23mpg, 4.10s on the Highway NYC to NC....


just drove down to Wilmington, NC to see the family for Xmas. wooooweee its been a long year!! anyway just though I'd let the guys who are worried about screwing up their gas mileage with 4.10s know I got 23mpg on the highway driving around 75mph average....i took the same trip 2months ago with my car total stock with 3.27s and got 26....I got about a 500 rpm increase in 5th with 4.10s, but with the tune, and exhaust I got it compensates the rpm increase for damn good gas mileage I think....

also the passing power in 5th is awesome...

4.10s + N/A on the highway, and the street FTW if you ask me!!

yea, i was driving from wilmington to camp lejeune (an hour drive one way) and for a while i was gettin crappy gas mileage on stock gears, then i learned how to drive it and i found if i kept it under 2k rpm or at 1500 rpm kept my gas mileage good on my 00 gt. i had to let the mustang go, but when i get back, i'm getting another one and i gotta decide between 3.90's or 4.10's. either way, there both good gears, and by the way, i'll be getting an auto (don't joke on me too much k.lol.)

great to hear! though i am a v6 guy, i have 4.10s and have issues sometimes telling people that 4.10s or bust no matter what. hell, i even wrote an article about this topic with formulas and numbers to back it up, but some people are die hard 3.73 guys!

my problem with 4.10s was speeds aove 75, b/c 75 is exactly 3k rpms for me, and i redline at 6k. i am in my powerband at cruise and get less than what you get, but my city milage has greatly increased, and if i keep it under 70 on the highway (also reduces potential speeding fines) i have no problem getting 22+ mpg

I'm gettin a SC in 5 months....Im going to try it out with the 4.10s first since I already got them...but I might have to go to 3.73s....I know a few guys who perfer 4.10s with forced induction, but it seems like its just going to be too low for 1st gear.....still......Im going to give them a try for the hell of it...

Nice mileage for the thread starter. As for the auto I have one and could not have it any other way. The 10" converter from dirtydOg perfromance that will handle lock-up in 2nd gear at WOT and a 3800 rpm stall will make it pretty equal to a stick, maybe quicker-no shifts to miss! Though it's a bit off topic I apologize. I have 4.10's. mark

4.10s in an auto Mach 1 and just befor going to Bowling Green KY
from Indy I lost OD, made the trip anyway and cruising at 3500-4000
still managed 22 mpg. Granted you have to be real easy about how much and how quik you move the pedal to get that, but we did.
