2005 GTO -- Supercharged With 525+ Rwhp
Well, I think it's time to move on to a new chapter in my life. This GTO has been, by far, my favorite vehicle I have owned. It is very comfortable, and has tons of power all through the RPM range.
The car needs absolutely nothing, except for a complete detail that will be done in the next few weeks.
Modification list (I am probably forgetting some things):
Engine/Performance:
MagnaCharger 122 with upgraded 1:1 rear pullies
3.0" front pulley (nets around 9-10psi)
Pinned crank pulley
63lb Siemens injectors
LPE fuel pump
AIS dual nozzle methanol kit
Hardcore 4" Cold Air Intake
Kooks 1 7/8" stainless headers with JetHot coating
Kooks mid pipes with catalytic converters
Stolen Fox H-pipe
180 degree thermostat
Two axle-back exhaust systems - one with Flowmaster Super 40 mufflers, the other with Dynomax bullets
Two professional tunes for the car: 2-bar Speed Density and MAF
Two Mickey Thompson drag radials (275/40/17) mounted on stock 17" wheels
Hawk HPS brake pads
HPTuners Tuning Software and Cable
Transmission:
Bird of prey clutch
Stainless steel/braided lines
Remote bleeder
New slave cylinder
B&M shifter
Exterior:
Kirscher front splitter
19" TSW Thruxtons
B&G lowering springs
2006 GTO tail lights
Koni yellow adjustable shocks
Pedders tie rod ends
Pedders bump stops
Pedders strut mounts
Arrowhead Performance rear decklid spoiler
Racemesh grilles lower stainless grille
Interior:
Harlan shift light hidden in vent
Dual gauge pod
Autometer electric fuel pressure gauge
Boost gauge
This car recently put down 527RWHP/515RWTQ on 9.5psi and some methanol. It is a blast on the street. Unfortunately, I do not have any good timeslips for the car, as it has only been to the track one time since the blower install, and it was 90 degrees. The car was not on a great tune, and it had no methanol on it. On that day, it ran a 12.0 @ 117. I have no doubt that this is a mid-120s car with the tune where it is now and cooler weather...do the math with the numbers it put down.
The car currently has 45k miles on it, and is driven easy on the street...with the occasional spirited run just to hear the supercharger scream. Oil is changed every 3k miles with Mobile One since I have owned it. It gets a lot of attention on the street...more than any car I have owned.
I know I am forgetting some things--feel free to ask any questions.
$23k for the car as it sits, with every modification listed.
