Adaptation Run - No long "uphills" in Chicago! Posted by Bill Homer [Email] ![]() ![]() |
I am trying to debug the turbo boost on my new-to-me 1994 9000 CST Manual (full-pressure turbo with APC), which is only indicating about 2/3 into the yellow zone on full throttle. I do not hear a "whoosh" when I get off of the gas pedal. I believe that these signs indicate base boost only.
So far, I have replaced all the "normal" vacuum hoses (with thick-walled silicone) except the ones going to the gauge and the charcoal canister (they look OK), put in new NGK plugs gapped at 1.0mm, running 93 octane premium fuel. Note that the hose running to the MAP sensor was torn, so I had to replace it with thick-walled silicone hose of approximately the same length (there was a warning not to replace this "precision" hose, but I can't see why silicone would not work). The BPC solenoid was cleaned out with WD40 and buzzes when the car is running.
Now it's time for the "adaptation run". Unfortunately, there are no long uphills in pancake-flat Chicago, so I am wondering if anyone has ideas on how to bog the car down to allow the required 3 seconds between 2750 and 3250 RPM. I know not the use the brake pedal, as this activates the dump valve. So what alternatives are there - use the emergency brake?
