So I finished up the turbo build, got the car out and started dialing in the tune on low boost (2.5-3lbs). It’s definitely not easy but I was getting it sorted out. On the way to my test spot the car wasn’t idling great and that should’ve been an indicator but messing with virtual torque previous to this I thought I had just screwed up. Made two 1/8 mi hits and on the second hit the engine locked up and wouldn’t restart. Tore the engine down and I spun #7 so bad it actually cracked the journal on the crank and it is now junk. Looking back at everything and why it went wrong, I did have some kr through my tuning process but not on the 1/8 mi hits. What I believe is my issue is the turbo scavenge pump return. I ran it to the stock catch can return port on the oil pan. I thought I was being slick and had seen other people do it. Well the tube inside the pan goes all the way to the bottom and faces the oil pump pick up. Gravity draining to this port wouldn’t be bad in its current configuration but pressurized oil and air being pushed through it I believe i aerated the oil causing the bearing to spin. LT1/L86 cranks are unavailable for who knows how long. I ended up ordering an L8T crank from scoggin Dickey and a drop in je/tsp h beam combo from Texas speed to get me back going. Hopefully you guys won’t crucify me too bad but I’m sharing this to hopefully help some one attempting something similar in the future.
