Hello all! I'm Sherman and I'm new here and have read lots of interesting comments regarding the newest member of the Turbo-MOPAR family, the Caliber SRT4. I thought that I would give you a little bit of performance information and then I will gladly answer any questions that anyone has on the car to the best of my abilitiy.

2008 Caliber SRT4 (CSRT)
285HP 265TQ Stock
13.98 fastest stock 1/4 mile time-most are running low 14's
12.72 fastest modified CSRT- link to info on this car:
http://www.caliberforums.com/forums/showthread.php?t=5348

The 2008's come in four colors- black, red, silver, and orange. Production on the 2008's will stop in the next month with projected numbers of 1000-3000 being produced. They are a very low production, very fast and powerful turbo Mopar; by my calculations, the most powerful turbo 4 cylider vehicle Dodge has ever offered. I would hope that you would welcome this car to your ranks as the current flagship it is to the Turbo-MOPAR platform.

About me- My first memory is of standing in the backseat of my Gramps' 69 Superbee and yelling, "Go 100 grampa!". I've been driving MOPAR's since I've been driving. Here's a few that I've owned- 2008 Caliber SRT-4, 2003 SRT-4, 96 Neon ACR, 87 Shelby Z T2, 86 Shelby Charger, 85 Omni GLH-T, 71 Roadrunner, 74 Roadrunner, 72 Charger, 73 Duster V8.

Any questions?

Is yours modded in any way? What are the various mods that can be done and what trouble spots have you noticed thus far? How many miles are on yours already? Have you actually taken yours to the strip and seen what it would do?

Mike, if you go to the link in his original post the fastest CSRT has dyno numbers:

Neon SRT-4
11.431 @ 123.61__________417 Hp / 450 Tq


Caliber SRT-4
12.782 @ 111.09__________407 Hp / 460 Tq

similar HP/Tq numbers and the CSRT4 is 1.3 seconds slower, so I bet it does feel a bit different.

Mike,
I had the NSRT for several years, so driving it was like a comfortable pair of shoes. So far it does feel quicker and more agile than the CSRT, but I've only been driving the CSRT for a couple of months. The CSRT, on the other hand is much faster and more powerful! It is an SRT so all of the suspension has been tuned to take care of the size and weight of the car. I haven't road raced mine yet, but the reviews form the owners that have and the feedback from the SRT Driving Experience schools that have taken place has been exceptional. The more you throw at the car the more it can handle.

No, mine is stock and will stay that way- just as my NSRT did. Mine is a daily driver and I need the warranty until the payments are done. I have 4000 miles on it so far. My NSRT had 126,000 when I traded it in and it never saw the inside of a dealership. It was the most dependable vehichle I have ever owned. The type of mods for the CSRT available are already endless, I'm sure they will be similar to what was/is available with the NSRT. There are several vendors dealing specifically with these cars. For more info you can check out the vendor sections on www.caliberforums.com. No, the tracks are just opening up here so I haven't made it too any of the open events yet, but will soon. :)

The ESP doesn't really feel at all. The only time it kicks in is if you let the car get squirelly on you. Its basically to keep inexpierenced FWD drivers from ending up in the ditch etc. It is supposed to help eliminate torque steer, but that really isn't an issue on this car if you compare it to earlier FWD performance cars. There is a button on the console to turn it off for racing or whatever. There is also aftermarket devices to completely turn it off. My expierence with it so far, is that it hasn't been an issue- good or bad. It might be helpful in the snow and ice. I guess I'll find out next winter. When I race I just turn it off, just like the AC.

The Red Shed, as the CSRT is called, is ever increasing in power and will surpass the NSRT very soon. There are several other heavily modded CSRT's in the works that may surpass the Red Sled too. Its a bit of a competion among the various shops to see who has the fastest more poweful car. I guess they think it will help sell their products.

Update on CSRT track times: A "regular guy", Matty, ran two 13.4's with his CSRT this weekend. He has done nothing to the stock internals or turbo. He has a TBE, slightly larger injectors, a boost controller and timing module. The power of these cars hasn't even started to be unleashed! He's hoping to run 12's tomorrow night!

Yes, there will be a 2009 model. There are a few changes, nothing performance wise. Orange is gone, blue is available. MyGig will be standard. If you are interested let me know and I can post some links for the 2009. No price numbers yet. Orders for the 2009's will start in the next few weeks and they start building 2009's in July.

Modern Performance is a great shop! They have came up with lots of good parts for the CSRT already. I haven't had any problems with my mounts, or anything else for that matter, but I'm not planning on running 10's. :) Even the guys that are running 12's already are doing it on the stock mounts, but stronger parts are always welcome. :thumb: Thanks for the interest and the note!

What kind of gas mileage are you getting? It sounds like you don't baby it too much, so your numbers might be what us "average" turbo drivers would get. I would hope it is better than the Caliber with the CVT. They are dogs to drive. It sounds kinda like a snow mobile. I haven't seen better than 27 mpg driving a company owned one. And that's mostly interstate driving.

