I wonder what percentage of CTS-V owners are members of those forums.

I also wonder what percentage of those members have modified and raced their cars.

I bet the rear differential in that 4300lb+ car with 550lbs of torque will go WAY before the pistons

+1 on that!

BTW, are the pistons in the Sostice GXP forged or hypereutectic? I know those engines have the piston squirters. Maybe that could shed some light as on durability as well.

They're cast. According to GM.

Most people that spend the time on the internet on one of these enthusiast websites is going to wrench on their own cars. Therefore using members of Cadillacforums.com who own CTS-Vs (or CamaroZ28.com who own Camaros) as a guage of the % of owners that work on their own cars is going to be abnormally high, and therefore not an accurate number I'd want to hang my hat on.

I wasn't going to use the % of modders on the forum to extrapolate the total # of modders based on the total # of owners. I was going to use the two %'s together to point out how small the number of modders is in relation to the # of owners.

I figured that. I was quoting you in agreement and to help prove my point.

Why anybody would put hyperutectic pistons in a engine with a blower on it is beyond me. They are going to **** off a LOT of people if the Camaro doesn't get forged pistons.

The hyperutectics are harder than cast, more silicon, but prone to cracking under boost/detenation, cast on the other hand just burns through tho...forged is best for big boost motors...oiling's not a big issue.
Usually starts loosing top ring land pieces at higher boost levels...but if they located the top ring down a bit, it should hold up pretty good.

forged pistons are so cheap, add 400 dollars to the car then lol

I was reading somewhere that the LSA is pretty much maxed out at 550 hp, with it's steel rods and hyperurectic pistons. Crank it up much more than that, and you'll need a shovel and a magnet to pick up the pieces.

The LS9, as you all remember, has titanium rods and forged pistons.

leave it to gm to drop the ball if thats true, the one thing i really liked about those terminator motors ford made was they had beef and could take mods.

TrickStang37

its not just adding $$ to the car for the pistons. also, the rods may as well be upgraded too. and this is assuming thats a forged crank in there. and what material is the block?

but more importantly, the hyper pistons do better in the smog department.

I don't think they dropped the ball - I mean WTF, it's FIVEHUNDREDFIFTYHORSEPOWER!!!!!
