Dump Valve Question

(1/3) > >>

petergalileo:
Ok, the kids thinking their dad needs to be a bit cooler got hold of a dump valve.  They think the woosh is cool ? anyway, they bought one for a petrol motor but I just realised theres no vacuum really on the intake side of a diesel.  

I know a little about the turbo system on the 300 and it already has a wastegate, so is there anyway of fitting this dump valve and will it affect the motors performance or just make it sound like a lorry ?

M19 ROO:
the (petrol) dump valve will never work no matter what you try

and if you really have to have one they cost around 200-300quid for a diesal dumpvalve and at that price there really aint no point,

petergalileo:
ouch ! I will get a big bottle of lemonade and a loudhaler in that case.  Thanks

petergalileo:
Ouch again !

What about modifying the wastegate ? where does the air from that go or is it different to a dump valve ?
