How To Install BOV On Non Turbo Car
Are you looking to install a BOV on a car that doesn’t have a turbo? Not a problem! This guide will explain if such a technique exists and work. Plus, we’ll show you some other ways to make your car more performance-friendly. Ready to get started? Read on!
Can you install BOV on a non-turbo car?
A blow off valve (BOV) can’t be installed on a normally aspirated car; they’re just for forced induction engines. Regardless of how much you enjoy the sound.
Normal engine operation.
Because this isn’t a post about turbochargers, we’ll disregard how they operate and assume they work. The turbocharged air enters the engine through the intake. If the throttle is open, that is. So, what happens if you take your foot off the accelerator? There’s nowhere for the compressed turbocharged air to go. It hits the closed throttle plate and returns the opposite direction up the intake manifold. You are returning to the turbine. The high-pressure air striking the turbine blades from the wrong side of the turbo reduces boost by slowing the rotating turbine. The turbo must slowly spin up again when you press the accelerator pedal to achieve maximum boost. It is a disaster. It’s terrible. The reverse surge of turbocharged air could damage the turbine. It is also a problem. It’s terrible.
This is why there are blow off valves. It discharges turbocharged air that has been forced down the wrong side of the intake manifold into the atmosphere: longer turbocharger life, faster spool, and improved transient responsiveness benefit. Of course, there’s the problem of the stock standard ECU expecting air but not getting it, resulting in too much gasoline being pumped in, but that’s another story. There is a different sort of blow off valve for automobiles with that problem (typically due to the installation of Mass Airflow Sensors) that recirculates turbocharged air back into the intake rather than discharging it into the atmosphere. However, it sounds a lot less cool, hehe.
Recirculating blow-off valves send air back into the intake
You can’t put a blow-off valve on a naturally aspirated car since a vacuum is used for induction (sucking air into the engine). Instead of the turbine pushing compressed air into the engine, the engine suckers it in. There is no air pushed in when the throttle is closed, and there is no boost bouncing back into a non-existent turbocharger turbine.
So that’s what blow off valves are for and why turbocharged automobiles only have them. You’ll need a turbocharged car if you want that wonderful sound that turbocharged cars make when shifting gears. It’s similar to a Perdana V6 Twin Turbo.
Due to its location, such cars may not be able to accommodate a BOV. It is essential to consult a mechanic or vehicle specialist if you are unsure whether or not your vehicle can support a BOV.
Can I run a BOV without a tune?
Most experts recommend having your vehicle tuned at least once a year to maintain optimal performance. A tune will include checking the air pressure, oil level, and fluid levels. Additionally, it is important to have your brakes serviced every year, and your tires rotated. If you are in doubt about whether or not your vehicle needs a tune, please don’t hesitate to contact a professional.
Can you make a non-turbo car, turbo?
No. It cannot work.
