Sorry i was gone so long.... after all the family stuff..., and to be honest the naysayers or trolls... i kind of lost interest, but I think it only fair to give an update of my findings.....

Not to mention the sick sound that that thing makes hope it's running good and any advice you can give me will be greatly appreciated! Things to watch out for? Thanks again!
It runs GREAT... it has been amazing. Had 2 problems, the tune was bad when i got mine... but has been fixed. and i was only boosting 2.5psi but that was fixed with an adjustment on the blowoff... it is an amazing unit... more down below...

just has more zipp... more go... love it... cruses up grade perfect, down grade perfect.... but on level grade goes up and down ~2mph.... not perfect, but not a problem ether.

Thanks, David
was told the intercooler will be here at the end of year... already placed my order!!!!!

being it is a positive displacement twin screw unit,,, im been running it out here in the desert at 110*+ at not a problem...





ok, my take on the whole thing.... my son wanted to give me a race in his 2003 gmc truck with V8 5.3L vortec so, we were at a light...and we hit it.... well.... i could not beat him.. from 0-80 he had me by 1, yes..one, whole car length. I was surprised how well i did... but that was before i turned up the boost from 2.5psi to 4-5 psi..... i could beat him now!!!! i can chirp the tires around any corner, it jumps off the line like a medium size V8, passes on the freeway with a breeze, it got power... it is a pleasure to drive. very responsive, very linear, very well built. drove a new 2012 a few days ago... my 2010 will flat out smoke it.

thank you for all that supported me....

Thanks for the update. I do believe this will also be the kit I go with. Im sure that by the time I finish saving any updates needed should fixed and the intercooler will be out, from the sounds of things its not really needed, but I need to do my own research about that. Thanks again!!

Hey pauldana, thanks for the updates. Have you talked to them about the cruise or do you know if they are working on it. I am just so anal that I am afraid if it surges with the cruise that I will go insane. But I need something for power. Is the surge very noticeable? I like the price point on these s/c though.

No I have not talked to them about it as of yet.. I think I will call monday though, and give an update about it. noticeable????? yea... like i said +_2mph only when on level run... i would say 2 times more noticeable than that of a standard V8 in cruse on the hwy. but for me it is tolerable ...

I was so considering doing this supercharger, I love root style superchargers. But I came across a hemi and tranny for $1,000.00 on Craigslist and decided to go that route instead. Yet and still this is an awesome supercharger and thanks for all the information and updates on your project.

Default comparable acceleration to a new 3.6 or more like a 5.7

this kit was advertised as bringing up the power to equal the new 3.6 I would think that the supercharged 3.8 would kill the performance of a 3.6 since the low end torq should be way above.

I own a 2012 JKU and a supercharged 3.8
My 3.8 is a 2dr so weight is different. I have not drag raced the wife so I can only give a seat of the pants comparison but my 2007 SC JK pulls much harder through 3000-5000rpms. I know my 2007 can whip my 2012
