The good: Car starts up and and warms up, and drives great.
The bad: when under load the temp gauge lowers about 1/8th of an inch under heavy boost. I'm only running around 7psi for break in. I also have a tiny coolant leak, very tiny. and a low temp thermostat from ATS. after a few seconds of driving normaly (no boost) the car begins to creep back to normal temp, and it will remain there. Even at a stop light. So I don't know if this leak under boost is causing the temp gauge to read incorrectly. Perhaps an air bubble created from the leak is causing this? Just need some thoughts from you guys. Any advice would be appreciated. Issue #2: When the car is at idle it's reading around 15 vacuum, I'm under the impression that this should be more what 21. From time to time the car will idle around 1100, and when it does the vacuum is at around 20. The idle will drop to about 600 when the car reads 21. Scenario: I stop at stop light car idles at 1100-1200 with vacuum at -20. After about 30 seconds car sputters slightly, and vacuum raises to -15 and idle drops to 600ish. WHAT'S THE DEAL WITH THIS!!! --------------------  |

I ran a test tonight after work. I warmed the car up all the way and gave it a couple of non-boost revs...only to around 2500. I squeezed the top coolant hose before and after and it felt the same. I then boosted across the parking lot (temp gauge fluctuated), parked the car and checked again. After I boosted I felt the hose and it was really tight. I also noticed that a little coolant had leaked right at the water neck.
The odd thing is that after the heavy boost the car idled at 1500 and backed back down to 700-500. The vacuum during this time period moved from 21 down to 15. When it hit 15 the car was idling at 500ish. -------------------- |
