E90 M3 Dyno Runs

[Andy1gg]

Went to EAS today for some Dyno runs. First 2 runs car had the following mods Eventuri intake, evolve xpipe with primary cats delete secondary high flow 200 cell cats, Haimus racing plenum and Alpine stage 2 map tune. Best run was 357 horsepower then they installed macht schnell pulleys did 2 more runs and best numbers went up to 378 horsepower. Not sure if the 21 horsepower gains were from the pulleys but for all the people who think there are no power to be had from pulleys this is proof there definitely is overall I couldn't be happier. For only $300 this is by far the best bang for your buck mod. To confirm these gains I had Dyno my car before with the same mods before the pulleys and my best numbers was 359 horsepower. Below is link to my Dyno runs

Did you by any chance do any runs with all the same mods, only with the stock plenum?

… to see if/what the gains are from the Haimus plenum?

Actually my first Dyno session last year with 359 horsepower was minus the Haimus plenum and pulleys

So, the Haimus lost 2 hp?

How about torque?

Not sure if it lost power because you have to take in consideration it was at another Dyno on a different date time weather and fuel come into play for different numbers. Here's pic of my last year Dyno sheet with same mods minus the Haimus racing plenum and pulleys
