Just picked up the Z with Stillen upgraded impeller and 9PSI pulley. Added a temperature sensor just before the Stillen manifold. I'm seeing about a 20-25 degree difference from the IAT MAF sensor to the manifold. I.e. 100 degrees at the MAF sensor and 125 degrees just before it enters the Stillen manifold.

Should have really tapped into the Stillen manifold right before it enters the engine since there is a cooling core within the manifold that should bring the temps back down, just don't know by how much and if its close to the MAF readings. That is the next step.

Mr.Squeeze, what AFR and Octane were you running?

EDIT: Just looked at AIT = 95 degrees and temperature just before entering manifold cooler was at 145 degrees. Ambient temp was about 75 only. Holy crap, can't wait for summer time. ughhh Again, I wonder what temp it is after the manifold cooler.hmmm My mechanic/tuner/z guru is wondering that too.hahahah
