I have a 38mm megasonic and run 16 psi. It never leaks no matter what I do. Link to comment Share on other sites More sharing options...
hulk xr6t Member 160 Member For: 16y 11m 3d Posted 05/05/08 12:19 PM Share Posted 05/05/08 12:19 PM I have the Kompact series Turbosmart Plumback BOV and it is a direct replacement. No Adaptors needed. (it is the 25mm model).The reason why I bought it, it has a bigger internal valve (still vents through a 25mm opening and I wanted more confidence that the standard BOV isnt leaking any boost. Its also made of metal and Im sure Turbosmart built it pretty well. Sort of like making sure my XR6T eats all its vegetables...BUT..... I checked the instructions and the boost side and the exhaust side of the BOV are opposite to the standard Bosch BOV. I would advise anyone who simply installs it the same way the BOSCH unit works to check which way it vents as it works in the opposite manner.. The Vaccum line fits in it aganst the boost side.

hulk xr6t Member 160 Member For: 16y 11m 3d Posted 06/05/08 01:17 AM Share Posted 06/05/08 01:17 AM (edited) Sort of like making sure my XR6T eats all its vegetables... that's awesome!!You dont wanna be putting boost in there and the XR6T leaks it out like a kid avoiding eating his peas and chucking them under the table on the floor...Its my understanding though that under boost, soft or hard setting they wont leak boost. that's the reason why I bought it. There is much commentary in other threads/forums about if you leave it too soft it will leak boost.... Is that the same as if you pull a face and the wind changes argument or is it true...In saying that is the stock BOV known to leak boost??
