Question? Can i get my turbo accuator wound out a bit

[Leepey74]

Just a quick one,

Can i get my turbo accuator wound out abit more to produce more turbo boost??

Also will it damage the turbo?

Regards

Not sure of the Petrols, but on diesel TDI's you can give it 1.5 turns without a problem.

I have, but remember getting it wrong the 1st time around. You will just get that little extra overboost.

Okay now I need to see the engine layout with a pointer to the correct location & which way to turn...... Mmmmmm

If i was u leave it where it is, Ie factory position on a non chipped car there is nothing to be gained but trouble by altered the waste gate, if u want more power for cheap get an upsolute chip from impossible.:cheers:

I think I've got a VAG COM log of the before and after which I can post if I find it.

But I am tuned rather than chipped.... Not a humble 90bhp.. But closer to 130! So its food for thought

I would not touch the actuator ,it is preset at the factory and on a chipped car can lead to overboost/limp mode problems.Leave it alone and just chip it.:cheers: Andy

can someone explain what exactly winding out the turbo actuator is???

I'm explaining it in a tdi point of view, but the idea is the same for petrols as well.

Basically but winding out the valve, your going to get a bigger initial spike in boost pressure. It takes just an extra bit of time before the actuator closes the vanes on the TDI vnt turbo. On a petrol it would be the wastegate ???.

My understanding is that if you wind the wastegate a bit then it changes how wide the wastegate can pen when set to full open. So if you consider the normal full open position to be 100% then if you wind the wastegate up 10% then the max the wastegate can ever open to would be 90%, meaning you are still getting a little boost.

So, by winding the wastegate you are effectively making it so that the ECU can't throw away all the boost even when it wants to, thereby giving you a litle more.

Personally I would say stay well away from it. Let the tuners do the tuning.

Sort of sounds right for a petrol, but I'm not sure. On the vnt turbos (tdi's) you'll get just a little extra boost before the accuator starts moving the vanes.

I know this is an ancent thread but ive been doing some searching on actuators as this is what my new boost gauge is supposed to connect to, so my question is....Where is the actuator on an 03 ibiza tdi 130pd? Cheers
