You need a night shot to see all the cool lights..LOL

And ya i never heard anyway say the mustang interior was overdone. Most find it cheap.

Exactly.


1) You are acting like the R/T and SRT-8 Challengers don't look almost EXACTLY like the base model. Now if you just like the way the Challenger looks more than the Mustang, that's fine... but that "it looks like the base model" reasoning is ridiculous.
2) The car is very fast for being as heavy as it is. But where you would rather drive the big car with the big engine, I'd rather drive the car that weighs 600lbs less and is a ****-hair slower in a straight line.
450rwhp with bolt-ons big deal and some of the ones i have seen aren't even doing a pull in fith gear..cough cough. the 392 has dynoed over 430rwhp completely stock..What in the hell do you think they are gonna do with bolt-ons let alone a cam and heads?

So you know if they dyno in 5th gear they would be higher in the 5.0. 5th is a 1:1. None of the rest of the gears are. This has been proven. Mine was fynoed in 4th cause that what did my base pull in also.

Some shops have did this. Dyno in 4th stock then 5th to show bigger gains.

And from looking around on the challenger forums seems most are around 400ish bone stock. Dyno's can read high though/. Few people have posted their 5.0 went 390-400 stock. Which would be impossible without a happy dyno.

You are correct about hp numbers,but your torque numbers would be higher with a fourth gear pull..

From what seen all was higher in 5th. I will be retuning here soon and I will Test this again. I am going to a aggressive dyno tune instead a mail order tune from Blow By Racing.

The lowest 392 dyno was in the 420rwhp range..big difference from 400rwhp.Also look at the torque it makes.

These new 392's are making some very impressive power stock. Yes they're much on the portly side, but Mopar has always done a good job of offsetting weight with horsepower and torque. This one is no exception. New Mustang and Camaro owners better be on their P's & Q's cause this new SRT-8 is no joke!

430rwhp verified by poster

And check this out, this one's bone stock w/ just a 60-shot and some higher octane solely to keep the timing in order (no tune). 470/535

Wait until guys start throwing the basic bolt ons like headers, midpipe, cold air, tune. God forbid a nice heads & cam package on top. Can you say "Tail lights".

Torque will read higher with a fourth gear pull..The higher the number on the gear ratio the more torque it will have.

I think people are underestimating them because they are heavy,but the power they are gonna make with bolt-ons are gonna leave people speechless..

We will see. My numbers will be a little effected as well with the 4.10s and 295 Drag radials I run 24/7.

The new Chally is making great power. And I think it will shine stock to stock on a roll race with a 5.0. On the track I think it is more of a drivers race. Its issue is its weight. Roll will help the weight not be as big factor till higher speeds. What gearing comes in the new SRT8? Actual weight?

Both having bolt ons it gets more interesting. The great thing about mustangs is there is so much already out there to drop 200-300lbs really fast. Ask me how I know.

Let me just say this..You have a sick *** car and i would rock the hell out of it,but i think the new challenger is gonna put a hurting on alot of cars..I will be test driving one in less than two weeks,I have a choice of an auto or manual..Just wish i had somebody that could drive worth a **** so i can run the gto against it for a comparison.

I think people are underestimating them because Dodge is traditionally an under-performer and over-priced. No question the Challenger is the best looking muscle car out there.

Am I the only person that thinks the 392 is making **** numbers? Yes, it is making great numbers compared to the SS/5.0. But it is however a 6.4L motor making 470 HP. The Boss is making 444 HP with a 5.0L. I'm sure if Chevy made a performance V8 model like the Boss and SRT that they could pull off equal numbers to the SRT.

For $43,000 on the SRT-8 you had better be buying the car based on it's looks because in the performance department it's lacking compared to the competition, $ to $.

Weight is not really an issue tho. Their making close to 50whp more on average compared to what we saw when the Coyotes first came out (360-375) and more torque peak and under the curve. They're running similar if not quicker average 1/4 mile times too. Plenty of engine displacement. And 535lb/ft w/just a 60-shot and nothing else is crazy.

If our dealer has when when I hit home in about a week I will test drive it.

My car is just getting started. I have a lot of plans for it. Biggest thing is just deciding for sure what way i want to go. I also know there is always something faster.

50whp isn't nothing really. When weight is 500lbs or more depending on model of 5.0. That 50whp is right out the window.

From times seen on Challengertalk/challengerforums they are running very close times as each other. Some 12.3-12.9's just like the 5.0s. Comparing best each the 5.0 is ahead by .15/3mph. That was with the SRT8 on DR's and the 5.0 on street tires. 12.1 with just tires on a 5.0. The weight is making a bigger factor then the 50whp. Also a few 5.0's have hit 380whp+ stock.

Both are getting faster stock with more people learning to drive them. Which happens with all cars.
