Well I'm planning to get the Stage 1 kit from Mopar. They say it raises the power to 240HP and the torque to 260 lb-feet. Right now I have a K&N in it, so I'm guessing Im around 220HP atm.
BTW, here is that article from car and driver from the "One Lap of America Challenge". I'll only post the parts about the SRT4.
Just as the SRT-4 is no ordinary Neon, this is no ordinary SRT-4. But it is one you can duplicate through a Mopar dealer near you. Pretty much. The standard SRT-4 is rated at 215 HP and 245 lb feet of torque from its turbocharged 2.4 liter four. The Mopar Stage 1 kit(upgraded chip and bigger injectors, $399) bumps boost from 13.5 psi to as much as 15.5 and output to 240 hp and 260 lb-ft. Eliminating the cat and muffler for track use added an estimated 10 HP. The car rides on stock springs, and the lower spring perch on its American Club Racing struts drops the ride height a half inch in front and an inch at the rear. A quaife limited-slip dif (not yet planned as a Mopar Option) helps put all the power onto the pavement and helps even more on road circuits. We were able to put this One Lap special through its paces on a test track after the event. The results: 0-60 in 5.2 seconds and the quarter mile in 13.6 at 106 MPH, compared with the 5.6 and 14.2 at 102 MPH for the SRT-4 we tested last december. Driven by two time SCCA national champion Erich Heuschele, the SRT-4 stole the Onle Lap Mid-Price Sedan Show, ran third overall in appalling conditions at Road America, and emerged unscathed when Heushele stood it on its door handles (no damage though) at Carolina Motorsports Park. Co-driver, Cory O'Brien helped with highway driving and also offered constructive critisism following the Carolina episode. Both guys are DaimlerChrysler engineers.
And the Racing Bit (skipped to the SRT part)
Aside from the Wisconson-to-Oklahoma trek, other transits were in the 500-600 mile range, mere childs play for the insomniac regulars who populate this event. That category-regulars-included a pretty fair percentage of this years 84 car field. But there were still some interesting Lap Puppies in the mix, including a small flock of Subaru Impreza WRX's, a couple Mitsubishi Lanser Evo's, and a Dodge SRT-4 driven by two time Sports Car Club of America national champ, Erich Heuschele, who just happens to be a DaimlerChrysler engineer. And his teammaate Cory O'Brian is another DC engineer. Any significance to that? Ha. What do you think?
Heuschele's Dodge and various all-wheel-drive Japanese new-age slingshots were contending in the Mid-Orice Sedan class, the second most populous category in this years field, with 18 entries. In addition to battling one another, the Middies (Mid-Price defined as a maximum initial price of $35,000) had to deal with the Ted Lyons-Mike Hurst Thunderbird SC, whose supercharged V-8 reportedly deliver's some 600 hp. Why a 1989 Thunderbird SC- that's C for coupe, as in two doors- is classed with these small sedans is known best to One Lap High Priest Brock Yates Jr. But the bad-ass bird has been the bane of the small-sedan set for three years now, a wolfhound among the Airedales. Still, even wolfhounds can have bad-hair days. As we shall see.
skipping ahead
"Yeah" said Smith. "A time machine." Gerrard was the day's pace setter, putting on a wet-track clinic and passing both Smith and Adee on the track in the process.
But it was Heuschele who stole the show. The SRT-4 had already become a focal point after its performance at Watkins Glen. Even though Heschele had never been to the Glen before, he posted the 11th best time in the morining run, dusting a platoon of astonished SSGT1 (*note from FP: That class has VERY suped up Vette's, Vipers, porche's, a RUF and a Lambo Diablo among other really fast cars) campaigners. Pretty impressive for four-cylinder and front wheel drive.
But the SRT-4's Road America performance went way beyond impressive. Starting first in his group of five, Heuschele not only drove away from his pursuers but went on to lap two of them. In just four laps. On a four-mile track. A wet four-mile track.
His time was the day's third quickest, trailing only Gerrard and Adee, both in much more powerful cars. And with the dreaded T-Bird stuck in a gravel trap--a fate shared by 13 others at Road America--Heyschele's grip on the Mid-Priced sedan lead was all but unassailable.
Perhaps in response to a plea from a member of the Subie/Evo crowd--"Do you think you could slow it down just a little?"--Heuschele provided some comic relief later in the tour, flipping the dodge onto its left-side door handles at Carolina motorsports park, an episode that left Heuschele embarrased, teammate O'Brain irritated, the crowd amused, and the SRT-4 uninjured save for some grass stains. Heuschele went on to claim the Mid-Price sedan trophy, finishing an impressive eighth overall.
