It is best to use the Turbo Boost in even amounts while you roar around the track (depending on the course naturally). Use a bit extra boost at the start to pull in front of your competitor (especially if it's Bully Boy).
Try not to hit your opponent on a corner as you will most likely come off as well. If you must hit him, try not to run into him - best to nudge him from the side. A point that people don't think about is when you've just taken a jump take your finger off the fire button. It just wastes valuable boost units when the adrenaline pumping.
Fairly standard high-rise racing up to the stones. Hit them at about 140 and use the boost if necessary on the last few.
Accelerate to top speed with full boost at the start to give you enough speed to jump the pillar in the middle. You can bounce your way over the pillar if you're speed isn't quite top-whack (causing minor damage). However there's a fair chance that you'll slide afterwards - if so bye, bye car!
Don't go too fast as you pass the start line otherwise you'll miss the first corner - around the 150 mark should do it. It's pretty obvious but the actual Coaster is THE place for picking up speed.
Hit the jump at around 150.
DON'T hit the bridge while it is up - Just wait until it's on the way down before attempting it (a little earlier if you're at the bottom with the engine idling).
Don't go too fast on the first left turn or you'll go flying over the next corner. After that you may as well go for it. This is one of the few courses where it pays to go like mad (baring the first turns, of course). If you reach top speed as you reach the jump then you should (in theory) touch down neatly on the slope following it.
A good speed is needed at the start for the first two 'small' ramps; about 170 is best. You will need to be travelling at round 210 for the big jump itself.
It may look easy but it sure as anything isn't, if you go too fast. If you find yourself going over it at top speed you may well float over and smack into the corner after the hump. Only use boost where it is a necessity (at the start / finish mainly).
At first, stay behind and follow him, watch out for his characteristics and if you get a chance, boost directly behind him until he blocks your vision (some knowledge of the track will help) then pull left then right and he's outta your way. Save this till the end.
The same rules as apply to the Whizz Kid. Don't overtake till nearly the end of the race.
In my opinion he's the hardest. If you get to the 1st Division then you should have a lot of skill. All you do is battle, you'll have to ram him out of your way if you can make it to the top.
The most annoying thing about him is the way he wheelies just in front of you when you get near, especially at the start. Take him on the jump; speed up and jump over the big guy.
The hardest of the lower order drivers but if you're good and know the track you can boost in on the bends and take him on the outside. It takes cool nerves and a joystick of steel.
