I have done a fair amount of research on how to increase HP significantly and decided to go with a supercharger.
Here is what I will sign off on Sat unless I hear a better solution from the crowd. Appreciate as much feedback as possible. Love the 2005 GTO and I don't want to screw it up.
- ATI Procharger Tuner Kit
- Unichip Q series Piggy Back Module
- Unichip turbo module
- 42 lb Bosch injectors
- 160 degree thermostat
- Spec Stage 3 Clutch.

I would appreciate feedback especially on the clutch since there are so mancy to choose from. I want drivability but I need something that is going to handle the additional wear and tear. This is rated up to 600 hp at the wheel. Am I better off with the stage 2 (better driveability but rated at 475 rhp). i know everyone is going to ask so the entire package including tuning, dyno etc is around $9,500.

I there anything I'm missing? Bottlenecks that I'm not addressing?
Phase 2 will be some sort of catback or y pipes, suspension??

tires! you didnt account for tires. And the rearend will need some beefing up. Add another 3k to your price and you will be set.

$9500 for that seems high to me, but I could be wrong. You have to take all things into account, the stock rear will not last forever with that power, and then if you get sticky tires your really gonna shorten its life. I don't see fuel pump in there anywhere either? If it were me and I was gonna boost my gto, I would seriously consider a different set of heads and thicker head gaskets to lower the compression ratio, its not very boost friendly at 10.9:1

I believe the tuner kit comes with an additional fuel pump.

$9500 is entirely too much, send me a pm of your goal and we'll go from their.

big_mike

wait, is that an installed price?

GTODEALER

Still a little on the high side.

big_mike

depends on what his shop charges for a clutch upgrade, blower install, and rags. those rags are expensive at some shops! lol

Mike Kortney

I don't have my price list in front of me so I'll estimate
Pro-charger is around $4,800
Installation is $1,400

42 lb bosch injectors: $500
Install; can remember lets say around $300

Clutch: $650
Install: $300

Unichip piggy back: $500
Install: $250

Tuning and dyno testing: $500
+ tax
I know I'm missing a couple things + I estimating but this a very rough idea
Adds up quick. Definitely tires are next.
I think I have the stock tires 245 45 17,
What would be the best tire and size for takeoffs but also does ok on streets.
How about BFG Drag Radials>

big_mike

drag radials in a 275-40-17 will work wonders on your car!
