Nizpro are leading devlopment with these particular cars for a reason. The link below supports what Ralphie is saying. And 10 years on still rings true. I believe the key to Simon's research lays with the fact that an Engine Dyno, and Turbo Tacho were used for testing. I personally approached Nizpro on this very subject, and even after all this time, and some massive boost being produced. They stated that they have never seen premature wear from a BOV removal. Saying that wear patterns would be located in differing positions on the shaft, if a BOV removal was the culprit. http://autospeed.com/cms/title_Nizpros-Simon-Gishus-Part-2/A_1457/article.html Cheers, and Happy New Year to all.

I understand that car makers have lots of pressure to reduce running costs and make them more appealing to the mainstream public someone at ford just made a mistake.

Id agree nizpro seem to be leading developments though not sure I agree in this instance.. Not sure a rally car is a good point of reference with the number of turbo and motor rebuilds, not to mention anti lag.. Maybe this is one of the points everyone in the industry cannot agree on.. Ill stick to the safe side of the line, thanks for the link. Sent from my GT-I9100 using Tapatalk 2 Link to comment Share on other sites More sharing options...

Red R6 Donating Members 41 Member For: 12y 28d Posted 01/01/13 05:16 AM Share Posted 01/01/13 05:16 AM So you agree now that compressor surge does affect turbo life? Link to comment Share on other sites More sharing options...

Red R6 Donating Members 41 Member For: 12y 28d Posted 01/01/13 05:54 AM Share Posted 01/01/13 05:54 AM The point im trying to get across is that there is the potentual we all have different mods and boost levels and it isnt somthing we need to consider before removing the bov.Turbosmart link -The pressure within the intercooler piping continues to increase until the compressor reaches its pressure limit. When it reaches this limit, it cannot flow the air any more and the built up air pressure inside the intercooler and pipe begins to flow backwards through the compressor which is trying to flow air forwards.The result of this reversal flow of air is the immediate deceleration of the turbocharger and a high load on the bearings which support the compressor/turbine shaft. At low turbo speeds and low pressures, the deceleration of the turbo and the load on the bearings is low, I.e. a small amount of fluttering at low engine speeds and throttle movements is negligible.At high turbo speeds and high pressures, compressor surge during a gear change can be damaging to the bearings of the turbocharger as the deceleration rate of the turbocharger is high and the reversal airflow through the compressor is high Link to comment Share on other sites More sharing options...
