here is my write up from renntech.org

After much study I jumped in and did the X-51 airbox.

Cutting the hole was a major PITA. A couple of pointers get the X-51 upgrade TSB. Take off the painted portion of the Spoiler, it is only 4 screws and very easy to do. The cutout pattern in the TSB is a little small even if you print it with no margins. I enlarged it 102% and it worked fine.

Installing the Oil Fill pipe is also a major PITA. In addition to removing the ALternator which is difficult as previousily discussed I also removed the plenum which gave me more room to work. Removing and reinstalling this is easy as I had done before with the RSS Plenum.

As far as Adapters I bought the following from BoostController.com and after cutting it length with an exacto blade it worked perfectly;


Silicone Straight Hose, SHORT - 2 inch length #ASCSHS2-X

Size - 3.25 inch ID (add 5.00)

Color - Black

The dealer who sold me the parts also recommended the following; Hoover Vacuum belt for the Self Propelled WindTunnel is a perfect fit (part number 38528-035).

I also had to trim a little bit off the edge of the x-51 Boot to get it to fit correctly on the TB. I also had to push the clamp on in that same area with a screw driver.

It was a very challenging project but I am glad I did not only for the looks but the performance gains mentioned earlier.

RSS also has a modified TB which I added at the same time. They basically improved the aerodynamics by machining the entrance to more of a point for a venturi effect and machining the Shaft so air flows around it better.
