I think JonR was right with the CG response. Sounds like beans. That, or possibly grind, technique or both.

If you're getting a solid puck with no real signs of channeling from a 20+sec extraction but no crema I'd guess it's stale beans.

Hey again guys,

After throwing a relatively complicated mod on my cheap delonghi burr grinder, I managed to shim the burrs closer together, resulting in a finer grind.

The results:
well, I did get a MUCH better shot, around 25 seconds again, but there was a center channel that formed on my naked portafilter and crema did appear, (only about 20% crema though). The puck was yet again perfect. The shot tasted much more like espresso should, with some chocolaty notes like when its prepared at the cafe in which I bought the beans from.

I think I may very well have to fork over the $$ to get a new grinder.

If a finer grind didn't slow the shot, then it must not be the grind setting determining the timing.

Sounds like a pressurized PF, which you've said is disabled.

kind of interesting.

1) Before it was very under extracted, now its as I stated in my post just above.

2) The shot was about 20 seconds previously, its around 25 now, if I were to let it go any longer it would probably be very lungo.

Sorry for the misunderstanding Jasonian.

Hey again guys,

Update:

While I'm saving up for a better grinder, I performed a relatively complicated mod on my cheap delonghi burr grinder, and managed to shim the burrs closer together, resulting in EVEN finer grind.

The results:
well, I did get a MUCH better shot, around 35-40 seconds for a 1.5oz double now, with plenty (70% or so) of dark reddish crema. and it was almost just "drip, drip, drip"; and I got noticeable tiger-striping. Yay, the joys of espresso through a naked pf!

I'll have some pics soon! and maybe a new grinder! hee hee

thanks to everyone that helped me out
