Early 2000s intake ports

[Ccr252]

Does anyone have any insight to what kind of flow rates the early 2000s intake ports were getting?

I don't know which year engine and neither which engine but just in case it will help calculations of air flow. Qouting from "FI fantastic facts - 2013'' When running at maximum speed a formula one engine ingests air at a rate of 0.40 KG PER SECOND for combustion of fuel.

Is that quote referring to the 2013 (turbo hybrid) cars? If so it doesn't help much, because converting mass flow to volumetric flow requires knowledge of air density (pressure and temperature).

(The ability of a port to flow air is expressed as a volumetric flow rate at set atmospheric conditions. That volumetric flow capacity is only slightly influenced by air density - unlike mass flow capacity.)

Converted to the standard dry flowbench 28in/H2O depression, back of the hand calculation is 275-280cfm for the V10s, 300-305cfm for the V8s. Obviously there is more to it than dry mass flow at 1psi depression, but that will give you a ballpark reference for comparing against most tuners / magazines / hot rod books, etc.

"I don't know which year engine and neither which engine'' Could not make out from source quoted. But common sense shows source quoted date was 2013 so that quote could not have referred to (the turbo hybrid) but to the NA engine before that.
