Q About Gears.

I have 4:10 in my 5.0 stick. I am taking it out and putting 3:55 in it. It's too tall for the city for sure. I mean i beat everything light to light. but on freeway it's not very ideal. Putting the same 4:10 in my 4.6 auto. Makes more sense. I am still trying to figure out how to race both my cars at the same time....

BUT if you are racing your car at the track all the time...then go for 4:10 with slicks and skinnies. it's fun

But would 4.10 in a aode affect mpg and the rpm at 75mph?

Click to expand...

my gas mileage hasnt changed THAT much... but enough to be somewhat noticable... not too bad tho...

i absolutely love my 410s on the stock motor/aode... gives me a nice little head jerk, but i think once i complete my HCI swap in a few weeks, ill be seeing some noticable "in seat" reactions

will a custom tune be necessary with gear swap?

no sir

here's a little info to chew on:
Aode Ratios: 2.40 1.47 1.00 .67 N/A
TKO600 Ratios: 2.87 1.89 1.28 1.00 0.64
(^i have both of these)
and the stock T5 3.35 1.99 1.33 1.00 0.68

assuming a 26.04 in tire - 255/50/16 MT ET Street (774.89 revs per mile)

All measured in OD of the trans.

I have a 95 cobra with an e303 and 4.10s and exhaust and tune. I got 21mpg it was pretty much back roads about 70mph drive. About 240 miles per tank i believe.
