Rev Hang issue below 3000RPM *after* golf tee mod.
The rev hang issue had been bugging me on this car for over a year. ( see my other video.. it was gnarly. )
Did golf tee mod and this problem is now 1/2 the intensity... ffffffff yeah :)
Will cap the vacuum reserve line at the intake manifold & if it makes an improvement, will post another YT video.
Drivetrain: Stock 2.8 M52 motor w/177k miles.
ECIS CAI, Fan Delete via PWM Spal electric setup.
Car sounds a lot better.. lost a tiny bit of low end torque but the low, rumbly Exhaust sound makes up for it :)
135i "Golf Tee" Mod
BMW uses a vacuum operated flap in the Exhaust to alter the sound of the Exhaust at low RPM. Normally, this flap opens over 3,000 RPM, but with this modification, you can keep it open all the time.
1996 BMW 328is "Golf Tee" Trick
This is what my car sounds like after doing the "Golf Tee" trick to the factory Exhaust to help the car have louder growl between idle and 2500 rpm. Thanks Pirate for the help...link to thread for directions: http://www.bimmerfest.com/forums/showthread.php?p=2593470#post2593470
