That was what i was thinking. I know that it may seem like a waste of money but a close friend of mine has the same set up running pretty much the same boost (a fair bit more than standard) and his turbo has just blown to bits. The company that rebuilt it has asked him did he have a DV or blanked it off? He had blanked it off and they said that would have help to the breaking of the turbo unit?
So to spend £80 on a dump valve to make me save £100's on a new turbo?
Thanks for all the advice though chaps
They are talking complete bollocks mate. Providing the turbo was a fairly normal Garrat, not T4 or larger or running 30psi of boost. This has been discussed on this very forum time and time again. Or was your mate trying to chuck a shed load of boost through an old standard turbo?
You do not need one, there is no benefit to having one recirculating or otherwise.
If you still want to go ahead and fit one of any type go ahead just don't be fooled into thinking it will offer any additional protection. In some cases it can cause the turbo to overspeed which is potentially damaging.
