Discussion in 'New Challenger, 300, Magnum, Charger' started by hemi_magnum, Nov 21, 2005.
...and something like 75 more horsepower, and the available manual trans is a 6spd vs a 5spd.
I think the R/T is going to be quite a deal, actually, when compared with the Mustang and the late sorta-lamented GTO.
I have been planning to get an SRT this fall, but I may hold off -- my kids are lobbying for a convertible, and the R/T might be good enough to convince me to go that route instead.
Here are some of the SRT engineers' answers to the questions posed on last night's very informative Chat Session (there are some "gold nuggets"):
We wanted the Challenger SRT8 to have its own personality and driving experience, not just looks. We intentionally tuned the suspension to have a unique, slightly softer muscle car ride with different spring balance due to the different wheelbase. The shock tuning is unique, too. What we found was that we could make it ride much better than we expected and still keep the handling. As a result we retuned the '08 Charger and 300C srt8s to have a better ride. The Challenger SRT8 has its own exhaust tuning as well.
There was a ton of tweaking, but it was not necessarily hard. In fact, it was nice to take another look at the platform. The more we get to develop a platform, the more refined the cars get, ala the Porsche 911.
The '08 Challenger has the suitcase and resonators, although it sounds different than the Charger. The '09 different tuning due to the manual trans which the '09 auto will share. The backpressures are all the same, which is very low and barely legal. Mopar will have stuff, but it is not announced. Sit tight.
The Challenger SRT8 brakes are identical to the Charger/300 SRT8, slots and all. '08 Challenger SRT8 and '09 Charger/300 SRT8 get knockback mitigation.
The ducts in the hood do not go to the engine intake. They would be a restriction. The scoops have been fully water tested.
All of the 09 SRTs will get the new Challenger diff. The new diff is an heavy duty aluminum body limited slip with various ratios, 3.06 for the automatic, 3.91 for the manual transmission and a 3.73 ratio for the manual base car. The internal gear sets and carriers are interchangeable for the new housing but not with prior differential models.
The 6 spd manual trans (based off the Viper manual) has internal improvements (triple cone synchros and more) coupled with the Sachs dual disc clutch is an awesome package.
The all-new Tremec TR6060, which was developed for the Viper, just came along in 2008. It was a perfect opportunity to put a modified version of the same updated/improved TR6060 Viper gear box in the Challenger. Also, why are you just now coming out with a true limited slip differential as opposed to the brake limited diff in the current lx's? Same answer as above... new car... new opportunities to improve performance. That's what you want, right?
The Manual is a 6 speed and has 5 and 6th are both overdrive gears there only to help fuel economy. We match it to a more aggressive final drive ratio for a balance yet aggressive launch. The MTX will have a reduced gas guzzler tax and we are in final certification with EPA as of today.
The Challenger SRT8 and 300 SRT8 wheels are 6 pounds lighter than the Charger SRT8 and the Magnum SRT8. (Is that stamp a change in manufacturer or just a newly added stamp?) Same weight...newly added stamp!
255 F1's hit the splash shields at full turn and the fend lips at full jounce. You can probably get away with running them up front if you drive like a wuss. No complaining allowed, though. The RS-A's need to be snow capable which dictates the compound. The compromises the performance in other conditions. The RS-A's actually have more aggressive sidewall construction than the F1 to compensate for the compound and tread differences. We made them as close to each other as we could. Most people love the 20's. You are welcome to put 18" wheels on if you want.
Don't believe everything you read. Our Dynamics guy challenges you to show up in Michigan in your car with whatever aftermarket tires you want in the same size as stock and we'll do a runoff on all our tire performance criteria. The Goodyear F1's will win. You want more life, you'll get less stick.
Does the 6.1 now have an oil dip stick so that we can check the oil level?
The 6.1L has a dip stick.
How theft-proof is the ignition lock?
The Challenger has a digital key.
Is it true that the computer learns your driving habits and the engine will not “come alive” if you drive too conservatively? The trans controller and the engine controller both adapt to the car more than your driving habits. It compensates for build and system variables of the components to torque and time events.
If you have tuned the SRT for maximum performance, why are owners buying tuners like Predator and Diablo to gain more hp? I would not spend the money as most of the aftermarket tuning packages we have evaluated may put spark in or take fuel out of the wrong places and create durability issues.
