Dynamic Racing Charger up-date

[FastMatt]

As most of you know our Charger Dynoed 346 RWHP with Our stage 2 heads, Comp stage 1 MDS cam and Dynatech headers, magna flow exhaust.

We just finished today removing the Stage 1 cam, removing the MDS lifters, MDs solenoids from the block and going to the Comp stage 2 cam. And so far all I can say is WOW, The car is much faster. After start-up the car did the same thing it did with the stage 1 cam, it had a hard time idling but after letting it idle for 15 min, then driving it allowing the ECU to re-learn the car is running like a champ. and has STILL not throw ANY codes!

I put about 10 miles on it earlier, I'm going to drive it 30 or so miles tonight and see if it throws any codes. I'll keep you up-dated.

I'll most likly take it to dyno in this weekend.

[RTjunkie]

Oh man I wanna see the S3 cam numbers. :D

Hell, these too!

I'm still quite undecided what I wanna do to mine.

[jasonface]

This is gonna have to be my next mod. I was thinking I wouldn't get into the engine before the car was 6 months old, but I can't resist. One question: Here in Ca., do you have any idea if either of those Comp cams will pass the state smog check? I know their not technically legal, but as long as you can pass the sniffer test you're cool.

[broc2238]

Very interested in seeing these new numbers...For the sake of time, would you mind posting up the cam specs of both cams that you threw on the thing as well as the specs of the stock 5.7L cam?

Thanks Matt!

How's the sound on those Magnaflows? How do you think those numbers would change with the Brylcream instead?

[MadC]

Ok Matt - You've had enough time :)

Any codes, or anything funky? How's the idle? Is it really that much faster than your already fast 260?? Inquiring minds wanna know.....

[FastMatt]

the Magnaflows sound very good.


Any of the aftermarket cat-backs are going to be within 2-3HP of each other for these cars, at these power levels.

[str8frmw]

Matt lets see an in car video!So we can really see what these things do with those upgrades.

It threw 2 codes last night, Bank 1 and bank 2 "to rich" codes. I expected this. That’s from the fuel trims maxing out at idle. I cleared them and so far thy have not come back, but I suspect thy will. This is from the lower vacuum at idle, the ARC-1 should fix this by being able to alter the MAP signal that the ECU gets.

And yes the car does feel quite a bit faster then it did with the XFI260H cam, and I have a well tuning butt dyno.

Well the reason I mentioned the Brylcream was because that's the mod where you remove the mufflers and replace with pipe and then leave the resos on. I was just wondering if there's any real performance reason to get a catback on these cars since I hear they already flow very well.

[Shakin]

with the stage 1 cam, did the MDS still come on?

[FastMatt]

yes it did, for over 8000 miles never missed a beat.

Dan, The Brylcreem mod will perform as well or better than any aftermarket setup......

I should probably start a thread to ask this but, so then why do you and others pay the $500-1000+ for the catbacks? Is it cause you wanted a different sound than the Brylcreem? Or bragging rights of saying you've got a Zoomers/Bassani/etc catback?

[chargershed]

MOST LIKELY!! The aftermarket exhausts are more "tuned" for sound than the
brylcreem...especially at idle... if you want the traditional muscle car sound at idle than an aftermarket set up is the way to go... performance on the "cheap"... brylcreem hands down....

I tried removing the resonators first - but couldn't stand the drone! And although most guys will say the brylcream doesn't drone, I don't believe it (they said removing the resos didn't drone either). My Borla 112's give me the best of both worlds - great sound when hard on the gas, but very mellow, with hardly any drone when on the highway. I also have long tube headers which will make my car more likely to drone with the brylcream or tuna boat mods, than a car without the headers.

[MadC]

Bump!

Any new news on this one Matt? Interested to see how your numbers compare to the 260 numbers.....

[extremez97]

just aquick question, what have you used totune for cam, heads exh, headers, etc. just curious bc i cant find anything to tune my car with?

Super chips tuner

[extremez97]

does the superchips have enough adjustabilty-control to compensate for boost?

[extremez97]

are you using a map alreadyset with superchips or have had a custom tune downloaded?

