- The wait is over! Here are the dyno results of my walnut blasting experiment. I am very sorry for the delay, it has been a crazy race season and I am doing this all by myself!

In this series, I measure the power losses caused by air-oil contamination and intake valve carbon deposits. There are many videos documenting the benefits of walnut blasting, the preferred method of cleaning. Though I could not find any that verify horsepower gains on a dyno. The engineer in me had to know!
All engines are prone to some form of carbon buildup, but Turbocharged Direct Injection Engines are particularly vulnerable. Because all of the fuel is sprayed DIRECTly into the cylinders, there is no way to keep the intake valves clean (like Port Injection does). The mandatory emissions-compliance PCV and EGR systems recirculate fuel and oil vapors back through the intake, which inevitably burn onto the hot intake valves, creating a thick carbon coating. The extra crankcase pressure from the turbo puts extra oil and strain on these systems.
As this carbon builds up, it can start to interfere with the flow of the air into the cylinder. This could cause misfires, loss of power and fuel economy. Left unchecked, this carbon can even cause catastrophic damage.
After 4 years of beating, I could tell my 2.3L Ford EcoBoost was not hurt, but definitely not running at its peak. It exhibited rough idle and misfires, though nothing severe enough to trigger a Check Engine Light. While I wasn't 100% sure of the cause, I suspected that at over 100,000 miles, I could have carbon deposits on my valves.
It turned out that this was well worth the investigation.

In Part 1, I performed a baseline dyno measurement on my 2015 Ford Mustang Ecoboost, after reaching 100,000 miles (90k added by me daily driving) and over 150 days performance driving on closed courses in 4 years:

In Part 2, I performed the walnut blasting process, thoroughly documenting my process and all pitfalls that I discovered. The job was completed over an entire weekend, for less than $200:
• Watch This BEFORE You ...
DISCLAIMER: I do not intend for this video to be a direct tutorial. It was made for entertainment purposes to demonstrate what I did to perform this process successfully. This is an invasive procedure, not ideal for a novice mechanic to perform on their own. If you screw this up, you may destroy your engine. I am not liable for any decisions that you make as a result of watching this video. You are solely responsible for the outcomes of any attempts to emulate any of the procedures depicted in this video. Your results may vary.

In Part 3 (this video), we discuss the results of the cleaning and testing. They are incredibly significant, greater than I ever could have predicted. We also discuss the reasons for this carbon buildup, the regulatory and consumer pressure that are partly to blame, and what you can do to prevent this buildup from occurring on your vehicle.

Great video!!! I loved the editing of the video , Greetings from Dominican Republic, Im currently Fixing my 2015 Ecoboost mustang, The headgasket issue with the coolant is driving me crazy, Any advices are welcome!
Great video Pete!
Fantastic content. Awesome editing too 🙌🎉
This whole video is glorious.. that lion king part at the end
Great video, very informative!
I had to get a new dd and went for a new Toyota that has the d4s fuel system. Direct and port injection and runs on port more than half the time so the intake valves stay clean. I don’t get why that’s not the standard for every oem.
Many are working on adding it, but it's been far too long on numerous platforms.
The power recovered is going to be small compared to some engines that will develop misfires and codes due to carbon build up. I have had several cars that could not pass inspection due to misfire codes caused by carbon build up.
True! At least my car wasn't running that bad. But it definitely developed those drivability quirks - 14:01 - it wasn't doing any of that when I first got it. The cleaning not only cured them, the power gain was instantly noticeable. I'm glad I did the before and after dyno pulls to confirm.
I worry about this with my ‘05 Maserati Spyder. It is an older car but the Ferrari/Maserati F136 V8 uses direct injection.
Neat! There's a guy on here that did a cleaning to his Ferrari: th-cam.com/video/mY8kYXfhvyE/w-d-xo.htmlsi=hyrWcB46g8GTGIiV
Yeah it is definitely one of those things to look out for. Power loss isn't the end of the world, as long as you don't have drivability issues I would enjoy the car. Since I race I need to squeeze every horse out of this pony, and I wanted it clean before tuning. Glad I did!
Wow. Thanks for the data.
would a oil catch can help reduce the build up?
It seems like it has. I've had one for 20,000 miles now. Planning a follow-up video.
Very well done! Great job.
The soundtrack is pretty good too!
Toyota has had port and direct injection for what? 7,000 years now?
Been using Crc to clean my pcv (I should just install a catch can) I've been looking at european low SAPs oil to reduce intake build-up. Been using GF 6 oil, but not sure how to figure out which is low SAPs so decided to just use european marketed oil.
Will a catch can avoid dirtying the pcv? Or will it just reduce the dirt gathering in it?
@@danibj Only reduces buildup. Much of the garbage is the PCV vapors as well as the EGR exhaust carbon.
@@reubenmorris487 thanks! I have the catch can, bought the car with it, so will be using crc very soon
haha I always say Golf clap... nobody ever gets it.
Seafoam once an oil change keeps mine clean 🤙🏽
Ford recommends against it, but I may start. We'll see how it looks when we pull the intake, catch can installed.
@@pete_bruschi_racing because it doesn’t have their name on it probably. I use it in everything on the farm as well 🤙🏽
🤙🏾🙏🏾
Get to the process. We all know the VW, etc stories.
The process was covered in the previous video! Mentioned at 2:23 th-cam.com/video/ct-n2xV4Ve0/w-d-xo.htmlsi=G1K7Iv0gSre894gU
Direct injection?
13:08 Direct Injection. All fuel is sprayed into the cylinder. As opposed to Port Injection that sprays outside the cylinder. Or a Carburetor that sits on top of the intake. The closer you get the fuel to the cylinder, the less losses you have, but you can create issues like this carbon buildup.
@@pete_bruschi_racing D.I. also puts more soot into the oil and will make the car blow out more black smoke under full-throttle.
