XUD Compound turbo project.

[Chairchild]

Dissertation subject for my BEng degree in Automotive Engineering I was supposed to have a budget of £50, but the engine rig itself ran to over £1k in costs, lol. Machining time for the rest of the controller was estimated to have "cost" about £5k, if it wasn't done by the uni technicians in the workshop.

I've got a Diploma in electronics engineering too, so avoided doing a proper ecu, because I knew it *could* be done. And where would the fun be in that?

I don't have any clear pictures of the final complete engine rig - but I've got plenty of the build:











Annoyingly, the proper controller STILL lies unfinished... it's missing the two link rods and cam setup



So this was thrown together instead - preload was adjusted with washers/turbo bearings, lol






And yes, any vnt control is unique to each engine/turbo combination. You wouldn't believe the amount of people who fit bigger/hybrid vnt turbos to a remapped car, and wonder why the ecu throws a wobbly! But keep an eye on this fella:

As he's in the process of manufacturing standalone vnt controllers, which can be easily mapped to suit your setup
