Turbo 5.3 ms3x fell on its face staging? Kind of scratching my head and need others input and advice. So last weekend was second time ive had car at the strip after building it. Its a 5.3 s480 th400 ptc converter ms3x truck coils Twin aem380 bosch 210 etc etc
So out of my previous 7 passes or so i didnt have any issues. On my past lass went to burnout and it seemed to hesitate and lose power. So i went to go stage the car, hit the tb and started spooling. At about 3200rpm car just fell on its face no popping that i noticed just fell down to about 2k rpm. I slowly rolled off the line and about 100ft out punched it and it made good power and revved cleanly. Logs show good fuel, and crank signal. Tune was fine. So i though maybe tranny was screwed up, however it shifts just fine and i dropped the pan and all is well.
Anyone have any idea? Has new plugs, wires, Fuel cell was full, it never went lean. My only guess is maybe my coil packs lost power intermittently from using chinese relay?
Motor sounds good... I dont know what to think. Gonna fill tranny and try to replicate it on street i guess. Any guesses are welcome. Or anybody thats wants to see a log let me know.
