Turbo lifespan

(1/17) > >>

gords:
Do turbos generally work until they blow up and/or generally fail? Or do/can they gradually lose effectiveness?

I'm currently looking at options to up the power of my Discovery, but it's probably best to check everything is working efficiently first!?

Is it just a case of connecting a boost guage to check it, or is it more complicated than that?

That's the best place to start, it will give you an indication of the turbo, actuator and lift pump performance.

What's the procedure for testing and what readings would I be looking for?

Anyone got a boost guage handy? :wink:

Jasons got a boost guage

u just plumb it into the inlet manifold.

I would think carefully prior to making any adjustments - the consequences can be expensive.

Yes, don't worry!!

I need to do something as it struggles to reach, let alone maintain, 70mph :shock:

While on holiday (France, Alps) I found that 60 - 70 was impossible to maintain where the roads were not flat (or there was a headwind!). Although, 75 - 80 was better but I could only get to that sort of speed downhill. It managed to maintain it on the flat but would drop to 50 -55 going uphill :(

To/from Wales this weekend was a similar story - pretty much impossible to maintain 70mph. 4 hours at full throttle is not good for fuel consumption ... and it makes my leg ache!!!
