pump top inlet/outlets

panyan · 19 Feb 2012 at 19:00

i have a D5 with alphacool top which has both front and side inlet/outlets

i thought using wither would be fine, but then i read:

Side Inlet Performance

I did experiment with side inlet performance with my initial discharge only pressure testing and found that performance suffered significantly to the point where the stock top performs better in many cases. I didn't retest these side inlets in measuring total head, so I have pulled those results, but I expect them to scale similarly and the stock top performs nearly as well as any of the aftermarket side inlet tops. There is a significant loss in the 90 degree bend.

I would not recommend using the side inlets unless you absolutely have to.

is there any truth to this?

I believe there is. Said something about it with EK tops. I'll have a dig
