  2. Chrysler RFE transmission - Wikipedia

    en.wikipedia.org/wiki/Chrysler_RFE_transmission

    In the 45RFE applications four gears are utilized. In the 545RFE four gears are used on the upshift and a new "gear", 2nd Prime, was used with a different (1.50:1 rather than 1.67:1) ratio to increase versatility when downshifting. Although, with some tuning, you can get the 545RFE to upshift into 2nd Prime. [2]

  3. GM 4L80-E transmission - Wikipedia

    en.wikipedia.org/wiki/GM_4L80-E_transmission

    The 4L80-E uses two shift solenoids, initially called Shift Solenoid A and Shift Solenoid B; they were later changed to comply with OBD-II regulations to 1-2 shift solenoid and 2-3 shift solenoid. By activating and deactivating the solenoids in a predetermined pattern by the PCM, four distinct gear ratios can be achieved.

    If 25%–50% of the scheduled race distance is completed, points will be awarded on a 13–10–8–6–5–4–3–2–1 basis to the top 9. If 50%–75% of the scheduled race distance is completed, points will be awarded on a 19–14–12–9–8–6–5–3–2–1 to the top 10.

  6. Ford MT75 transmission - Wikipedia

    en.wikipedia.org/wiki/Ford_MT75_transmission

    In 4x4 versions, the planetary gear center differential with viscous-type limited slip is integrated in to the rear half of the gearbox. The 4x4 system is of full-time type with a static torque split of 34% front, 66% rear (similarly to Type 9 4x4 models). The MT75 has five speeds and reverse.

  7. Power-to-weight ratio - Wikipedia

    en.wikipedia.org/wiki/Power-to-weight_ratio

    A typical turbocharged V8 diesel engine might have an engine power of 250 kW (340 hp) and a mass of 380 kg (840 lb), [1] giving it a power-to-weight ratio of 0.65 kW/kg (0.40 hp/lb). Examples of high power-to-weight ratios can often be found in turbines. This is because of their ability to operate at very high speeds.

  8. Hazard ratio - Wikipedia

    en.wikipedia.org/wiki/Hazard_ratio

    The curve represents the odds of an endpoint having occurred at each point in time (the hazard). The hazard ratio is simply the relationship between the instantaneous hazards in the two groups and represents, in a single number, the magnitude of distance between the Kaplan–Meier plots. [7] Hazard ratios do not reflect a time unit of the study.

  9. Data compression ratio - Wikipedia

    en.wikipedia.org/wiki/Data_compression_ratio

    For example, uncompressed songs in CD format have a data rate of 16 bits/channel x 2 channels x 44.1 kHz ≅ 1.4 Mbit/s, whereas AAC files on an iPod are typically compressed to 128 kbit/s, yielding a compression ratio of 10.9, for a data-rate saving of 0.91, or 91%.
