Pierburg EBCS bracket install: isolation mounting
With the Pierburg tightly ziptied to the very solid stock EBCS bracket, I could easily hear it rattling away under boost.
That can't be great on a car with a knock sensor mounted on the block just a foot or two away, so when member Cynner offered a neat, well fabricated Pierburg bracket I ordered one immediately. Whilst waiting for the post I spotted a photo of a 3 port online with a bobbin style rubber mount, which got me thinking...
Using the extenders to tighten the MAP sensor bolt. Note gaffer tape holding the nut in the socket...
Undo the EBCS and MAP plugs to get the vac hoses routed without kinks.
After a few tries with some high density foam carved to shape I finally came up with a combination that completely isolated the 3 port from the both the mount, the MAP sensor and the alternator mount. The zip ties wrap right around the C shaped piece of foam cradling the 3 port, there is an L shape piece to the rear left isolating the MAP sensor, and the other 2 pieces isolate the wiring from the alternator mount and the top of the bracket from the engine cover.
The 3 port plug is double sided taped and ziptied to the 3 port body and all the foam has double sided tape to hold it in place.
I added zipties to all visible vac hoses, cleaned the MAF (used a little Perl to lube and seat the MAF O ring properly), dropped in a new Cosworth filter (thanks Alexei), reset the ECU... And...
Before...
After... an hours driving, city and freeway, and a couple of pulls. Niiiice
So that really reinforces the point of keeping the engine bay completely rattle free and locked down.
My next mission will be to upgrade and neaten up all of the other little bits of isolation foam I've installed on all the covers in the engine bay.
Thanks to Cynner for the bracket and Matt for the isolation idea.
