Unleash Your Raptor: The Ultimate Blow Off Valve Upgrade Guide

The Ford Raptor blow off valve is one of those upgrades that can really transform your truck's performance and sound. I've been tinkering with Raptors for years now, and I can tell you firsthand that adding a quality blow off valve (BOV) is a game-changer. It's not just about that sweet "pssshhh" sound (though that's definitely a perk). A good BOV can actually protect your turbo and improve throttle response.

But here's the thing - not all blow off valves are created equal. Especially for a beast like the Raptor, you need something that can handle serious boost pressure and flow. I've seen guys slap on cheap universal BOVs and end up with all kinds of issues. Trust me, you don't want to go that route.

Let's dive into everything you need to know about upgrading your Ford Raptor blow off valve. I'll break down the benefits, top options on the market, and walk you through the install process step-by-step. By the end, you'll be ready to take your Raptor's performance to the next level.

Why Upgrade Your Ford Raptor Blow Off Valve?

Before we get into the nitty-gritty, let's talk about why you'd want to swap out your stock blow off valve in the first place. The factory BOV on the Raptor isn't terrible, but it's definitely designed with compromise in mind. Upgrading this part can make a huge difference in your truck’s performance. Here are the key benefits of upgrading:

Improved Turbo Protection

The primary job of a blow off valve is to release excess pressure when you let off the throttle. This prevents that pressure from slamming back into the turbo, which can cause premature wear. A high-quality aftermarket BOV will react faster and vent more efficiently than stock, making it well worth the investment. This will ensure that your truck can handle even the most demanding conditions.

Better Throttle Response

By venting pressure more quickly between shifts, an upgraded BOV allows the turbo to spool back up faster. You'll notice crisper, more immediate power delivery when you get back on the gas. It will also improve your truck’s overall performance and give it a more responsive feel.

That Sweet, Sweet Sound

Let's be real - the sound is a big part of the appeal. A good blow off valve produces that signature "pssshhh" when you let off the throttle. It's like audio confirmation of your truck's performance potential. You’ll definitely turn heads when you hit the gas.

Increased Boost Holding Capacity

If you're running increased boost on your Raptor (and who isn't?), the stock BOV can struggle to keep up. Aftermarket options are designed to handle higher pressures without leaking or sticking. They will provide you with the peace of mind of knowing your truck is running at peak efficiency.

Top Ford Raptor Blow Off Valve Options

Now that we've covered the "why," let's look at some of the best blow off valve options for your Raptor. I've personally tested most of these, and they're all solid choices:

Turbosmart Vee Port EM BOV

This is my top pick for the Raptor. Turbosmart knocked it out of the park with their electronically managed (EM) design. It's a true plug-and-play solution that integrates perfectly with the Raptor's ECU, making it one of the best options on the market.

Key features:

  • Fully electronic operation for precise control.
  • Billet aluminum construction.
  • Capable of handling up to 50 psi of boost.
  • Direct bolt-on fitment for 2013+ Raptors.

Go Fast Bits T9464 BOV

GFB makes some seriously good valves, and their Raptor-specific offering doesn't disappoint. It's a more traditional mechanical design but with some clever engineering to work with the Raptor's setup.


  • Fully recirculating design (no venting to atmosphere).
  • Adjustable spring pre-load for fine-tuning.
  • Direct replacement for the OEM valve.

Boomba Racing Blow Off Valve Adapter

If you want the flexibility to run different BOVs, Boomba's adapter is the way to go. It lets you install virtually any 50mm blow off valve on your Raptor, making it very versatile.


  • Opens up a world of BOV options.
  • CNC machined from 6061 aluminum.
  • Includes all necessary hardware.

Installation Guide: Upgrading Your Ford Raptor Blow Off Valve

Alright, let's get our hands dirty. Installing a new blow off valve on your Raptor isn't too difficult, but there are some important steps to follow. This step-by-step guide will make things easy.

Step 1: Prep Work

First things first, make sure your engine is cool. You'll be working near some hot components, so give it time to chill out. Gather your tools - you'll need basic hand tools and potentially a torque wrench.

Step 2: Access the Stock BOV

The stock blow off valve is above the skid plate.

Step 3: Remove the Factory Valve

Disconnect the electrical connector from the stock BOV. There are typically two bolts holding it in place - remove these and carefully pull out the valve.

Step 4: Install the New BOV

This will vary slightly depending on which valve you chose. For direct replacements like the Turbosmart EM:

  1. Place the new valve in the stock location.
  2. Secure it using the provided hardware (or reuse factory bolts if specified).
  3. Reconnect the electrical connector.

If you're using an adapter like the Boomba:

  1. Install the adapter plate where the stock BOV was located.
  2. Mount your chosen aftermarket BOV to the adapter.
  3. Connect any vacuum/boost lines as specified in the instructions.

Step 5: Double-Check Everything

Before firing up the engine, do a thorough check:

  • All bolts are tight and torqued to spec.
  • Electrical connections are secure.
  • No vacuum lines are pinched or disconnected.

Step 6: Test Drive

Start the engine and listen for any obvious leaks. Take the truck for a spin, paying attention to how it builds boost and the sound when letting off the throttle. If everything feels good, you're all set.

FAQs about Ford Raptor blow off valve

Can a blow off valve damage your engine?

No, a properly installed and functioning blow off valve won't damage your engine. In fact, it helps protect the turbo by releasing excess pressure. However, a faulty or improperly sized BOV could potentially cause issues. That's why it's crucial to choose a reputable brand and follow installation instructions carefully.

Do blow off valves hurt the turbo?

Quite the opposite. A good blow off valve protects your turbo. It prevents compressor surge, which is when pressurized air slams back into the turbo when you let off the throttle. This surge can cause premature wear on turbo bearings and seals. A quality BOV releases that pressure safely, extending turbo life.

What does a blow off valve do on an F150?

On an F-150 (or Raptor), the blow off valve serves the same purpose as on any turbocharged vehicle. It releases excess pressure from the intake system when you close the throttle. This prevents compressor surge, improves throttle response, and can produce that characteristic "pssshhh" sound. In the case of the Raptor, the stock valve is designed to recirculate this air back into the intake.

What does a blow off valve do?

A blow off valve (BOV) is a pressure release system for turbocharged engines. When you let off the throttle, it vents the built-up pressure in the intake system. This serves several purposes: It prevents turbo damage from compressor surge, improves throttle response by allowing the turbo to spool up faster, and can produce that distinct "pssshhh" sound enthusiasts love.


Upgrading your Ford Raptor blow off valve is one of those mods that pays dividends in both performance and fun factor. You're getting better turbo protection, improved throttle response, and yeah - that sweet blow off sound doesn't hurt either. A blow-off valve is one of the many mods people make on their trucks, but it’s a popular choice. It’s important to choose a blow-off valve from a well-known brand.

Just remember, quality matters here. Stick with reputable brands that have Raptor-specific options. The last thing you want is boost leaks or check engine lights from a poorly designed valve.

If you're even somewhat mechanically inclined, the install is totally doable in your driveway. Take your time, follow the steps, and you'll be enjoying that "pssshhh" in no time. And trust me, the first time you hear that crisp blow off after a pull, you'll wonder why you didn't do this upgrade sooner.
