    Low, Slow building boost?

    Alright, I'm back guys. The car was running great on 18psi and little to no knock. Now, out of no-where, the car is trying to boost to 25+psi. I checked to see if the wastegate puck was stuck and it was not. the wastegate and actuator are still working properly, it's just not opening at...

    yeah it's got a scanmaster on it. we took it up to 19psi and its showing like 2.4 of knock

    closing the wastegate did the trick. it peaks and holds at 18psi now. now the question is. how much boost will the stock internals handle?

    Perfect. That is a great help. You guys have been awesome. Tonight after work we are going to adjust the rod to close the wastegate and then go for a drive. At this point i feel like the wastegate adjustment is the only loose end

    so how to you set the target psi?

    I have another wastegate question. The wastegate that is on there is "Heavy Duty" and we think that means it is good for 18-30psi. IF adjustable, how do you adjust it? is the adjustment made in altering the length of the rod that connects to the actual wastegate? AND, if that is how you...

    that's what i thought. i'm pretty sure this wastegate is about half open right now.

    OK, i have a very basic turbo question. forgive me, my forced induction knowledge is limited to superchargers. Is the wastegate fully closed at idle and when the engine is turned off?

    when the car was running good you could torque brake and spool the turbo up nicely before launching. now your lucky if you can get it to spool to 2psi with your foot on the brake and the gas pedal mashed to the floor.

    YouTube - ‪gn‬‏ please excuse the crappy quality, i used a phone camera. let me know if that is what you are looking for. you can see that i made a vent piece similar to the one you showed me. i revved the motor a little in that video but you sure can't tell at all. i don't have the...

    haha, gotcha. Thats what i get for just teaching myself these things over the years. i named that the "wastegate door/flapper thing" in my mind. I'll start calling it the puck. but that was one of the first things i checked. it moves very freely when detached from the actuator.

    thanks john. when you say the downpipe puck, do you mean that gasket ring that goes between the downpipe and the turbo? it was in pretty good shape and i made sure everything lined up properly before we tightened those springy bolts down.

    should i be able get a tiny filter like that at any auto parts store? I didn't have a chance to make it out until now. I went by a place i thought was 24hrs but they closed at 10pm. i did check the vacuum. it's reading a solid 17-18in.hg. would it be safe to say i can rule out a vac leak?

    Low, Slow building boost?

    Thanks for the pics that really helps me. i will get rid of the oe filter piece and do something similar to what you have shown me. i'm going to get out there and check the vacuum pressure and work on that boost controller after dinner. i'll take some pictures of what i end up with...

    Low, Slow building boost?

    ok, that makes sense. how important is the filter? there was traces of some deteriorated foam on what i thought was a vac cap on the boost solenoid. so i have no filter. this car has a .60 trim turbo, 60lb injectors, and art carr tranny. i didnt say that before, but it should be making...
