Tonight around 12:30 I went onto the freeway just to blow some steam and I gunned my car and noticed that it redlines around 113mph. There was a slight breeze, temp was around 74 and I drive an auto. Anyone know why I can't make it to the 127? Just curious. No mods to my car. And I was going on a slight downgrade section of the freeway. Before you flame me, there was close to no traffic on the road.

 

no clue..my automatic does a 127 all day long no prob..were you in third gear maybe?

 

Third gear doing 113mph? The guy said he drives an auto.

 

im an auto, i got to 118 before i ran out of room

 

I leave speed for my motorcycle....

 

Its possible. Did you turn overdrive off? That'll force your car to stay in 3rd, even during full-out acceleration runs. Otherwise, it should shift to 4th.


Technically, the much-shorter gearing on the 5spd will max out around 135-140 (this can be mathematically determined, but i'm not caring enough to do so.) Obviously, the limiter prevents this.

The auto has taller gearing, therefore, should have a higher top speed. The "tallness" also results in a very signifigant difference in acceleration, in addition to the increase of friction losses through the drivetrain.

 

yeah, you must be moving the "shifter" into the "3" spot instead of the "D" spot. my auto will do 127-130 depending on the grade of the road...

 

127 and then my tC gets choked...

 

I get it now, manauls are quicker...
in a drag race, would there be a significant difference? manual vs auto?

 

Uh yea... 5spd win by about 4-5 cars

 

There is a third gear in auto dumbnut... 3-D DUHHHHHH

 

128-129 rev limited via flat elevation....
5speed

 

nope it was in D.
