WBX test rig

Post by silverbullet »

I've been building this to test fresh rebuilds prior to dispatch.
It's built from an engine stand, bellhousing and a custom starting loom by syncrosport (all kindly donated by a grateful customer) and then modified by me to allow quick loading.
The mast has been extended 200mm to match the height of the shop engine stands, so it will make for a no-crane easy swapover using our elevating table trolley.
There's an efi fuel pump, filter and the fuel tank is an old Jaguar XJ-S swirl pot (holds a good couple of litres+) and the battery all mounted down below.
The radiator has yet to be added: I'll use a T3 one below the bellhousing, but inverted to put the hose connections in a favourable location. It won't be a problem to air bleed!
Just needs a small "dashboard" panel up top to keep an eye on things and some brackets to hold up the engine loom, then it'll be good to go.ImageImage

I think that should enter service in a blaze of glory by having the wbx6 as its first recipient.

Very nice, toyed with making something similar myself but didn't do enough rebuilds to justify. Will make testing a breeze though :ok

Thread resurrection!

After too much faffing with wiring harnesses dangling all over the place, I ended up welding the coil/relay bracket to the big coolant pipe, along with a support for the header tank.
Just the Ignition switch to properly fix and a bracket/platform for the ecu.

I have a 2.5 about to go to Edinburgh so I cant afford any problems prior to despatch!

Currently sat full of coolant overnight to check for any seepage before any oil goes in, then I'll put some 20/50 Comma Classic ( high ZDDP) and spin her up with the plugs out to get some pressure on the gauge before first firing.

Or to find out that the dissy drive is 180 degrees out :roll:

We are a bit cramped atm due to an unexpectedly large drying cabinet that came with our new ultrasonic cleaner purchase...

That’s awesome! Nice bit of kit.

Can we have a video of a test perhaps. We only want to hear it really, don’t need any detailed commentary. Cheers

I envy the air-cooled lot sometimes with their simple set up, bare engine tests. Mustie1 on YouTube and the like.

Customer has asked for a clip of it running, so will do.

The one thing about a wbx when fully dressed is that it suffers from what I call Porsche/washing machine syndrome: the basic core engine looks great but with all it's clothes on, it's no looker :?

Agreed. It all gets a bit busy when fully dressed. They sound great thought, especially with a nice stainless exhaust. I’m unsure whether they should shake a bit, even when warm or whether that’s just because the pistons are boxing? We’ll soon see I suppose.

Here’s mine for reference. Just a measly 2.1 MV, nothing posh like these nice 2.5’s.

I still have (one of several) back-burner projects such as a cast alloy plenum similar to the wbx6 one, which would give a nice focal point in the engine bay...
