Mike, after reading about your FABM 13x2 3/4 install, I
checked out Charles's figures on CFM (airflow). As you
can see he didn't post a 13 incher, looks like you may
have plenty of air if your TB is not ported:
565 cfm - B&F stock TB measurement.
If it is ported, you may be close to B&F's stage 1:
Around 640cfm. Below is Charles Smiths CFM calculations
for a 14 inch.
> 14" K&N 2 3/4" tall: 120.89 Square inches (728.96 CFM)
You would probably be under 700 CFM with the 13 inch
FABM. So CFM - FABM match would be close.
