its looking good Jeff. Have you done another new exhaust for it? looks like a side pipe out through the sill?

that hose on the turbo outlet always felt a bit dodgy when putting it on, but it never gave me any trouble even on the higher boost.

Can't shed much light on the oil/breather issue either. I only ever really used it at hillclimbs = about 980m at a time & never had any problem. It always had a little bit in there at oil change times though.

The only times I took it to a circuit, it blew a diff on the first hot lap I ever did in it at Morgan Park. Then at QR it lasted about 5 hot laps before the turbo fell off. But it took 2 sessions to get those 5 laps out as it would also start to get hot after about one and a half laps... so I had to alternate between hot laps and cool down laps to keep the engine temp under control... This was all on the high boost (1.5bar or approx 23psi) tune Andrew had.

Going to 1 bar with a nice safe tune and pump gas sorted both the overheating and the turbo stud problem. I also milled the turbo manifold flange flat (it was about 2.5mm out!), helicoiled all the stud threads, fitted new studs and K-Loc nuts.

It then survived the Supersprints at Carnell with no problem whatsoever and ran 1st in class & 6th outright. It was a short circuit though, 4 laps of a ~1km track at a time. Not sure how many laps you do in a session over there?

its quite possibly an issue like the RB26 has - constant high rpm buils up oil in the rockers and can't drain back quick enough. Their fixes are an oil restrictor in the gallery to the head, and making an external drain to the sump.

If you want ever raise the boost back up, get some inconel studs first. Those metal lock nuts should be replaced every time too. which reminds me -send me your address again so I can post that laptop. I am soooo slack!
