Advanced Revving Techniques
Once you have mastered the basics of revving your engine, you can start to experiment with more advanced techniques.
Blipping the Throttle
Blip the throttle to quickly increase and then decrease the engine speed. This can be used to match the engine speed to the transmission when downshifting, or to clear a flooded carburetor.
Rev Matching
Rev matching is the process of matching the engine speed to the road speed when downshifting. This helps to reduce driveline shock and make for smoother downshifts.
Heel-and-Toe Shifting
Heel-and-toe shifting is a technique that allows you to blip the throttle and downshift at the same time. This is a difficult technique to master, but it can be very effective for performance driving.
Double Clutching
Double clutching is a technique that can be used to downshift smoothly without rev matching. This is done by first putting the transmission into neutral, then releasing the clutch and blipping the throttle, and then re-engaging the clutch and downshifting.
Power Shifting
Power shifting is a technique that allows you to upshift without lifting off the throttle. This can be done by quickly releasing the clutch and then re-engaging it at a higher RPM.
Flat Shifting
Flat shifting is a technique that allows you to upshift without using the clutch at all. This is done by quickly releasing the throttle and then re-engaging it at a higher RPM.
Launch Control
Launch control is a system that helps you to get the best possible start from a standing position. This system is typically found on high-performance cars, and it can help you to achieve maximum acceleration.
Table: Summary of Advanced Revving Techniques
| Technique | Description | Benefits |
|---|---|---|
| Blipping the Throttle | Quickly increase and then decrease the engine speed | Match engine speed to transmission when downshifting, clear flooded carburetor |
| Rev Matching | Match engine speed to road speed when downshifting | Reduce driveline shock, smoother downshifts |
| Heel-and-Toe Shifting | Blip the throttle and downshift at the same time | Very effective for performance driving |
| Double Clutching | Downshift smoothly without rev matching | Less driveline shock than heel-and-toe shifting |
| Power Shifting | Upshift without lifting off the throttle | Maximum acceleration |
