Josh Posted June 23, 2018 Share Posted June 23, 2018 Hi all, Today I went for a drive in the Supra and noticed when I let off to change to third, I heard compressor surge. This has never happened before today and it does it every time I let off the accelerator whilst the boost gauge shows positive boost. I've just got the stock BOV fitted, so I'm assuming it has failed. If anyone could tell me how to check and whether I will be doing damage to the turbos by driving with it this way, I would appreciate it. Thank you Quote Link to comment Share on other sites More sharing options...
Ric Posted June 23, 2018 Share Posted June 23, 2018 It will be fine. You can test the bov by applying a pressure on one of the large hoses then using a vacuum on the smaller one. If the pressure goes to the other big hose it’s working Quote Link to comment Share on other sites More sharing options...
