All the old parts off the TB and heads...this is a good time to check the operation of all the parts that move and lubricate the cables...

This one shows the powerpacc vents and banjo type bolts, with washers, ready to install.  The 06 model requires two of the nylon washers on each side of the vent...

PowerPacc vents bolted up to the heads, and torqued to 12fp..

This shows how the "plumbing" works for the vents to get the mist (if any) back into the intake.  This is not absolutely necessary, but I was afraid at high speeds/RPM there might be some mist which would be vented where I didn't want it to be.  The Nylon 90 degree nipples must be positioned correctly to get everything out of the way for the next step...

The above photo also shows the back of the plate well..

Backplate is then bolted to the TB with three socket head allens, after the gasket is put between the backplate and TB, of course.  New gasket is in the kit...also shows the button head bolts that go into the slotted holes in the backplate and into the powerpacc vent banjo bolts....

This is a shot of the venturi installed into the backplate/TB...there is an O ring which is shown better in the next photo...oil the O ring up, and the venturi is a machined fit which requires pressing in with the heel of your hand, or a rubber mallet, if necessary.  There are slots milled into the backplate for removal, if ever necessary...just pry it back out of the backplate.  It is a very good fit...

Closer shot of the O ring seal and how smooth and well machined the venturi is...

Filter in place, ready for the top plate to be bolted on with button heads...a drop of Blue loctite is recommended on the buttonheads.  The filter is shaped slightly different, and is wider by about 1/2 an inch...

Cover gets bolted back on with the center bolt, per normal...a spacer is provided for the backside to hold the cover off the backplate...I also reused the thick gasket I had on the old system for some additional support, but it really is not necessary...but, I had it, and it "seals" the cover, but mostly is useful to keep the cover from rotating.

Screamin' Eagle plate screwed back on...done!!!

The principle behind the powervents is to allow pressure to escape the crankcase while not allowing new air to enter on the downstroke, as the vents are one way valves...seems to work.  Will have to see if there are any gains in power...I do know that my motor needed more air, as it was proven to me by the tuner/mechanic at the small shop I had the tune done...he claims that the normal size filter is marginal in allowing enough air for our 103's to fully breathe, particularly when installing the TD RH's...

I'll let you know next week about how it feels, and whether I can tell any difference in HP/TQ...they claim 2 or 3 on each side with this system because of the venturi design and powervents, plus the filter being larger in surface area.

Still trying to get them d@mn radio bolts on, huh Terry?!?   [smiley=huepfenlol2.gif]

PowerPacc looks GREAT!  Awesome photos!  Can't wait to read what your impressions are once you get a chance to take a scoot!
