At 1:1 in third gear that is so, but in OD it is 371 RPM. Use this link when you want to tinker with gear, tire or tranny's to find the outcome. They have them in RPM and MPH based calc's.

Hope this helps

Ps. Hankfan,
I hate to say it but.........I told you so!

 

I think the 4.10 gear is an excellent idea. I would expect your et will drop a couple of tenths in the quarter.

 

HI!... Well I drive in 3RD gear 95% of the time. I only use overdrive when on the highway.

 

4.10s are sweet. So good in fact, That I put a set in my wifes crown Vic!



WOT

 

1BADTK- Yeah I have to say you were right. The Gen 2's should have came with 4.10's from the factory!

owheelies- Yeah it's just a touch over a 300rpm increase in OD. I wouldn't even be able to notice the 300rpm increase at cruizing speed if my exhaust didn't get so much louder. To be honest I don't even notice the 4.10's while just cruizing around but at WOT or from a dead stop there is no doubt your running 4.10's. It almost feels like your running the juice full time!!!

 

HANKFAN
Everytime i read your post i cant wait to get mine in. Im saving from now for them i cant wait.

 

Oh yea i race with the 28" tall hoosier slicks to. So what do you think i will be going through the traps at. I know it should help my et's drop. Best was 12.85 that was with bumper on to weighing 4800 and 3.55's. So i think with the less weight in the back and 4.10's with 28" tall hoosier slicks will help me drop them. The 3'55's are killing me at top end . What do you guys think?

 

top end with the 3.55's suck 4.10's are next for sure!!!!

 

Thats what im talking about. I get killed at top end with my 3.55's. The 4.10's are my next mod. Time to break the piggy bank open again HEHE

 

I am running 26-11.5-16 et streets with the 3.55's. i just bought 4.10's dose anybody think i will be running out of gear w/ the 26 inch tall et streets and the 4.10's. so far my best et is 12.9@104. dose anyone think i would go slower w/ the 26's and the 4.10's

 

those gears i don't think will net a couple tenths,

to give an idea, i have the 3.73 gears, and was running a 28" tall slick on a 15" wheel

i switched to a 26" et drag which effectively gave more gear and i expected better et's, and i noticed no gain,

if he hooks up, he may see .1, you gotta remember, these trucks make torque down low, so the truck pulls good at low rpms,

 

1BADTK told me that he gained 2 tenths in the 1/8 and 3 tenths in the 1/4 from switiching from 3.55's to 4.10's while running
28" Hooiser's.

 

Thats what im talking about. When i ran my best of 12.85 that was with stock 3.55's, on just warm weather side of chip, on pump gas, and weighing in at 4800 lbs. Now bumper is gone and thats about 80 lbs there. That combined with the 4.10's when i get them hoping to see nice improvement on my et .
