2012 Hemi Cherokee Air Intake and Performance Chip

Anyone hear of Engine performance chips - electric super charger 2.5 PSI air intake unit? does it work? -- also they claims to have the X3 performance chip with O2 sensor, they claim some big gains for both -- BS or true?

Re: 2012 Hemi Cherokee Air Intake and Performance Chip

That would be the first I've heard of anyone delivering a real chip for the WK2 with a Hemi. Electric supercharger? Again, I've read about them, but haven't seen anything other than one-off fabrications. Do you have a webpage you can direct us to?

Re: 2012 Hemi Cherokee Air Intake and Performance Chip

They claim a 20% HP bump from just their "chip" . . . pretty much a total fantasy for a normally-aspirated engine. The "supercharger" looks like a turbine/fan that's placed in the intake snorkel. If anything, this looks like something that would disrupt airflow. It is most definitely not a true supercharger.

Run away! Run away!

Re: 2012 Hemi Cherokee Air Intake and Performance Chip

see a couple of faults with this device.
1 no boost control, speed control. Low revs=high boost, high revs=no boost more likely a restriction.
2 impeller clearance is too great from the sides to make any boost.

Re: 2012 Hemi Cherokee Air Intake and Performance Chip

If installing a hair dryer as a supercharger worked, a few manufacturers might do it. Too bad it doesn't. Total BS.
