[W126 Coupe] went to dyno

[airedale at sbcglobal.net]

I am curious the year & model of W126 you have please? I have a book I bought through the MBCOA that states the US version 560 is actually more horsepower than the 238 or so that is advertised.
Thanks,
John

  Well finally got to a dynojet, interesting results...

  RWHP= 256.1
  RWTQ= 298.22

  so using standard conversions for drive train power loss gives me:

  HP= 299.6 -> 309.9
  TQ= 348.9 -> 360.8

  Note, this was with oversize (heavy) rims, and reinforced clutches in the transmission. So that means my drivetrain losses may have been higher or lower compared to normal calculations.

  The projected power figures almost exactly match the amg 117 5.6 SOHC engine with tubular headers (but i am running euro 4 peice cast manifold still). so....does anyone know what was renntech's advertised hp and torque for the 6.0? What other modifications did AMG do to the 5.6 SOHC besides cams and headers?
