Turbo Upgrades for the GUIV TD42Ti

[jff45]

What was the pump finally set to? What is considered as factory setting?
For example, my factory setting on my TD42T was 0.56mm and I set it at 0.70mm. I hadn't heard of pump timing being expressed in degrees before.

Good write up too!

Is that what Mat and Old Mav meant of Diesel Dark Arts:-)

Dark Arts indeed mate. Andy was clearly very surprised. He was very happy with it too.

Sorry mate you are right. It was late last night and I figured that was the measurement. Your right, it was off a dial gauge so clearly not a degree measurement. They were talking about rotating so I called it degrees.

This was all outside my knowledge base but the pump was 2.5 points out. From memory yesterday I think Mat said factory was up to 0.6mm and I was 2.5 point outside that so assume it was 0.85mm. I'm not sure how far back it was retarded but under 0.6mm. Given there was a big question mark as to whether it would be worse or better I can't imagine they went back much more than the 0.6mm limit.

What a change!!! I will post up the Dyno print outs today.

So here are the tell all sheets!

All reports show the Blue line as the Drive in Baseline measurement.

First report is tuned to 108kw and 393Nm of Torque. Note the steady climb in power peaking at 2620rpm. I was making about 60kw at cruising hwy speed of 2000rpm. Not ideal. I'd be forced to tow in 4th just to get into the power band

First Tuned Run. No pump timing check



Bit the bullet and retarded the timing back into factory specs.

Ta Da!!



Quote "Takes a lot to Impress me..... I'm Impressed!" Completely moved the power curve back into position. Boost came on and stayed!

Epic!!

So by now the car was suffering from Heat Soak and every Dyno run was loosing so we had to rest it to cool.

Bloody happy though.

Here is my Mock Up of the 3 runs over each other. Sorry I did not get the 16g run but it's basically the same but earlier.



Holy Bjeezus!!

I think Mat has impressed Andy a few times now. He keeps getting results that are beyond his expectations with the turbo and pumps that he has chosen.
Top results yet again Mat and I'm glad Andy did not try to talk you out of following Mat's advice over his own. The customer was definitely right this time.

It was set at 0.76. Factory timing on the Ti is 0.46. I did say to set it at 0.5.

The ti pumps with there basic electronics are an odd thing.

Even so a lot of this is still Andy's efforts. This is what makes him a good tuner. He is happy to try different things without making a fuss. He didnt have to do anything I suggested yesterday I am just a nobody and I wouldnt have been upset if he didnt take it on board, it is after all his business.

I always recommend him to you guys down there and each time he delivers. Again its a fantastic thing to have someone with his knowledge that is also accepting of feedback and suggestions.