What you think of the new high energy spark plugs - i.e. Halo, Pulstar and like that for improved performance, better fuel economy and reduced emissions? Snake Oil
If the general public believes that the calibration engineers leave any ponies on the table when competitive pressure around Detroit to one up the industry are so politically charged, they are wrong. This is a bunch of racers and we want always to win. If a change is made to hardware such as long headers which we could not certify for emissions or noise, Fuel air and spark need to be modified. We are also sensitive to the cost of our vehicles and spec the parts to meet our functional objectives. Some components may not like being pushed harder.
The Caliber SRT4's have spacers because they are lowered much more from the regular Caliber than the SRT8s are from regular LX/LCs. The spacers are there mainly to get the Calibers off the clamshells in the plant. The Challengers shouldn't be getting damaged any more than 300C and Charger SRT8's. They have the same clearance and approach angles.
The ECU adjusts boost to generate the requested torque at a set of given conditions. The boost limit will also vary according to the ambient conditions.
Current road tests of the 2008 Challenger SRT has it consistently doing the 1/4 mi. in 13.3 sec. and 108 mph. How much faster, will the 6-speed manual be in the 2009? Their so close that were actually reporting the same performance numbers, however,top speed is a little higher on the manual...and you should see fuel economy improvements- 1 mpg.
Don't know that level of detail on the R/T. They stole our seats out of the 300C SRT8 (Chargers, Magnums, and Challenger SRT8s have stiffer bolsters). We doubt they made a new hybrid seat out of the cheap bottom and good seatback.
The suits and bean counters won the fight on that 4 spoke, and we fought for a new wheel. The armature tooling and impact validation of a new wheel is quite expensive (like 7 figures), though
Is the new re-formulated Mobil 1 0W40 oil still ok to use on my 2006 SRT8? It will be fine.
I am referring to the Sebring 'vert, not a Challenger.
I'm not ordering mine till late October or early November.
Now this 3.5 SE thing.
Can it do this at 4,000LBS: 340 V8 1/4 mile 14.8 @ 96 mph?
If so Dodge should seriously consider a Challenger Rallye, kick up the sporting looks and tune for some more aggressive handling. Listen up Dodge!http://www.mikes73.com/73challenger-rallye.jpg
I'm still buying an R/T though.
Challenger SE= 0-60 7.8 seconds; 1/4 mile= 16.0 seconds (vs R/T 5.5 & 14.0).

Mygig $1,240 or $890 with AY2 package
SRT option group II $1,045 AY2 Kicker Sound Group
Plus the 6 speed gets $1,700 GG tax/1 mpg better fuel rating
The above list is fairly accurate, GG is $1751, and also listed (page 7) is a group option "guw" for auto dimming pwr htd f/away drvr mirrors, but no pricing, maybe later availability???
Also, the way they have the MyGIG option listed it's; MYGIG MULTIMEDIA SYSTEM------1240
W/ NAVIGATION-----------(w/AY2) 890
At first glance it looks like the MyGig is 1240 then if you want the Nav it's an additional 890, however with that little "w/AY2" in there it makes it look as though the whole MyGig option is 890 if you get the AY2 group (1045 ), anyone else notice how that looks? ( it's on pg 6 in step 3)
It's funny with supposedly all of the units that have been built and supposedly shipped, in this region only 2 maybe 3 dealers have seen any of their units, everyone is still waiting, yet it seems other parts of the country are having no problem getting them???????
Hey oh2o, where ya been? I was wondering the other day why I haven't seen you post here lately. I was hoping you didn't get canned for letting out company secrets
In the case of the R/T, I hope that's for the auto. Otherwise, those figures suck.
Tommy Boy: I wouldn't worry about the numbers, I'm sure we'll see privately-owned cars run faster than that as with the current SRT's.
Richard Petty edition Challenger #43 - Real pics of the car being delivered to the winning bidders!
Came with a seperate hood signed by both Richard and Kyle, too cool!
Wow! That blue is a lot better looking on the real car than on the promo pics. Nice.
No it does not.
Funny that that question should come up again, HemiCuda is correct. I asked it a while back and Bob Sheaves provided an informed answer...
14.0 1/4 mile is good for a 4000 LB car. Its about the same for the 1970's 440 that did 14MPG. If you want to go faster mod it or get an SRT..What bugs me is the price tag, but I'm from a time when the V8 option was $200.
According to the engineers, the SRT8 auto and manual are so close that they are using the same performance numbers. This appears to also be the case with the R/T models, at least that's what they're reporting so far. Typically, these numbers are conservative, I'm sure you'll find reports of R/T owners easily getting into the upper 13's with stock vehicles.
Sorry if this was already posted.
Stock Daytona's will run 13.9-14's. No doubt that Dodge has been conservative with these times.
