V300SD data recorder is the most common recorder for Pro Stock, Pro Modified and many other Sportsman classes. In its base configuration, the V300 monitors six parameters (engine RPM, driveshaft RPM, accel G, lateral G, battery volts), but it can be expanded to monitor up to 67 channels of data to meet the needs of most users. Any monitored function can also be displayed in real time on Racepak’s IQ3 or UDX dashes. Datalink Lite software is pre-installed, giving the user the ability to record, download and perform telemetry (real-time) sessions, as well as add or remove new sensors and modules.

The Holley EFI Interface Module streams data from your Holley Dominator ECU systems to any Racepak data logger or dash display.

Racepak A/F sensors are compatible with either gasoline or methanol fueled engines. Each of these 2 and 4 channel controllers are designed to be connected to the V-Net cable of Racepak V-series recorders. All sensors have a 13” pigtail cable, and the controller has a 37” cable for attachment to the sensor. These lengths cannot be altered. Controllers are ordered by cylinder bank layout.

Racepak’s 8-magnet collars are perfect for automatic-equipped vehicles. These collars assist in picking up driveshaft RPM sooner than a conventional 2-magnet collar. Available in four popular sizes: 1.812″, 1.875″, 2.125″ and 2.187″.
