i have these results in another post, but I figure i would start a new thread because I dont think enough people were seeing it!

I guess i'm just a showoff like that..

Awesome gains!!!

What were the temps and humidity on both days?

I just checked the dyno, the temp that day was about 72 degrees, no reading on the humidity, but I can tell you it was a relatively low.

That is interesting, but why the difference in rpm's? The first run had the numbers at 5818, and the second had it at 639x. I am a noob when it comes to dyno charts and well anything that deals with dyno's. Please enlighten me.

That's particular RPM where they found the largest difference in in torque and horsepower.

They kinda cherry picked the torque difference if you ask me but nothing dishonest.

That's insane gains from an intake.

You're reading the chart incorrectly, Dynapack's display is a bit different. The chart on the left is the Torque, while the right side is the Horsepower. Run 1 is the numbers in the Yellow boxes and Red line, and run 2 is in the Green boxes and Green line. The largest gain for the Torque was found at 5818 RPM, and about 6393 RPM for Horsepower. Please excuse the 3 RPM difference between run 1 and 2 for the horsepower, the pointers are manuvered by a trackball mouse.

We did not "cherry pick" the gains. The high and low points of the gains were picked in the same fashion as they would have been if it were done on a dynojet. The point of this, honestly, is not just to tout peak horsepower, but rather to show that the gains are across the powerband, not just at the top.
