A few weeks ago I had this odd phenomenon that I'm trying to figure out. The car was giving kr at WOT when it was hot out, so I played with pulling the timing back to 17 from 19 on the gen II translator. It pulled strong with no knock for one pull and then started breaking up under WOT every time after that with no knock on my casper's gauge. This is pump gas plus slky with 24psi of boost. It seemed like the spark was getting blown out. I then tried adding fuel in the top end to no avail. This was just while I was out cruising around one day and did not have the laptop with me. I was also driving around with the dump open. Unfortunately my WBo2 is downstream far enough that I won't get a good reading on it with the dump open since it is at the bottom of the DP, so I did not bother to log it that way. So I finally got around to logging it with PL and my wbo2 tonight. It is a bit cooler out (81 vs 95) and I closed the dump this time, but did a few WOT blasts and all was good. Only 1 knock count and that was in the 2-3 shift. Timing is still at 17 and AFR was set fat over 5100 RPM from me screwing around. Below that was 10.8:1 and it went to 10.3:1 at the top end, but I pulled a little fuel out to set it back. It pulls strong now. Maybe I should just stay out of it over the summer, but what would cause the motor to break up at WOT with no knock readings? Is it possible it was running super lean with the dump open?
