⚡ At a Glance
- • Response Time: Rapid 0–full-scale needle travel in 333 milliseconds, accurate air-core electric movement
- • Best for: Performance drivers and track-day enthusiasts seeking precise shift timing
- • Not ideal for: Vehicles without compatible ignition pulse signals
Race-proven air-core electric movement gives fast, accurate RPM readings. A user-programmable shift light and incandescent front lighting aid visibility and shift timing.
Faster, more accurate shifts – thanks to air-core electric needle
Air-core electric tachometers use electromagnetic coils to drive the needle, producing very quick, low-inertia movement. The needle can travel from 0 to full scale in 333 milliseconds, delivering precise RPM readings.
Quicker, repeatable gear changes and better exploitation of the engine's power band, useful on track days and spirited road use.
Visible readings at night – with traditional incandescent dial lighting
Traditional incandescent lighting illuminates the front of the dial for warm, even illumination across the face. The black dial and silver bezel create high contrast for easier reading.
Clear RPM visibility during night running or low-light conditions, so shift points remain obvious when visibility is reduced.
Broad ignition compatibility – with 2–4 pulse signal support
Designed to accept 2–4 pulse ignition signals for 4–8 cylinder engines, compatible with points, electronic, and most 12V high-performance racing ignitions. Also compatible with both 12 and 16 volt electrical systems.
Fits a wide range of street cars and many race engine setups without requiring complex adaptors or additional modules.
