Understanding the Impact of Rapid RPM Change on Torque

[Emre]

Hello,I've read somewhere that during launch rapid change of RPM causes an increase in torque?What is the point of this?İs that the reason why cars tend to make tires slip when we try to launch at very high RPM?The extra torque added to engine torque?

Yeah, me too. But I don't remember either where it was. Maybe in Reader's Digest at my dentist office? Or in People Magazine at my barber's waiting room? Let me try to remember.

Or, you could actually post a link to where you read this. Do you think that the quality of the replies you receive might actually depend on the quality of your question? Can you please try to post some more information to support your question, and help us to try to address your question? Thank you.

Look, sorry that I was a bit harsh in my reply. But it really is an important thing to try to post your question the best that you can in discussion forums. That helps others to help you, and gets you the best answers and tips for more reading and learning that you can do.

There have been some useful discussion threads here on the PF in the past about optimum use of the clutch in high-power vehicle launches (like at a drag strip), and other engine management tricks to maximize traction and minimize ETs at the dragstrip. So if you can post a couple links to your reading, and tell us what you have learned so far, that will help a lot in the replies you get. Thanks.
