I just got back from Memphis Motorsports Park Test-N-Tune. I only made two passes tonight because I was helping a friend troubleshoot his '87 Turbo T. On my first pass, I heard some detonation and lifted just after the 1/8 mile. Upon reviewing the datalog, I saw a peak of 5 deg timing retard in 3rd gear with the converter locked. On the second pass, I bumped up the alky just a little, but left the timing at 25 degrees. (I was running around 23 lbs of boost.) The 1/8 mile was decent, a 7.96 @ 85 +, but around the 900 foot mark, the car popped through the intake and I lifted. Later, I stepped into it again and it felt great. On the datalog, I only saw 2 degrees retard at the top of 2nd gear. Anybody got an idea of what caused the pop? Was I being too aggressive with the tune?
It's still a stock turbo, stock valvespring, stock timing chain car with 160K miles on it. I guess it's on borrowed time at this level of tune :biggrin: I ran a 7.85 @ 86 + mph at the GS Nationals a couple of weeks ago, with a better sixty foot and better air. The engine still runs great.
