A serious big-power turbo kit for the Raptor, built to chase power well beyond what a bolt-on Stage 1 or 2 kit can support.

why this one — FFP's own listing claims 700+ whp on E55+ fuel. A commonly cited "650 whp stock block" figure floating around forums is not a manufacturer number, so it's not treated as a real claim here. This is off-road/race use only, not street legal.

where the number comes from

FFP's own listing claims "700+ whp on E55+." A separate forum-circulated figure of "650 whp stock block" is a COMMUNITY ESTIMATE, not a manufacturer dyno claim. No independent dyno sheet found for either figure. Source: ffperformance.co/product/ffp-2017-2021-ford-f-150-raptor-trx-killer-turbo-kit/.

heads up

Manufacturer/retailer explicitly labels this off-road/race use only - not street/emissions legal. Custom tuning mandatory.
