New Best ET & MPH !!!
Thanks to Bison for some tips on locking my converter !!! Thanks to Dr. Carl for some tuning tips on my last 2 passes helping me get where I wanted safely Thanks to my buddy D-Ham for convincing me to turn it up and give it one more try...more then once
I made 6 passes all together...1st pass wanted to see how the cold air would affect my boost...forgot to hit the record button on the PL so I just cruised on the top 11.71 @ 110.60 1.67 60'
I installed a switch to lock my converter in 3rd...plan was around 90-105.
2nd pass turned out the switch was in the wrong position so the converter locked in 2nd and then I unlocked it in 3rd on the top end :redface: still ended up beating my previous best ET & MPH 11.44 @ 117.34 1.66 60' ...I did not get booted :biggrin:
next 4 passes locked the converter correctly in 3rd @ 90-105 mph but one when I forgot to flip the switch. Each pass improved...turned the boost up 1# each of the last 3 passes from 23/24 to 26+...also added 1/2 turn on the regulator on the last pass @ 26+ psi boost. The previous pass showed a 760O2 on the SM recall on the top end so added a little fuel just to be safe. Virtually no knock [/B](thanks to Razor & Alky Control)[/B] other then a little blip when I locked the converter 1.2-1.8 for maybe 1.5 sec. My O2's were good all day 780-790's...dipped into the 760's-780...last pass O2's were 770-790.
