Today, I installed my LR-944-480-2 camshaft, and I must say it's a significant upgrade. I've been using VEMS for years, but I've always felt like the engine was somewhat restricted. So, I decided to give the LR-944-480-2 camshaft a try. Here are the specs: It features some degrees of advance ground into the cam, as you can see in the pictures. .480 lift, 233 duration, and 110° LSA. The cam is rifle drilled, which saves around 1.5 lbs (712 g), a nice bonus.
With its slightly longer duration and smaller LSA, the idle now has a pleasant lope, which sounds quite satisfying. The driveability is better than OEM, and I haven't noticed any loss of low-end power; if anything, it feels more responsive. The engine runs incredibly smooth and feels unrestrained up to the redline. It definitely allows the engine to breathe better than with the stock 9R OEM camshaft, especially when paired with my VEMS system. All in all, it feels like this camshaft is what Porsche should have done years ago.
I'll be heading to the dyno within the next few weeks. The last dyno run was in 2017 with the basic VEMS setup, yielding a result of 175 bhp @ 5900 RPM.

So here's the dyno sheet comparison, showing the before and after runs. Please note that the first run (red) was conducted in 2017 after the resonator delete and installation of a new air filter. The 2024 run (black) was performed with the resonator back in place and still utilizing the same (old) air filter, but with the addition of the LR camshaft. Both runs were completed on the same Superflow SF880E AWD chassis dyno.
228.8 NM nearly the same trq as the 944 2.7 l engine. 173 hp