[FastMatt]

Dyno Up-date

The car Dynoed today at 367.7 RWHP, and 383.7 RWTQ!!!

That’s with the heavy 20" wheels on the car.

That’s up ~96 RWHP from the cars base line pulls at 272 RWHP with just a magnaflow Exhaust.

Now that my friends is a BIG power gain from heads/cam!!!

I also installed the Split second ARC-1 fuel controller on the car today about 1 hr before heading to the dyno. With the ARC-1 on the car and set-up, the car idles prity close to stock. About the same as the car idled with the comp stage 1 cam in!!

I'll Get the Dyno chart posted up as soon as I can get it scanned.


The power does no drop off AT ALL all the way to 6250rpm, the car has one if the flattest TQ curves from 2700rpm to about 5300 rpm I have ever seen.

[FastMatt]

For boost? we are not putting boos into the car..... yet:)

[juanitorus]

i will tell you right now matt, you are the motha f*ckin man. provin the hemi's true power w/o turbo, s/c or nos, all engine baby. keep it up.

[kennyR/T]

maybe he ment boost in power

[Spali32]

Looks like you need to update your signature again now, MATT.:grin: :grin:

Going from 272rwhp to 367rwhp is very impressive on the 5.7 Hemi. That's right at or over the OEM 6.1 Hemi rwhp. Awesome!!! I'm impressed.

[jay2puff]

Yes I do, But the track by me (Roswell) runs it's last race of the yr on the 13th and I cant make it that day. I'll most likely take a trip out to San Antonio some time soon with it. ( over a 500 mile drive)

[NOLAchargerRT]

Need more money nnnnnow. Thats amazing hp #'s. Any idea when you'll have the stage 2 cam available to purchase, and if it can be added to the heads/cam deal you have going on?
Whenever you get back from the track in San Antonio and get us the 1/4mile times, also let us know the MPG. I know I didn't buy it for the MDS but I just want to see how much this cam guzzles, going on a road trip.

It's already an option in the Heads/cam deal!

[NOLAchargerRT]

Wow ok, because I checked the site and they only list the KRC cams and the XFI 260 cam, which is the stage one. The 268 is stage 2, and the 273 is stage 3, but i haven't heard of any 5.7 getting the stage 3 anytime soon.

My bad - I think you're right - although I don't believe the 268 cam is much more money than the 260 - if at all.....

Matt, do you guys work with any speed shops in the east that would handle the install? I am in Georgia and dont think I would feel comfortable putting those in myself and NM is just to far to drive.

The heads/cam install on these cars is quite striate forward and easy of a install (as heads/cam installs go on late model cars). Heads/Cam/Headers install takes us 2 days on a Hemi.

Matt:
1. You are using the SCT on these cars? Is that "good enough" to handle this cam and heads or does some other form of tuning need to be done? They dont recommend the SCT with headers as it is. Is their level of tune ok with the cam and heads?
2. Assuming Mr. Pamoena does his job correctly is there any reason why I can't expect to use a car modded like this as a daily driver - and by that I mean conditions such as heavy traffic in the summer heat etc.? Or am I expecting too much?
3. Is the tranny up to the task?
Thanks

1) The original Concern with the Super Chips was that the engine would run lean. If your read the boards this have proven to be a non issue.


2) Heads or Cams should have little effect on the drivability of the car in daily use ecept for potentially idling different.

3) Common sense should tell you any drastic HP increase will put a greater toll on a transmission. Obvioulsy it hasnt blown out that of the test car but long term wear is something that you would not know till after several months or years of use as with any mod.

Just my opinions.

1. I've read the boards and this seems to be a non issue. However, I'm wondering if these mods will create this problem or another and other tuning is needed.
2. Good because you're only ecouraging me :)
3. The tranny may be engineered to take more power then the stock 5.7 is delivering anyway so this also may be a non-issue. I was curious about
Matt's opinion as to whether the tranny is up to the task or is it a foregone conclusion that it is not going to make it long term. Just trying to plan ahead.

[ChargerPLAZ]

One more though, I was looking at a limited slip differential. Is this a worthy upgrade for the money it would cost?

[kalbc]

Is there anyone on the board who has installed the heads?

