Some of you may already know we’ve been working alongside the Pumaspeed team, independently testing their incredible new G25-550 turbo! Right out of the box, the manufacturing quality is absolutely top-tier. It’s a beautifully straightforward, direct bolt-on fit—very similar to the S280.
We paired it with a fresh Turbosmart actuator and hit the dyno to dial in the software with the brilliant M’xed team. For context on the build, the car is running a stock-spec head (no porting and no high-lift cams), backed by a solid set of forged pistons and rods, plus the addition of an upgraded fuel cam profile lift.
The results are nothing short of phenomenal! 🚀 The base file put down a super strong 376bhp and 320ft-lb straight away. After a few quick revisions, we skyrocketed to a massive **419bhp and 342ft-lb**. The absolute best part? It’s making all this incredible power on **only 1.7 bar of boost!** 🤯
We took it off the dyno and onto the road for some real-world logging, and the car feels amazing. The power delivery is wonderfully aggressive, which perfectly suits my driving style. With just a tiny bit of final tweaking left to bring the boost in even earlier, this is going to be an absolutely fantastic turbo setup.
We are buzzing with these initial results and can’t wait to get it out on the track for some proper testing. Massive things to come—more updates to follow! 🏁🔥
