1900 at 65mph and still getting really good 23-25mpg with the 4.10s

 

god i'd love to get gas mileage like that, but then at the same time i love not having to worry about missing a gear in a race.

 

get outta here with ur missin gear **** pny lol jk man. So the lt1 wont pull as good of gas mileage as the ls1 guys huh??? that sucks but hey 23-25 with a v8 sports car is damn good in my book thanks for the info guys. Six speed and 410's in a moser 12 bolt comin soon hopefully.

 

I would say just a few MPG most.
When I did the 3.73s I could barely tell the diff. over 3.42s, yes it was alittle more snappy but not what i wanted and I was never satisfied. I know better this time around.
A4 is a diffrent story 4.10s will suck gas pretty good.

 

so if i did the 4.10s and got a eaton posi under my truck, waht would u say i could run?

 

i went from 2.73 to 4.10 in a A4 with mods in sig, other then it using a little more gas with the ss4000 i love them, breaks the tires loose at 40mph using 275 street tires

 

low 13s or so on sticky tires. How much does it weigh?

 

im thinking about going with 4.10's in my bolt on only car with a SS3600

 

the last time i went on a long trip i managed to pull off 29.5 mpg(432miles traveled to 1 tank) with the 3.42 gear. since that time i added Lt's,true duals,cai,tune,plugs,wires,4.10s so i would guess using 6th gear more often i most likely lost 1.5mpg WELL WORTH THE SACRIFICE!!!!
i love video w/audio get to hear THEM DUALS from the outside

 

around 3000 lbs....give or take a few lbs for my wieght n that stuff.

 

yeah..... low 13s high 12s

 

damn i like the sound of that,

 

i am for sure low 13s will happen even at the altitude i am at. i did notice my car was running good but something just did not feel right found this today


fortunately i have 16 left overs well 15 now!

my buddy had a 94 z28 coupe,m6.mods were:
stock unopened Lt1 78k
Jet Hot Lts
3" Y-pipe cut-out
k&n cai,small pooper scooper underneath
52mm tb
added a vented opti and dowel pin
new timing chain
autozone clutch (LOL lifetime warranty)
madtuner cheap tune(100.00)
3.73s
nitto DRs 245/50/16
ripper shifter
ran 13.3s 1.9 60' NA and 11.3 on a 150 shot,got greedy and put 175 pills in there(against my advise!) stock fuel pump Motor went

 

elite what is the DA there. I lived in phoenix for four years and it was like 125 degrees and i forget the altitude i know it aint low i wanna say 2000 - 3000 feet. Now i am in florida tons of humidity but gainesville raceway is like sea level.

 

How are 4.10's when it comes to normal, every day driving, and how much does a new rear end cost?

 

To be honest,my silver car is my every day driver. The 4.10s make the car way more efficient,when you leave from a stop light the car is gone compared to the 3.42s.......I run on c6 285/35/19s and of course they tame the gear down a bit. My next track visit will be on stock size 245/50/16 DRs.
Generally you will spend 180.00 on the gear and 200.00-300.00 for the instal,so when you begin to look at the dollar to performance aspect it is the same as adding Longtubes and Y-pipe. you will not regret this mod!!!!

 

how do i find out what the DA is i never checked that

 

I lost almost nothing by going to 4.10s w/ my m6 and I don't drive her easy.

look up a DA calculator...usually altitute, dew point, barometric pressure, and temp are taken into effect. Your gonna have to find a weather site that will give you that info

 

From everything Ive heard 4.10s make for a better DD. over the 3.42s. Clutch chatter is almost eliminated also.

 

100% correct
when i leave a stoplight the car actually lunges foward now. it's almost like re-learning how to take off normal again.....
