First Things First
 

Whats is the first thing you plan on doing to the engine of the new challenger when you get one

RE: First Things First
 

letting it break in...;)

RE: First Things First
 

Not a thing. I think the only thing I would want to change is the exhaust, so I can get that nice low rumble. But that is it.

RE: First Things First
 

As long as they keep the K&N air filter like they have in the pictures. Then I would plan on doing nothing.

RE: First Things First
 

I agree, too, also, as well.

With the current setup, no modifications will be necessary to the engine or intake.

But we'll have to see how the exhaust is. If it doesn't breathe well or isn't low enough, I'll have to adjust it. I wonder what the idle speed will be set at... :eek:

RE: First Things First
 

this car will have to sound good.

RE: First Things First
 

i would have to see things like the exhaust manifolds..to see if headers would be better..and how the stock exhaust sounds/flows...

RE: First Things First
 

SUPERCHARGER at about 5000 miles!!:D

RE: First Things First
 

I'm gonna open the hood and just frickin' drool!

RE: First Things First
 

MAke sure to clean it up before spotting.

RE: First Things First
 

I think Dodge should come out with a HEMI head for the viper 8.0 V-10 and put it in the challenger.

RE: First Things First
 

hmm..that would make the price so ridiculous that it would sell worse than the viper..

RE: First Things First
 

It would also require a larger engine bay which adds weight and length to the car. A supercharged model would be wiser if they wanted to go 600+ hp. Also, if they were going to make a HEMI V10, they should scrap the LA/Magnum V10 and base a new one off of the new HEMI small block because the cost to build the HEMI engine line is significantly less than it was to make the LA/Magnum V8 engine line, which the Viper V10 is based off of. That is probably the real reason why they replaced the 318/360 or 5.2L/5.9L, because the crate engine 360 is not by anymeans weak (380hp & 410ft-lbs of tq). BadStratRT is correct that the price would be redicilous, and would be a bad idea to pursue. No offense AwsomeSpeed, but it just wouldn't work.

RE: First Things First
 

if it is 425hp as placed in the other SRT8 vehicles, i see no reason why you couldnt tickle the 600hp range NA...

first, get the cats off, and get a nice set of headers...i am not familair enough with that intake manifold to know what could be done with it, but figure a bigger TB, and better cam, as well as some sort of computer timing advance, or "chip"...seeing as how in the charger/300c, the 6.1 has dyno'ed to mid 400 range at the crank, 500 should be fairly simple, unless they squeezed everything that they could out of this, which i doubt.

RE: First Things First
 

Add 8psi of boost, intercool it and you're at 600hp for sure. I've started discussing the possibility with the best SC shop I know of. PSE in CA.;)

RE: First Things First
 

i was thinking maybe one of those henessey kits like they have for the 300c/charger/magnum

RE: First Things First
 

How about one of the HEMI crate engines? Like the 528 or 540 supercharged HEMI![sm=gears.gif] That would be fun having +900hp, if it would fit!;)

RE: First Things First
 

eh...forced induction on a factory NA car is only breeding greed..."8psi is fine on stock internals"...then it isnt anymore...that the engine becomes a paper weight...:D

RE: First Things First
 

900hp?! jesus! :( so beautiful i wanna cry!

RE: First Things First
 

Here is a link with the info on the supercharged 540 HEMI crate engine. http://www.mopar.com/muscle/whatshot1005.htm

RE: First Things First
 

I don't think I'd touch engine, assuming functional air scoops make it ot production. The exhaust manifolds are essentially factory headers, much like the original 426 had, see little gain in aftermarket headers for the work.

I would probably "tweak" the mufflers (more aggressive) and most likely swap rear end gears. 4:10 w/ a 6 spd should be just SWEET.

RE: First Things First
 

FIRST: If the factory doesn't put in synthetic oil, I will change to that after about 100 miles. Then if the exhaust manifolds make it as on the concept, then fine. But I bet there will be gains to be made by aftermarket headers. Hooker, get ready.

RE: First Things First
 

OK, I agree we must have Mobile 1, then the SC...;)

RE: First Things First
 

If needed in this order:

1. Muffler

2. Headers

3. Cold Air kit

4. Reprogram the computer

5. After 20K miles then maybe a supercharger (Rotrex is a new technology I would look at)

Honestly, I bet most of this stuff is high enough performance it will not need changing but they may cut costs.

Like they did with the Charger........made it a 4 door. Gosh, can you imagine a 4 door Challenger. If that gets announced

I will leave the forum for good. What a horrible thought? I must be deranged. LOL!!!

RE: First Things First
 

The very 1st thing I will do to my Challenger for performance is to add a mufflers ala Flowmasters Series 40's unless it is determined the the air input is limited by too small of a filter (in the pictures
the surface area appears to be adequate but not sure).

