got me an 05 acr

[dio]

Finally got mine.Got myself a brand new white 05 srt4 acr,last one in Canada. Does someome have advice on what mods i sould start with:stage 1 or 2,is a cai worth the $, and how efficient is the stock exhaust is it worth upgrading to a 3" and if so cat back or tubo back.

[The Pope]

buy the big Spearco IC first mod

then buy the complete 3" exhaust with O2 pipe and add 10 PSI more fuel with adjustible regulator, the extra fuel is a must or no real power gain and the engine will run lean and pull timing.

once there buy any stage kit, a stage 2 with toys would be good

[GLHS837]

Pope, I have to disagree. First mod should be exhuast and downpipe. I recomend Maxxfab, although any 3 inch turboback is good. Adding 10 psi is not advisable, since the stock turbo maxes out at 18 or so.

Decide your end goal now, cheap dragstrip monster or very fast daily driver with stock reliability.
Fast and cheap = not reliable
Fast and reliable = not cheap


CAI, not worth it in my opinion, that money would be better spent on a water injection system. No point in cooling off the charge only to have the turbo heat it up. Cool it after the turbo.

My car, doing it over, after three years? Id blow off the Iceman intake, and the Forge BOV, and put that money into a Devilsown progressive W/A injection system.
The Stage kits I would not change. Install, run. That simple. I did all three in sequence, and loved each one in turn. My Stage 3 car still makes me giggle when I drop the hammer.

3" total exhaust nets almost no difference in power out right as the car doesn't have the fuel to run it. Saying " adding 10 PSI is not advisable, since the stock turbo maxes out at 18 or so" means you have no idea at all what I'm even taking about. 1 the stock turbo on one I've modded holds 21 PSI to red line, second I wasn't even talking about boost PSI in the first place. In order to use a 3" true exhaust you need more fuel. 10 PSI more BASE fuel will raise fuel pressure 10 PSI over the whole range. It isn't a 2.2, the computer is going to flip out with 3" exhaust. But an adjustible regulator can be set for this added fuel. BTW how fast is your stage 3 running in the 1/4? Big IC + 3" exhaust with fuel + long Typhoon air intake + 22" slicks = 12.7 @110 MPH. The other one is running 12.71 @ 111 with stock exhaust with stage 1 holding 21 PSI with big wastegate. The high boost really doesn't do much for power, the turbo really isn't doing allot of good at those boost temps. But way over taxing a turbo is why the big IC actually improves the power.

1. Wrong. Way too many folks who have run that as the first mod with no issues. One of my locals did just last week, not one other mod, "freaking out". But your right, I did misread the psi thing, but I still disagree with just adding 10 psi, no mention of tuning the car at all.

2. Who cares, my cars times are not relevant, this isnt a contest, with the faster guy being automatically right. If the question was whos car is faster, maybe, but its not.

3. Thats nice, but again, this isnt a gunfight. The poster didnt ask who could go fastest cheapest, but what his first mods should be. Without knowing him or his goals, it's hard to recommend anything. An exhaust is useful for any path, which is why I recommended it.

4. Bingo, then why do it? To prove a point? At what cost?

5. Again, why? Maybe he doesnt want to "overtax" his turbo.

My point is that you cant recommend a path without knowing goals. Some folks want to just add fuel and boost, regardless of the long term effects on the car. Some folks want it to run for 200K. Some folks want to bolt on a set of slicks and try for a record. Some only want to beat a set time, say 13.5

BTW, I have not run my Stage 3 car at the track yet, and wont til I replace the clutch and axles. And even then, I'll be on streets. The strip is a measurement tool for me.

Congrats on your purchase, If your like me, it's very hard to let it sit in the driveway!

[saw wave analog]

beat the crap out of it! the way it was meant to be driven


my omni has 119k on the block and i flog the piss out of it like it had 20. these cars are meant for having fun!

mwahaha

[GLHS837]

How much on the internals, since you mention the block having those miles?P The blocks fine, it can take way more than it needs to. Way more than the 2.2 could without serious beef. But again, this is not the question.

[saw wave analog]

hehe stock tI bottom end running 18 psi on a tII top conversion, the body and entire bottom end are 119k


a rod could go at any time but.. ill continue taking my chances though haha

[GLHS837]

Easy to do say with the omni, some folks might not be so cavaliar with a brand new 20K car with a warranty. Some might, of course. Which is my point, that we cant really advise the poster til we know more about his budget, skills, tuning equipment and oportunity.

Since the car is brand new and i drive it daily (Except for winter of course)i don't really want to go in heavy mods where the computer could whip out codes like crazy and void the warranty.I was just thinking that having a steady 15 psi of boost would be a great improvement.Right now i get about 12 to13 psi and then it drops down to about 10psi on 91 octane fuel.The big spearco and 3" exhaust sounds good if it doesn't over taxe the turbo.

Spearco makes the intake charge colder. This isn't going to do anything but good for the engine. The IC also makes the car noticably faster, the 3" exhaust didn't make hardly any change in power by itself. But when the fuel was turned up it did, at stock boost levels. As far as over taxing the turbo goes, don't buy stage kits. Clays car here runs a constant 21 PSI with a stage 1. Buy a better wastegate can and run a stock computer, then you'll have 15 and not go crazy with boost. An intake, Spearco and 3" exhaust will make more flow, which makes more power without running high boost. Just run more fuel pressure and a wastegate so you get to keep the boost.

So you wouldn't want the Stage 1 computer as it will void your warranty.
Actually it will depend on your dealership but technically it will void the warranty.
You car, like mine is a daily driver. I will be patient and wait for my warranty to expire before mods.

I agree that the intercooler and exhaust should be upgraded. The SRT-4 turbo is almost spinning at max speed therefore generating a good amount of heat. The upgrade to a 3" exhaust is a great upgrade on ANY turbo car.
Does anyone know if the exhaust has an adverse effect on the warranty?

Oh yea good pick in your car choice. I picked up my '05 White ACR beginning of August and I love it!

intakes dont do anything on our cars! mopar's car makes more power with the stock box then with there own intake....

[GLHS0658]

I've heard of improvements with aftermarket intake manifolds (at much higher HP levels) but not with cold air intakes.

Not that I'd ever get that far in my mods(intake manifold) but I'm thinking about S3, exhaust and intercooler...next year or when warranty is over. I think 300+ HP on pump gas for a daily driver would be just AWESOME.

As GLHS837 said...My Stage 3 car still makes me giggle when I drop the hammer.
