boost actuator and boost bleed valve

[svanh1993]

Hey guys just wondering as I can't find much on the net but when running a 8psi actuator on a td05 16g such has the internal waste gate and you added a boost valve can you add more boost than the 8psi or is the waste gate actuator the limit for boost

 

[VIN18M]

The wastegate will be your starting point, you won't be able to go less than 8psi, but can increase boost above 8psi.

 

[svanh1993]

Thanks mate wasn't sure on how it worked

The boost valve tricks the wastegate to stay shut for longer.

 

[svanh1993]

Okay cheers

The general rule is to run an actuator rated at half of your intended boost level. If you intend to run 30psi then get a 1 bar/14.7psi actuator.

Thanks clutz I'm not planning on going over 16psi so all good then with the 8psi one what dump pipes may be a good option is a screamer legal in qld ? Was thinking a 2.5inch on the impeller and a screamer pipe for the waste gate instead of plumbing back into the exhaust

Id doubt a screamers legal anywhere in au....
apparently they try an ass rape ya if ya have one,

Na..its a fine for first offence...bigger fine the next time.

[svanh1993]

Is that the evo3 one or cause the turbo I'm looking at is a 7cm exhaust

 

[VIN18M]

I'm running one of those on a 20g, so it should be fine for the 16g you're going to use.

 

[svanh1993]

Are you running a 4g93?or63 with that 20g and when does it come on full boost.16g should be on full boost at 3000rpm or would that change with higher compression and lower boost

 

[VIN18M]

4g93 , I think I'm on full boost (25psi) at about 3,500. - but that's running e85.

If you run higher compression and a 16g you will see full boost a lot earlier but will be limited to how much boost you can run.

 

[svanh1993]

I will be running a 8psi actuator and running it on max 15 psi the 16g but I'm going to start on 8psi

Get the MAPerformance screamer...much better quality than the one above.
I have heard of heaps of complaints about that one not having a flat face etc.
I have the MAP one and its quality is awesome.

 

[svanh1993]

Okay best place to get them?

 

[VIN18M]

Are you sure it wasn't the ebay copies that didn't have the flat face?

Mine was perfectly square when I received it and I'd be surprised if it'd warp considering the flange on it is 18mm thick.

They have a lifetime warranty too, so even if you did have an issue they would replace it for you.

 

[evo-gsr]

Punishment and the ebay ones.

 

[evo-gsr]

Lifetime warranty but you would most likely have to cough up for the postage there and back which would be a killer.
Both types were mentioned in the thread I was reading somewhere.
