Easy Win:
When you have a drifter on you crew, set them active. Then in the race get in the air-stream and and use NOS. They have to keep a certain distance between them and you, so if you go faster they will to. I used this in speedbreaker races and won every time. Note: this is good to use with unlimited NOS and unlimited crew charge

More money per race:
You must have Samson in your crew for this to work. Set Samson as active, as he will give you 10 extra cash each race. Keep Neville in the crew but do not set him active. Now for each race you will get 10 extra cash per race AND 200 extra cash from Neville. For example, after one race you would normally get 18,000. But because of Samson and Neville you get an extra 200 and an extra 1,800 10 of 18,000. So you get 20,000 instead of the normal 18,000.