[Hemiready]

I think so. I'm sure they'll chime in. I know some have done some of the other heads that are avialable as well.

[extremez97]

when i mentioned boost i ment for turbo or supercharger. i read somewhere that people were having problems with the way gs motorsports AIC was working-all the fuel was going to the back of the intake not creating the correct distribution of fuel for the boost. im interested in install bigger injectors for my turbo'd hemi magnum and im wondering what is available for tuning the car for the inj and boost. didnt know if matt was getting a custom program from SCT or it was working fine with perm tune and split sec controller??

[MadC]

I'm wondering if the SC wasn't enough to handle this cam - hence the need for the Split Second.
Matt - is this the case? Is this cam pushing the limits of the SC, and better with a flash, or Split Second?

Yes, with the comp stage 1 cam thats all I use, cars run grate!, with the stage 2 cam I also piggy back in the ARC-1.

No problem with it being a daily driver, This charger with the Comp stage 1 cam, Heads, headers, Exhaust, SC tuner, and K&N was used as a daily driver for over 8000 miles befor the stage 2 cam was installed, and is now going back in servis as a daily driver with the stage 2 cam.





3. Is the tranny up to the task?
Thanks

Same tranny goes into the SRT-8's and it holds up just fine with mods to them, heads, cams, NOS, Superchagers. Not to mention the 700+ ft/lb of TQ Twin turbo V12 benzes....

[FastMatt]

I only put in the ARC-1 for help with the idle. On the Dyno I leaned the car out even more then the SC was tuned for with the ARC-1 and gained 4hp and 10 ft/lb of TQ.

still running like a champ.

It if you let it sit at idle for a LONG time it will throw a misfire code.

Have not figured out Mileage on it yet with the new cam.

THe ARC-1 took all of about 15 seconds to set up. If you just want to fix the Idle with it you don’t need to know A/F, just what ever you take out on the "LO" dial Add back in on the "high" dial to make it the same A/F after you go off idle.

Fast Matt..I am considering the stage 2 non mds package. I already have the LT/FF cats. If I were to head over to your place what would be my out the door cost for you to hook me up. You can PM me if you want.

It was getting about 22-23 on the highway with the stage 1 (with MDS).

not shore yet with the stage 2 and no MDS, but we are at ~260miles so far on this tank full and it's still over a 1/4 tank. Dave is going to be taking a long drive in the car across TX here next week, so he can give up a full report on the MPG.

the heads/cam are $1999
the Dynatech headers with cats are $1099

If you don’t mind a short drive to NY, there is a very good shop up there that I know of that can do the install for you. He even has a in house Dyno if you want some #'s before and after the install.

Or you can bring the car out to us here in NM.

[DeamonCharger]

So....Heads/cam w/ valves/springs, and all the goodies are 2k, + core charge? Is that for our 6.1L too? Also....for my own paranoia...what reassurance do I have that these are 6.1L heads. I know they are hard to get from Dodge, so I am a bit worried that they would just be 5.7's ground out.

[GLHS837]

J, for a closer to home solution, contact 2QK4U, he's had all his head install work done by Jeff at Insane Fabrications in Owings. Nice thing is that Jeff owns a 300C SRT-8 himself.

LOL, that’s funny, but A good question I guess.

There are quite a few differences in the 6.1L heads that makes them distinguishable from 5.7L heads. On top of that 5.7L heads ported can never be made to flow as well 6.1L heads ported can. There are quite a few differences in the castings. We would have to be out of our minds to try and pass of 5.7L heads to go on 6.1L cars.


So in short, of you order heads for a 6.1L you WILL get 6.1L heads.

[RobAGD]

One thing you do have to watch is that a lot of shops are using truck heads for thier cores and they are close to the same as the 5.7 car heads with one kinda major differnce, the boss where we bolt the I think power steering pump is not finished or tapped for the bolt.

The early 5.7L truck heads dont have the EGR port. The newer ones may, but I'm not shore I don’t work on trucks. But the heads we use are CAR heads not truck heads.

Just install and go. Now if you want a unit that you can smooth out the idle with as well as tunes the A/F and is very easy to use check this out.
