clutch slip do to high hp with sunburst fix with jbeam?

i looked it up couldnt find much but this link on reddit ( https://wiki.beamng.com/FrictionClutch.html ) this seems to be what im looking for but i dont know how to put in the line into the jbeam file for it to read it it seems pretty simple i just dont know what im doing wrong maybe im trying to add it in the wrong place anything would help its something along the lines of maxclutchtemp then the temp number and brackets or something else i added the jbeam file i believe it goes in so you dont gotta dig for it
