1990's F1 Engine Torque graphs

All that has to do with the power train, gearbox, clutch, fuels and lubricants, etc. Generally the mechanical side of Formula One.

Hi All,
many thanks for all the precious informations.
I'm trying to remake all the power/torque curve of all F1 engine from 1992 to 2004, if someone have some data please let me know.
It would be mega to have torque and power delivery curve graphic.

Hit this link below to see a Honda dyno chart from the 1990s showing their G.P. bike power (~400hp/ltr).

The BSFC figures provide an additional view, at the time it was 32 litres?? with maybe 31 used

Comparing the power band widths of the four engines posted in this thread (very approximate.)

Method.
1. Establish the rpm range where power is greater than 90% of peak.
2. Express that range as a percentage of the upper rpm.

eg Honda RA122E (page 1) range is 12,200 - 15,000 rpm ie 2,800/15,000 = 18.7%
In practice this means a gearbox with 18.7% difference between ratios will allow the driver to stay within 90% of peak power.

RA122E - 18.7%
312B2 - 12.7%
MP4-4 - 19.2%
NSR500 - 13.6%
