FAQ
Will this support compound turbos and big injectors on an L5P?

Use the current two-filter strategy: XWS3002 with PF3001, or the extended-length XWS3002XL with PF3001XL.
What if my build is under 900 HP?
Consider the 220 GPH or 140 GPH systems for the same platform: TSC15250F220G or TSC15180F140G.
Noise level vs competitors?
