Post: RE: Performance drop off

I'm starting to wonder about the accuracy of some of your boost gauges, you're not using those £20 ones from halfords are you lol?

Post: RE: Performance drop off

TD04's are much happier at around 23-24psi (you'll have to double check the compressor map yourself if you can be bothered to be 100% sure) but that should put you somewhere in one of the efficiency i...

I bet you're barely making any more power at 32 than you are at 22.

Running the turbo at 32psi is completely stupid, it is way out of it's efficiency range, try turning it down by about 10 psi and your inlet temps will drop. A FMIC will help, but you really need to...

Post: RE: Maximum safe boost on 2.1 TD on std. turbo?

Find a compressor map for your turbo and learn how to use compressor maps if you don't already know, then you'll be able to work out how much boost to run. A GT15 at 30 psi for example is ridiculou...

From what I've seen, these TD04's go for around £80-120 and a GT2052S goes for £200+ although you see the occasional one at £150+ but the majority are well above £200. I know it's not a huge amount o...

Usually happens when the actuator spring becomes too weak to hold the wastegate shut, and it starts to open before the set amount of boost. This means it takes longer to get on full boost because ins...
