Couldn't get to one of the nuts, so the Hamma For came out.
What's a Hamma For================= it for hitting things  ;)

Turbo now has studs, flange nuts, lock nuts and thread lock, that should sort it and stop the thing coming loose and blowing a gasket.

Inconel locking nuts..

Race 1 from Sunday with full race commentary . Still running with low boost and then even less when a Turbo gasket blew a few laps in !.

Looks like the bigger issue was that I used bolts rather than shouldered studs that I have now used.

If you look at the bolt you can see where the turbo has chattered the thread away, it could actually be that the weight of the turbo is not helping, so we are also going to weld a heavy support strap to tie the down pipe to the exhaust manifold.

Double stack
Get shouldered bolts and the locking studs
Grayo was having terrible trouble
Been perfect since

Its common on the 5 turbo conversions.
After blowing a gasket and finding loose nuts i swapped to inconel exhaust studs and the aermotive nuts prob 2.5 yrs ago and countless trackdays no more issue. Ive snapped x2 downpipe supports on a large 3" downpipe attached to turbo that ive given up trying to support it.

These pictures popped up.
Martin Renolds and his Escort has become a bit of a nemesis over the last couple of years as we seem to keep occupying the same piece of track, mind you he has been winning a lot of races this year, mind you the car really has the best of everything though and is just one of his four race cars.

Anyway, hopefully with a bit ore power we can stop this both occupying the same piece of track thing ;) .

He was certainly hassling you at Brands!
Fingers crossed a bolted down turbo helps create a bit of distance your way

Some good pics there. Good to see it running aye! Jamie mentioned some good aero info earlier on also :occasion14:

With the turbo/exhaust situation. I have heard good things about those nuts. But Nord Lock washers also help the situation a LOT!

Got to go with what I have.

The Studs are 10mm which is normally 17mm spanner size, my problem is I need 10mm with 14mm spanner size!

Surprisingly, this is due to the size of the Turbo ;)

I had a google and you can get locking nord washers..
