GYT-R Velocity Stack Kit
|
For closed-course competition only. This kit has velocity stacks that can be installed two ways to tune for different power gains. For improved power across the power band ( ideal for road racing). Move the two stock outside stacks to the inside (cylinders 2 and 3) and then use two stacks from the kit on the outside (cylinders 1 and 4). For maximum horsepower on top (ideal for drag racing), use all four stacks from the kit. Gains of 5 hp on top can be achieved with proper tuning- no remapping is required.
