well, I get her running. decided to go out for a ride while I got her together. ~mods on car at time 3" all back 16g and clutch. stock fuel. trying to get down to stockish boost levels with MBC. made one boost sweeps to 20. O CRAP turn it down nother pass shoots to 20 O CRAP turn it down. last pass. shoots to 18. pop noise. o poo well nursed it home.........dunno what happened. one the way home it ran but I could not not not get it to accelerate passed 2500 and it runs like total crap. spitting and popping. I'm so angry/scared/upset all at the same time. Could I have popped the motor in no less then 5 boost passes. anyone wanna come help tonite??? I would REALLY appreciate it. |

Double-check all your IC piping clamps to make sure they are all tight. If you are leaking boost and still spiking to 20 psi, that turbo is working much harder than it should.
What kind of boost controller are you using? Depending on the spring stiffness inside the mbc, it can take a lot of turns change the boost or like mine just a 1/4 turn for 1 psi. The closer your mbc's boost source is to the turbo, the less chance you'll have boost spikes. If your source is right at the turbo the mbc sees the turbo's output pressure almost immediately. If it is at the bov line the pressure wave has to reach the intake manifold before the mbc will see it so the turbo being the positive feedback device that it is will keep on pushing for more pressure til the mbc/wastegate actuator tells it otherwise. |
