Sup folks? Just had a quick question. It's kind of an old topic that has been talked about before, but i can't seem to find that post so I'll just ask here.

Long story short; got a 5sfe celica that i need to readjust the speedo needle on. I tried setting it by RPM, as close to as i could remember, but whenever i blow by one of those police speedometer thingies on the side of the road, they clock me as being off by as much as 10mph. I suppose thats not a bad thing considering i have a lead foot anyway, and i know it will never be spot on, but what rpm are you guys running at at 65mph and so on? its a manual tranny. i noticed the discrepency after switching to ngk platinum plugs. currently it shows 3.5k at something like 80-85mph which i know is way off. only mod is short ram if that helps.

thanks.

No, it happened when you removed your needle when you installed your glow gauges like youre not supposed to do.

Generally speaking, in 3rd gear the rpm and speedo needles are identical. So cruise in 3rd and put the needle in the same spot as the rpm.

right on, this isn't on my celi. this is from a used cluster i got with no needles on it. i always knew it was off, just not by that much.

as far as I no dead on 4,000rpm is 110km (75ishmph)

I used this chart when i was learning to single clutch rev match.

i suggest you adjust your RPM/MPH using 5th gear, its easier to work with than decimals. i stopped calculating at 5k rpm cause the 5s isn't a high revving engine, so why bother... hope this helps.
