i know im no genius and i never claimed to be a math guru...but im pretty sure that 39 divided by 10 is 3.9

maybe im wrong, maybe im not doing something right.

3.55 39 tooth ring 11 tooth pinion 39/11 = 3.5454545454545 or 3.55

3.92 43 tooth ring 11 tooth pinion 43/11 = 3.9090909090909 or 3.91

3.90 39 tooth ring 10 tooth pinion 39/10 = 3.9000000000000 or 3.90

4.10 41 tooth ring 10 tooth pinion 41/10 = 4.1000000000000 or 4.10

4.56 41 tooth ring 9 tooth pinion 41/9 = 4.55555555555556 or 4.56

...but maybe im wrong.

 

honestly...not trying to be a smart @$$...lol.

someone please tell me if im doing that wrong. it made sense to me so i ran with it.

wheres the rearend specialists??? lol

thanks

 

Yes, 39/10 on ring & pinion will give you 3.90 final

15.8 with the bolt ons you have is ok for a 5.2
Guy I know from few years back on another site ran 15.35 with bolt ons & a 5.2.

FYI, takes about 500hp (390rwhp) to run a 12second pass with a Dodge Ram r/c s/b.
To run a 12 second et with only $2k budget I guess you will be stealing at least 3/4 of the parts needed lol

 

Yea I'm inpressed! Sorry but it was just hard to belive that you where getting that low.

 

luckily all of my machine work is free! my neighbor is a 20yr+ machinist and he does all kind of cool stuff for me in return for free satellite.

the labor will also be free not counting the time spent to do it.

as far as parts go... i have a few customers in the hot rod business and im hoping to get better deals thru them.

the problem is "what do i do?"

that 12.91 is impressive!

 

i guess getting rid of the new mudders might help

 

I'll take them!

 

hmmm... i dont know if the 5.0 here would appreciate me driving around on just steel wheels

 

Well thats there problem. lol. I'm in the market for new tires.

 

how much do you want to spend
