question for 140 speedo guys

What does 3500-4000 rpm in 5th gear correspond to in MPH? 88 TC 3.55 gear. My stock speedo was bottomed out :/

no i wasnt racing, i was crapping my pants. young, dumb, and full of rum. okay, no rum. Just me and an open backroad.

according to this you were doing about 110 with a .8 5th gear and 26 inch tire.

thanks

lil too fast for the conditions, wet road, fair tires, night, yeah.


i think im going to find a spare stock speedo and try to convert it.

I put my first Turbo Coupe in a ditch speeding in the rain. Luckily the only thing that was harmed was my pride. Be careful!

strange, according to that calculator i should be doing 56 mph in 5th at 2000 rpm, but according to my speedometer i actually do about 50. I wonder if the speedo could be that inaccurate, or maybe something better... like... ~3.90 gear?

i think most of the speedos from our cars, and any early ford are kinda sketchy. always seems im doing 5mph slower than my friends when they are doing the speed limit. and that speedo mod is easy, hardest part it makeing a background for it. i was thinking of making a bunch of them and selling em as mod speedo's NOT fms ones, dont want to get fined lol.
