So Simple, Yet So Effective
The ALTA BOV Spring Uprade for your stock Blow Off Valve (BOV) is a very effective way to make your Turbocharged Mini hold more boost between shifts reducing turbo lag. The stiffer spring still allows for normal functioning of the BOV during light throttle lifts, but keeps more pressure in the boost tubes making it feel much faster shifting.
Installs In About 30 Minutes!
Anyone with proper tools can install this part in under 30 minutes. Simply remove a couple OEM parts, remove the electrionic BOV and replace spring with the ALTA spring and your done!
Tested to hold 40PSI of boost!!
This test fixture was created to be able to test the spring on a bench before it was installed on a car. This allowed us to test as much pressure as we wanted and make sure the BOV functioned as it should. Lets just say this BOV holds and vents more boost than you will ever see!
Key to the design of this part is ensuring the spring is not too stiff. Because this is an electromechanical device, its was important that electronic part of the system (solenoid) still was able to open the BOV. We settled on a spring rate that was about 50% higher than the JCW, which is tested to work perfect beyond 40psi of boost!
So Many Features
Our competitors simply resell the JCW Electronic BOV as an upgrade for your MCS. If you disect what makes these different you will find the entire part to be the same except one item, the spring.
