The Boomba Racing Blow-Off Valve had been designed is a high-performance recirculating blow-off valve that has been fabricated from machined aircraft grade billet aluminum that features an internal brass piston that has been pressure tested to withstand up to 70psi of pressure. This means it is strong enough to handle the most aggressive of turbo builds. The spring pre-load will determine the pressure differential required across the piston before the BOV opens and releases the pressurized intake charge. 

This is an ideal upgrade for those of you who have performed enough modifications to increase both the horsepower and the boost which could potentially surpass the limits of the factory blow-off valve, and cause a leak. The Boomba unit is a direct bolt-on replacement that will come supplied with a vacuum line for a simple installation.
