GFB's adjustable blow off valve allow for infinite adjustment between complete recirculation and complete vent-to-atmosphere. This allows the owner to choose, with a flick of the wrist, how loud they want their blow-off valve to be.
Awesome part, fits perfectly, sounds great and is super loud at 100% to the atmosphere and still has an awesome sound on full recirculation. I personally keep mine at around 50/50 and couldn’t be happier with it.
My car now goes Stutututu and Psssss what more can you ask for, great product!
Purchased this 2 weeks ago, prompt delivery , easy to fit myself (Basic mechanic skills), fantastic quality, Australian made, and works very well. Would happily recommend Cherry T&P for buying parts.
Very happy from the product and its condition.
This BOV is great in that you can adjust it by twisting the crown. Because it's in a difficult to reach area, get the lesser model whereby you have to remove the trumpet and screw in the block would be impractical. By just reaching in and twisting the crown it's made things much easier to adjust.
