Paxton-blown behemoth has a beautiful blow-off valve ‘hiss’ to die for.
The video above comes to us from the ThatGuyMarin YouTube channel and it features host Nico Marin doing some data-logging with his Ford Mustang GT. The car had a big Paxton supercharger installed prior to this video, so he has to send some logs with the base tune to his tuner for tweaks that will lead to more power and safer power.
However, as we see in the video, this process requires him to drive the car around at low engine speeds, staying out of the boost and doing lots of idling. It is not a particularly exciting process, forcing owners of freshly-supercharged cars from tearing up the streets right away, but without this process, he may not be getting the most from his engine.
The video begins with Marin explaining that he recently had a big Paxton supercharger installed in his Ford Mustang GT. It is running on a base tune and for the data-logging process, he has to follow strict instructions that include no boost and no wide-open-throttle. He has to idle the car for a few minutes, then hold engine speeds at set levels for a few minutes, then he finally gets to hit the street.
Unfortunately, the on-street action is reserved to gentle, no-boost pulls in third gear from 25 miles-per-hour up to 5,000 rpm while the laptop on the passenger seat records all of the key information for the tuner.
Roaring Pony
While Marin isn’t allowed to really push his Mustang GT at all while data-logging, we can still hear the roar of the exhaust and the hiss of the blow-off valve when he lifts from higher engine speeds. Even without big boost, the car sounds pretty great as he drives around town and on the pull from 25 mph to 5,000 rpm, we get just a piece of what the blown Ford pony car will sound like when the driver is allowed to let it stretch its legs.
After recording the information, he takes the Mustang for a drive to Steak N’ Shake where he gets a burger that he eats with his dog while sending the information from the logging session to his tuner.
Again, we don’t get to see much action, but this process has to be completed to get the most from the supercharged engine build and when Marin gets the updated tunes from his guy, we can bet that this Mustang is really going to scream.
In the meantime, crank up your speakers and enjoy this walk-through of the data-logging process.
"Before I was old enough to walk, my dad was taking me to various types of racing events, from local drag racing to the Daytona 500," says Patrick Rall, a lifetime automotive expert, diehard Dodge fan, and respected auto journalist for over 10 years. "He owned a repair shop and had a variety of performance cars when I was young, but by the time I was 16, he was ready to build me my first drag car – a 1983 Dodge Mirada that ran low 12s. I spent 10 years traveling around the country, racing with my dad by my side. While we live in different areas of the country, my dad still drag races at 80 years old in the car that he built when I was 16 while I race other vehicles, including my 2017 Dodge Challenger SRT Hellcat and my 1972 Dodge Demon 340.
"Although I went to college for accounting, my time in my dad’s shop growing up allowed me the knowledge to spend time working as a mechanic before getting my accounting degree, at which point I worked in the office of a dealership group. While I was working in the accounting world, I continued racing and taking pictures of cars at the track. Over time, I began showing off those pictures online and that led to my writing.
"Ten years ago, I left the accounting world to become a full-time automotive writer and I am living proof that if you love what you do, you will never “work” a day in your life," adds Rall, who has clocked in time as an auto mechanic, longtime drag racer and now automotive journalist who contributes to nearly a dozen popular auto websites dedicated to fellow enthusiasts.
"I love covering the automotive industry and everything involved with the job. I was fortunate to turn my love of the automotive world into a hobby that led to an exciting career, with my past of working as a mechanic and as an accountant in the automotive world provides me with a unique perspective of the industry.
"My experience drag racing for more than 20 years coupled with a newfound interest in road racing over the past decade allows me to push performance cars to their limit, while my role as a horse stable manager gives me vast experience towing and hauling with all of the newest trucks on the market today.
