Professional-Grade Fuel Injection Wiring Solutions for Sportsman Racers

Speartech Fuel Injection Systems has partnered with Modern Racing to deliver high-performance electrical wiring for sportsman racers, targeting pro-level reliability and accessibility across grassroots drag racing and related disciplines.

The collaboration blends Speartech’s manufacturing depth with Modern Racing’s track-side engineering, aiming to close the gap between elite teams and independent builders through standardized, durable, and serviceable solutions.

Speartech builds LS and LT retrofit solutions, including EFI conversion kits, standalone harnesses, and swap electronics, backed by longstanding customer support for installers and racers.

Founder John Spears brings 23 years at General Motors in electrical systems and engine control development, underpinning Speartech’s early leadership in GM LS and LT standalone harnesses.

Modern Racing, founded in 2016 in Mooresville, North Carolina, supports NHRA, NASCAR, and OEM programs with custom wiring, electronics integration, chassis solutions, and trackside service.

Cost and complexity have historically gated professional wiring, concentrating capability with top outfits. The partners target simpler architectures and clear documentation without compromising performance.

Packages are intended to emphasize reliability, ease of installation, and serviceability, suiting sportsman classes and high-end street-and-strip builds that demand repeatable performance.

Modern Racing owner Justin Elkes frames the tie-up as merging production scale with hands-on development, yielding harnesses that reflect elite standards yet remain attainable for enthusiasts and builders.

Joint product development and validation are central. Testing protocols will mirror competition stresses, while technical support aims to shorten troubleshooting cycles at the shop and the track.

In parallel, Speartech continues advancing EFI and wiring technologies familiar to its customer base, extending compatibility and refining calibration support.

The initiative broadens access to robust electrical systems, positioning sportsman racers to chase professional-level durability and data integrity without the traditional resource barrier.
