I never went more than 16psi.300tdi ran a large charge cooler instead of intercooler.

Keep fiddling but you could get to a point where things get very hot quickly.

True, but I've currently got lower temps at the moment, so there's going to be some wriggle room......

Don't touch the boost on the Turbo, the way the VGT works need a lot of setting up to get right and the 300tdi really doesnt need more than 15psi.

Altering the fuel screw will give you an immediate effect,
Unscrew it by 1/2 a turn and see what happens, there will likely be an improvement and you are looking for a little smoke on pedal to the metal on an incline.
having an EGT gauge (and knowing what you are looking at) gives you a big advantage.

I sent my FiP to Diesel Bob and told him of my setup. When it came back to car was quicker than a quick thing in a quick place. Some local lads said I was 'burning coal' when I pulled away from them, prompting me to turn my fuel screw in by almost 1.25 turns.
It's a 300tdi not a race car .....

I wasn't going to touch the turbo, I understand how it works and they are factory set at 18-19 psi. Just confirmed that with Allisport. I'm going to try some adjustment on the pump to see how it is , but think the best long term solution is to get it rebuilt. The EGT'S are down meaning to get the last bit of boost, I'll need a bit more fuel. There's also a little tweak I can try on the timing from my reading on the various forums. Having the pump tuned properly would see to all of this. I need to get saving I suppose......

Been Quiet while my Wallet Recovers.
Have optimised my available settings and it goes very well indeed. 1/4 turn on Fuel screw, timing correct and aneroid set full rich. It flies, makes 19psi at full throttle and the EGT has still not breached 600 degrees, so I'm happy.
I am still getting the Trimphone on speed noise (remember them) above 3000 rpm and at full throttle, I thought it was a leaking bullhorn, but have sealed it up with high temp silicone and if anything it's slightly louder???? any ideas anyone..
I also had an issue with The Rear prop, rear U/J which has been the intermittent driveline roughness I had been getting, so that's fixed too.
It has shown up the shortness in the gearing though and so I collected a Disco 1 Transfer case up in Aberdeenshire last week.
A stripdown has revealed it to be in real nice condition with no polishing evident on the intermediate shaft and case, there was no evidence of any oil leaks, unlike my own unit.
Currently I am considering my options for rebuilding/upgrading this unit, leaning towards Sleeving the case, 300M Pin, big sump and an ATB.

Casings for final cleaning



Chunkier bits than I usually work with



The only issue I found was the high/low selector fork grubscrew was slack to the point of failure, So did the right thing taking it apart to see what's what.

More soon.
