He doesn't get it I'm not saying what op did is gonna kill his car but i know i have had my stock clutch slip in 4th gear from getting on it to early when the smart thing to do is down shift.

 

by putting load on the engine. your revs dont get higher when you brake boost

 

Yeah I'll admit I haven't really dealt with brake boosting very much...

But whatever, if the low torque you generate with a moving car generating low rolling resistance is enough to slip your clutch then you've got bigger problems.

 

How do you think auto turbo cars build boost from a dig when they break boost? Its not rpm its the load..

 

I suppose I really didn't give a flying ****... How do you like them apples?

Either way, exhaust gases drive a turbo...

 

To denlou-

If there is no load on the engine and airflow in and out are unrestricted, then all you have is a turbo spinning very fast. It's not actually creating much of any boost, if any at all. In neutral, hold your engine at a steady 6,000 rpm. Notice how you aren't making boost? That's because there's no real load for the turbo's compressor wheel to push against.

Do I really have to explain this to someone with 1,200 posts? LOL

-edit-

Also, as mentioned above- the car generates peak torque at around 2,000 rpm. How, in the grand scheme of this engine's capabilities does that constitute as LOW torque? That's the MAXIMUM torque the stock engine is going to create!

-edit 2-

Yep, exhaust gasses drive the turbo. You're right. If there's no load on the other side of the turbo, though, it isn't really accomplishing anything useful. At zero PSI boost and below, the turbo is just inhibiting exhaust flow. You should really remove yours for better performance.

Jesus I kinda fail. I see you're supercharged. At all rpm, your SC takes horsepower to drive. Just sayin'! I mean no disrespect to anyone here, all in good fun.

 

Gm made the car to only handle so much.. Its driver error though cause my stock clutch would only slip in high gear low rpms it never slipped taking off in the right gear. I'm not trying to argue with you just a lesson on turbo cars. Not claiming to know everything but i know enough not to ruin my car.

 

Ahh makes sense, glad somebody was actually able to explain that one instead of flaming me because they don't know either

 

I wasn't flaming you i told you load makes your turbo spool

 

Yeah you did, now I'm going to go crying to my girlfriend who is making me supper, which she'll totally wonder wtf is wrong with me and stop making me supper.... FML

 

No need to cry lol.. I learn on here everyday well not everyday lots of fucked up threads on here

 

haha yeah I wouldn't say everyday, this turbo thing was the most I've learnt in a while from here. Here's a list of things that CSS thinks are true that bother me and the topic of this thread just added to it.

Not in any particular order...

- Relays will keep your stock wiring system from burning out with HIDs
- Ecotecs "sweat" coolant
- Capacitors solve ALL electrical issues
- Clutches magically slip because there's no resistance to create torque

 

Did you>>>READ THIS?????



When a clutch starts to slip, the slippage will be most noticeable when the engine is under load, as when lugging at low speed in a high gear, when driving up a hill, when accelerating to pass another vehicle or when towing a trailer. The more the clutch slips, the hotter it gets and the more it wears. This accelerates the problem even more and may result in additional damage to the flywheel and pressure plate

 

Alright, we're back on track 1 again time to find another CD to play...

 

Its all good ronn we went over it

 

NEVERMIND

 

LOL^
WTF Is he even talking about.
Anyone else on here shaking their head at this?

No load @ 2000-2500 RPM in a HIGH GEAR!
BAHAHA
I'm not even gonna touch this one lol I'm seriously at a loss for words after reading all of that

 

i do it all the time lol, flooring it in fifth will reveal a weak clutch, but it wont do any damage to it, unless it starts slipping and you keep flooring it

 

who the f^ck cares!!!! its a new car its not a chevy citation with 300k miles on a stock clutch. Your not going to much damage and if you hurt the clutch its probable not from doing this, ITS FROM HOLES SHOTS AND HOLDING THE GAS TOO LONG WHEN SHIFTING!!!! if your tuned and doing this you might have a problem with the motor thats the risk you take. but if you are tuned, chances are that you are pushing too much power for the stock clutch to take. when the clutch fails cuz you suck at life we know that you'll replace it with a stage 17 clutch and will be pumped cuz you get to add a new sticker to your car to pretend like your some sponsored hot **** when really your a tool to society.

I have a '04 SC with 115,000+ miles on my car and do this daily cuz im a lazy f^ck. I have zero slip problems with my clutch. Its my DD and track ***** on the weekends. I also do this with both my staged '09 ss\tc and have no problems.

 

YEP...agree on that too. Just taking issue with those who say pulling under load in 5th at low RPMs doesn't promote slipping any more than flooring it in 3rd at same rpms.

 

DavidWAbout the Second or third true fact i've read on this thread yet!
YES there is an enormous load on the engine, clutch AND drivetrain in 5th @ 2000-2500 RPM.
Path of power will take the path of least resistance! and guess what, Your tires aren't going to break free @ 2000-2500 RPM, but under the right circumstances(already glazed/worn) your clutch will!
You're producing a large amount of torque at that RPM range in 5th because
A) That's the RPM range where a large portion of torque is developed with this engine,
B) RESISTANCE TO ROTATION IS HIGH.
TORQUE = RESISTANCE TO ROTATION. Denlou. Google it.
I went to school for it.
It's exactly like DavidW said, as long as you don't continue to do it while your clutch is slipping, it won't hurt anything. Yet it WILL reveal a weak clutch.

So no, flooring it in 5th will not cause your clutch to slip if there's nothing already wrong with it.

But to clarify, The power/torque generation in a low RPM range, while in a high gear, with a TURBOCHARGED or SUPERCHARGED engine, YES there is a substantial load on the engine because the resistance to rotation is high. =Torque

As far as turbchargers go, yes exhaust gases drive the turbine, but more importantly HEAT does. At LOW RPM and in a HIGH load situation, the exhaust is going to generate a HUGE amount of heat! Thus driving the turbine, spooling the turbo! and Ramming air into the intake with the compressor wheel. This is why a turbo will spool up EVEN at a low RPM under heavy load.

Hopefully that clears this up for some of you.

To OP

You're just fine No harm no fowl

 

I care! I payed for my car with my hard earned money and i'm not to lazy to down shift.. You can slam your car from 5th to 1st for all i care its not my car or my money to fix it. So you do what makes you happy!

 

Flooring at 2000 RPM in 5th:
A) That's the RPM range where a large portion of torque is developed with this engine,
B) RESISTANCE TO ROTATION IS HIGH.
TORQUE = RESISTANCE TO ROTATION

Take home points of this thread.

 

Once or.twice won't do any damage I used to do that in my Talon TSI when I had a few too many drinks and never had any major issue. I.shift 2nd to 4th a lot and no problems yet.

 

I never said slam.... shift nice, engage, then get one the gas. So long as your clutch is healthy enough to hold then you'll be alright
