MBH Motorsports releases downpipes for the 63 AMG cars equipped with the M157 Twin Turbo V8 and claims huge gains
Here are the new downpipes for the M157 Twin Turbo V8 from MBH Motorsports. MBH partnered with Evotech regarding a tune that compliments their downpipes on the motor. The result is large gains but the graph does not show the peak figure so some slight estimation is necessary. It would appear that with a tune the downpipes are claimed to offer a gain of almost 50 wheel horsepower on top of just a tuned M157 car. That at first impression seems to be somewhat high.
The torque curve with the downpipes appears to be fairly radically changed well. For whatever reason, the turbos appear to spool slightly later with the downpipes rather than slightly earlier. The shape of the curve is also different from 3000-4500 rpm or so. The torque gains just appear to be huge.
Pricing has not been released but hopefully we can all get some more dynos of these downpipes on another dyno, possibly a dynojet to better put them in context. Additionally, it would be nice to see the difference of the downpipes make alone without a tune.
