Since it's been a mostly nice day today I've been outside tinkering on the SD1 trying to remember where I'd left off on the turbo conversion. I welded up some fittings and connected the oil feed and return lines, replaced a rubber fuel hose underneath, charged the battery and turned it over. After some cranking and a tickle of throttle it burst into life and immediately settled on a smooth fast idle on old petrol. I've had it start and stop a few times, all seemed good so got the camera out for one last run before leaving it to cool down because of the lack of radiator. All went well until the last couple of revs for the camera when it decided that lots of white smoke would be fun! This could be a number of things where I've just thrown it together just to get it to run. First thing to look at is the oil flow/pressure to the turbo. It's an AN4 line directly off the oil pressure switch port on the oil pump and pumped straight into the turbo. Secondly is the oil return line, which has quite a shallow angle to the sump, and is about 1/2" internal diameter at it's narrowest point so could also be the culprit? There's also some play in the bearings on the turbo. I have another Holset HX35 somewhere which I'm sure has perfect bearings and didn't produce any smoke on another engine I have it fitted to. But on a positive, I now have my SD1 running again, and it has a turbo hanging off the front

Just like the Mad Max garage scene.

I don't know about any of that but i must say that sounds fcuking evil . Just like the Mad Max garage scene. Love that film! In reality I can't tell you how quiet it is now, there's more noise from the engine up front than what's coming out of the exhaust. It used to be borderline embarrassing how loud the exhaust was and yet moderately slow with the RimmerBros sports exhaust! Now it's looking like it's going down the stealth fighter route, I'll be creeping up on people then wailing past on boost

Bump.
don't know how i missed the last update, but sounds wicked with the turbo on there.
What setup are the headers on this? A previous photo shows the turbo sitting on a manifold on the LH side, I'm presuming it has a crossover pipe from the other bank?

There's a crossover pipe underneath routed so that each bank supplies each scroll in the turbo, probably not the most efficient, but should sound good once it's all up and running . Trying to package it all in is proving the biggest headache, so I'm close to converting the engine to serpentine as that'll give much more space and better positioning of the ancillaries to pack it all in place under the bonnet. I don't know about any of that but i must say that sounds fcuking evil . Just like the Mad Max garage scene. Exactly my thoughts, MadMax 1 garage scene, "Kick it in the guts" Love that movie

An SD1 vitesse turbo on banded steels? You’re winning at life. I love it.
