Ever since i boosted my car warms up REALLY quick, i noticed this since the first day i installed my turbo, but thats probably normal. I always have my fan on (just to maintain temperature) Sometimes when i do a pull, i can see it get noticable hotter and it will slowly start to go back down, it always seems like i'm fighting a battle to keep my car cool Whats going on guys? My air fuel ratios are 12.5 (+/- .5) while in boost. I dont think i'm running THAT lean now am i? Is this normal?

 

FRESNO get pretty hot. How's your thermostat? Still using stock fans/radiator? Maybe try bleeding your cooling system. What are you using to monitor your A/F?

 

Sounds like you need a new thermostat or your fans aren't turning on.

 

Like i said my fans are always on, but the thermostat... Hmmm doesnt it stay open if its bad?

 

Bump

 

I think it can get stuck either way. I wonder if leaving the fan on while you're moving will prevent more airflow than take in?

 

If it's staying stuck, then it won't allow it to go to the radiator for cooling.

 

I'm using a techedge wideband with palm logger, so i should change thermostat?

 

Yea, change it, they are really cheap and easy to change, and you might as well change the coolant anyway.
