A non-recirculating d.v. vets the boost pressure to atmosphere with the "ptsccchhhh!" noise.

I think it more for the quietness, you can get a twin piston non-circulating one that works with airflow meters. On 7th Nov, 2008 Nic said:

If you just dump to atmosphere, the car will run rich because not all of the air it has metered will make it into the cylinders. 61 Austin Seven; building a 1275 'over the clutch' turbo, R5 T2'd, custom intercooled, megajolt electrified, canyon carver

(on an injection car anyways?) open to criticism, but just my idea:) |

You are always getting enough fuel to at least idle the motor. 61 Austin Seven; building a 1275 'over the clutch' turbo, R5 T2'd, custom intercooled, megajolt electrified, canyon carver
