More HP out of the new 525 EFIs
 
Does anyone have any info on Mercs. new 600s? Can my 04 525s be upgraded? Has anyone put whipples or anything else on the new 525s, and if so what kind of tunes problems have you faced?

The 600 will be like the 575 but with a single whipple and smartcraft.

A guy on our Lake put the whole kit with intercooled intake on his 525 EFI PM me if you want to talk with him.

He said this summer thay are up to about 6-8 kits installed.

Sorry, but I just want to get this up front again. There must be a manufacturer on this board with the info.

Chuck: We are working on a new supercharger system for the HP500EFI and 525 EFI. You can check it out in the tech section.
