ive recently had my mk1 turbo’d
she’s currently just under 300lbs of torque. On stock internals just a better clutch to deal with the extra power
speaking with a friend who has basically the same setup. Td04 and me221, but his is at 200lbs if torque. apparently 300lb is rod bending amounts? Not sure how true that is or if his mapping was limited due to not having a performance clutch.
