Stock BOV

[unwrittenLaw]

Did anyone ever find out for sure if our stock BOV is leaking boost? I did a search but couldn't find out for sure..I know some people were going to put an aftermarket bov on and see if it made a difference...just wanted to know if the stock one is really leaking or if it is just inaccuracies in the boost gauges..

thanks

i thought the mazdaspeed came with a recirculating valve stock

Yeah, I think they do..but I've just read that people think its leaking somewhere, not sure exactly where though..

 

[perfworks]

what boost are you at with your gauge. where is the reference for the boost gauge coming from? and does your car have a problem running?

That would be a negative on the boost leak.

My boost gauge reads in hkpa and it usually hits around .45-46 when I'm fully accelerating..so I think you multiply that by 14.5 or something to get psi. I'm not sure where the Blitz gets its boost reading from, I'd have to go check that out since I didn't install it...And my car is running fine except for the hesitation/stumbling in 2nd and 3rd around 4-5k rpms.

I agree with turboge

i dont! DO I HAVE TO MAKE A VID! I hit about .70-.71 bar and by about 5500 rpms it will go down about .55-.52 bar. right before redline it sometimes goes to .48 bar.
