To actually pull on a good 330bhp cossie you'd need a good 350bhp in an RST. Even that said once up to 130mph it would be very close.

Bare in mind a proper 330bhp 2wd cossie will do 0 - 60 in sub 5, 0 - 100 in 11secs and top out at 165mph. As you can see to out accelerate this in an RST you'd nead a VERY fast RST!!!
