A bolted up LY7 beating an R/T Charger? Sure, if the R/T driver forget to turn his car on before the flag dropped. They'll run high 13's with a good driver, trapping 100+. The CTS will run high 14's trapping 95ish. The only bolt ons available are CAI/Exhaustwork (combined for 20hp at best with stock cats) and the iceolator and a tune. The CTS needs alot more then some very minor bolt ons to run a 13. The ATS with 3.6L 323 hp, and less weight, runs a high 13. You wont pick up 70 hp from a CAI/Tune/and icolator. 40 hp if your lucky.

Something is wrong with his car, or he cant launch the car. They are smoking fast, comparatively.

The trans can be swapped with a 5L50E. Same case, stronger internals. The diff is a minor problem. Run a diff from an 06 or 07 CTS-V...they are more reliable. AFAIK, they are basically the same as the LSD in the V6.

A better power delivery %? Bolt the shit out of an LY7? YOLO? What kinda hipstar talk is this crap?
Seriously tho...what do you mean by a better power delivery %?
----------
PErformance parts? If youre going to mention them with claims that you beat a 300C with the 5.7, then tell us what the parts are...or it comes across as BS.

A catchcan is not a performance mod. It can help restore hp, but it cant create power that was never there to begin with.
Where are these 6 grand heads?
If you want to beat him, challenge him to an 8th mile, you may have a shot there if you catch him sleeping. Better yet, challenge him to an autocross event.
