That car is not N/A so we're not talking apples to apples now are we?

Read your quote."I haven't seen any good times with 4.10's. Show me. Otherwise this statement is false."

I showed you.

Also, even WBT is counseling people to"maybe" try a 4.30 gear. Wow!

Read the comments.

car is a 2012 GT Auto, longtubes, off road h, full magnaflow comp system, JLT cai, circle D 3600, 3.73's & a lund/evolution 93 race tune, poly mounts, upper/lower control arms, but i have been using 26" slicks..weighs 3570-3600 lbs as raced (without me in it) my car shifts at around 7500 rpms, but have never trapped higher than 118mph, even after 20+ passes. I am going to get the aluminum driveshaft next month. Should I step up to 4.10 or down to 3.31 and use a 28" tire, or add boss manifold now

I would move to a Boss intake, 28" drag radial, and the gear depends on what you want to do. 4.30 is great if you can get the car to hook. 3.31 will be more consistent hooking but not as fun on the street. You will have to decide on that.
You could also do with a little higher stall converter. 5C is what I am using and works great for a N/A setup. If you plan to go FI/nitrous you may want to stick with the 3C you have now.

Bottom line OP. Try what gear you want. Have a blast.

This thread was about N/A autos. Shoot you should be the poster child for 4.10's in an auto fail. You couldn't get out of the 13's.

I love the fact that it is just a a milli second for you to stick your foot in your mouth again.
Last run was 12.55 @ 111

What was yours Scot? Just another arm chair drag racer. Show your stuff .
All you do is **** on people and claim you know some thing about what you are talking about. You talk the the talk , but no walk. Show us !!

To OP.
Get 4,10 or 3.73. You will not be disappointed. You MIGHT get a good time with lower gears. But you will have a load of fun with with the gears. Take it from some one who has had 3.15 and 4.10. Big smile on your face.

Casper GT who posts on a couple forums runs 4.10's in his GT and runs 11.71 @ 119.
Not to say he could not get this with a lower gear.

Actually my last outing just before my track closed this year I ran a 11.91 on tune, tire, and exhaust. With 3.15's. I just don't go around everywhere like you thumping my chest. So please don't pretend you know me. Enough here. Put whatever gears in that floats your boat. I could care less.

3.73's will feel much snappier than 3.15's and your GT/CS will feel much lighter and quicker. They may not make your car any quicker at the dragstrip (although I believe they will), but if you're more interested in how they feel, then you're gonna love the 3.73's.

Same logic applies to axleback mufflers. They don't make our cars any faster, but they sure satisfy our ears.

Same logic also applies to aftermarket air intakes (aka CAI's). They don't make our cars any faster (unless you also buy a tune to go with it, but then most of the power gain is really from the tune anyway). However, these aftermarket air intakes are great eye candy when you pop open the hood.

So, there are some very popular mods that we all tend to do to our Mustangs that don't really make our cars much - if any - faster, but they satisfy our senses none-the-less, and that is plenty enough reason to add them to our cars!

Was going to link Casper's times and several others in the mid-11s that have done minimal modding and gone to 4.10s. Other than a converter or major modding to the engine internals, gears and tunes are your best bang for the buck.

Grabber, there have been decent times for all varieties of gears, but the bell curve seems to be centered around 3.55 for all N/A cars in general. However, that's N/A but not necessarily stock longblock and internals, and many are getting great times with those gears because their power is much greater than a "normal" minor modded N/A motor (just like FI guys go for 3.55s over 4.10s, they don't want to blow the wheels off with too much gear and power). To help get out of the hole with a 400-500whp N/A car lower gears like 4.10s multiply the torque to gain mechanical advantage; with a 500+whp car (modded N/A, FI, nitrous, etc) it's likely that you make enough torque down low that you don't need gearing out of the hole (or could even spin badly) and instead gear for better mid and top end of the track to utilize the power band fully/shift one less time/finish near redline, etc.

So, for the previous comment that my statement was false, I disagree...you can always find a setup that works better than others for just about every car, but in general on a slightly modded N/A car a lower gear (like 3.73, 4.10, 4.30) will help in general to get out of the hole and increase acceleration. On more modded N/As or power added motors like FI or nitrous a higher or midrange gear (like 3.31 or 3.55) can be a better setup for the power being put to the ground. It's the general consensus around the Mustang communities that 3.55 is producing the best times for N/A* cars (asterick meaning N/A in general terms, not just a CAI, axleback, etc and it includes forged internals and non-stock blocks) but excluding more modded cars 4.10 is the go-to gear for the fastest times. Clear as mud???


OP, if you're staying fairly light on the mods (CAI, axlebacks, tunes, maybe smaller nitrous shots) go with 4.10s and I think you'll be happy. If you think you're going with a blower, turbo, or a big nitrous shot (200+) in the near future you probably should stick with 3.55, 3.73 or even 3.31 - I personally would go 3.55 in this instance as it seems to work the best for FI guys.
