Need some info form the 8g turbo owners.
I installed the turbo last week and tuned it right in. The Galant has been running absolutely outstanding! I Flashed the ECU and barely need my AFC NEO until around 4500 RPM. I have been running the cam at a 2 degree advance, with the ITC retarding the ignition timing 3 degrees anywhere past 4500 (until I get to a dyno). No knock, leaks, over-boost, MAF issues (from the BOV), idle problems, transmission slip (auto), leaning at WOT. The G is so fast I am a little shaky after I bring it home from playing. I really want to see the power I am putting down, I am hoping like 215-235. I am not using the AVC yet and want to make sure all is solid before I push the boost to 10 psi. I am running a STEADY 7.5 psi, where I thought I might run into problems because I plumbed the exhaust myself (from turbo to after cat). The automatic transmission is great at keeping the acceleration and boost while shifting, which is smooth. I do not even need to downshift into 3rd to clime hills or just general acceleration. Just lay the pedal to 20% throttle position and it takes off.
My only concern out of everything is my exhaust gas temperature. At idle the EGT is around 900-1000 degrees Fahrenheit. Low load and coasting, it is around 1200-1600F. At full boost it rises to around 1700F and gets no hotter. Is this normal? I found no posts on EGT for boosted Galants (mine a 2003 4G64 8G) and want to know what you guys are running. I am ordering a turbo timer some time this week and have been letting the car idle to 900-1000F until I turn the engine off. I am running a high flow catalytic converter and am passing the OBD II emissions test on my code reader. Could the cat make things hotter?
I am running the car at 10 AFR to keep things as cool as possible and am running through gas like mad (270 miles a tank). I set the AFC to enrich anywhere past 25%TP/4500 RPM because of the high heat weather we have been having here. I will wait for the advice of the dyno operator on this because of the high EGT.
Please get back to me on the EGT, or any questions you may have and thank you in advance.
