This is a dyno run of my SLK 230 with an ASP Overdrive pulley and K&N Filter. Temperature was 100 degrees. Dead serious.
Best run was 160.1 hp to the wheels on a Dyno Dynamics Dyno. Assuming 12% lower numbers vs. Dynojet leads to around 179.3 to the wheels. I would've probably gotten a better figure if it wasn't so hot. Next video shows the difference after a tune by OE Tuning.
