Whenever I go WOT in 3rd gear to try to log, I end up knocking badly as soon as timing drops from wherever it was when I started (mid 20s) down to 20 or 19.
It never fails that as soon as I hit 20, the knock kicks in. That usually happens around 3200rpm or so in 3rd gear.
I'm wondering what it should look like as soon as I go WOT and if it should be going down right away? And should I try to keep it above 20? Boost isn't all the way there yet either, I'm only around 10psi when the knock comes on and running really rich on the WBO2.
Base timing is 5* BTDC. MAFT running blow-thru with 3" GM. 550cc injectors. 37psi base fuel pressure, 255hp pump.
