So I broke out the old U tube monometer, and decided to do a few tests last night.
To get a feel for what the old intake was doing.
Now I would like to point out that I have no grill. So airflow to the stock intake was greatly increased.
The trials were accelerating through 60 and crusing (holding speed) at 60 same for 80mph. I also did a peak intake vacume measurement which usually came around in 1st gear at 5k rpm (coincidentily peak power so it makes some sense). All measurements are in in H20.
1st trial stock
peak -6
through 60 -5
crusin 60 0
though 80 -3
crusin 80 +.5
2nd trial NO filter
peak -3
through 60 -2
crusin 60 +.5
though 80 -1.5
crusin 80 +.5
3rd trial NO snorkle
peak -5.5
through 60 -4
crusin 60 0
though 80 -3
crusin 80 0
4th trial NO snorkle, No Resonator
peak -3.75
through 60 -3.5
crusin 60 +.25
though 80 -2.5
crusin 80 +0.5
5th trial NO snorkle, No resonator, Bottom of the airbox removed
THe filter was duct taped on to the top of the air box.
peak -3
through 60 -2.5
crusin 60 +.25
though 80 -2
crusin 80 +.5
Looks like the car runs best with no filter. And there's a pressure build up in the engine bay.
Im staying stock though because it gets cold air that way.
