Fastest I ever went was in my Conquest TSI Turbo. 147. Once. On accident.

Was sorta playing a bit with this girl in her 'vette. 2 AM, Interstate in AL, started at like 100, she'd pull ahead a little, laugh, I'd pull a little ahead, laugh, etc ,etc. When I looked at the speedo, I was pushing 147 with pedal left to go. All I could think was, If I hit a deer at this speed, it's totally over. Never been over 110 since.
