Blow Off Valve Recirculation Kits
BLOW-OFF VALVE RECIRCULATION KITS
This is where you will find all of the components to either recirculate, block or get replacement recirculation kits for your blow-off valve. Now we all love blow-off valves because of the unique sound that they make. However, there are some of you who need the performance out of an aftermarket blow-off valve in terms of holding boost when you make more power that surpasses the limits of your factory diverter valve. But you may not like the attention that aftermarket blow-off valves make so you choose to keep them recirculated. And then there is the rest of us who are loud and proud and want to annoy everyone else on the road with all of the blow-off valve noises.
Here, you will find all of the components to make that possible. You will find hose plugs in a variety of different sizes to accommodate your setup, and there are some hose kits that will work with specific aftermarket blow-off valves. All of these components are brought to you by some of the most established brands in the aftermarket industry that include but not limited to Turbosmart, HKS, ATP Turbo, and others to make your blow-off vale silent or louder.
Check out the rest of our blow-off valve components to keep your turbo happy.
With the amount of aftermarket blow-off valve options that we have available from the likes of Tial, Go Fast Bits, and Turbosmart, you have a variety of blow-off valve springs to choose from. You can choose from soft to stiff spring rates, and this is why you need to have the appropriate spring rate. If you are running a stock turbocharger with stock boost levels, then it would not make sense to have an aftermarket blow-off valve with a stiff spring as it would not open to relieve boost between shifts. This could result in compressor surge issues as the pressure that would otherwise be relieved out of your factory bypass valve or an aftermarket blow-off valve with a proper spring would push the pressure back through the compressor side of the turbocharger. Now if you are running larger boost levels or have a larger turbocharger that moves more air, a softer spring could leak boost under load not allowing you to hit your proper boost targets.
Now generally, when purchasing an aftermarket blow-off valve, the included spring is a good medium to hold higher boost levels, while properly relieving boost at lower levels. And back in the day for some of us that made big power in the late 9s to early 2s, we would result to installing an additional blow-off valve. Now that the majority of aftermarket options are serviceable in terms of replacing seals or pistons in some cases, you can now upgrade or downgrade the blow-off valve spring to suit your power levels.
