Two questions
Saturday, April 10, 2010 1:24 PM
Ok first question, do we have a throttle positions sensor and Second, do we hypereutectic pistons, reason why am asking about the pistons is from what i read (not on org) is that the hyper piston are better than forge to a certain existent. I guess cause forge can expand and the hyper one are just solid i believe but they have a low tolarance if you you F/A isnt right, but heres the site its a debate about which is better http://www.chevytalk.org/fusionbb/showtopic.php?tid/224135/

you put in in the muffler to the left of the muffler berrings. it measures how much air is going thorough the muffler and can tell how much throttle your giving it.

Uh, I heard from a reliable source that the LN2 pistons are hypers. However, whoever told you they are better than forged is full of . Hypereuctectic alloys are still cast, and therefore are weaker than forged. Forged will be lighter and stronger, in general, but as mentioned, does have a greater coefficient of thermal expansion (meaning you should warm your engine up longer).