Personally I'm averaging right at 27mph, with that being 40% highway and 60% city. I've gotten 32mpg on the highway. It is funny that the guys getting the best MPG are the ones that have done the most performance upgrades. One of the cars in the 12's is getting 36 mpg on the highway and there are several guys getting 34 mpg or better. Yes, it does better than the CVT cars. From what I have read and experienced, I would say that the advertised milage is very close to what you can expect.

The increased milage on the 12 second car can likely be attributed to the upgraded turbocharger. Less backpressure and a higher boost threshold will do that. It's one of the rationales I'm using to justify the upgrade the turbo on my Neon SRT-4.

I finally got my SST replaced, the first one took a crap.
Also installed a ported manifold.
PTP told me since I didn't have a ported mani, the extra heat from the bigger turbo cooked the seals.
I'll let you know if I experience any increase in MPG.
I noticed the exhaust is a little louder.
I'll have it up @ SDAC 18 as well.

PTP is PT Performance, a vendor.

SST is their SuperStock Turbo... basically a stock turbo with an upgraded compressor wheel and a clipped turbine.

TBE is a Turbo-back exhaust.

I just had a chance to get in one last week. I was suprised at how roomy it was and I like where they put the boost gauge too. The reason its in the shop is because the carrier truck driver backed in into a curb which scraped up the back bumper and bent the exhaust.

I gotta disagree with that. I had a upgraded turbo on my car, larger compressor wheel in the stock (machined) housing and the manifold was stock and unported. Had it on for more than 45,000 miles and NEVER had an issue. I also didn't have a turbo timer or anything special for cooling.

They are about 1/2 the size of a parking space and I have only seen them in very bright colors so far. At least, I assume that is what these cars in the back lot with Chineese graphics at work are. what an ugly POS. I would rather see them blow the dust off some old tooling and bring back one of our old body styles. I sure would hate to get T-Boned by a Surburban in one. Of course, maybe it bounces like a ball. I swear they look just like an Easter Egg with tiny 12" lawn mower tires.

I finally found some time to get the CSRT4 on the dyno. It was 97 degrees in the shop but the car still managed 280 WHP and 290 ftlbs. Not bad for 10psi of boost. Various air cleaner configurations made no signiifcant change in power including no air cleaner at all. I did attempt to by-pass computer controlled boost and made 300HP at 12psi but the curve was all over the place. Boost would spike to 12, drop to 8 and then build back to about 11 at 6K RPM. Had plenty of fuel though. Perhaps a stiffer spring in the wastegate but I can't be sure what the throttle by wire system is doing.

That is a totally stock pass. I've got some work to do to figure out how to take control of this thing. I can tell you it didn't feel like 280HP. It was really smooth and after driving it around a little I didn't expect to even hit 250.

My opinion is that they are underrated for insurance purposes, as they were originally advertised at 300HP and then it was backed down to 285HP, but most are dynoing much higher at the wheels.

Comments on how a car looks from an Omni owner never cease to amaze me! I can say that because I used to be one! :) But seriously, I just can't imagine that everyone doesn't find the CSRT completely bad --- and beautiful! I get stopped at least once a day by someone asking questions about the car and saying how great it looks. I never got that from my GLH-T.

I can say that because I used to be one! :) But seriously, I just can't imagine that everyone doesn't find the CSRT completely bad --- and beautiful! I get stopped at least once a day by someone asking questions about the car and saying how great it looks. I never got that from my GLH-T.

I feel part of the charm of the 4 door lbodies is their ugliness. Maybe someday i will feel the same about the caliber.

How much boost does your caliber come with stock?
It is boost restricted in first and second. The max I am seeing is about 12psi, but that is just spikes. I would guess it averages between 8-10psi. The cars are very "detuned" from the factory. As the aftermarket tuners are showing, once you get past the factory restrictions the car is a monster!

It is in the fact that most people couldn't launch the car with 300HP in 1st and 2nd and even with the boost restriction, keeping the wheels from spinning is tough. But the ESP traction control only comes on when you get sideways or start to make the car think you are loosing control. Truthfully, it has not bothered me at all.

I finally found some time to get the CSRT4 on the dyno. It was 97 degrees in the shop but the car still managed 280 WHP and 290 ftlbs. Not bad for 10psi of boost. Various air cleaner configurations made no signiifcant change in power including no air cleaner at all. I did attempt to by-pass computer controlled boost and made 300HP at 12psi but the curve was all over the place. Boost would spike to 12, drop to 8 and then build back to about 11 at 6K RPM. Had plenty of fuel though. Perhaps a stiffer spring in the wastegate but I can't be sure what the throttle by wire system is doing.

When I got it, it would only make 7. After the PCM reflash, it made 10. SO that run was with 10 psi of boost.

How was theirs modified? I assume they were road racing it? One of the guys on the caliber forums posted photos from some of the road racing he has been doing, including a second place finish in a open car competition. The CSRT's are designed to be fast in a straight line AND around the twisties.

