Cobalt SS/TC Vs LS2 C6 Vette
Just a friendly run to see how my Cobalt would stack up against a bone-stock 6-speed Vette at high altitude. In the dig race I get out on him by about 3 cars before I shut down around 110mph. In the roll race I get about 4 or 5 cars on him and shut down at around 115mph. Hopefully going to run again if the Vette does some mods.

- ZZP 3" Catless Downpipe
- ZZP Bolt-In FMIC
- Hahn CAI
- ZZP Rotated Trans Mounts
- Driver mod (except shifting 1st to 2nd, no NLS -- too scared to break tranny)
Street tires, stock everything else.

these tc's are starting to grow on me, I'm thinking of picking one up as the new daily driver in a few months, put my cobalt back to the turbo'd fire breathing monster it once was.

And NLS 1-2 was easy when I was GMS1. It got hard when I got tuned because it's hard to time it with the tires spinning. I've done it once and it works, but I'm not testing my luck.

DA at the track this Friday evening should hopefully cooperate and drop below the 8000ft mark as it cools down. Crossing my fingers.

100% bone stock fuel system. The LNF uses GMs SIDI Direct Injection fuel system which uses a lift pump in the tank and a mechanical high pressure fuel pump and injectors much like a diesel. The stock fuel system supports about 400whp on E85 and a little over 450whp on pump gas before you have to either stroke the pump with a larger fuel pump lobe on the camshaft or add a 5th injector setup. So unless I goto a larger turbo, I won't have any fuel system woes.

It's terrible... about 18mpg city and 22mpg highway. Used to be ~23mpg city and a little over 30mpg highway on 93 octane. The power increase is worth it though. That and premium is about $3.70/gal here right now, so it costs roughly the same per mile to run E85.
