i dont know how fast my ranger really goes...the govner kicks in a 90 mph

 

Maybe not your truck, but mine sure is!

 

Maybe

 

what vid? i cant seem to find it?

 

That might work ok with a manual tranny and a clutch that has no slippage what so ever, but I highly doubt it will work with a 5 speed auto with a stall converter and lockup. I might be wrong, but there are too many other factors for that to be accurate.

 

The one you loaded for my site's front page

 

Doesn't lockup mean "locked up" no-slipping? If so than that is the same as a clutch, you just need your final gear ratio. But in a stock automatic yes that forumla is not accurate, there is some losses due to slip but should be with in 5-10% error?

 

about 88 is all my truck has.....with the 4.56's......i can get going faster down hill, but not much more on straight flat land....

 

Well you are prolly right 5-10%, but at wide open throttle, the tranny comes out of lock up. So im really not sure if anything is accurate except a radar or gps...

 

I dunno how fast it will go but I made sure the speed limiter was gone after I put in the program from my Bama Tuner and it was...lol! I guess I got it up to 105 for a really short period of time and that was way faster than I felt comfortable while driving it. I hit a max of maybe 75-80 on the interstate now and no faster. I remember when I was in high school (early/mid 90's) back in my dumber days most cars only had 85mph speedometers and we would see who could wrap them around the farthest...lol! The '87 Escort GT I had at the time would bounce the needle off of the trip odometer reset button sleeve if I got a good run going down hill! Man that poor car saw some hell but it never broke on me.

 

I want to know why car manufacturers make their cars to go 90-110 mph when you can only legally go 55mph in most places, and about 75mph max on interstate.

 

ive done somewhere around 90, my '88 would only do 75 though.

 

I put a lot of highway miles on my 02 FX4, And 92 MPH is the top end even after the new 32x11.5 T/A's were added.

 

She has almost 164,000 miles and runes like new, Except for the Torsen carrier is now busted apart.

 

I hit 5200 at 115mph, got it on video..

Rocky

 

i havent been over 80 in mine. i just dont wanna push it that hard since it is my daily driver

 

had the speedo in mine say 90 with the 38 and the 5.13's.

 

130+ mph here. Heh. Got to love a truck with no governor.
