Induction Questions
How much air (cfm) can the stock Throttlebody flow?(L98 and LT1)
How much air can the stock MAF flow? (L98 and LT1)
When I see 53mm throttlebody, is that the size of both openings, or is each opening 53mm?
Thanks

Re: Induction Questions (DarthD)
The stock MAF flows about 550cfm or so, modified with fins removed it flows about 750cfm.
Stock TB is in that 500-600 range, but i cant remember the exact number. A 52mm TB flows 750-800 if i remember correctly. I do know that a 58 flows 1000.
Unless you go with a bigger engine, 350+ci, you do not need the bigger TBs.
