Description

An inexpensive upgrade for turbo MINIs

The ALTA Blow Off Valve Spring Upgrade is a great alternative to complete BOV replacements. Fits all MINI Turbo Models including Cooper S and JCW! The ALTA replacement spring is a simpler, less expensive and better performing upgrade.

So Simple, Yet So Effective

The ALTA BOV Spring Upgrade for your stock Blow Off Valve is a very effective way to make your Turbocharged MINI hold more boost between shifts. This reduces turbo lag and boosts performance. The stiffer spring still allows for normal functioning of the BOV, but keeps more pressure in the boost tubes to prevent any lapse in power.

Installs In About 30 Minutes!

Anyone with simple hand tools can install this part in under 30 minutes. Simply remove a handful of parts including the electronic BOV and then just replace the factory spring and your done! Check out the instructions above for a step by step explanation.

Tested to hold 40 PSI of boost!

Our product designers developed this test fixture to test a variety of spring rates before even attempting an in-car test.

A key to the design of this part is ensuring the spring is not too stiff. Because this is an electromechanical device, it is crucial that electronic solenoid is able to open the blow off valve. The ideal spring rate was chosen and then tested to work perfectly in excess of 40 psi of boost! While you will never see that level of boost, it is comforting to know that your blow off valve is now up to the task of handling anything you throw at it!

So Many Features

Here is why the ALTA Blow Off Valve Spring is the ideal upgrade:

  • Custom made heat-treated 17-7 Stainless Steel Spring
  • Rated for over 7,000,000 cycles
  • Makes turbo response better between shifts and less turbo lag
  • Holds and vents 40psi perfectly
  • A fraction of the cost of complete blow off valve replacements

Wikipedia

A blow off valve (BOV) or dump valve is a pressure release system present in most turbocharged engines. Its purpose is to prevent compressor surge, and reduce wear on the turbocharger and engine. Blow off valves relieve the damaging effects of compressor "surge loading" by allowing the compressed air to vent to atmosphere, making a distinct hissing sound, or recirculated into the intake upstream of the compressor inlet. The turbo MINI Cooper S and JCW both have BOVs that are controlled by the ECU. These large solenoids opens the valve and dumps the excess boost pressure. The ALTA Blow Off Valve Spring upgrade is a stiffer spring to make the valve close faster after shifts and hold more boost! » Read More
