ok ive got it to stay with safe operating temps when I drive as long as im not boosting past 1-2 psi. but when I jump on it the temps go up 17-18 higher than they should be. goes from 96-97 to 114C. any idea on what would make it run ok when not boosting but when i get on it it causes the temps to rise so high? thanks!

 

Make sure your water pump isn't slipping at high rpm. The higher the boost the higher the stress on the coooling system, but something isn't 100%. You meanh 11-12 psi i assume?

 

i have other problems with my car at this time. its boosting around 5-6psi. but either way, when im at high rpms and boosting it gets hot. how do i tell if its slipping or not? I believe it has the Greddy pulley on it fyi

 

yea same thing with me... but i just got a reman water pump because my other one went out... n now i can hit it in every gear wot except 5th if i keep going in 5th my temp gauge goes up..... n im getting a fluidiyn or how ever u spell it radiator

 

Check that all the fan relays are working.

 

are you talking about the pump itsself slipping or the pulley....im pretty sure mine is doing the same thing, and i have a greddy pulley on my water pump
