Okay, maybe you guys can give me a little insight here;
My buddy has an 05 SRT-4, it has the following mods;
FULL TBE catless 3"
Short Ram Intake K&N brand I believe
Diablo Tune
Stage 3 Clutch which he just installed beginning of May
Hurst short throw shifter
BOV
My mods are in my sig.
His tires have seen better days but they aren't completely dead yet. We did a pull from a roll at about 30kph (20mph) and I was dead even with him the entire way, we both were scratching our heads. He thought he may have a boost leak somewhere, and I thought he was gonna pull on me decently.... Didn't happen. We are gonna go again and I'll record it next time, but I kid you not he was dead even beside me the entire time and we went up to 180kph (110mph)..
Ambient temp was prob around 70 degrees and he knows how to drive, hes had numerous high powered cars before, all of which were stronger then the SRT and he auto crosses regularly... so it wasn't a shifting issue, he made every shift smoothly...
