Been a while yet again.

Still havnt sorted the fault code issue. Still very rarely does it and only does it when engines cold. Friend of mine has suggested that the hp pump could be worn and it takes warmth in the pump to reduce tolerances to a level its happy to be ragged.. Quiet feasible i think so basically just stopped hooning from cold [emoji23][emoji23][emoji23]

Finally got my exhaust temp and back pressure gauges fitted aswell as a dedicated diesel boost gauge. Copper work looks more like it belongs on a hillbillys still. Took the opportunity to sort some piss poor wiring out behind the dash aswell so thats all now nicley soldered and heat shrinked.

Figures gathered were pretty reassuring too after being scare mungered by a few individuals to the dangers of mech vnt. Cruising at 60mph temp stays at a solid 300 deg c generating 7psi boost with 10psi back pressure. Actuator has been tweaked to open the vanes at 18psi giving a max peak of 30psi back pressure and a spike fluctuation of 20psi boost, 38psi back pressure which is well within the 60psi danger zone i was advised. Absolutely hooning im able to bring the gas temp upto 800 deg c rapidly but thats foot flat like a mad man.

Got that lower leaky rad pipe changed too. Safe to say it was pretty obv why it was leaking, was litturally just scrimping towards the end of the build.


Managed to get a wheep bearing to give up after a few launches aswell

And so to my most recent problem. Been having issues with the gearbox bracket for the turbo. Had it fail once, not surprised at all, was an absolute lash up in situe to get the car driving.

Gtound all the shit mig out and sat at work tiging the bracket back up. Ended up triangulating it for extra strength
After this the two m6 bolts that it was originally designed for failed. wasnt surprised, poor choice of mounting point and used stainless m6's like an absolute fool. Ive now further beefed up the bracket to add an additional mounting point. Further triangulated the frame and used high tensile bolts on all fixing points.

Its been suggested that heat expansion and vibration is the primary cause of this failing and that i should fit a flexi pre turbo after the collector in the manifold. Now ive never heard of a flexi in a manifold so im very sceptical atm of this idea and concerned it may not hold the temp and pressure.. Opinions???
