Unfortunately I still have not shipped any of the test units. I've been fiddling with the heat shield/box trying to fix a fitment issue. I have the first test intake complete and ready to ship, I'm just waiting on the lids at the moment, and then it's off for testing!
I have made one change to the silicone intake tube to test out... I made the tube longer than it needs to be to connect to the velocity stack / filter clamp (VS/FC) piece. Doing so allowed me to make a cut out around the MAF mount, so that the tube would slide onto the tubular section of the VS/FC piece almost up to the transition... So not only will the inside of the airbox be insulated with silicone sheeting, almost the entire portion of the tubular VS/FC piece will also be covered on the outside from the 1/4" thick silicone intake tube doubling as it's insulation. Hopefully this will ensure super low IAT vs Ambient temps, however more testing must be done to see... How low can you go???
Just a hurry up and wait game now.
