When i had these two new hybrid K16/24's installed on my 993 lump





I set off for Le Mans 2008, i got nearly 2 miles down the road and the new BOV'S i'd had fitted



Failed! What happened next was strange. The BOV's were second hand, they didn't open on vacuum. The right hand turbo stalled, the nut then came off the end of the shaft on the compressor side and the left hand turbo sucked it all the way around the back of the intake and into the compressor of the LH turbo, Basically destroying both turbos. Not a good day!
Stock Porsche BOV's in now and all is well, RS Tuning use the stock 993tt BOV's in even their most extreame road turbo builds.
Lesson being, use proper BOV's
