I'm running the COBB Stage 2 on my 05 FXT. Is there any compelling reason to replace the OEM BOV with something else and why?
No, it will make noise but you will lose precious power.Subinator said:I'm running the COBB Stage 2 on my 05 FXT. Is there any compelling reason to replace the OEM BOV with something else and why?
Basically, you're releasing air to atmosphere that has already been measured by the mass air sensor; consequently the ECU will send the wrong amount of fuel into the combustion chamber, causing the engine to temporarily run extremely rich. Not only can this cause bucking and hesitation, but in the long run it can also do some damage to your spark plugs or cats. Here's a good read on BOV's vs. recirc valves.IanN said:Quick question, Why would an aftermarket BOV = power loss with the stock turbo? I have a HKS SS BOV (left over WRX part) & I was planning on putting it on my fxt along with an intercooler & turbo upgrade. I don't want to use the HKS SS BOV if it means I would have any power loss no matter how cool it sounds. Any input is appreciated, Thanks Ian
Maybe not among the FXT owners, but if you look around in the WRX/STi scene here in the US, you will find that BOV's are extremely popular.oxymoron said:its funny how hardly any of u guys in the US run aftermarket BOV's and yet just about every single guy over here just has to have that sound. no matter how it effects the driveability. it would be a lot of ppl's first mods...crazy
