Understanding EGT Temp.

[Vinnie]

I'm trying to understand how EGT temperature works, after doing a lot of research and reading this is what I've come up with, and please correct me if I'm wrong, I don't want to blow up my engine.

High EGT Temp. means the car is running lean, and Low EGT Temp. means the car is running rich, am I right???

I also read that for the car to propably tuned the EGT"s at the end of the 1/4 mile should read around 1600F, is this right??

So...If I'm doing the 1/4 mile, and by the time I get to the end my EGT is 1500F does that mean I'm running a little rich and I can turn up the boost a little???

If that's the case, then by the end of the 1/4 mile I'm going over 1600F, I should turn down the boost.

Thanx for the feed back.

for egt to lean can cause high EGT to rich can cause high egt.

it should be use with a logger setup.

i don't tune my car on egt alone.

Also need to consider that if EGT's rise really rapidly, odds are that you are knocking quite severely and should get off the gas. I like to tune to around 870C at the top of third gear.

Ignore the stupid stuff people say in that thread, but read everything that 95GSXRacer and a few other guys typed.
