I removed the needle on my speedo, and I need to know, what is the tach. at when your doing 70mph. I need a exact mark,dont guess.Thanks

 

wait...what?

 

You do realize every car will be slightly different due to different weights, incline/decline...?

 

there is a way to calibrate the speedo...look for it...

 

LOL at this thread....

well i know at 80 mph my tach is around 2,700-3,000 depending on inclines and exactly how much pedal i use... g/l man lol

 

at 70 mph i am just over the 2,500 mark, so 2,600

i know this because highways around here are 70 mph and I tend to watch my tach more then speedo at 80 i'm at 3,000

 

Thanks DaveVQ,What does the weight have to do with the speed of your car.As long as your in 4th gear its all the same. Yes all the cars are the same {all being 2k max with 4sd auto].The gear ratios are the same.Going down hill is another story,but i was not talking about that.

 

for the 4spd auto the exact number is more like this- 2500 rpm at 72 mph.
