I guess you can still do this safely when changing gear you let it go up before the change. This is not ok. You will burn the clutch if you race the engine before engaging the clutch. It is better to just drive the car hard intermittently for 5 minutes.
Ang redline kasi nitong D4D is about 4300RPM. Thank you for that important comment.
