The stock CRV is actuated electronically by the ECU, which may sound quick, but is actually a much more delayed process than one might expect; there are delays in the ECU when determining when to open the valve. This effects how quickly it blows off, which can lead to compressor surges, which leads to turbo damage or even failure. The ALTA CRV uses the tried and true method of using intake manifold vacuum and pressure, along with turbo pressure to open the valve. This means the moment you start to lift your foot off the gas, the ALTA CRV will start to release boost pressure keeping your turbo safe!
Cars with an ECU tune that increases boost levels will enjoy this part as you will never have to worry about it leaking under boost. The BOV is designed in such a way that the boost pressure pushing it closed is greater than the pressure trying to open the valve under boost. This means that 10psi, 20psi or 30psi of boost is no problem for it to handle!
The ALTA CRV consists of four very simple purpose built parts. The diaphragm and spring are the same items used on the high tech Borg Warner EFR turbochargers, which means they are meant to easily handle extreme conditions and not fail. This is one of those parts you install and never have to worry about again.Features:
- Quick Reaction
- Hold higher boost levels
- Improves both drivability and power
- High quality rubber diaphragm
