When I shift quickly, very quickly the power gives out... it's like I'm hitting the rev limiter but I'm not. The power is just not there after I release the clutch, RPM's go down to like 2. The clutch is strong though, it holds on steep hills, doesn't slip, and launches fine. Cars only a couple of monthes old.

 

LOL. So many people complaining about the RPMs sticking around after depressing the clutch, and you think it's too fast.

 

what do you mean by RPM's go down to 2K? After the clutch is engaged the tach reads 2K?

 

I am very confused by this thread

 

maybe your not shifting fast enough lol. when i shift at or around redline the rpms hit 4000-4200 when i place it in the next gear. i guess it takes more than mods to make someone drive better?

 

This isn't my first rodeo. I've had my share of performance cars. Plus I've had three 9 second bikes. Listen people, I have it floored I shift around 6, so that means I fully depress the clutch let off the gas and move the little stick to second gear then release the clutch and floor the gas pedal. Instead of the car keeping up momentim in the power band, the power just seems to give out. So when I shift into second instead of the RPM's being up over 3 they drop to 2 it feels like the car stops burning fuel it's weird.
I guess I'm the only one with this problem?

Bad/Inexperienced driver? I road raced at Lot 60 at UW Madison for two years. With several different cars and a UW "race" go cart built by a group of mechanical engineer students, 3 of which are my friends.

 

i think all of the 07's have this problem

 

Ok, i'm not being a d**k but I think you're the only one with this. I've also had my share of manuals and this one has given me the most problems to learn with. I'm good now though.

Your lightweight crank pulley does not remove enough rotational mass from the crank to make it a factor. I have it and it's only about a 200-300 rpm difference in rise and fall.

Is it stock? If you have a lightweight flywheel, you're RPMs will drop quite fast, but they should never drop that fast if you're at redline (6500). If they do, then the timing in your shifting is off or you have the lightweight flywheel. There's no other explanation for it. The stock rotational mass of our flywheel is quite heavy and keeps our RPMs up for quite some time between shifts. That's why they marketed this for the "young" driver; it's supposed to be easy to shift. You might want to try this:

Instead of depressing the clutch flat to the floor, try only letting it go about 3 inches or about 1/2 way. Then punch the next gear and let off the clutch and give it gas. I've been able to speed my shifting (i also have a short shifter) using this technique.

If you still notice a problem and your RPMs are dropping very quickly and you don't have a lightweight flywheel and you're using this new shifting technique, take it to the dealer b/c you might have something wrong with the drive by wire system. B/c there is no IAC valve and it's all controlled in the throttle body by the ECU, it could have some malfunction or improper reading. Hope this helps.

 

Are you sure, I haven't heard of this before...I have an 07 but i still haven't gotten on it yet (not broken in). I will look for this though when I do get on it for the first time.

 

I have a 07 and don't have this problem. I shift around 6k rpms and it drops a couple of grand but NOT down to 2k rpms.

The only thing i notice is that their isn't much power when shifting to the next gear. I know what you mean by when you say it doesn't keep pulling hard....but thats just because the car is SLOW.

Sux about your bike!

 

I've noticed some power hiccups after shifts on my 07. I didn't really think too much about it, and mine doesn't sound as sever as his problem, but its definitly something to look into or try to remedy. I'm thinking the Fidanza flywheel might be the cure for this.

 

Bad/Inexperienced driver maybe? I heard they made this thing called a automatic for people like you.

oh god. It's not even suppose to do it when it's stock... so why a remedy? no reason for a new flywheel. you bought a 17,000 dollar car for a reason.if you're gonna sit here and _____... just go get a new car. or here's a good idea. take it to the dealership. simple as that... it's a warranty issue if anything... or just take it to cryspace... and just get sad about it.

 

^^Agree. Just take it to the dealership as much as possible if it's under warranty. If you haven't put any mods on it, then that's the best cure, not a mod.

 

Whoa! Calm down ladys! I wasn't really complaining, I was just telling the guy that I had a similar problem. And I'm in no way an inexperienced driver, I've had manual cars for 11 years and my last car was a turbo'd civic with a stage 3 race clutch so I'm pretty sure I know how to shift. Anywho, I'm just not a big fan of how the revs stick around so long so thats why I'm thinking of going with the Fidanza wheel.

 

How's this for an idea.

You all notice that if you shift really quickly, as you release the gas and immediately hit the clutch, the RPM climbs for a little bit right?

Maybe he's shifting that way right at redline. If he's doing that, then the fuel cut off will engage to try to keep RPM away from redline. That would definitely explain it feeling "like hitting the rev limiter." So even without hitting the limiter before shifting, he may be hitting it by hitting the clutch too soon.

 

^^ I dont think thats possible going by what the original poster said (shifting at 6K) b/c 07 limiter doesnt come into play until after 6500RPM.
I agree with Scionizer07. I enjoy the tC but I also think a lighter flywheel would help the driving experience tremendously......... but thats a matter of preference though.

 

HAHA, I somewhat agree, except for the part that its ONLY a 17k car! Thats more than a lot of new comparable cars today.

For 17k your car should drive the way you want it to, and if it doesn't, then try a different car like chris said. Not trying to be a d1ck, just my opinion

 

to the original poster, not doubting your driving abilities but are you by chance missing second and hitting fourth?

 

I've noticed this happen on my 07.... It only happens, however, when I shift too close to the rev limiter and it *will* hit the rev limiter because of the damn rpm flare when depressing the clutch and letting off the gas. Nothing that some simple foot work and timing won't fix. I have no problem with it now that I've gotten used to the car...

 

No, I'll have to disagree here - it doesn't go up. It only sounds like it is doing so. I used to think it climbed as well, until one day I decided to stare at the tach and see what was going on. The RPMs just stick at the exact level that you clutched in at.

If they're going up, then you're probably staying on the throttle a split second too long
