Like to get critical feedback on the runner entry - see attached.

The height from the plenum floor to the top of the entry is 1.5"

Runner ID 2.125" as the lower section

Runner entry OD - top surface before the edge rad is 3.17"

Distance from the top of the runner to the bottom of the blend is 0.81"

The application is a Vortec4200 inline 6 on boost. This is a redo of the existing plenum which was constrained in space (brake booster) that is no longer in the way.

I'll post additional details as I go..

Thanks

This thread has lots of good intake theory's.
Also the pics of Fast's LS1 truck intake with the lid off I think best shows the qualities of a high flowing and equal distributing intake. If I were to make an intake I'd copy their intake as much as possible.

 

Guess I should have posted in the intake sub forum which I did read end to end.

The link to the fast ls1 appears to be broken.

 

Here's a good article on intake design - http://www.profblairandassociates.com/pdfs/RET_Bellmouth_Sept.pdf
