take it to your local track.. and get some timed, proper runs under your belts
That way there are no excuses for the loser ! (hopefully your mate)
Plus you get to race for a good distance so the winner will be well and truly clear...
It's a good night out - you get to see plenty of good cars, and hopefully pick up a few driving skills out of it. Best of all - you'll be supporting
drag racing (not street racing), rather than supporting the beer'o'clock fund of your local government employees when you get done
as for your question - if they're both stockers, it will be much of a muchness - both auto? manual? - take as much weight as you can out of your car before you race him. You'll probably find that you'll get him on take off, and he'll catch up and pass further down the track.
