I may get beat down for this but...

Does anyone run a dynoport big core barker on and 800R summit or the 600ho sdi summit? Just curious if there are any noticable rpm gains over an hps or other cans at altitude? Let me know how they work if you have any experience with one on your sled.

Tried 3-4 differn't cans head to head but not big barker. All the ones we tested were similar or hard to to tell much diff. I settled on the HPS for the sound,weight and performance on my 860.
