Hi, I fitted a MBC onto my v70 today (2.5T 98) and it only produced 2psi with it wound right down and right up, now before I fitted the MBC i was only getting 4-5psi on the boost gauge. But I took the MBC back off and im now getting 8-9psi?

Anyone tell me why the MBC was only giving me 2psi?

I think I did, put the arrow pointing toward the actuator and the other pipe from the nipple on the turbo to the other part of the MBC

The pipe from turbo goes to the lower part of the mbc and the actuator pipe to the side of the mbc.What mbc is it,r u sure its not a bleed valve?

It's deffo a MBC, it's just a cheap basic one, I bought it off a guy on VOC? Looks like one off eBay

S'true, M-R-P had one, I think you'll remember the RR day in Feb, after his car was on the rollers he couldn't wait to get rid of his.

He probably gave it away to some clueless halfwit looking for a cheap power gain

It worked fine on the road but on the rollers...

I had a £15 special & loved it, a lot more aggressive than any remap I've driven & as good enough to get me my 14.557

'Bout time you beat that time aint it Pedro?

**Dan H** · Wednesday 22nd May 2013, 10:37

Well I wasn't too bothered about if it was going to work or not, it's a cheap thing. But was more concerned about it now having 8/9psi from the 4/5 after changing two vac pipes around, because it has been like that since the day I bought the car

**Kingsford G** · Wednesday 22nd May 2013, 11:19

U do know that with mbc fitted u mustn`t floor it until 3500rpm

**Dan H** · Wednesday 22nd May 2013, 11:44

Yeah I know, but still wasn't making any difference, was still going to 2psi
I took it off yesterday anyway and haven't put it back on

**Kingsford G** · Wednesday 22nd May 2013, 12:48

**Dangerous Dave** · Wednesday 22nd May 2013, 13:01
