Dead topic (i know already!!) ???'s

I am about to purchase the Accufab Plenum , but have a question about the throttle body. i curently have the BBK 70mm TB. Should i stay with it or bump it up to an accufab 75mm TB. Any input is greatly appreciated.

stay with the 70mm. the accufab actually loses airflow with the 75mm. flows 628cfm with 70mm and like 618cfm with 75mm.

Naw you will be Fine you only should go with a 75mm if you use a S/C so 70mm to a accufab Plenum will be fine..

Yeahh...thats what I'll do. My engine has over 73,000 miles on it and i don't think it can take the amount of air induction that a S/C will produce.

Thanks.
