Guest ttoude Posted December 16, 2009 Share Posted December 16, 2009 From the general definition and some articles and videos it seems the BOV has no "Specs" i.e. there appears to be no BOV to Turbo ratio. It looks like its a matter of where the "lag" ends up in your setup. It seems to be more a fine tuning game with different spring types. Am I right?

Apex944 Posted December 16, 2009 Share Posted December 16, 2009 Greddy RS is plenty. I also agree that the Greddy RS is more than enough for a street car. I had one on my '88 Rx7 with a hybrid T04 turbo and it was more than enough for that car. I'm sure that the Greddy S type is even good enough for any factory nissan turbocharged car. Find a Greddy S or RS or an equivalent and you'll be set. They are adjustable of course as well as the RS can be recirculated back into the intake to get rid of the lag between shifts and the slight rich mixture that is the cause of the lag.

Mayolives Posted December 17, 2009 Share Posted December 17, 2009 Here's a simple straight forward article on BOVs: http://www.siliconeintakes.com/stpg.php?page_id=bov This is a really good read. After fooling with BOVs for a long time, I now have a much better understanding of how they opperate. Thanks! Quote Link to comment Share on other sites More sharing options...
