Custom OEM DE Plenum/powdercoated/Z1 plenum spacer
I have for sale my custom OEM plenum. It is a Z1 Motorsports powdercoated upper plenum, Z1 5/16 plenum spacer, and custom grinding/smoothing of all interior surfaces on both the upper and lower plenum. 5mm was removed from the top of the front two runners much like the MREV2. Machining was done at a local machine shop. I am asking $400 shipped for the whole package.
This is a dyno plot of what I gained with the custom grinding and smoothing. Gains are minimal on the DE, however they are consistent throughout the powerband and and I would expect a REVUP to see great gains with this plenum/spacer combo. After changing up exhausts, I saw 275rwhp/260rwtq when matched with this plenum and headers. This plot is before the exhaust change:
Mods, I had some computer issues and couldn't get these uploaded until today. Please let me know if I need to update the date.
This does include gaskets (used) and hardware.
These photos are from the day it did the install. You can see the comparison to what an OEM plenum looks like.
Please let me know if you have questions. Thanks for looking!
