lol this 3.0 vs 3.2 is just as silly as my thread
anyways...some developments and testing results tht I'd like you to peruse and make comments as to whether theres a problem...
so, was quiet at work today so plummed in the vacuum gauge straight from the brake servo (and tee'd it in so it was all still plumbed up)....... got car up to temp and at idle it was holding a ROCK STEADY vacuum of 20inHG. Perfect!!!
I then brought the rpm's up to 3k and held it there.....again, rock steady vacuum of 23inHG. PERFECT! This confirms there's zero exhaust restrictions, zero vacuum leaks and the engine is very healthy. really really pleased actually.
I blipped the throttle a few times and all vacuum dropped to 0 and came back to a steady 20inHG at idle. i believe this to also be completely normal.
while car was in i got my infrared thermometer out and got one of the mechanics to jump in and hold it at 2500k rpm. i checked the inlet and outlet temp. of both cats. now, my understanding is that the outlet should be 100oF hotter than the inlet. however, i got similar readings on both....
drivers cat:
inlet 180oF
outlet 135oF
pass. cat:
inlet 230oF
outlet 180(ish)oF
Would this have any bearing on performance?
