This item came in today for flow testing:
A couple of more pictures:
Here’s a link (Extrude honed Audi intake manifold) on Quattroworld to some additional information about the intake manifold and pictures of another manifold that was also extrude honed.
This is an otherwise stock intake manifold, it will be interesting to see how it compares with the other 2.7T B5 intake manifolds that have been flow tested.
After reviewing data from a couple of significantly different cars that were both equipped with the SRM v2 intercoolers I am updating the IC data scatter plot. Bear in mind that the temperature data is subject to some error due to the way temperature rise over a FATS is recorded. The chart should still provide a rough relative landscape of the various IC options.
[notice]Note: On the chart below the Apikols and SRM v1 IC’s are shown plotted on the Y-axis, or zero temperature rise, because I do not have any qualifying IAT rise data to use. I only have flow data for those two items.[/notice]
[warning]To emphasize if it is not clear from the description above, the Temperature Rise data is approximate. Use this chart as a guide, not the definitive word on how these Intercoolers compare.[/warning]
I decided to pop the top on one of the 6 stock intercoolers I have laying around taking up space. I was interested in trying to evaluate the flow distribution through the charge rows and to see flow reversion in action. Flow reversion refers to the airflow being sucked back through the core. This apparently may happen at the charge rows nearest the endtank inlet.
In the short video the bottom of the core is where the inlet is located.
