Description

The COBB LF BPV is a compact and lightweight by-pass valve that is capable of holding very high boost pressure without leaking. Its updated design reduces control volume by 30% allowing for extremely fast venting of boost when actuated. Innovative engineering and precision manufacturing result in a compact package able to fit in the confines of a tight engine bay. Due to the low weight of the components, the moving parts in the LF BPV have less inertia and can respond faster than heavier components in other bypass valves. This updated design uses a Banjo-fitting vacuum port which provides 360 degree adjustability of hose routing. This results in a simpler install and less potential leak points than the NPT ports. This new design also includes a piston o-ring seal that is twice the diameter of the old design allowing more seal compression and reduced wear. Adjustability of the spring seat is no longer needed due to the updated spring and seal design which provides a 60% increase in clamping force at peak boost while maintaining similar operation at idle and transient loads.


Why?

A compact and very lightweight bypass valve that is loaded with features and reliably holds high levels of boost without leaks.

Rated 5 out of 5 by from Very Noticable Change In Sound and Acceleration Feel Just initial FIRST THOUGHTS here. Will report numbers later on after I do a few runs......... This instantly changed the sound of my Cobb SF Air Intake. At stage1 and stage 2 It used to dump air with a whipping "whoosh" sound but now that "whoosh" has changed to a sharper whistle like sound and even at low rpms around 2000-2500 it still shoots off a nice clear "psssfffff". Turbo feels like it won't take much to set it off / spool now and the air shoots through more easily. If you know your car, you'll feel the change without even looking at your Cobb AP gauges. Initial reaction reminds me of the new feel from a downpipe install that felt less restrictive......now it feels like the engine air flow became less restrictive and more direct free flowing. Just initial thoughts and feel here......no numbers to prove anything yet because I'm just having way too much fun right now.

Rated 5 out of 5 by from My experience buying this product!!! Looking for more responsiveness and or better boost hold this is for you. You may think it doesn’t sound like a atmospheric BOV being a BPV but you’ll still get that nice pshhhhh sound when you let out of boost. This product makes my car feel 10x better.
