umonkeyz 0 Posted March 9, 2010 hi, what size cda are people running on their vr6's?? ive basicly just bought a second hand bmc cda, which was apparently fitted to a vr6 by the stealth company. however on recieving it it appears to be only the medium size cda ie, code cda85-150 which is for engine size over 1600cc, and not the largest size cda100-150 which is for 6 cylinders. do you think this will make much differnce? i mainly just want a nice engine note, but for the price i dont want to have a reduced airflow (compared to the 100-150), i can handle a few % less airflow i suppose. just tell me it make no odds and ill be happy, lol.
