Why do we continually confuse a slight hesitation on corner exit with a carburettor problem.
How many times have you "chased your tail" making unnecessary changes with no performance improvement. Most of the time it's down to the driver as he/she brakes for a corner.
Braking too early and/or approaching the corner incorrectly will cause the pressure in the tuned exhaust system to drop off causing the PV to close. (Assuming it's a Senior Max.) Ideally the PV should operate @ 7500 RPM, the adjustment allowing +/- 300 RPM changes to be made.
This may result is a slight delay or hesitation when throttle is applied again. This delay is due to the pressure having to be re-established once again in the tuned exhaust system until it is sufficient to re‐open the PV.
Another reason for potential lag is driver throttle application. Many drivers tend to "floor" the throttle at the exit of a corner which is not the correct technique. The best method is to ease the throttle on from the exit of the corner.
