the 30 psi was a fluke but it wasnt knocking so i kept the pedal down
02s were way low but they arent reliable anyway as Ive recorded 750mv climb to 760mv through third on DS and WB showed 11.5 a/f and steady drop to 9.5 a/f
two weeks ago car had steady knock under boost and found the stock cam lost most of #5 exhuast lobe so in went the edelbrock and lifter ,and turned same times as two weeks prior of 11.6 113with the TE44 std wastegate 24-25psi
I had a light smoke issue afterthe cam so i pulled the te44 which was already approaching 115and would have sent me home early for no cage on the next pass , so I tossed on the stocker and couldnt get the boost i wanted from it in third , with HD wastegate it would hit 28 on shift then drop to 25 or less and car was smoking more than ever so i did the valve seals , still had some smoke so pulled the intake again for a reseal and found some in out play in the stocker so on went the 49 , smoke problem cleared up so off to the track i went with the same HD wastegate and BSTC . first pass was supposed to be a soft run to get the data to see what direction to go in. Not wanting the boost to be high i set the gain down from 2:00 to 10:00 and i flipped the #4 dip switch to reduce from 1-2 ,( rear dial was set to 80% clockwise ) which should have lowered third boost , should have been about 23# or so since it was 20# with bstc off, i run the ecm boost wire disconnected to prevent the 100% signal when you turn unit off, wastegate rod set minimal pull on to hold puck.
chip was set at base fuel which for me already had 10%WOT fuel above std 23# 23/20* alky chip , 27/26/22 timing chip setting (128/140/134)
i I was the 4th car to pass down the track so little to no water at the line sun was out and temps were close to 67* the launch stuck (18psi in tires) , 25# 1st , 25# 2nd then third hit and boost gauge went full so i reached over turned the BSTC gain knob down which should have reduced third in relation to the gain but still had what looked like steady 29-30 psi .should have flipped the switch to off but i only had had a hints of KR 2.0 soon as third hit which i usually get knock there anyway due to the converter being locked and the sudden drop in rpm of nearly 1600 rpm, went through traps at 5750 inj duty 89.7% on the 50# injectors , alky was set to 12:00 and apparently did its job (thanks julio!!).
if this run had been on race gas i would be picking up parts
looks like the turbo took a dump though as the next burnout i felt what i thought was the tires taking a firm bite into the track surface midway through the burnout , went to launch and boost wasnt coming up ,thought the converter was toast (sounded like the sprag went like last time) or trans failure , had to take a drive down the 1320 at 50mph 21.94 heard what sounded like sraping and seemed to be from intake more so than from under car , couldnt really be sure because i had to keep windows up while on the track.
quick check in pits and found three of the compressor blades made contact with the housing and rolled over the edges , pulled it apart this morning and shaft is in one peice and spins but one side of the wheel is worn down , still not sure what went wrong so stocker is back on , quick brake boost and she went right to 15psi so Im back in business make slicks out of MT radials
