so the 2009 cobalt ls/lt are getting a new gm engine called the LAP, puts out 155hp and 150tq

http://en.wikipedia.org/wiki/GM_Family_II_engine#LAP

 

not exactly new information, its been discussed plenty on here. the LAP will also have VVT

 

Lap/vtec

 

does vvt make a big difference, only reason i care is cuz my balt doenst have it

 

Yup. It's a more advanced engine.

 

like 5hp at the flywheel

 

so vvt isnt that big of a deal

 

lovely, another ecu to crack

 

lolz

 

VVT can also offer a broader torque and hp curve than OHC engine.

Tuning is supposedly much, much more complex.. but shouldn't be that big of a jump from the LE5 or LNF.

Will be direct injection too, correct? I'd expect to see much smaller (1.6L) turbo engines from all American manufacturers in the next couple of years... btw - anybody know who GM has their contract for turbos with? Honeywell/Garrett? May not be a bad investment..

 

Borg warner i think

 

dont confuse vvt with vtec, they are 2 entirly different things. vvt uses a cam phaser and continualy changes the cam timing to help with efficiency. vtec is 2 different cam profiles ground on the same cams, and at a certain rpm the pcm will comand a solonoid and it locks in another set of rockers and changes from the profile that favores low end torque to a profile that will make more power at high rpm.

the 2.2l vvt comes to take the place of the previous 2.2l and 2.4l, as 08 was the last year for the 2.4l vvt.
