Turbo Spool

[S10EAT]

Hi guys,

My PD150 is taking forever to spool up the turbo recently, normally would come in at around 2000-2100 rpm but at the moment power doesn't kick in until 2500 Rpm??

Any ideas what would cause this?

I've recently gone back to standard lower intercooler pipework incase the increase in diameter to the SFS pipes were causing lag, but it's no different.

Cheers in advance.

sounds like sticky vanes or perhaps a vac leak

I've checked the actuator for movement and it has full movement, not difficult to push by hand at all.

I have just replaced the vac line from the n75 valve to the actuator but no luck.

Only thing I do have that is slightly different is I have a pierburg n75 valve, would this cause lag and power to be delivered further up the range?

I do have the original so I will put this back on to see if it makes any difference but just wanted to know whether anyone has any difficulties with the pierburg n75 for the pd150?

Thanks

the next thing I'd check is to apply a vac to the actuator for pref' with a guage and see if it goes full cycle

Not to worry about this one, it was the map I had on!!!

Back to standard and spooling good again!
