Missing Boost

pokeyl

Did not work, as soon as SC fluid got up to temp boost fell off 6 PSI max and starts to build after 4K (1.5 to 2 PSI) and you have to twist past 6K to get to 6 PSI.

When the fluid is cold I build boost at 3 PSI at 2-3K...

Worked good 75F OAT for 45 min, 60-70 MPH. As soon as I hit city stop and go oil got to hot and boost fell off.


I am going to work on adding airflow to the coolers fan system.


Note: the under hood temp will burn you on any item you touch. The SC fluid in the tank is 155-160F (after a 1.5 hour heat soak drive and a 15 min cool down)
I took me 15 min to find my thermometer.

During the 15 min cool down the oil temp fell from 220 to 190F. If the SC fluid fell the same amount, my max temp is 185-190F is over the rotrex 175F limit.

Just got back home and spent the last 10 hours changing my SC unit. Fluid looked BAD milk/gray. Hope this fixes the boost falloff problem.

Then I can start back on this!
