Default Hemi multi-displacement system - 12-21-2005 , 09:00 AM






Hey, guys!

Do you know -- from a technical standpoint -- why the SRT8 Hemis don't have
the cylinder shutoff feature? I assume that some modifications they were
making for more power required them to disable it?

The displacement increase and other modifications cut fuel economy, but with
lack of MDS the fuel economy takes a bigger hit. You might say if you want
an SRT8 then you don't care about fuel economy, but I'd still think they
would have left MDS active if they could have reasonably done so.

Thanks

Seem to recall reading that it wouldn't work properly with the SRT8 more
agressive camshaft.
