Bring the test mule to surf and turf?
I'm fine tuning the last pieces of the B.O.M. (build of materials) and I'm not including new brake check valve, grommet and vacuum hose. I'm just trying to eliminate various potential issues. But I also made a link for those not going the turbo route:

Maybe this is where my “moaning” sound is coming from around 1800 rpms. Almost sounds like a trumpet being played under water.
A prolapse could also do that if you don’t have the toilet seat down first![]()
Been hanging out on the weird end of the interwebs again aye?
Really I’m about to upload a video to a new thread. I’ve research the hell out of the forum and can’t find an answer
Exhaust leak?
No, happens between 1800-2000 rpms. I can feel a very minor feedback in the accelerator pedal, coming from under the hood towards driver side corner, seems to be more often and intense when cold... deff sounds like a prolapse in the toilet, I guess. Trying to figure out my imgur problem now so I can upload the video
And no braking issue?
“Trumpet” sound between 1800-2000 rpmAnd no braking issue?
No braking issue. Sound doesn’t change pitch or volume when steering or braking.
There is already a test mule but not using all of the production parts. That is coming up very soon.
