I got my forge bov and installed with the med. spring that italready intalled in it. But it seems like when i am cruising around around 3000 to 4000 rpms it feels like the valve isn't sure whether or not it wants to be open or closed. should i add the 2 shims it came with or just put the stiffer spring in?

 

I think even with the stiffer spring they do that. The forge valves are ok alot of people run them but they surge alot at part throttle

 

oh okay. ya i noticed they tend to surge if ur in that grey area of part throttle and slight load on the motor . I'll just play around with it and put the stiffer spring in and see if that reduces it. thanks for the info mike

 

If it gets to annoying the only one that really works well to not sugre in my research was the APS deul vent. I just bought one and put it on my car but ill never know since I just sold my car for $24,500 and its getting picked up next week

 

you sold your car. what u do that for ?

 

hey i'll trade ya . swap out the aps duel vent with my forge bov . the guy will never know lol. Hey it sounds like a good idea to me

 

Evo 9 bov ftw!!!

 

agreed but not for my car since I outflow the IX DVs capabilities. For the stock turbo all the way though

 

I sold it so I can get a Supra. I sold it for about double what I owe so I will be banking over $11k in cash. I also sold it for $2k more than I paid for it 3 years ago, which at the time it was bone stock and only had 12k miles now it is prettymodded and has 44k miles on it.

Oh and he knows the BOV it has on it because I send him the full mods list and he also knew because I told him I needed to swap out the HKS for it before I sold the car to him

 

thats cool. good luck with the supra. i'm jealous
