2004 257 sxe...Quest for 10s on stock long block

So long story short...when I was watching undersrtarmour get into the 10s I also met an guy in the Army who had a red srt4 with a Delta 42 and a shot of nitrous in Louisiana back in 2013 at a local track. Fast forward to 2014 and my dad purchases this same car for $6500. Srt4 at this point has a Precision 5557 turbo with .63 hotside on the traditional agp log manifold. Car's modifications at that time were mopar STS, BC coil overs, AGP race FMIC, Sieman 888/1025cc inj, full blown dual pumper with two 190s, Side exit 3" exhaust, AGP 38mm wg, aeromotive FPR with -8 feed and -6 return,JMB 4" CAI, SDK ported TB, HKS BOV with cold and hotside pipe, small battery, N2MB wot box, 2-step, and boost box. Car is still stock long block, stock trans, and stock clutch with a rescale tune around 19psi (not safe level at this point). Car was very clean for how many miles it had (around 105k) with all panel matching, which isn't too common for the red srt4s. Perfect interior with everything working. Few times when my dad drove up from Louisiana to N.C. we would go to the track and see what she'd do. Most runs with borrowed Koesi K1s on 24.5x8x15 MTs were in the high 12s. After getting a email tune from Nigel we went to An event at Farmington's 1/8 mile track in September 2015 and were able to get into the low 8s and high 80s in the 1/8 mile. Went a few rounds in the 8.0 index class, but didn't win. At this point the only problem with the car is anything under a half a tank it would cavitate under boost, and around 1/4 tank the car would start to lean out and stutter around turns. I knew it was probably the full blown dual pump hangers doing it. In the winter time driving back to LA with the twin pumpers still in I was about to get 365+ miles on a tank being around 31+ MPG!!. Not to shabby!! Early in 2016 at a local 1/4 mile track we were able to dip into low 12s. Getting confrontable with the launches and lower tire pressures. But unfortunately the stock clutch met its demise....so I decided to go to a full face modular clutch that was still VERY streetable so I chose a South Bend stage 2+ endurance about a month later. [url=https://imgur.com/SmFrR4j][/url During the clutch install a buddy went with an upgraded intake manifold, so he gave me his P&Pd one and spray a lil red on the valve cover. So I keep getting the car faster and more reliable to send back to my dad in Louisiana so he can tear up the streets lol.


Later in 2016 during an oil change he had an issue with the car not starting, long story short, it ended being a relay along the pinch weld for the full blown twin pumpers. My dad isn't too mechanically inclined and gets frustrated with the small issues so he told me just to take it....he'll continue to pay for the insurance and I just send him $300 a month til I pay the $6500. Seemed fair to me, so back to N.C. she went. Come early 2017 I traded the wheels that were on it for some RFP1s with Continental Extreme Contact DWSs 255/40/17 for $500!!!! In February I went to Galot Dragway's 1/8 mile track and got some pretty consistent low 8, high 7 sec passes. In march with the fuel issues and sometimes having to jump the car with the bad battery I chose to ditch em. Instead went with a filter on the turbo, single walbro 255 and big battery. Then since I NEVER used the nitrous, it was time to remove it!!!! While the car was down I figured id get a few things powder coated. Finished everything up around midnight then its off to Import Face Off!!!

First pass off the trailer at Rockingham!
AFRs were still a little flat because I also installed the kinnect fuel pump rewire which greatly helped my high rpm fuel pressure. End the day with another 11 sec pass and drive it an hour back home.










At a local car meet up (sonic lol)



Couple shots while I was at NCOA in TN





In July 2017 I won the 12.0 index at Fayetteville Dragway!!!

A week later I drive it from NC to PA for Carlisle!!

Made it home!!!


In August I drove it to Charlotte for the SCT event for the 12.0 index class. Made it to the semi finals

Back to Rockingham for some IFO action!!





In October made it out to Farmington's 1/8 track for the 8.0 index..i was a lil fast

Before the end of 2017 was up, I made a trip down to Brutal Speed and Tuning and got dyno tuned by Nigel


Final numbers were [email protected] on pump. [email protected] on c16.


Start off 2018 with new dual exhaust and a shot from the track!!




Fast forward to the IFO event at Rockingham in April 2018



Personal best, 11.5 index winner and drove er back the hour drive home!!
Later in the month I drove back out to Farmington to get another solid run, but the Southbend Stage 2+ didn't like when I tried race gas for the first time..


Time for spec 3+??...




New LED tail lights I got in May

Clutch finally came in!!

Lets see how this Borg Warner 257 SXE w/.82 hotside will do...

But first, lets try the new slicks with a good clutch!! Took me about a month to get some time to do it.





Fast forward to November and i'd try one more time out to see how she does. And would ya know the orginial owner of the car from Louisiana is now stationed in NC and was there. Only to get his butt beat by his old car in his mid 11 sec chevy ss lol


Personal Best!!!

1st attempt on race gas with SPEC clutch and new slicks...something happened in 4th, spin or slip, so I let off and got back in it.

Yeap, clutch is toast, 1250 miles and maybe 6 track passes. Slipped bad in every gear. Still drove it that hour back home.



Lets go 2019!! Got a used ACT 4 puck clutch and finally through on my 257 SXE




On her way back for a retune


Made more power with this turbo on pump than the 5557 did on race gas

VERY NEXT DAY!!!
#1 Qualifier of the trailer!!



Still shifting early, not using the extra 500 rpms the new turbo wants

made it all the way to the finals to have this happen....fixed and drove it back home.

Finally got around to changing the busted 4th mount. Pretty much too out every motor mount, and the two bolts from the p/s pump.
