It'll be louder if you wind the boost up, but remember you're not flowing nearly as much air as in a petrol, and you dont ever have that point where the throttle plate shuts and the air has nowhere else to go but out of the dump valve. With a diesel, if you come off the throttle, the engine is still drawing in air, so there isn't any massive quantity to vent or any massive pressure to vent either...Yeah a 2l turbo diesel engine at 14psi flows nowhere near as much air as a 2l petrol engine at 14psi
Dump valves work fine on standard petrol cars with tiny engines and 5psi of boost so as long as you can get it to open fast enough you will make a good noise
