Ram air pics
Here are some pics that will help explain what I was refering to in a previous post.
The only thing I did different from the standard ram air mod is remove the lip from each side of the hump on the black underpan. The hump is the part sticking up through the hood. If you look at a stock underpan you will see the lip I'm talking about. It blocks the air flow from getting around each side of the hump. Look at the upper left corner of photo #4. There would normaly be a lip about 1/2" tall running down each side of the deflecter that is sticking up through the hood. It blocks most of the open area you now see in the photo between the deflecter and the hood. You can see where I cut it and used a file to smooth it out. You don't want air going over the top of the hump because it flows between the hood and the plastic piece that sits on top of the hood and exits back over the gauge cluster. (A confirmation of JWilson's findings) Air going around the side of the hump flows to the holes cut in the back side of the underpan and to the front air vents. I also have some pics of the access cover that sits under the glove box. I filled it full of holes. This is a great place to get more air inside the hull. For you guys running a Riva or homemade intake, this mod should help because the position of the intake inlet should be very close to the access cover. You could hear it sucking air in when you hit the throttle. I can see why R&D made a filter for this spot and why Riva put the inlet for it's pro intake there.
The temp was 92 today and I ran 67.9. The fresh air mods along with removing the rear vents and hoses really wakes this bad boy up. All my mods have been done this summer and gave me some gain in top speed. Mid 66's has been as fast as I've gone in the heat. To be able to go almost 68 in the heat is the best I have run all summer. I also hit 7860 rpm's today. I haven't seen those rpm's since April. The fresh air mods also gave it better punch on top end. Another thing I noticed, I went almost as fast on my last run as I did on my first.

Thanks for the pics. Did you remove the front hoses breather hoses like you did with the rear?
Your 67.8 was that low on fuel or was that full of gas? Everyone records their speeds at different times so I just want to be sure.

I had 3-4 bars of fuel when I made most of my runs.
On the front I cut down the length of the hoses so they end just above the air horn on the intake. The R-rated intake goes all the way up almost under the front vents.
I also cut the front side of the lip on the vents. Some of the air that goes over the front vents should be sucked in by the drilled access cover under the glove box.

What has to be taken off to get to the plate under the glove box?
