I own a stock 2018 f150 2.7, RCSB 2WD 3.73 rear. I've been pretty curious about how quick it is since I bought it, and a couple weeks ago I got my answer. I was making a beer run to start my evening helping a friend work on his house when I ran into a guy with a stock 04 Lightning. After a little bit of friendly talk we decided to do a couple pulls and see how the little 2.7 stood up. First one we agreed to a ~2k rpm launch, on the third honk I was off like a shot, the lightning never spun and I put about 4-5 lengths on him until I shut down at 100mph. Second race we agreed to an off idle launch, third honk and he pulls by a fender, a few moments later and we're nose to nose and by 100mph I'm probably 2-3 lengths ahead. I couldn't believe it, I thought for sure the L would hand me my ass, but all I heard was the supercharger whine while I pulled away. We pulled over to talk again and his truck is stock with about 150kmi. I'd like to get a few bolt-ons and a tune and see what she'll run.
