05 mods

I am thinking seriously about buying an 05 when available. What mods have you guys found to work well on the 04's. Thanks.

The 05 Has Higher Compression Ratio So Supercharging Wont Be The Way To Go. 05--- 10.9 To 1 Cr WOW... allmost 11 to 1 ..... i bet the knock sencers will get a work out!

Hoping to find a CAI, Tune and Exhaust combination for another 25-30 horse.

Main mod to do will be a lower rear end gear ratio. A different cam would also be a good mod. The engine already has a good set of heads on it so that eliminates those. As for power adders, nitro is going to be the best bet for the compression these engines have.

no2

I,ve seen numerous LS1 T/A's and Camaros at the track that respond really well with the nitrous that sprays into the air duct. 4.10's would be a good choice?
