Last day before I put my 03 Centennial Edition GT away for the winter... and I ALMOST blew my motor!!!
I'm running a Vortech V2SQ - SI trim, 42 lb injectors, twin SVT 255 lph Fuel pumps and dual hotwiring to the pumps, Procharger intercooled, 3.12" vortech pulley, AFM powerpipe, and a 95mm Sniper MAF... Running 91 octane (highest we can get here) and a conservative tune.
I was on my way to the gas station to add fuel stabilizer and fill up... and decided to give her a rip down an on ramp and onto the highway... I had less than 1/4 of a tank... BIG MISTAKE!!
My twin 255s weren't getting enough gas under hard accelleration at WOT and she went lean and detonated.
I limped back to my tuner who removed the plugs - 6 of the 8 plugs had melted the tip off!! We put a videoscope down all 8 cylinders and all is clear inside - no piston damage.
A fresh set of NGK TR6's and a full tank of gas and all is well. I was some relieved she came back to life with no permanent damage.
Man I am lucky that didn't end VERY badly.
From now on - I will consider 1/4 of a tank as bone empty - I do not want to ever go lean like that again.
