This solution is for those who want to get the achievement early in the game.
If you leave it for later, it's going to be really easy (with the right car and tons of ammo). You'll aso get this while going for the achievement for winning a death race at every location.
The earliest time bomb death runs are available in the north-east of the DRY GUSTIE
area of Jeet's territory.
This one is actually quite tricky. The problem is that there are enemies that keep spawning along the road. They are also much faster than you are so outrunning them is not an option.
The key to winning this is STAYING OFF THE ROAD.
KABOOM BUG is faster than the other car (MANCANNON), but it is carrying a fuel barrel which will explode if anyone rams into you or if you try to use nitrous! I exploded seconds after the race started, totally confused at what I need to do and again and again until I figured it out.
The race is a lot easier in the PINKY FINGER archangel car, but that becomes available later in the game.
So here is what you need to do:
1) Start the race with max shotgun ammo
2) As soon as the race starts, turn right
and then head straight towards the finish line
(you should see the icon ahead of you and a blue light in the sky above it). Keep off the road as much as possible.
3) When an enemy gets close to you, shoot them (press
) or outmaneuvre them (this will cost you time)
4) If you fail, retry the race. If you know you're losing, just bail out (press
) and then restart with
. If you restart, you should have full ammo again (if you started with full ammo in the first place)
Trophy time is 2:00 (needed for the achievement), legendary time (you get a token) is 1:37. I made it in 1:15 once I figured out the way to do this.
