There's a guy on my PT Cruiser forum who heavily built the factory turbo engine in his PT GT and has run a high 11 second 1/4 mile with it. That run was with 430WHP and NO nitrous. And it's his daily driver. With a nitrous spray he dyno'd at 599WHP and 667lb-ft on stock internals. That's a hell of a little motor!

He has since swapped engines to a 2.6L stroker and is shooting for well over 500WHP without spray, 800WHP with the juice.
