Hey guys, been away for a while. I wanted to update you all just so you know what ended up happening.

Sent the Jeep up to Arrington Performance in Virginia. She went up there with 407 RWHP. I had ARH exhaust and headers, CAI, Johan tune, BBK TB. So I was happy with the results.

Was told the jeep would take about a week or so to finish. I thought this was a little optimistic but was happy with that timeline. A week went by and emails would take a week to get responded to and calls would just ring and ring…..
*Fast forward*
A month and almost 20k later I FINALLY get the Jeep back. In that month we decided to do the maggy blower, forged pistons, and viking tranny.

Anyway, the Jeep gets back, I am so excited. I notice the push start button is in my cup holder. I put it back and push it. it doesn't turn. The engine cranks up and all but doesn't turn over. It does this until I have to take the button out to stop it from endlessly trying. I put the key in and it starts right up.
At this point I am kinda scared but anxious to get the car on the road and see what it does. I am light-footed with it until I get to a stop light at the exit of my neighborhood. Turns green, I gun it….I am completely surprised….at the lack of power. I honestly doesn't feel any different. I thought maybe thats because I was driving a M3 while the jeep was absent. So I drive around and try to get used to the Jeep again.

Later that night I take it to do a little photo shoot. While maneuvering the car around I put it into reverse and it stalls out. Super weird stuff. At that point I head home as it stalls at two stop lights on the way.

I talk to the guy who set up my build and he tells me its my throttle body and I just need to drive it more. The next night I am out with my girlfriend. As I drop her off I notice what looks like smoke at a stoplight but my engine temps were fine so I thought it was my exhaust hitting the cold air and going past my car. I get home, shut the car down and here a loud hissing sound. Pop the hood and there is coolant EVERYWHERE. Turns out my water pump was bad and it dripped coolant onto my belts which sprayed it everywhere. Jeep pumps were on national backorder and we could not find one anywhere. After spending a week looking at my supercharger paperweight we finally get a pump and fix the problem.

I posted on the jeepsrt forums and got flamed for being blunt and disappointed at the quality of this job. Arrington is supposed to be a top notch builder and I got anything but top notch service. If you told me that they did not test drive my car, I would not be surprised. Because if they put any effort into really properly tuning the car they would realize it was having these little problems.


ANYWAYS, after a week or two of being pissed and with my car limping I find a nice car for sale and turns out that they'll take my jeep. I head up, sign papers, and drive off with a GTR. LOL. I am really disappointed in the build. I love the jeep community and the jeeps themselves. But idk, I guess thats how it goes. I am sure that I could've spent more time and money to get the car exactly right, but I just gave up on it.

Heres the before dyno of my jeep.


and the after dyno….



So pretty much I payed 20 grand to get a 83 boost in torque and 95 in rwhp. For 20k? Worth it? Hell no.

ADVICE TO ALL 2012-13 OWNERS. If you are looking to do ANY expensive build on your jeep. Sell it, but a 2014 and mod that. They are so much faster than our rigs. Don't throw money at your 12-13.

Anyways, just wanted to let everyone know what happened. Didn't wanna ball out without telling you all what happened. Heres some pics of everything lol.





Heres my switzer p600 GTR. Also has springs and AMS CF hood and rear wing…

Stories like this are what makes me hesitant of ever doing anything with my Jeep.

Frankly I thought the 20k for the return was worth it, that's RWP so you're getting 100+ at the crank. The fact that you had issues is the real problem though, they delivered a broken vehicle to you. There should be rules about this type of behavior, frankly you should get your money back as well as expenses to return the Jeep to "normal" functionality.

ok.. so lemme guess they F'd up the installation and the tune was crap

here in the UAE a garage managed to create a custom turbo kit that gurantee's 200+hp on ur SRT at daily driving boost.

it put good numbers on his 13

i have a 12 that has been mildly modified and custom tuned
im making somewhere around 440 to 450's awhp

im sorry to whoever gave u that install or did this to ur car cuz he surely didnt know what he was doing..

90 hp is a joke for a supercharger

gratz on the nissan gtr

I agree with him because:
1. the 12-13 are going to drop in value like a rock, they already are. People will want the 14-16 models going forward. You're just inflating your loss, contain the bleeding.
2. Going to take near $20k to do serious power. The 6.4L Hemi is designed in a way, along with the ECU program, where it's tough to extract high power especially through boost.
3. $65k truck plus $20k in mods = $85k (average)? Unless you are rolling in cash, why? And lets not answer with the "why not, people put "X" into "Y" and it's not worth it. We're talking reality here, and an across the board modding for the whole WK2 SRT8 community....it's just ridiculous to think many owners in the group want to spend that much. Obviously any performance vehicle is going to have a few who go all out, but I think when a question like this comes up many are looking for an answer that touches across all of us owners ideas. Shop owners can do it because they save a lot through their own labor, wholesale parts prices, tuning abilities, and in house fabrication. If you've got $85k to drop, there are countless other beasts you can buy new/used or build that are more worth it than a Jeep SRT8. IMO, enjoy the WK2 SRT8 for what it offers and focus on holding the free and clear title in your hand with maybe slight mods here and there.

FYI - just checked the rules in NSW Australia and it looks like bolting such stuff on down here is not legal without a while lot of engineers reports, emission testing etc etc. Might still chat to a shop and see what it is like in "reality"...
