Ive tried taking about 4 degrees everywhere and it still does it. Tried spraying more meth, and last night put in 10 gallons of e85 so the tank was about 50/50 93/e95, still did it. Nominal spark advance is around 15 degrees, so nothing crazy. Also running range 8 plugs now...the truck runs too good for it to be real knock, but I am trying to avoid this again:


Mitch and I have been talking about this, watch the video again and listen right after the 2-3 shift at the end of the track. The truck sounds...weird...he thinks its misfiring, I think its just the wastegate dump, but its hard to tell. The log looks normal...

 

They make a lagoon out of the waterbox at the local track here, too. You'd think common sense would set in eventually.

 

I had a 2 counts on knock my last time out to right on the 2/3 shift. It's very rare for me, but it similar. I was at 185 ECT, 82 AIT, 15.5 timing, 11.8 air/fuel (out of fuel) so timing got pulled to 13.5 for 3rd gear.

Not sure what it is, not a good feeling to see it their, but since it's mid shift it just seems odd.

 

Oww and damn... Of course nice pass!

 

A friend of mine just emailed me this...

White turbo silverado at Holiday Beach Raceway - YouTube

Looks faster from the side

 

was it still bucking when you trapped???

 

I think it stopped around half track...I honestly dont remember it bucking when I was driving, but I have a lot of other things to concentrate on during that time.

 

I bet at that point you were thinking, Am I making 1000hp at this moment? Haha

 

Haha, it wouldnt matter anyway since its not 1/4 mile or on a dyno

 

1000 my ***. prove it.
