Last weekend i ended up having to replace one of my UP pipes unexpectedly. While i was at it, I took the time to install Odwag's intake since it was sitting on my shelf. I thought it would be worth the right up since: (1) usually nobody installs just the intake without any other modifications; and (2) my truck has the fuel bowl and all other fuel lines in place (more on this later).
I do not have any dyno numbers, but I can give you a daily driving, seat of the pants, report.
Aside from the benefits already listed on Odawg's website, it is worth mentioning the increase in throttle response. This is a huge gain, the truck behaves more like NA motor now and relies a lot less on boost to breathe. just driving around town with nothing in tow, just a slight touch of the pedal and off you are.
Further, the minimal amount of turbo lag that was previously present with stock turbos is now almost completely gone. if you stand on the pedal of the line, it will almost instantly roast the tires.
The engine just flat out responds tremendously better from 0-50%. Which is where most of us do our driving.
Now the cons. It's without speaking that Odawg has spent tons of time and money designing the intake, but they come so close to having a flawless product and just drop the ball.
The casting job on the intake was very well done, I didn't notice any imperfections worth mentioning. However, the machining work left something to be desired. Most notably in the bosses where the IAT sensor and Manifold pressure sensor thread in. Both of these sensor utilize an SAE elastometric sealing surface (a threads with an o-ring). On both bosses, the o-ring groove was either completely missing or machined incorrectly. Had I noticed this before having been almost finished, I would have taken the intake back out. Further, several of the bolt holes had to be re-tapped because I could barely get the fasteners to thread in.
The next issue is, which is really not Odawg's fault. If you install the intake and intend to keep your stock fuel lines, you will have no place to fasten them back down. As the bolts, where previously attached, are no longer utilized on the new intake. What I chose to do was to cut the studs from the original intake and weld them to the top of the SAE plugs. This worked out great. I was still able to torque down the plugs and had a place to fasten the heat shields and fuel lines. Further, if you do not do as I did, your oil drain line from the HP turbo will have no place to fastened either.
Best of luck to everyone!
