i read somewhere that the 2007 Le5 had around 150WHP while the 2008 had close to 159WHP. just curious if anyone has the answer thanks

I'd suggest that's not true.

difference is 2 brake HP

171 at the crank for 06 / 07, 173 for 08....at least that's what GM claims.

I expect you could take 10 brand new identical Cobalts (any trim as long as all the same), run them on the dyno, and get a 3-4 hp range in outputs just based on the variations (small as they are) from one car to the next.

171 was in 06 only

07 and up are 173



nobody dynos at the same numbers... a click of a strap makes you gain WHP

brickerenator

heh

you're right

weird

I distinctly remember Chevy claiming a 2bhp gain over 07

I stand corrected on the years.

Was more talking brake horsepower than whp though, I am very well aware of how much effect lashing the car (or bike in my case) down tighter has on the numbers produced

Point I was trying to make was that no 2 engines (or transmissions) are exactly identical from the factory - at least not in a < $25k econo box, might be a different story on a > $1m exotic.

Should play with tire pressure on a dyno some day, can make for some "interesting" results