"Some other tuning" is an understatement. I think the most amazing thing about that rig was they were able to keep it 'stock appearing'. When you have access to all the factory toys, anything is possible:eyebrows:. While Mike Stimac was tossing me around in the passenger seat of his Masi Daytona, I thought we were gonna get around the CSRT in a hurry, Mike had to actually work at it:clap:

I hope they take it to the Gingerman Raceway Shelby event in July that Robert Lane from Team Shelby told us about. I think there will be some suprised TS members at that track:evil:

I haven't raced mine yet, but the reviews coming back from the guys driving them at the SRT Track expierence has been very positive. I have been saying for awhile, to just wait until you get to see these cars in action before you pass judgement. The more they race- both drag and Xcross- the more you will see what they are capable of.

So you guys don't know what actual upgrades were done? The stock brakes are the 13" highway patrol setup off of the Charger. I'm guessing the reason that the car looked stock, is that it probably was. There really isn't much you could do that hasn't already been done by the SRT team from the factory. As I stated above, one "regular guy" is racing his stock CSRT and beating Corvettes, Porches, WRX's, etc in autocross events. He says the more you throw at the car, the better it handles.

As stated above, this was an SRT engineering mule. The car was equipped with parts that may or may not make it into the Mopar Performance catalog. Visible differences from stock were lightweight wheels and race tires, upgraded brakes. I do not know what was done to it powetrain wise, but I could pull away from it eaisily in the straights. It was however able to outbrake and outcorner me. I was on all-seasons. Never do that again!

A friend of mine races his stock Subaru Legacy non-turbo and is able to beat Porsches, Vettes, and WRX's. Autocross is more about driver skill than setup, untill you get really really into it. Tell the "regular guy" he is not giving himself enough credit.

That is a totally stock pass. I've got some work to do to figure out how to take control of this thing. I can tell you it didn't feel like 280HP. It was really smooth and after driving it around a little I didn't expect to even hit 250. I was a Caliber SRT/4 fan before SDAC18 and really am now after riding with Erich Heushele around Waterford Hills for 3-4 laps.

He is the lead developer/engineer for the car and some things he told me during those laps. Very nearly all of them, will put out close to 300hp (crank). They wanted to advertise them as a 300 hp new car, but the car doesn't feel like a 300hp car when compared to other cars with that rating. The reason is the torque management (according to Erich). In 1st & 2nd gears, t-m is in force and limits torque so the wheel spin is kept to a minimum. But once it hits 3rd, then it plants you in the seat with it's full power.

Since it was apparent he was on the verge of losing traction at every corner all the way around the track (tires growling but not quite breaking loose completely), I asked about the electronic limited slip vs. a quaife. He said he fought for the quaife to be in the car, but then found it just didn't work right in it. He said the quaife just wasn't what he felt the car needed, and they could not get it balanced at all (inside tires kept unloading). He said with the bigger brakes needed for the VLI to work, the car is a much more balanced package, AND the VLI does work as it should. I thought that much was obvious during my ride.

One other observation to make here. The long standing record of hp per cubic inch belonging to the T-III motors is history (the car sold with the highest hp per c.i.). I don't know what the c.i. is for a 2.4, but if using the liters instead of inches, the T-III made 101.8 hp per liter while the SRT/4 Caliber makes 118.75 hp per liter.

However on another forum he posts on, I beleive it is him stating that he has Realtunes stage one kit on the car.

The cars are boost restricted from the factory, so it varies between cars. I would say the average max, stock, is 8-12psi, and those are just spikes. That is one of the biggest stock/factory bottlenecks to really opening these cars up.

Ha, my buddy last night was trying to tell me something came from the factory intercooled but not turboed, but turbo was optional.

I know that's an option on all the 08' Yugos.

Uhhhh....yeah. They just released their first debut in '07. It's an import. Where have you been? :confused:

No, I'm not serious. I guess I must be at least a year or two older than you. If it weren't for the movie dragnet and a yahoo collecting the convertibles in my area while always advertising them for sale at ridiculous prices I would have no idea either.

I haven't read that this actually happened. Do you have a link?

Don't know if this is still active but here goes. I drove a new CSRT a couple of weeks ago and the power delivery was very uneven. If I barely hit the gas it jumped and when I took my foot off the gas it almost seemed like I downshifted. Then later in the test drive I tried to accelerate and it almost seemed to bog down, I'm not talking about tubo lag but a lack of response. Does any of this seem normal or was the one I test drove having problems. The salesman told me it was normal but I find that hard to believe.

I think there was probably an issue with the one you rode in. Was it sitting on the dealership lot? Perhaps some Dbag put regular gas in it?

That was my first thought too.

First, if possible, I would test drive another car to see if it feels different. The CSRT's do take a bit to get used to, both with shifting and with throttle response. Two things that may be causing the issue you described would be the spark plugs having crazy gapping, which has been an isuue with may of the cars from the factory. The other would be the boost restriction in the first two gears from the factory. If you don't keep the RPM's up in 1st and 2nd, the car will bogg. The Stage 1 kit is supposed to take care of that and should be announced very soon. :)

Good luck in your car search! Let us know if you have any more question.
