Turbocharger Specifications
Charles Brooks
Introduction
This is an updated turbocharger comparison including some of the more recent entries in the TR world. Information was gathered from the respective manufacturers and verified via phone conversations. The information includes the manufactures recommended minimum stall speed, minimum fuel injector size, and estimate of maximum horsepower.

Each manufacturer pointed out that HP estimates are difficult given the numerous configurations or ""combo's"" found in the TR/GN world and there is some margin of error in the numbers which is unavoidable. Horsepower estimates are exactly that, ESTIMATES. They are not performance guarantees for any particular vehicle or application. HP estimates are given here as another data point to be used in comparing the growing number of turbochargers on the market today.
