Is stabbing the throttle bad?
 

Yesterday, I did a test on my car to see if I had the di failure. Which I don't. I first let the car warm up to 85c, and then I stab the throttle in while in neutral at a complete stop. I just stabbed the throttle to red line three times. Is this bad? I noticed the engine somewhat bogged for a second when I did this. Note, my car is turbocharged.

depends on the type of blade you used to stab it

I think the proper terminology would be "shanking the throttle".

I would assume its not great for it but it seems to still be running so I'd just carry on

The sharper the blade the better...

fucking beat me to it, prick. :respekt::bow::lol:

hmmm maybe just pricking the throttle will yield better results?

STV all trying to get the remaining likes after homeboy stole the first sarcastic post award :'(

hahaha nah im just really bored at work and have a sarcastic sense of humor

Serious answers for a serious question guys please

No, it's not bad for it unless you do it all the time or just sit there bouncing it off the rev limiter.

oh yeah stab the hell out of it, the more you stab it the better.

Thats the feel of turbo lag

Car think u didn't stab it hard enough, that why it was calling u a wimp. Stab it like u mean it.

As for other stuff........ why not just look at data log?

don't stab it too hard.. you'll damage your electronic throttle cable. it stretches out....

This screams retard post you seem to ask a lot of stupid questions in other posts involving your avo turboworld kit....

Hey, if a monkey were to bite ya, what kinda drugs would they make ya take?

What do you suppose they do with those little pieces of metal they punch out when they make a flute?

I think it's Carlton Blanchard!

Those remind me of Fermi questions lol

This is a place to ask questions. if you don't like it, why bother being in this thread?

I'm still learning about turbochargers since this is my first turbo. I like it, which is why I'm asking all these questions to make sure that everything is running properly.

No one took your question seriously because it wasn't descriptive enough.....

True, it is a place to ask questions, but the funny ones get the most love. OP, this is not the place to ask this kind of question. It belongs in the General forum. Ask yourself "How does throttle technique belong in the Maintenance subforum?"

From the manual -

Warning: Constant stabbing of your car in an enclosed area can result in death from carbon monoxide poisoning. Always stab your car in a well ventilated environment.

-_- you're right. At least I know now. I did get a kick out of the jokes tho. Thanks

Turbo Lag vs. Throttle Response
 

Hi Guys,




Astroboy, in the spirit of learning, here's a few things to remember about turbos. I'll try to explain these points as they link to throttle response and lag.


- The lower engine rpm is, the slower the turbo spins because of low exhaust gas volume.
- The bigger the turbo is in relation to the engine, the more exhaust gas volume required to spin the turbo.
- The slower a turbo spins, the less intake air it forces to the engine.
- The less intake air you have forced into the motor, the richer the air/fuel mixture will be, and too rich creates diminished power.


Now, throttle response and turbo lag are two different symptoms.


-Turbo lag is built into the nature of basic turbos, and can be expected in most applications. Small turbos will build pressure quicker (spool), but reach maximum volume (boost) quicker, and large turbos will take longer to build pressure, but have a higher maximum volume. Be sure you have the appropriate size turbo for your engine volume/rpm range and application (I.E. drag racing, road racing, etc.) and make sure that your tune is optimized for the same. You can also eliminate lag with variable vein turbos and tuned fuel loading, but that's info for a different discussion.
-Throttle response is a similar principle to turbo lag, but with engine tune. When you "stab the throttle" you are trying to feed the motor air and fuel. The engine needs to receive air and fuel at the same time, in the right ratio, to produce power and response. If you receive too much of one or the other, it makes the engine hesitate, bog, or sometimes just die. It's common for turbo cars to have bigger injectors, or have injectors tuned to produce more fuel volume to fully utilize the boost pressure of a turbo at high rpm. At low rpm, these injectors can be a bit over active and produce too much fuel for a short time, exaggerating the beginning of your turbo lag.





As far as your particular hesitation, if you only notice it at idle, and it's not present at even slightly higher rpm, or while at a rolling speed or normal driving, I wouldn't worry too much about it. If it's a significant dip in rpm and almost dies, if it bogs for a long period (longer than one full second), or sounds like the engine is almost struggling to produce power, I would advise you to make sure you're running the proper fuel, make sure your intake is clean/clear and free of boost/vacuum leaks, then have the car's tune updated.

Hope this helps answer some of your questions, and unveil a little of the mystery behind turbos.
