That mission was a pain, i had to switch the driving options from hardcore back to sport when i was just getting used to hardcore.. It was damn near impossible on hardcore. After trying afew times with the time running out each try, i ended up catching him when the plane is flying overhead pretty early in the chase..
What you want to do is line up your car behind his and use the nitrous to catch up, but dont ram the back of the car, pull along side it and easily push into the side of their ride so your making constant contact, their health will drop almost instantly and you've won.
