This morning I ran some cold comparison tests for the K&N Filter in the Spectre CAI.<\/p>\n

I changed my test method for these runs — same test route, but instead of starting from a stop, I started from a roll with the transmission manually selected to 2nd gear.\u00a0 My thinking was that this would be less stress on the tires\/drivetrain, and give better low rpm torque readings.<\/p>\n

\"kn<\/a><\/p>\n

The results are not what I expected.\u00a0 We were looking for 376-380 whp so that part seems in range, with one runs at 384-388 whp.\u00a0 The one run at 350 whp is odd.\u00a0 The torque readings in general don’t seem to take the form one would expect.<\/p>\n

\"kn<\/a><\/p>\n

On the ‘green’ run in Virtual Dyno, I didn’t flip the transmission to auto-shift, so it redlined in 2nd gear getting to 6700+ rpm where the fuel cutoff is set.<\/p>\n

Here is a similar graph with a previous 2nd gear sliced out of a 0-60 run compared with one of the runs from today:<\/p>\n

\"kn<\/a><\/p>\n

Red is today’s test; blue is a recent test in cool air with the Spectre filter in.\u00a0 Today’s run appears to show much higher low end torque, and lower high end HP peak.<\/p>\n

Next I will take the K&N filter off, check the installation, and re-install to see if there is something physical I am missing here.\u00a0 Then I will re-oil the now cleaned Spectre and re-install it for testing.<\/p>\n","protected":false},"excerpt":{"rendered":"
