2007 2.2L L-61 With 4T-45E Automatic
Bone stock, factory airbox, factory exhaust, no tune 0-60 9.12 second average over four runs.
GMPP Intake, GMPP Exhaust, Trifecta Tune 0-60 7.73 second average over four runs.
These date from 2011 and were measured using a RaceLogic "Performance Box" timer/G force meter.
According to my notes from back then the air temp was 64 degrees with a 36% relative humidity, winds calm, pavement concrete, tires Mastercraft Avenger Touring LSR V/H Rated, fuel Shell V-Power 97 Octane Premium, mileage on vehicle 63,277.

Another thing that is common in performance tuning these engines is to remove the programmed enrichment delay. Because the throttle is drive-by-wire with no mechanical linkage, the factory gm tune will not give full power for the first couple seconds, rolling onto the gas gradually. This helps with fuel economy and smoother operation, but not helpful on the dragstrip.

Either way - I've been bitten by the performance bug, and already started thinking about replacing the valves,rods,cams, and pistons to get the max out of a ZZP turbo kit. Car is paid off and those upgrades would be cheaper than trading my 1LT in for an SS. Plus having piece of mind knowing my LT has been babied since I bought it with 29K miles over another car where no one knows but the previous owner.

IMHO-The slight horsepower advantage of the LE8 2.2 over the L-61 2.2 is pretty much nullified by the horsepower and torque peaks of the LE8 being moved higher up in the power band.
When accelerating from a standing start, an engine that hits its peak hp and torque earlier, should have a very slight edge and the LE8 gives up a little torque to the L-61.
Lets look at the numbers in stock form.
L-61....
149 hp (111 kW) @ 5600 rpm
152 lb·ft (206 N·m) @ 4000 rpm
LE8....
155 hp (116 kW) @ 6100 rpm (gasoline)
150 lb·ft (203 N·m) @ 4800 rpm (gasoline)
The LE8 engines do gain 6hp and 8ft lbs or torque on E-85, but there are parts of the country like central Carolina where E-85 isn't widely available. So it's not a factor here unless you're Flex-Fuel capable, and willing to hunt down a station selling "corn squeezins".

Nvm on the e85 in the 2.2LAP's. Spoke with zoomer at zzp since I'm getting ready to order their longtube and dp combo. I asked him if 85 would affect the dp cat and he said there's no reason to run 85 on a 2.2. He did not elelaborate as to why.

So today I was on the same strip of road with my 2010 auto SS, and decided to see what the 0-60 would be.
In D gear and had competitive mode on, without launching the car it did it in 7.82 . Boost maxed out around 10.2 PSI.
Interesting to see my LT ran it faster with the GMPP intake, exhaust and trifecta tune. My auto SS is bone stock, but this definitely makes the urge to get the GMTU, new intake, exhaust, and trifecta tune sooner than I was planning.
I still have the LT (and it's still insured until the 15th), so I might have to do this test again to make sure that initial run in this post was accurate. I find it hard to believe it beat the auto SS to 60 MPH.

Well that's certainly interesting. I'm hoping to learn more about the 2.2, I know the 2.0L inside and out and finally understand VVT now that I've completely broken it down. I'm purchasing the mechanics special HHR listed here yesterday. Need a winter car while Harley(08SS) and the Joker(08LT) go under the knife. I'm going to tear out the motor as soon as it gets here, rebuild the bottom end, and try to stuff a turbo in there! I'm going to get creative and make the intake and charge piping myself.
I've read you cant use HP on the earlier HHRs, hopefully I can with the 08.

Thanks for the info. This sounds like a great system. My engine builder uses a local wizard with a laptop that will set all the perimeters for the engine and trans. He also has to calibrate the HHR speedo to the 4l60e trans/tire diameter.
