extremely satisfied so far. first off: the sound. no more rattle! just butter smooth inline-6 goodness. it's so nice to listen to the engine at 2k+ RPMs bounce off a tunnel or underpass and not hear the marbles in a tin can sound.
secondly: performance. i wasn't sure what to expect but honestly it feels like i gained 5-10hp. i put zero stock in whether or not i actually gained anything at the wheels but to me it sure feels like it. off-idle power delivery has noticebaly improved. launching from a stop in 2nd gear no longer produces the slight glug-glug-glug as it did previously. deceleration through the RPM band is much smoother as well.
finally: customer experience. A+ to both Dr Vanos (got my order next day since they ship from Austin) and to the guys at Bavarian Machine Specialties here in Houston. John cut me a nice discount on labor and had the original Vanos core boxed up in my trunk and ready to be mailed out for return. as always they offered rides to and from work as needed as a convenience.
we will see how the performance holds up over time but for now i am very happy to finally have my Vanos done.
Cool! also used the DR Vanos kit about a year and a half ago... no problem. I noticed an increase in power too. Mostly improved low end torque
