i destroyed them when my car ran 250bhp on a t3 with lsd gearbox. i reckon if you both were rolling from say 30mph ull win BUT off the line the dc5 are good then hardly spin off the line mate they just grip up.. if you raced at pod its going to be a real tight race because i could guarantee he will have the edge off the line .. you may need more than 186bhp to close the gap AND get in front. however i gurantee if both cars were rolling fromn say 30 or 40mph you will win .. just race him on a queit dual carriage way somewhere dead mate.. my car now runs 32psi and i aint had a car even keep up ! its a zetec 2.1 t34 turbo tubular manifold etc quiaiffe atb diff
