Crash Team Racing Nitro-Fueled - Unstoppable Trophy / Achievement Guide - Sustain your boost for a whole lap. [Silver]

By combining Power-Slide Turbo, Turbo-Pads and Turbo-Power Ups you will have to keep your exhaust on fire for a whole lap. This might be tricky but considering you want to beat Oxide Time Trials, this should come naturally at some point. The easiest track for it is Coco Park since you have a lot of space for triple-boosts and some turbo pads in between.

Most important is the Slide-Boost. You initiate a Slide-Boost by drifting (R1 + LEFT STICK) and then press L1 when you see black smoke coming from your exhaust, or when the boost bar in bottom right turns orange. You can string 3 slide-boosts together per drift, doing 3 in a row results in one big boost, which you must do repeatedly to maintain your boost. After 3 boosts, jump with R1 to initiate a new slide and you can do 3 new boosts again.
