Another batch of Xona Rotor turbos delivered today from Aet Turbos, all these are X2C small frame, despite their small size there's over 1700bhp of dyno proven power sat in this little collection! 💪

Evo 8 mapped this morning, after initially getting strong results at 1.2bar, the power returns when going to 1.8bar were poor, after a quick check round we found the existing Jasma exhaust had 2.25 inch backbox internals 🤦♂️
After a quick chat with the customer off came the old system and on went a G-R Performance 3" cat pipe and catback, and back in the dyno.
End result 400.3bhp and one extremely happy customer, with a proper Evo exhaust note as a bonus.
After a full build over the winter, mapping is nearing completion on Ryan Barkers Renault Megane.
Equipped with a Honda K24 engine, with a Xona Rotor X2C turbo kit, and a VW DQ250 DSG gearbox, all controlled via an ECUmaster PMU24DL and Syvecs S7 Plus ECU 🔥💪🔥
