Wow! Those almost exactly match my 2009 Mustang GT's figures. I think
I'm a little higher on the HP & Torque, due to a CAI in addtion to the
muffler replacement. Not too shabby in either case ...

"Actually you have a LOT more TQ! That the important piece a lot of
the Chevy fanboys forget! Too many people go "WOW! 300 HP!! I can
beat a Mustang GT!!" I simply laugh at them! I know BETTER! The V6
Camaro only has 273 ft/lbs vs the GT which is more like 320 ft/lbs!!
Also my Camaro is a BOAT! She weighs in at 3800 pounds!

"So yeah, everyone want to compare this V6 to V8s.... I think that's
silly! Compare it to other V6s! The specs are pretty interesting
too... like 11.3:1 compression ratio on 87 octane! LOL!

"But you are right... it's not to shabby! I am really enjoying the
car! Lots of trips to the drag strip and even a day on the road
course! It's a very fun car! And most importantly i'm not
delusional over just how good it can perform! LOL!"

Well, that's what they are for!

I think all the modern "pony" cars are more like "dray horses"; give us a 10% or 12% cut in all dimensions and we'll be back within the original concept.

I gave my convertible a pretty good workout last Friday night at the QualComm Stadium RaceLegal drags. It's not a good track, only eighth-mile, but it's nearby and near sea level, so I think you can draw some legitimate conclusions from the data:

Car is a 2008 GT/CS automatic convertible, 2,100 miles on the clock. "Bullitt" FRPP CAI, GTA mufflers. About five gallons less gasoline in the tank, second day. First week was all top-down runs; after probably sixty passes with the top down in this and the previous V6 convertible, they finally said I needed the top up or a full-face helmet (boggle). Same everything else, as near as I could tell.

With the Torque and Race tunes, the car chirps the tires on the 1-2 shift; gear changes are dramatically quicker, on the order of one-fourth the elapsed time between one gear and the next; shifts are much sharper, by which I mean to say quicker in time and with no perceptible "taper" to ease from one to the next. Gear changes with wide-open throttle are at 6,000 RPM, close as I can tell. In the Torque Tune, the exhaust note is "punchier" than stock, to my ear; "taut", "tight" also come to mind. I don't know how to measure that. I haven't driven the other tunes on the street, so I can't report their sound differences, if any. It takes a much lighter touch on the pedal to increase acceleration; neck-snap latency is reduced. In "D" the transmission stays in lower gears to higher RPM on light throttle. I could be in 4th overdrive by 25 MPH on stock tune: it won't come out of third until more than 35 MPH.

I think I have eliminated all the transcribing errors. Perfect Reaction Time is 0.500. I converted red-light R/Ts to positive difference to make it easier to get them into the spread***. I believe the left lane is slightly faster than the right. I tried to use the same technique for each launch: just enough "burnout" to dry the water off the tires; brake-hold at 1,500 RPM; slap the throttle when the second light goes off; let the wheels do what they will; accelerate well past the finish (I like braking, too)(amazing to me how many opponents quit while they are behind, and how many sandbaggers are there looking for a cheap trophy). I actually had the impression my best run was that good; otherwise, only a very general "better" or "not so good", not always correct.

I must find a quarter-mile track near here; I think the clsest one is a hundred miles away, and I'll bet the on-track traffic won't allow anything like the number of trials I can get at Qualcomm.

Cheers!
