I have a 1991 integra with ls/vtec turbo. set up is stock head, je piston eagle rods other bolt on, 750cc injector log manifold t3-t4 turbonetic turbo, civic Aluminum Radiator. new water pump, and oil pump. motor has 1500 miles on it. it put down 345whp. when i drive around on the street it runs normal temps. the oil temp sometimes gets to 210 when it hot out. i ran it once at the dragway (new england dragway) and the coolant and oil temp. spiked. i have S300 but no laptop so no datalog to see how hot it got. Why did it get hot. Didnt blow heat gasket no cooland or oil leaks. I drive the car everyday and dont have any issues with it. any help would be greatly appreacted. thank you

 

maybe the radiator isn't cooling enough under load. take inlet and outlet temps while overheating

 

do you have a t-stat

do you have a slim fan if so is it blowing the rite way

 

I have a t-stat. its a 186degree.. i have a slim fan, it is blowing away from the rad. not pushing threw it. it runs cool even in traffic. and doing highway pulls. no sure
