Many of us plan on buying a Challenger SRT (either 6.1 or 6.4) because we want the baddest one available. We all know that for about $7,000 more, and SRT comes with 425 hp, upgraded interior, handling package, Brembo brakes, and "elite" status, etc. But how much faster is it than an RT with the Road and Track option (350 hp)?

For everyday driving, there is not a huge difference. However, when you get on it, the SRT smokes the RT, especially after 70 mph. See the following chart from Car and Driver:

I'm always looking for the most bang for my buck. It would all come down to total cost. I don't plan on racing it but I want the max HP within a reasonable $. Being no costs have been officially set I'll have to see what the deals are when the time comes.

 

I feel the same way. The RT is still a great model and I would consider buying one.

However, if I can get an SRT for a reasonable cost, I will go that route. Some owners of Charger SRTs have reported that they were able to buy their cars for only $3,000 over the cost of an RT with the Road and Track package. It will pay to shop around and even buy out-of-state from dealers who specialize in SRTs.

Time will tell as to the demand of this car and what the dealers will be asking. I intend to watch the prices and dealer inventories of the 2008 Challengers closely and use this knowlege to buy in 2009 (when the 6.4 should be offered as an SRT engine).

 

I believe you are making a reference to the LX models in these numbers. They may not be the same due to the manual efficiency.

 

RT is fine enough for me!

 

I think it would depend on which way is cheaper. With the gas guzzling tax on it and whatever else may bump it up to an outrageous price, I may just go with a supercharger if it's cheaper. More bang for the buck, and I'm sure they already have them out on the 5.7 so there would be no wait.....hopefully, though designs may have to change for whatever reason.

 

I am only buying one. I want the most BANG! Bring on the 6.4L...I am all in.

I am with you awsure.

I will get the biggest and baddest to the bone Challenger available. Then I plan on making some of my own mods
on styling and performance. Can you spell turbocharger?

 

Be careful with a supercharger. It will void your new car warranty and some guys are reporting that the 5.7 engine can only tolerate 2 lbs of boost before encountering major problems. Basically, it is not beefed up enough, internally, to handle the added stress.

 

They do say that it won't void the warranty, as long as it's not the cause of the problem. Being from what you just said here however, it does look like it would be the cause of the problem. Well, I guess that idea is out. That kind of sucks, not that I had an extra $5,000 to throw around on a supercharger as it is. Heck, I don't even have the SLP Loudmouths, or the Dynomax, exahust that I want on my car now and that's only $400. And had I not spent that on a lawyer for a traffic ticket and court fines, total of $541 I'll explain more if needed, then maybe I would have that exhaust.
