Cruised to an 11.51@116 with turbo 5.3 (video)
https://www.youtube.com/watch?v=8DCkwtT71E0
Running at 10psi, leaving on the footbrake with 3psi, the ol' turbo truck surprised me how easily it ran my goal time of 11.50. I'm signed up for Drag Week this fall, so I can't turn in a faster slip than that due to safety rules. The truck was super easy to steer and control, the launch was very smooth but pulled like a beast through the gears. The torque this little 5.3 makes on the boost is unreal. I had the shift points set at 5300, it was shifting at 5500 due to the inherent delay that's always present between the command and the actual shift. Not bad for a truck I've put 4000+ miles on since May! Here's a timeslip from an 11.48 pass: ![]() I'm re-doing the exhaust for a 4" electric cutout, hence the open downpipe in the video. It'll be nice and quiet (sometimes..muahhaha) next week.
