very nice, glad to see this thread. My wife really likes the cruze, and we are really close to making the call to trade in the 09 LAP sedan for one. shhh don't tell her but if all goes well Vince will be getting a call from me for a tune, just don't tell the wife. hahahaha

Only Cruze I'm interested in is the Z-Spec or the unreleased Cruze SS (if it's gonna exist)
Vince, I know you can't answer this quite yet, but what do you expect you can do? I don't imagine it getting to 200hp safely

OK, couldn't resist. I put it on the dyno today (but haven't done any tuning yet - still working on some bits and bytes there). I'll scan the dyno sheet and post it later, along with pictures of the car.
Stock, it put down between 117.5 and 121.2 HP and 128.1 and 134.3 TQ. Max torque was at 3600 RPM, and max HP was at 5200 RPM.
Torque curve was pretty flat. I dont know what the deal with the fueling is, though, the higher run it was at 13:1 until 4400RPM, then it gradually dumped to 10.3:1. The worst run it went to 10.3:1 at 4400 RPM. I believe this is catalyst protection kicking in.
200HP might be a stretch, but 150HP (170-180HP at the crank) at the wheels should be very doable, properly tuned, with the boost turned up, and on supreme unleaded. These cars have an ECU-controlled thermostat and it commands this car to run at 220*F all day long which is NOT good for power. Yes, this means we can "tune in" a low temperature thermostat!

I think it is only a matter of time before we see a factory-souped-up Cruze. GM has to pretend to be responsible and focus on their bankruptcy turnaround since they are IPOing this week.
It may also depend on how well the Cruze catches on in the US (although admittedly they did have a Cobalt SS from day one)

Man, this thing looks like it's half the size of the LNF. LOL. Not even close. GM also reversed the intake and exhaust ports (turbo is on the front of the engine now). It has a plastic "log style" intake manifold and the boost tubing can't be more than 1.5" or MAYBE 2" in diameter.

I believe the running temperature of the Cruze is being referred to. On the Cruze, the ECU controls the thermostat, and the factory programmed it to run at 220*F all the time, presumably for economy.
That's horrible for performance, though!
