Does anyone know where I can find flow numbers for the different TPI bases and also for different runners?

Thanks

Runners (measured individually)
Stock....................203.17 cfm
ACCEL................242.02 cfm
Extrude/ACCEL...275.83 cfm
Super Ram............289.18 cfm
Intake manifold with 3/8 inch radiused intlet
.............................222.45 cfm

Stock intake manifold with runner
Stock....................198.72 cfm
ACCEL................213.52 cfm
Extrude/ACCEL....217.11 cfm
Super Ram............220.67 cfm

ACCEL Hi-Flow intake manifold with 3/8 inch
radiused inlet.........251.51 cfm

ACCEL Hi-Flow intake manifold with runner
Stock....................215.83 cfm
ACCEL................232.53 cfm
Extrude/ACCEL....243.21 cfm
Super Ram............240.24 cfm

Extrude-Honed ACCEL Hi-Flow intake
manifold with 3/8 inch radiused inlet
............................275.83 cfm

Extrude-Honed ACCEL Hi-Flow intake
manifold with ACCEL runner
............................266.94 cfm

Edelbrock Performer RPM manifold
(Stock)..................286.51 cfm

Edelbrock Victor Jr.
.............................275.24 cfm


My guess is that the Scoggin Dickey Vortec TPI base will flow the same as a edelbrock once it has been de-burred (alot)

ZD1, wow, that's a lot of info. Do you happen to know if these tests were all done by the same individual?

What was the depression for these flow numbers? 28" ?

Dryseals

Flow numbers are always great, but they can be very miss leading. If the engine had a continous flow through the runners and manifold it could tell you alot, but it does not. What happens to the air flow when the intake valve closes?
