Welcome to i-club where everyone thinks an RS can do 0-60 in 8+seconds.
Seriously thats pretty terrible. If you can only get a 2000+ RS to run 8s you need to get a little meaner
On one of our clocking days stock i was running 7.4 and 7.5 consistently. Added a catback and intake and pulled 7.1 and 7.2s.
VR6 is just plain quicker but not too terribly much quicker.
RS should hang around till about 50 or so
