NOTES
  • ** Measure engine vacuum at idle ( Engine at operating temperature ).
  • The springs are the same and interchangeable between BV50 and Q BOV but they have different pressures in the different gates. Boost pressures are only an approximation based on intake manifold pressures equaling exhaust manifold presure.
