Thanks for the reference - I'll need to chew on this one for a while.
Your byline "'92 Civic Hatch - 10.9 @ 135 MPH, 100% streetcar (SFWD) spinning down the 1/8th VIDEO all at 6000feet elevation." is interesting.
I am getting ping with this ITR/JRSC combo at 5K ft elevation with a short ram and all else stock w/91 octane. The only way I can get it to stop is with the stock air box, which limits power. From the reference, I'm wondering if headers would help clear the cylinder of the unburned end gas and help eliminate. I'm not sure if pre-spark knock or post-spark knock.
