x'ed,

You are probably correct in a way. The AWD dyno probably is expecting drive power at BOTH sets of rollers even though they are connected by a belt system.

That said, this was the only way round the fact that the Crossfire seems to lack the 'dyno mode' that the SLK32 has.

If we 'fudge' the numbers and add that 30 whp back in, then yes, you are correct it's about what is expected and what another SRT6 owner dynoed at over in the UK.

You can see his numbers here. My only question to ichon is what did they do to get around the lack of 'dyno' mode besides being on an AWD dyno?
