Other elements of the chassis inventory include power rack-and-pinion steering, traction control, and stability control. The latter can't be entirely shut down, although its threshold is high.
But it does add to the challenge of achieving optimal drag-racing holeshots. More on that later. First, let's take a look under the hood, which is distinguished by one real hood scoop and two fake breather vents.
The starting point for the SRT4 engine was the same 2. This one, as you already know, generates a helluva lot more. Here's how. The pistons are cast aluminum, running in iron liners, with forged con rods and trimetal bearings.
SRT was confident the standard production forged-steel crank could take the extra heat and power. Oil squirters help keep the pistons cool, and an external cooler keeps temps of the Mobil 1 synthetic oil uniform. At the top end, there's variable valve timing on both cam banks, with bucket tappets punching the valves, which are made of Inconel a high-temp alloy on the exhaust side.
And, of course, there's that most essential of ingredients—boost, psi max at sea level, but it can rise to 15 psi at high altitudes, provided by a Mitsubishi TD04 turbocharger via a big row Valeo air-to-air intercooler. Like the previous SRT4 engine, this 2. The power peaks are more like lofty plateaus. Max torque is available from to rpm, max horsepower is on tap from to , and the small-scroll turbo spools up quickly.
LOWS: Body roll galore, wallows in hard cornering, disappointing stopping distances. The engine feeds its output into a six-speed Getrag manual gearbox via a dual-mass flywheel. Like the gearbox in the garden-variety Caliber, it's a cable shifter, but the throws are shorter and the engagements are far more decisive. There are cosmetic elements to the SRT package, too, but we think you'd rather hear about the dynamic payoff first.
Let's start with the what'll-she-do department. Getting an effective launch is tricky, something that's true of most front-drive turbo cars. The SRT people predict zero-to mph in a little over six seconds. We clocked 5. The quarter-mile ate up Top speed is officially listed as mph, although one of the SRT development guys says he ran a prototype to as high as Regular readers will recall that the Neon-based SRT4 we tested in April posted better numbers: 5. You'll also recall that a Mazdaspeed 3 [Power Toys," May ] ran to 60 mph in 5.
We should note here that at pounds, the Caliber is pounds heavier than that Neon-based SRT4 and 48 pounds heavier than the Mazdaspeed. Mass is never a plus for acceleration, nor does it help braking. Only the red one was true to the ACR moniker. I had waited two years for white to be available and since I wasn't going to be SCCA racing the creature comforts weren't that big a deal. I almost waited for a commemerative but was afraid the mark up would be ridiculous on it.
I was happy with my car, but unfortunately the family outgrew it. Roll-up windows, no sound deadening, aluminum spare. Bare bones, no wing, no fog lights, roll-up windows, etc. What a wonderful car that would have been. I have a stone white ACR with sunroof, kicker, and side airbags. Is there anyway to tell how many of those there are. I haven't done any upgrades on it yet but the warranty is done now and i am really thinking about it.
Would i be crazy to mod something so rare??? So according to these numbers i have 1 of 23 since i also have sunroof. From a tuned Neon to an horsepower drag racing muscle car. Under the helmsmanship of Dan Knott, a team of diehard enthusiasts at the top of their engineering game started tuning cars for Dodge, Jeep, and Chrysler.
In , the division was officially renamed SRT. Curiously, though, the first car to go under the knife was not a muscle car or even a car with a big engine. And that's where we'll start our list of the most significant SRT cars that helped get the division to where it is today. SRT's first car under its new name gave the import tuning crowd a sharp shock.
It went through heavy development and experimentation, including the use of a supercharger before it finally dropped on the public with a heavily modified turbocharged 2. The chassis was also heavily modified, and the Neon SRT-4 was instantly loved by the automotive media.
From there, it went on to dominate in its class in motorsport. It also took the world land speed record for four-cylinder production cars in , topping out at just over mph. The Dodge Viper is a hellacious car powered by a V10 with a little help from the then Chrysler-owned Lamborghini. It was raw and uncompromising on power and handling, so, obviously, it needed even more hardcore versions. It generated hp and lb-ft of torque in the coupe version, which followed the convertible onto the market.
In , displacement crept up to 8. That included some engineering wizardry from SRT to create variable exhaust-valve timing in a single-cam engine. In , the Viper SRT had hp and lb-ft of torque.
The last generation saw a complete redesign of the Viper by SRT and came in just two versions for The 8. The PVO division resurrected the idea and took it to the wind tunnel. When the Ram SRT got to market for the model year, it used the same 8. The regular cab model rushed to 60 mph in a record-setting 4. The steering and suspension were heavily modified, with Bilstein springs lowering the truck by one inch at the front and 2.
For a number of years, the Ram SRT was a record holder for the fastest production truck in the world. Essentially, it was a Mercedes AMG car dressed like an American, and one of the few high points of the Chrysler-Mercedes union that ended in If you trace the genetic line of the muscle car back far enough, you'll find the Chrysler C had a vital role to play.
The C was renamed the C a few years later. Chrysler brought the designations back for the model year. The C topped the range with a 5.
By the time the SRT version was retired in , it cranked hp from a 6.
