I decided to order the helix BOV for my 07' cooper s from Outmotoring.

Anyone have installation instructions? The link is broken for the instructions on helix13 website.

 

The installation Microsoft Word document downloads just from their install page; I just did it:

Why on earth did you order this? I've had my fair share of play with these and they are bad news for the R56. RETURN IT!

 

I've read many good things on this and have buddies who have had no issues with it. What seems to be the problem?

 

The N14 / N18 engines are designed with diverter valve, to recirculate unused boost back into the intake system.
This is considered a "closed-loop boost" system where the ECU knows how much air has entered the intake system through the MAF sensor.
With a blow-off valve (BOV) dumping the metered air into the atmosphere, some have experience CEL's referring to fuel trim or 'boost specification not reach' type fault codes.

Bluefox is spot on. I wrote a good example of my experiences with these in my local MINI club online garage:

They are truly a waste of money.

Steer Clear of Vent to Atmosphere (VTA) Blow-off Valves (BOVs)
If you’ve got an R56 S, jusy say no to VTA BOVs. I had an HKS blow-off valve for almost a year and after a couple days on the track I knew it had to go. The trouble is that the engine’s ECU is already controlling a stock diverter valve on the turbo and adding another mechanical valve downstream only confuses the ECU. A check engine light will occur when the VTA BOV vents and the stock diverter valve is still closed. I believe the ECU has logic that the intake manifold pressure against loading conditions and if suspicious values are detected, a check engine light will populate for a boost leak. The real bonus is that the engine goes into a torque derate because it thinks there is a boost leak. So in “English,” the engine acts like there is no turbo!! My experience with the HKS SSQV was that when I would slightly lift the throttle at times, the blow-off valve would vent when it really didn’t have to, the stock diverter valve remained closed, the check engine light for a boost leak would populate, and then when it came time to go wide open throttle there was no torque! Lucky for me, I was able to sell the HKS SSQV kit on eBay to some ricer lover with very minimal financial loss.
