MOD COST: $90 from www.buggypartsnw.com
MOD DIFFICULTY:
Easy. If you can change your oil, you can probably change your variator.
SPECIAL TOOLS: Impact wrench is required to remove the variator nut.
MOD BENCHMARK: Noticeable increase in initial acceleration, as well as higher top end.
NEXT STEP: Clutch springs would be a good next step.
The upgrade of the variator is probably one of the biggest bangs for your buck that you can do early on in your upgrades.
The Dr Pulley variator offers both a steeper ramp path as well as a longer total ramp length than the stock variator. So you might ask what this means to you? I'll explain.
as you engage the throttle the variator plate is pushed apart by the sliders causing the pulley faces to move towards each other. This pushes the belt outwards and makes the pulley larger.
Your initial acceleration is affected by how quickly the pulley can move the belt to the top of the ramp. Since the ramp is steeper on the Dr Pulley variator than on the stock variator, you reach the top of the ramp sooner, resulting in faster initial acceleration.
The ramps on the Dr Pulley variator are also longer than the stock variator. This means that the belt can be pushed farther up than on the stock belt, resulting in a higher "final gear ratio" than the stock variator can achieve. Because of this the variator can provide a slightly higher top speed than the stock variator.
This is one of the few modifications that will give you a boost in both initial acceleration as well as total top speed, making this upgrade a fantastic bang for your buck. It also is a very durable well built part, so you won't be replacing it later time to keep up with your mods.
Another bonus of this part is that the manufacturer coats the ramps in a friction reducing compound, so these variators are easiler on your sliders/rollers than a stock ramp resulting in longer lasting weights.
