking that only goes away when you open your wallet.

To be entirely honest with you, that IS how I am in the real world. I tell it like it is and I am an asshole to people I think are stupid. I normally tone it down for this forum. Doing 4k clutch dumps when you admit yourself that you don't know to launch an AWD makes you an idiot. And I don't want to hear anyone chastise me for it because I've seen mods being even bigger assholes.

Back to your question.

Your 90whp Hyundai doesn't have a very strong clutch. You could probably dump it from idle and the car would start rolling. You now have a higher powered, much heavier car that needs you to give it some gas and clutch slip to get it rolling. What you're discribing sounds perfectly normal. My driving style on this car usually uses very little clutch slip and very little gas. I start the call rolling on the verge of stalling. Its just how I drive. I don't like to slip the clutch excessively. If that's just how you drive, don't worry about. It does require a long clutch drag to get these heavy AWD cars rolling smoothly.

You could've just said that in the beginning. Anyway, I only did the 4k clutch drop 1 time before I realized it wasn't right. So it's not like I did it repeatedly like a moron. So anyway, I'm assuming it's ok to slip the clutch out a little bit longer to get the car moving from a stop so that it doesn't bog or stutter?

 

[MyBeatGSX]

Yes its fine, its just how the cars are. Give it awhile and you'll get used to it. Or go test drive some new cars, they'll feel the same.
