Rpms and tach????

Just installed a tach in my 91 HB and hooked the green wire to the blue behind the cluster. Just want to make sure im getting the right rpm readings. So my question is during normal driving approx whats the max rpms everyone is turning on average???


thanks

Well what do you mean by max rpm's. If you're trying to figure out if your rpms are right...run your car at a certain speed in a certain gear and come on here and see if that is the same with other people with the same engine/tranny as you. For instance, with my car 80mph in 5th gear (Si Tranny) my rpm's are at like 4,000.

ok its a DX and in 5th @ 80 mph its 2k RPMS

thats sounds really low
i dunno though

thats what i thought but at idle and lower speeds it is on the money. Car idles at about 500rpm.

ok its a DX and in 5th @ 80 mph its 2k RPMS
does it ever go past that area even at the top of the gear eg 30 in first?
try it out it could be wired still for a 8.

Yeah I know the Si and dx have different gears but I don't think you're running at 2,000 rpms @ 80mph when I'm running 4,000 rpms @ 80mph. That is too much of a difference, in my opinion.

your tach is messed up or its not calibrated right my dx 4th gear all it has and 80 is almost 4k

i agree with him above

ok thanks everyone!! been away for a few days the tach is set up for a four but it may be messed up thanks again
