Question:
who is contracted to make the SRT suspensions?
I thought I heard Bilstein makes them.
I want to lower my SRT Caliber 1.5 and want to know if the struts can handle the drop without failing over time due to the shorter travel.
Or will MOPAR be releasing a product to do so?
Thanks.
Thanks 'lil buddie
Wonder if they are making any deals on the C-SRT-4 yet? Surely they can talk about that, can't they
Seems like they should be...how about zero down, zero APR...only 1 more payment on the SRT-4!
Hold on, I'm channeling (your from CA, you know about channeling, right?) an SRT Engineer right now.....
"Money? We have people for that"
AFAIK, no SRT has even had that deal. End of year employee pricing, like I got for my Charger (43K sticker, sale price before state fees was 38,900) yes, but not the financing deals.

I used to own one of the first SRT-4s sold, bought it new in Feb 2003, sold it Nov 2006 with 75K and Stage 3. Now I drive a 2006 SRT-8 Charger.
Why arent there any techs in the philadelphia area that know how to work on the SRT neon trans or car in that matter, i have been working with Faulkner Dodge in Jenkintown PA and they only have one guy that knows how to work on my car and to tell u the truth i dot think the guy can open a coffee can properly, let alone work on my trans its terrible and now they are refusing to do anything else to it after just throwing clutch after clutch in it saying thats the problem (parts warranty) 1st through 3rd is tuff putting in gear they replaced all shift forks and sychros shift cables and clutch after 6 months they wont open the trans up just throw parts at it, what do i do or better yet where can i go to get a second opinion !!!??
I have a couple of questions for the SRT engineers:
1. How exactly does the PCM calculate EGT's? (what are the input parameters).
2. What does the PCM use the calculated EGT's for? (is it just a byproduct calculation or does it actually influence the PCM to change other variables like boost, ignition advance timing, injector pulse widths, fuel trims).
Obviously, noone in the right mind would tune a car based solely on calculated EGT's. But those of us with OBD-II scan gauges are aware of the calculated EGT readout and would like to know more about it. Unfortunately, the PCM is a black box to everyone outside of DCX, hence the question to the SRT engineers.
Thanks!
I'm not saying this is the best way to tune, but back in the day when wideband sensors were uber expensive, they would have a test motor/car on a dyno and run through simulations of running rich and lean under certain instances. Both EGT's and and AFR's were logged. There is a basic correlation that is compiled from this data and the engineers are able to develop a basic table or two that will run safely without the use of a wideband.
One example of this is the old MBC. Most pre 2000 turbo cars can easily be fitted with a MBC for a power increase. If the boost was turned up too much then the car would go boom. No 'safety-net'. The NGC controller does cross checks and even though we are bleeding pressure off so the pcm isn't seeing the full boost amount, if we stray too far off (usually 3-4psi) it will pull timing like crazy and adding more fuel because the EGT's have gone up and no longer correlate with the tables. Most then add W/I to counter the increased egt's to take advantage of the MBC.... does this make a little more sense?

I see no correction in F/A or Timing for a MAX EGT in the NGC programming.
There are some things in there to save the CAT but ADDING fuel KILLS cats so your claim that the NGC would be adding fuel is inconsistant.
What exact process are you reffering to?
Where did you get such an idea?
What would the NCG use to monitor Exhaust temp to induce the Fuel and timing corrections you claim??

Seems like I have a stalker now, the last 3-4 techincal posts I've written you've fired back at me with an onslaught of Q's, Are you testing me?
If you have an areoforce scangauge, in the odbii parameters you will be able to monitor PCM CALCULATED egt's even though there is no pyrometer installed in the car. As far as what the car uses to calculate this parameter, I would guess that the O2 sensors and inlet temps would be used at a minimum but I'm cant say for sure. I would recommend contacting aeroforce and asking them as that is more up their alley.
There is a correlation of egt's and the effective afr that a specific car runs PROVIDED that initial testing has been done with egt probing and wideband testing to develop a motor. This has been done in everything from the oem mass production cars (like the SRT-4) to circle and dirt track circuits. Feel free to do your own research into this as I don't have the time or patience to try to educate you on the subject matter. It's not my idea, I don't tune this way, so I can't take claim to it for anything. I am just merely passing on an appropriate answer that seemed to fit the question.

Hey,, looks like someone needs to keep you honest.
Your post was written as fact when in reality you were only making a educated guess.
Fact 1: The NCG uses the electrical resistance in the O2 heater circut to monitor ECTs inside the CAT.
Fact 2: The EGT calc is ONLY used to save the CAT. It is not used to adjust F/A for performance.
ps I'd rather ask my sister for her opinion than Aeroforce.
new to this site, quick question my 04 srt4 grinds 3rd if driving agressivly and if im driving normal it will pop out of 3rd occasionaly, my buddy recently picked one up and his dose the same, he bought whole new tranny and clutch/fly wheel, any way to fix that grinding? (help) dont want to spend alot of money i was thinking of getting a short throw shifter to see if that would help? whats that grinding all about???

Do you have a warranty? if so use it at the Stealership. If Not then its either the synchronizer or the Retaining clip for 3rd gear Commen problem i just had it happen for the 2nd time then last night my trans BLEW UP! literaly
so i take it a short throw shifter is out of tyhe question? i might buy it and replace the syncro, see what happens thanks alot for your help orangesrt-4

No problem trying to help out when i can. I only know about this because it happened twice. i'm getting another NEW transmission.
my question, can you use a pt cruiser engine for a replacement of the srt-4 engine? will the 2 motors be the same? if not what is the difference? 2.4 to 2.4 ????
