Posting today to follow up on the car and my continuing education with my boosted FX.
I can confirm we have absolutely taken care of all vibrations and noise. Every vibration I identified, each rattle and noise was hunted down and eliminated. Most of them were in the exhaust system. The fact that I put down Dynamat inside so much of the interior has actually improved the noise levels better than OEM, I would say. Even on full boost, the car is devilishly quiet. Anybody I have given a ride says exactly that, "man - it's so quiet!". Road noise, wind noise... all better than before.
One added bonus is that I have some additional feedback to the amount of torque I am throwing into the drivetrain. Get this - when I go WOT, the force of the motor actually flexes the drivetrain/motor mounts enough to move the shifter back in my hand - maybe 3/8 of an inch. I drive with my right hand on the shifter and I can actually feel the torque I'm asking the transmission to swallow. I've started using this feedback as a way to limit how often I ask for maximum power. This is a function of acceleration so if I accelerate at the same rate for say, 10 seconds, the shifter moves back into my palm for that long. When I release the throttle or give it a little less gas, the shifter responds by moving away from me - back to it's un-torque'd position.
Finally, I have also noticed that my daily driving has seemed to smooth out. Maybe this is because of the fuel learning function or me just getting used to the car? Shifts are coming more predictably, and I'm not accidentally boosting when not meaning to. Maintaining the car's speed takes less input from me than before the turbo - it almost seems as if the motor likes to maintain it's speed for much longer now. Coasting on the highway for long distances seems to take very little throttle input.
I have also had the chance to get out to some lone open roads. I have found this car is ridiculously fast from a rolling 20mph up to 100mph. It's still fast from a stop, but I can tell that I have moved 60-70 feet before the boost really makes the motor pull beyond what I have been driving for the last 6 years. This is the only lag I have ever really been able to identify. If I am going anything over 35mph and I want to pass somebody - it's done before they can even react. Instant boost and passing like they were standing still.
I know, I know. You guys want a video. Well Jcas should be hanging with me this weekend for a show I'm entering. Bring the camera, J - I know you want to go for a ride!!!
