no one makes a blower kit for the 5.7 JEEP/
now they do make them for other vehicles with the hemi but not jeep. and in the 6 years of the WK I can say I have never even seen one/ not saying someone has not adapted one just saying we have never seen one/
the LX hemis run about 6 PSI with the stock motor/ more than that the piston lands bust and thats it/
there are LX 5.7 BASED hemis running 10s. SRT8 6.1 running 10.0 with NOS only, no blowers, of course these are completely forged lower ends.
I would suggest checking out the other models that have the hemi and trying to work with the makers and get them to make somethuing for the jeep/
lxforums is a good place to start/ thats the home of MANY Boosted, BLOWN, and NOS Hemis
OH last thought/ the latest hemi with the VVT is causing some tuning issues/