Other things to consider would be a throttle body change. Gosh I would hope the headers and exhaust pipes are adequate.

An underdrive pulley system and maybe reprogramming the computer.

Only after the engine is free breathing and all restrictions have been removed then I would consider a supercharger.

I would make sure that every modification I made would still be somewhat reversible to factory stock condition(like keeping the original mufflers etc.).

These are just some things I would consider.

RE: First Things First
 

i have never messed around much with superchagers but if you added a super charger to the car would you be tuning it up all the time?

RE: First Things First
 

no

RE: First Things First
 

first pay it off then Supercharge it then maybe nitrous. then run it on a track and see what crazy times it will get[sm=nxsmile.gif]

RE: First Things First
 

I know alot of you guys will probably be getting the series 40 Flowmasters but i was thinking Cherry Bombers Glass Packs, low rumble is nice but id still like to here that engine SCREAM!

I retract my last statement, Flowmaster will be much better

RE: First Things First
 

Wait a few months to break in and let some nicer products come out...

At which point I'll be removing any cats., possibly installing meth. injection, and addting picking up a tune if there are some nice ones out there (piggybacks or otherwise)

RE: First Things First
 

Here are a few ideas I can offer. We took a Dodge Magnum with a 5.7 HEMI and wanted to see how much improvement we could make with just bolt on parts out of the Mopar Performance catalog. Here's what happened; Stock the car was good for 14.30's@ 97mph. We added: Full length headers/cat pipe and cat back exhaust; CAI; mild cam; CNC ported 5.7 heads, upgraded converter and some PCM tuning. End result: 13.10@111mph on real street tires @ 4400pds w/driver. The car has more in it with some additional tuning and better tires. Driveability is very good and the cam has just a slight rump to it. If I were to make a suggestion as far as order of parts I would say: Exhaust first, CAI second, tuning 3rd, cam 4th and heads last. If you don't want to get into the motor, exhaust and CAI will make a nice seat of the pants difference. These are the 2 things most people do for a quick bolt on. The HEMI likes to breathe so anything that eases this will make gains. Besides a power gain exhaust and CAI will actually help your mileage out a bit(if you are driving it civil that is). A fella on Moparts has a 2007 Charger SRT-8 with exhaust, CAI and a tune; Ran a best of 12.20 @ 113mph. Of course this is with the 6.1. The Challenger will be lighter by about 250/300pds so this will help. Cool thing is this is with NO nitrous/supercharger/etc. This is excellent performance taking that into consideration.

RE: First Things First
 

Were all these changes done with a stock ECU? No computer software or hardware additions/changes?

RE: First Things First
 

Confession time. I knew the AI was "Air Intake", thought the C was for controlled. Cold. Ah.....

Begs the question on the scoop on the chally and whether it will be for engine cooling or air induction?

KVN?

And yeah, what about chips?

RE: First Things First
 

To answer the question, yes the PCM had custom programming. If you change the cam that's when it becomes more mandatory than optional. In most cases a CAI(Cold Air Induction) and exhaust will not cause any issues and therefore these are the most popular options. Work on performance calibrations is being done for the car but I don't have a timeframe on that. Don't be surprised if there isn't a "Stage" type kit similar to what is out for the Neon SRT-4 but obviously specifically for the Chally. I run a Stage 2 kit on my SRT-4 and have put nearly 40K miles on it with no problems and a nice gain in performance. Most of the performance parts(especially late model fuel injected) are being designed to offer nice powergains/reliability/durability and driveability.

RE: First Things First
 

Now it appears the air scoops are not as "functional" as the original concept structure had them where the hood scoops fed an under hood ducting into a large K&N filter. Now, they appear to be nothing more than "heat extractors" especially since air box is sealed. However, We've also seen they are saying they will have functional cold air kits & hood available through Mopar parts?? Could this be essentially the concept hood and air element?? We'll have to see...:eek:

RE: First Things First
 

Please define the term "tune" as used here. Im thinking a programer or ?? When my 09 SRT8 gets here in a few months or by spring, I am going to do a Mopar CAI for sure and by then the situation with headers and exhaust should be a little clearer. I wonder how a larger throttle body would affect this situation. Im not really interested in going into the engine,, just bolt ons that can be undone. Id like another 40-50 HP if possible. At least enough to take a GT500 easily. Since its close now that should put it over the top.
Now about those Roush Mustangs,,,;)

RE: First Things First
 

How about a Zex wet kit? All bolt on/in and at a 50# shot, should be very safe on the motor - if you run a slightly cooler plug (okay, 16 slightly cooler plugs).
That should give you the modest HP increase you want for around $1000.00.
:eek:
