What to expect when you're expecting (gears)

Finally took a break from upgrading the Camaro and ordered 3.73's for the Mustang since the 2.73's are terrible. Floor the gas from a standstill and it feels slow, think our Mazda CX-5 accelerates to 4000 RPM's faster. I have an installer ready that will charge $180 for the install since I will have all the parts, he was highly recommended from other drag racers.

Now the questions, what kind of acceleration can I expect? I will be doing the break-in since I can do 4 cooldowns per day so how much time should I give my wife to get used to launching before we go yoto the track? How will the 235/50-R18 All-season tires hold up now? Before I had to do a brake stand to spin them.

Finally, why do Camaro V6 owners talk so much crap about Mustangs but won't race my wife's Mustang?

Husband = 2010 Camaro V6 Synergy Green Edition IPF Supercharger Best = 12.5 @ 111
Closest finish @ the line = Wife by 0.0028 seconds (4.79 inches)

the car will drive so much better you will wonder what in the world Ford was thinking with the stock setup...it takes 500 miles for break in, the tires will show no alter effects unless you do more burn outs, racing etc...
Chevy trash talk? Can you say "bail out", not to mention most hard core Chevy guys hate the Slowmaro..I will admit the new tail lights finally address one of the glaring styling issues of the car

I texted him to see if he doesn't mind me giving you his number. I am supplying the parts, so its $180 for labor. I know what you mean by the $500 for labor at other shops, made me tempted to do it myself.

Do I change the rear end gear oil at 500 miles? I will let my wife do that, I did that on my Camaro and that fluid stinks.

I like my Camaro for the color and style, good daily driver also. Upgrading it with a Vortech supercharger added quite a bit of fun. I probably pissed off a few of the Camaro owners though by saying if they wanted a good drag car, get a 5.0, lighter and faster than a SS. I also love the exhaust note on the 5.0, much better than the LS3.* Chevy needs to get the next generation Camaro weight down, then we will have a good pony car war. 3.7 is a good engine also, sounds good and has good torque. Just wish Vortech had a kit for it so I can use the same supercharger oil.

Excited about getting these gears in and I'm the one that has to race against them. Already have LCA's, still need to get a suspension package to get rid of the truck handling (my Camaro has upgraded suspension).

Ford was think about getting the most MPG as possible.

You may see a slight decrease in your gas mileage.

Thats what Fiestas are for.

I think of Mustang as their Hot Rod Model. Fettering a Stang with 2.73s seems a bit bi-polar to me.

And as one who changed up from 3.31s to 3.73s, there was a 1.5 MPG hit on the highway on the 4.6L.

I completely agree you. I'm not saying I agree with Ford's thinking. I'm just stating why they went with 2.73 gears.

Exactly how i felt after i bought my MT6 2.73. You have to wind the gears out to really see why you bought it. Anything below 4k rpms (like stated above) has little to no get up, after that it'll scream though. I do a mix of city/hwy, so my mpgs will go up with the 3.55s being installed at the end of this year, early next year. Plus my wife wants me to teach her how to drive it, i explained it would be much easier with steeper gears to learn how to drive.

You, or your wife, will love the change to 3.73s. Not sure how to quantify that "love" because there's no track here but believe me the gears with the tune made my wife's GTS a real fun car to drive! I'm not sure about the break in period. I read it all the time in the forum but the guy that put mine used to race Mustangs when a track existed here and said there was no break in period needed. He did recommend a fluid change at 500 miles which I did. My wife has the GTS suspension on the car with F1 supercars on the corners. I love driving her car hard into the on/off ramps here ... sorry that's all we have. I'm looking forward to leaving next year when she gets orders to go elsewhere .... I hope.

Got the gears today. The fire jacket is for my Camaro since you are required to have one if you have an aftermarket power adder. Gear install is scheduled for Monday, can't wait to see how the car feels after this. Will probably have to get gears for the Camaro after this, but it will cost me near $3000 since I have to buy a brand new differential, driveshaft, axle, and hubs.

There's no way a CX-5 will beat even a V6 Mustang. Second, you'll love the gears. I was quoted around $300 for install if I ever wanted to do it. My 3.31s do just great though.

I know a CX-5 won't beat a V6 Mustang, after 1st gear it has no power. From a standstill it just feels faster till the Mustang hits 3500 RPM's due to the 2.73's. Thankfully that will be fixed Monday, should have done more rresearch and gotten the performance package, but my wife fell in love with the grabber blue and matte black stripe.

Going to be an interesting drag race now, the Mustang will have the torque advantage over my Camaro, but once the Vortech spools up can the Camaro catch the Mustang? Going to be some awesome GoPro vids.

Its not, I haven't updated my signature with the new times because I still haven't gotten a full run in with my new setup.

2010 Camaro V6 Supercharger First Runs - YouTube

That was the day I had installed the tune on the car and drove it for the first time. I wasn't planning on racing so I had my subwoofer kit and a bunch of junk in the trunk. I got peer-pressured into racing, our friend (the first V8 I race in the vid) wanted to see what the car could do.

Didn't have a wideband gauge installed, a month later when I did install it my car was running a 10:1 AFR, popping like crazy from running too rich. My Intake Manifold has come apart twice from the extreme heat and pressure, my catalytic converters had started to melt so they are now gutted.

I'm ready to go back to the track to see what the 3.73's do to the Mustang and to see what all the tuning and fixing has done to the Camaro.
