I bought a 8$ temp gauge from Ebay and installed it by my throttle body so I can see my discharge temps. I bypassed my IC for a few more #'s a while back sinse its cold out and I wanted to see what my temps are. I took it around the block and at 44deg out side my cruze temps are in the 60's and at WOT the thing goes way up. not sure how high it goes because I dont think I ever went past 3 #'s.
My intake air temp sensor is relocated in the intake manifold with the lightning set up so I can monitor my intake temps with my sct..
Generally about 30 deg above ambient but it will climb at closed throttle. The air being recirculated with no place to go tends to heat it up..
