Porsche 992 Power Upgrades (Cats & Tune)

There’s something stupid inside of me that keeps wanting more. Is the 992 Turbo S fast? Hell yes. Can it be faster? Hell yes. Because I’m not what people would call “smart” I have been conned into pulling out my ECU, having it reflashed and adding in 100 cell catalytic converters. What do I hope to achieve? Power, friends. I’m looking for more power. One hundred horsepower more, to be precise.

Thank goodness Dagan seemed like he knew what he was doing.

The ECU is out and in California waiting for some special sauce. I wonder when I’ll get it back 🤔

I’ve got VBOX stats for this car in it’s stock configuration, so I’ll be very curious to see where we end up following these modifications. I would think we’d be low tens here in Utah. We’ll see shortly.

Okay, so here’s the build progress:

We got the DME back and some new catalytic converters. Time to pump this thing up to the next level.

Turns out that the cats from Europe have weird tubes coming off of them- those had to go! So we put our project on hold until we could sort that out. Luxe hooked me up with an incredible welder (video below) and then we were ready for the install.

These are the aftermarket parts we put in- new 100 cell catalytic converters and BME air filters. The flow difference on these to cats should be insane.

Dagan, Bryce and I (mostly Dagan) got the install done without incident and then we were ready to do some real world testing. The new cats give the exhaust a nice throaty sound and you can hear the turbo whistles a bit better- it’s perfect. However, it’s hard to feel a power difference in your butt dyno so before the weather got bad I snuck out my my favorite spot and did a few quarter mile runs with with my VBOX. Wow.

91 pump gas, damp roads, high flow cats and a tune got me down to 10.08 at almost 139 mph. That is nuts- it’s the fastest quarter mile I have personally run. If I launch harder (at 5K rpms instead of 4K) and hook I’m 100% sure I can break into the 9’s. A few years ago my 991 was fighting to get into the 10’s! I am so impressed with the 992 platform- a nearly stock nine second daily driver. Unreal. These mods aren’t cheap, but they’re fun! Hoping to get even quicker this spring as well 🤞🏼
