I just finished my new setup for this year. i am now running a topmount with a billet t67. The only thing that has changed is the turbo kit. still using the same tune as last year until i get this issue taken car of. I did switch to a civic radiatior and had to mount the fan on the front on the radiator. The motor is an ls/vtec sleeved 83mm. it made 450hp last year without any problems ever.

So the problem is that i am reading crazy cooling temps at idle. it can reach 199-200 on idle!! and 220+ just goin around the block on no boost. i replaced the thermosta and made sure to get all the air out of the system. After draining and refilling the radiator many times....i decided to take it around the block to see how it reacted. the datalog is posted below. the motor sounds fine and doesnt sound irratic like the datalog would make you think. wtf could be wrong?!?!?!?!?

HOW DO I POST A DATALOG???

 

Is your fan now pushing instead of pulling?

 

fan is pushing. i can post the datalog once i figure out how to do so....

 

Sorry to threadjack but I'm having the same problem also. Looking for answers too. Almost identical setup which involves a topmount and fan pushed style with a civic fluidyne in a db8 integra.
