Nice numbers, one of the reasons I think the aFe system is bunk

16hp & 11ftlbs with just the lid off ? Without the filter out there is more to get out of a CAI I'm not sure double that but large filter with a velocity stack affect could net more for sure. Great stock #'s :D

Wow....that really is a nice gain for just no air filter.

I installed the green filter tonight, it does seem to kick up the whine a notch or two.

Are these numbers SAE?

Interesting to see the air/fuel ratio differences -

Stock - Goes rich to lean
2500rpm -12.8;
3000rpm -13.0;
3500rpm -13.1;
3900rpm -13.1;


W/O air box top - Goes lean to rich
2500rpm -13.2;
3000rpm -12.9;
3500rpm -12.8;
3900rpm -12.75;

Peak power

Stock -
658.26 rwhp @ 6100rpm / 606.27 rwtq

W/O air box top
672.02 rwhp @ 6010rpm / 617.35 rwtq


Also interesting that the dyno cut out at 6,000rpm. Was the Hellcat in Sport mode? TC completely off and the ABS fuse pulled?
