Forge Dual Piston Ram Dump Valve Cavalier Turbo
R.R.P.
£94.99
Only:
£75.99
Suitable for most turbo cars with an Air Flow Meter on the Cavalier Turbo.
Made from billet aluminium, this atmospheric diverter valve dumps the charge-air to atmosphere creating the "Whoosh" sound when the throttle is lifted.
Unlike single piston or diaphragm diverter valves, this uses counter balanced springs and dual pistons to prevent the valve from leaking air into the intake system at idle. This prevents our diverter valves suffering any of the failures associated with single piston and diaphragm type diverter valves.
Available in machined alloy or black finish.

The above figures are estimates only and should only be considered as a guideline
Please note
- fitting a stronger spring into a valve will not increase boost pressure unless existing pressure is being lost. Failure to allow the valve to operate by installing a spring which is to strong may cause damage to the turbocharger.
The red coded springs should not be installed in the DVR or DV007 diaphragm valves
