Later this week I'll get this on the bench and see what if any improvement there is over the first numbers.

The numbers @ 28".......

Ported Exhaust (#4 - port on left) -

• .050 - 35.38
• .100 - 65.88
• .150 - 93.73
• .200 - 113.50
• .250 - 130.63
• .300 - 139.92
• .350 - 146.33

More to come......

"New" exhaust port readings, #2 port - on right

• .050 - 34.98
• .100 - 65.03
• .150 - 93.67
• .200 - 113.32
• .250 - 131.88
• .300 - 142.53
• .350 - 150.92

The reason testing stopped @ .350 was my client is limited to 9mm of lift (.354")



So now the intake @ .350" is @ 197.8cfm, while the exhaust is now @ 150.9, the exhaust to intake flow ratio is now a tick over 75% at peak lift, and over the lift range the exhaust to intake ratio is now about 71.5% (was 61%)
