Late model muscle car's

[Jeff Lee]

OK, I'm finally getting out of the stone age. I drove a 2008 Mustang GT/CS with an auto trans last week. All stock except Roush air intake. It had 3.55 rear. I couldn't believe how fast it was and was most impressed with the way the 5-speed auto trans performed. I mean, it didn't even slow down 5 RPM when it shifted from 1st to 2nd, it just kept accelerating. The last Mustang I drove was 3-4 years ago and it was a '98 (?) 4v Cobra. It was a lot of fun and would rev real high but had no bottom end. This 300 HP 3V '08 would probably blow it away. I have my eye on getting a 2010 Shelby if my new business works out. 540 HP w/ a 6-speed in a Shelby for $46K seems like a bargain to me. Thanks Evan.

Went to the track last night for the first time in over a year and drove a friends '06 Mustang GT with 3.55's and a 5-speed manual. It has a chip, intake and cat-back. It also has hard, worn out standard issue tires that need replacing. Obviously it took some finesse to launch it. I went 14.38 @ 101 MPH (it was 111 degrees out earlier in the day). Previously the owner has seen 104 and some change in cooler weather. He's got a total of $8500 in the car as it was an impounded vehicle. That's a mid-low 13 second street car with a/c with some ET drag slicks. Those MPH he runs are as good or better than my last "hot" street car, a '72 'Cuda with a pretty decent 340 and it sure wasn't as nice of a driver as this Mustang.

And the big disappointment was our friends '09 Challenger SRT8 with a 6-speed (all stock) and 3.08's in the rear. It was the first time down the track. Traction was an issue but even so, the MPH was only 98. That's only showing around 300 HP at the flywheel instead of 425 HP. I suggested he take it to the dealer because somethings not right. Anybody see any SRT8 Challengers on the track yet (stock)? A friend of mine in California has a SRT8 300 and can run 13-teens almost anytime. I'm not sure of his MPH.

I was at at test & tune Friday with my friends Super Gas car. On a whim I decided to make a pass in my new Challenger. 5.7 motor, 3.06 rear and auto. Left spare tire in and 3/4 tank of gas. left the car in drive, did not manual shift. 969 mileson car. BONE STOCK (at this time)
60 ft 2.2177
330ft 6.1947
1/8 9.391
76.66 MPH.

Car seemd to really start pulling in high gear. No doubt the 3.06. I hope to get some 1/4 miles times soon. First time down the strip since super stock in 1983. FUN FUN!!

www.wallaceracing.com converts 9.39 / 76.66 to 14.67 & 94.98 in the quarter mile

There was a guy on Moparts a couple weeks ago who actually sold his new Challenger because it was only running 101 or thereabouts, and then complained because he lost $9500 when he sold it. There does seem to be a wide variance in performance of the SRT-8's.

The car companies can talk about close production tolerances all the want, the the power out puts are all over the place. I have dyno tested bone stock LS1 GM cars from 275 rwhp to 349. LT1 cars from 225 rwhp to 302. Have seen virgin A4 LS1 cars run everything from 14.20s to 12.80s here at Tulsa. One freak bone stock manual trans 2000 Camaro SS (except the PCM tuning) makes 349 rwhp and runs 12.30s. I have a customer in Houston that ran 11.55 with his A4 2002 TA, never had a valve cover off. But, some won't even go 13s. I don't doubt Ford and MOPAR are the same way.

How many have had to work on this late model "FOOL REJECTED" computerized trash? I cant even SEE the spark plugs on the passenger side of my '91 Corvette much less change them without cutting the fender and A/C box off with a chain saw first. Give me an early model carb/non-computer car anyday. I used to race a '69 Corvette and at least I could work on it without an electronics degree. No wonder Detriot is bankrupt.

I do. All day, every day. They are faster (not your '91 Vette, but the newer stuff), cleaner and use less fuel to do it.

There we go bangin on Detroit like it is the fault of the automakers that a-holes like the commander in chief want 300 mpg next year or else. Why do you think our current domestic automobiles are a complete mess to work on. Because theres so much stuff jammed into them for the emissions and fuel economy not to mention the can't do without items as power mirrors, GPS and other options that generally suck. Ever wonder how a vehicle with plastic fenders, hoods and door skins could weigh 3700-3900 lbs? The whole thought process is *** backwards. Mr. Wright-you bring up a valid point about the inconsistencies of same vehicle output-always baffled me how that happens.

Just remember that alot of our politicians drive foreign cars. Is that sending us message or what!

I have had several new ls1 camaro's bone stock down to the paper filter run 12.90's at 110, 6speed cars. A simple gear change and sticky tires we've gone 12.30's at 110. The ls1 to me is an incredible engine and it flies. The new mustang and challenger are very impressive as well. The new camaro seems like it is going to be very quick too. I can't wait to see a new camaro stocker!

Sounds reasonable. In '94 I bought a new 25th Anniversary T/A w/ LT-1 auto trans and 3.23's. Bone stock I got it to 13.96 @ 99.6. Never could break 100. There was always a few others at the track that were also stock and there's were usually .2-.3 slower. They all doubted mine was stock.

I agree on the LS1's. Ive never driven anything but a 5.3L truck but for what it was, I was impressed. A friend of mine just bought a '06 Z06. He's foolishly said I could take it for a spin. Can't wait!
