In my Red RST i tried having a blast with a black XR2. Should have been no problem for a RS Turbo with 170ish bhp to see off a std looking E Reg XR. Then suddenly at 50mph he was catching me and at 80mph he was along side and at 100 we was past and pulling away

Later found out he runs a 1.9cvh fully worked head and lightened ballanced botton end and on twin 45's
