Hey guys,
I need some help, I know I dont own en evo anymore as of this moment, as I've shared last year bout the project car im doing, evrything doing well, I got 362hp and 380Nm boosting at 1.2bars (about 17.64psi if im not mistaken) on a K20 engine. Now,I got a problem with my BOV, im using the HKS SSQV BOV and when I'm boosting about 0.7bars and above, its sounded weird, the sound like when u forgot to close your window fully then there's a really strong wind blowing; it sounded like that!
I asked some of my friend's opinion then they say that the HKS bov cant withstand the boost and horsepower of the car then it just leak or did a premature release or something like that
Just wondering if anyone has ever experience the same with their evo or any cars. Anyone knows is it the problem with the BOV or other things that making that weird noises
If it is the BOV, is there any BOV recommendation which BOV should I use? I asked some of them tuners/shops in Indonesia, some of them reccomend me to go with HKS SSQV Ver 2, or the Greddy type R BOV, but some of them said that the HKS Ver 2 and Greddy type R would be useless since the spring is so hard it wont open in my car, recommended me to go with 2 units of SARD (R2D2 if im not mistaken) BOV or to go with Blitz
Im confuseeeeeeeee.......Rich...Rob...Mark...Goku.... Anyoneeeeeee any input would be most appreciated.
