Absolutely! But it's more of a fact...Torque Multiplication at the wheels. Your wheels are literally pushing with more torque, so you are climbing through the rpm's faster, lowering your 0-60 and reaching your top speed faster. If you have a manual transmission I would recommend to go with even smaller gears, like 3.91 or 4.11...If you went from 3.27 to 4.11 on a manual transmission your car would move as if it gained 70+ lbs of torque, even though it did not. This mod would require a computer flash to calibrate the speedometer.

Torq in Miramar is a sponser here on C5, ask for Eric.

Thats exactly the feel my a6 needs. Better low end acceleration and torque feel

Guess u recommend the 3.7 for the automatics? Upgrading to 3.7 requires a tune as well i assume?

Yohan honestly your FIRST mods should be to let the engine breathe: CAI and exhaust. These will only compliment any other future engine mods.

Yeah, I know that the a6 v8's have aggressive gearing and anything above 3.73 makes it difficult for them to keep traction, I assume the v6 gearing is similar. If I were you I would consult with Torq and see what they recommend...and yes you'll need the calibration tune Also, keep in mind that these mods/tunes can possibly interfere in future warranty claims...just an fyi

Found this regarding gear swaps on v6:

" As owners of the 5th generation Camaro continue their pursuit of more performance, many are swapping to a more aggressive set of rear end gears. While not an inexpensive modification, the bang for your buck with a rear end gear swap is hard to beat and the improvement in performance is dramatic. Making this sort of modification can be intimidating because many people don’t understand differentials and gearing. In this post I will try to provide some basic information to at least try and help get you pointed in the right direction.

How It Works

The rear differential is the device that transmits torque and rotation from the driveshaft to the rear axles which then drives the rear wheels. The rear end gears contain a ring and pinion gear that can be swapped to different ratios. The stock Camaro comes with either a 3.27 (all V6 models and the automatic SS) or a 3.45 (manual SS) rear end gear ratio. This means that for every 3.27 or 3.45 rotations of the drive shaft your rear wheels will turn once. A lower gear ratio means increased torque and increased acceleration without the engine having to create any additional power.

This all sounds great but the are some potential draw backs. A lower gear ratio means that your engine has to turn faster at cruising speeds which means fuel mileage can suffer. In the case of the 5th generation Camaro, the new six speed transmissions help mitigate the impact of this. Camaro owners that do a lot of highway miles have been reporting a loss of about 1-2 MPG, while those who drive mostly in town are reporting no change and even an increase in some cases due to the engine not having to work as hard to get up to speed.

The other potential draw back is that a lower gear ratio will shave away top end speed. This is not important to the average Joe since the Camaro is capable of speeds well beyond the speed limit right off the showroom floor, but for competitive drag racers it can be. It is possible that while the lower ratio will cause your car to accelerate faster it can also cause you to have to shift gears one more time before you cross the finish line, potentially sacrificing the gains made. Careful calculations should be made when selecting the correct ratio for these sorts of applications.

The Numbers

Camaro V6 Models Currently, there is only one gear ratios made specifically for the 5th generation V6 Camaro. For the V6 Camaros Richmond manufacturers a 3.55 gear ratio. With the stock 3.27s the automatic (A6) equipped V6 runs 1750 RPM at 70 MPH. Swapping to the 3.55s provides an equivalent torque gain of approximately 10% or 27.3 ld.-ft. of torque at the rear wheels and will raise 70 MPH cruising RPM to 1949.

The V6 Camaros equipped with the manual transmission (M6) come with 3.27s and run 2000 RPM at 70 MPH. Swapping to the 3.55s provides an equivalent torque gain of approximately 10% or 27.3 ld.-ft. of torque at the rear wheels and will raise 70 MPH cruising RPM to 2167.

The rear end in the M6 equipped V6 Camaro is similar enough to the SS that their gears will also work. Apex Motorsports recently had a customer install Richmond 3.73s in his car. The result was an equivalent torque gain of approximately 15% or 41.5 rear wheel lb.-ft. of torque at the rear wheels and will raise 70 MPH cruising RPM to 2277.

Make It Happen Hopefully, the information in this post has helped you better understand gear swaps. If you think a gear swap may be right for your project be sure to consult a professional during your decision making process."

@Henry---as far as exhaust, im looking for something that truly does improve performance. Sound is good, but improving overall exjaust performance would b great. Would like to do something more significant, like the Solo Mach X, which upgrades pipes as well, and might impact performance more. However, would like to see dyno numbers/graph to see if its worth it.

Mine will chirp third as well.

That's a nice feature of you m6 Camaros! Chirping on shifts Wonder if the A6 paddle shifting can also chirp?

Great info!

Hey bud, it seems to me like you are taking it easy. When I punch it my car shifts at around 7k rpms. If I paddle shift (which I don't mess with too much) I do it around 6500.

wow, thats how normally drive ur car out of ur driveway to work or to run some errands? If so, it must super fun, but what kind of mpg are u getting? If I got a truck or slow car slowing traffic down in front of me, yeah I get on gas, and rev it 6000rpm to blow by and move on, etc., but I dont drive it that hard for normal daily driving, especially city, since im also trying to get good mpg (23-25mpg avg hwy/city mix).

I've learned over las few days that indeed, these autobots like the revs, and as u and others pointed out, I was just.being too passive with it. Still learning its powerband, and happy to know it def can snap head back with a good push on throttle

[Prime]

Yeah, my response was after reading the first page. I read the rest after realizing it was 4 pages (doh) and see you were being a little more aggressive.

I don't always drive like that, but when I get on it, I punch it. I drive all city and punch it on average maybe 1 time to work, and 1 time on the way home where there are some good areas to open it up. I usually wait for about 10 minutes to let the engine warm up before I get too aggressive. If I am first in a stop light, I will usually let it go then too.

I am getting 16.4 MPG - all city with a lot of lights from home to work.
