Not quite sure what youre saying?
Plenty of Td5s out there running 2 bar +.

My understanding is that around 15 to 18psi is about right and that 21psi and above is in the 'overboost' region.
2 Bar is 29psi and looking at your boost meter reading, you are around that point (just below @ 28psi) - which is 'overboost'. My understand is that Td5 engines have an inlet manifold air pressure sensor that feeds the ECU, this sensor is known as the MAP/IAT and also measures inlet air temperature). The ECU will cut fueling when detecting an overboost situation passing the MAP sensor. I also understand that you will need to ensure the exhaust manifold studs are good and that you don't blow the head gasket or overheat the engine/head etc.

I believe you need to remap to get over 20 and that 22psi is the majic number where any higher gives little to no return (ie the power curve goes flat) and can/is likely to damage the engine.

I look forwards to being corrected :)

All correct, for a stock TD5...... My 110 is far from that, all listed in this thread.

  • Empire Tuned, boost limit raised, MAF deleted
  • Uprated 4 bar Bosch MAP Sensor
- Those combined raise the ECU boost limit much higher than standard meaning I can run much higher boost.
- The image quoted was taken during testing and will not be the final peak boost figure.
  • A special Turbo from Empire - I cant say much more than that at the moment but it is FAR from stock
  • Allisport full size Intercooler + hoses
  • EGR Blanked - Inlet thoroughly cleaned at the same time
  • CJM Uprated Cast Manifold + Wurth extended manifold stud with 20mm stainless spacers - Helps the manifold "flex" / cope with the high temps
  • 3" Airbox to turbo intake
  • Custom 3" Downpipe - Helps to lower EGTs
  • 2.5" Allisport mid box, Custom 3" rear pipe
  • 3.5" Snorkel & pipe work to the airbox - Modified for maximum flow
  • ITG Air Filter

  • EGT Gauge to keep an eye, before hand it would rarely go above 750 unless I was really pushing hard, say 90mph+ loaded up hill.
  • STACK Coolant gauge - So I can view exactly how hot its getting, unlike the standard gauge.
  • STACK boost gauge - Plumbed into the EGR blank for the most accurate readings and keeping an eye.

As for reliability its done roughly 45k miles at 26psi (previously a Hybrid turbo from CRTurbos), 75 - 100miles a day, every day. Also taken me through France, Spain, Andorra, Wales, Pyrenees to name a few! Never properly let me down.

Long winded but hopefully that answers your question!
 
Very nice you have lots of nice bolt on parts With a hopefully a good map but your internals are still standard Can we do an online free vote of how long the internals on your stock td5 will last , will be interesting
 
I like it when oem engines do far better than forged n knife edge cranks alike can do proves previous care of the engine and a good map (mapper)
 
True. Standard internals mainly because uprated ones dont exist. Few people.have developled some parts but generally found not to be needed. That said there is the AMC head which is a large improvment over standard.

As for servicing it had full history before my ownership and proper maintenance.

I change the oils and filters every 6k.

There are 100s of TD5s running very big power with no issues. AJS Tyres have a 110 supposedly pushing 250bhp+ but i am dubious. Either way still reliable under race conditions!
 
So I've done about 300 miles now, mixed motorway and country lanes with the new turbo and its phenomenal. Just instant torque all the time its quite ridiculous.

Pulls hard right through to the limiter, there is no drop off in power. So much so Gareth took the popcorn limiter off as it just pulls so hard. :D but itll be back in the future

EGTs havnt gone above 500, even pushing 90 up hill. Normally sitting at 400 - 450ish.
Turbo spool is ridiculous. Almost instantaneous from around 10psi to 28psi. Zero lag.
Induction noise is intense :p Sounds like Darth Vader is my passenger :D:p
I can say its water cooled as well which is a nice feature. Plumbed into the heater lines with a T-piece.
Also has an M14 thread to accept a variety of EGT gauges, mines 1/8NPT so fitted a small adaptor.

Still needs a little fine tuning as its a little unrefined at the moment, but its still under development with Empire so it will only get better :D

So far on the road its just amazing. I can't believe a TD5 could have such instant torque and power, so pleased.

Weve been careful to keep the fuelling & boost pressure at a reasonable level to keep it reliable - It is my daily driver after all and must remain reliable. However there is scope to push it much further if I want however that would likely require the fancy HD head studs which are like hens teeth.

Got a few bits left to do as my air intake is a bit of a mess, need to remake the airbox to turbo pipe to suit the new turbo position.

Unplanned plus side. Oil changes are easier, huge access to the filters
