I have been running my ram air since 11/99. Using the Moroso foam at 3-4 inches thick with a tight seal it should not move. But now you guys have me thinking about highway effects. Could it be the carb pull is somewhat offset by the rammed air ? I will keep an eye on mine and surely use an aluminum reinforcement on both inner and outer edges. Thanks !
Dalola....I had the same reaction as you when I put my ram air pan on ! The snappier throttle on a roll was my first discovery. If you fatten jets, I found just 1-2 up in the rear did the trick for me. Holley go +1.. BG go +2. MAYBE. That left me with a ten point spread between front/rear which BG advised was fine. It maintained the primary, around town AF mixture, but provided just a bit more fuel when I laid into it and began gaining momentum. One jet in rear may do it. BUT our motors may have all the fuel they need if jetted right. It is unburned fuel we may lose at high rpm caused by restrictive air flow that the motor now may be able to burn . I am no expert but I think the air moves through the intake cooler and faster for a more "efficient" burn. Therefore you may need no jetting or just one jet in the rear. My biggest gain was in the 5000-6000 range in 3rd/4th. I could hear and see the difference in the tach. I don't even look during 1st/2nd...too much going on.
