any using a Greddy BOV? i bought a S-type for my future build up and was curious to how the Greddy s type sounded. |
dont use it on a blower car. you need a procharger or vortech bypass. |
I'm using a Greddy Type R-used it on my Novi 2000 with 18psi on my Mustang with no issues-Jimmy LaRocca recomended it back in the day. http://i127.photobucket.com/albums/p.../GreedyBov.jpg http://i127.photobucket.com/albums/p...greddybov1.jpg |
alright cool,does it sound good? |
When i get a dyno vid i'll post it and let you decide. |
sweet sounds good |
Greddy makes a killer BOV, and they sound very nice |
cool glad to hear that then. |

Im using 2 x Greddy Type RS BOV's As long as they dump air when you close the throttle, ANY BOV can be used, as long as it can flow sufficient quantity of air, and spring tension used is suitable for the application. Sound from mine isnt really that noticeable most of the time. They do whistle slightly at part throttle and idle sometimes, which is a little annoying. |
whats really the difference from the Type S from the Type RS? |
Havent a clue.... I think the RS might be slightly larger diameter. Mines 38mm. |
well i guess once the motor is all together and running and the sound isn't what i want then maybe i will get a Vortech BOV instead. Greddy sure sound good on WRX's and tuners like that. but are motors and exhaust are so loud so it drowns out sound also. |

Sound from mine isnt really that noticeable most of the time. They do whistle slightly at part throttle and idle sometimes, which is a little annoying. 1. they arent open at idle, which sometimes can attribute to surging at idle. 2. theyre not open when downshifting, which can cause strain on the blower forcing air against a closed throttle plate 3. They chirp at part throttle sometimes. |

They chirp at part throttle sometimes. If you adjust them, they can be open at idle. Although if you have an airflow meter, you dont necessarily want them open at idle. Again, that depends how they are set. If they "chirp" at part throttle, then they are either close ( read setup wrong ) or they do not flow sufficient air. One BOV was insufficient for my car, hence I run 2. I have 1 internal spring removed, and the adjuster quite slack, but not fully slackened off. |
