How HorsepowerFactory Reviews Products

Tarquin Osei, Founder & Lead Editor
This page explains how HorsepowerFactory turns platform-specific research and real-world owner data into buying guides you can actually trust.

What this site does

HorsepowerFactory is an editorial operation built on 28 years of reading dyno sheets, comparing part catalogs, and listening to what actually works on forums and independent logs. I’ve been the guy staring at a catalog trying to guess which parts match my goals, and this site exists to short-circuit that guesswork. We aggregate owner-reported results, factory specs, and tuner feedback to produce honest, platform-specific guides — from a first intake to a full turbo build.

How we evaluate

  • Owner-reported dyno pulls and track times across multiple forums
  • Part compatibility and fitment notes from verified install threads
  • Long-term reliability reports and known failure patterns
  • Price-to-performance math across budget, mid-range, and race tiers
