    • Weistec Stage 3 supercharged W204 C63 AMG with 3.0 liter blower, built motor, and nitrous sets new M156 horsepower record with 929 wheel horsepower

      Some eye opening power here from a C63 AMG with a built engine, Weistec Stage 3 3.0 liter supercharger, Weistec tuning, and nitrous. The result with the laughing gas is 929 wheel horsepower on a dynojet. On the blower alone without the nitrous the result is 646 wheel horsepower. So, a gain of 283 wheel horsepower with the nitrous on top of the Stage 3 3.0 liter blower on a built motor. That is enough for a new wheel horsepower record.


      Simply incredible numbers. This car was built in collaboration with Racing Parts Solution that appears to be based out of Puerto Rico. They are planning to increase the boost from 11 psi for these dyno runs to 18 psi which on paper should put the car over 1000 whp with the nitrous.

      The C63 belongs to BenzBoost member @marioflex . Congratulations to all involved! Video below.

        Impressive numbers, I can not wait to see some track times. Any chances of you getting that monster over here to the mainland?

        Don't worry Earl, I am testing out something new in a week or two, so you and I will be back on top of the HP charts in a couple weeks....could you imagine if we sprayed ours lol? We have a definate advantage over everyone else by having two identical cars to develop and test with, I don"t see anyone catching us any time soon. Besides, as you very well know Earl, we still have a couple sizes of smaller pulleys we can bolt on that will bump us over 1100whp, just have to see if the tranny can cope.

        I don't think anyone doubts this HP record can and will be surpassed. As of now, it's a fantastic achievement.

        Quite the contrary it's very dangerous for cars that run 10's and lower. It's a deserted air base with very bad surface. There is only one international standard drag race track and it's called Tarlton Raceway at 5600ft+ elevation.
