HTT wastegate

[Limited]

I am thinking about just taking the wastegate actuator and rod off the turbo, and wiring the wastegate closed. The only reason is to save space/make bolting it back on easier. Is there any reason not to do this? Obviously I can't limit boost with the gate anymore, but excessive drive pressure can no longer force it open either. So am I increasing the risk of blowin the head gasket?

Anyone?

Probably not the best idea unless you take it off and install an external gate.

x2 i would rather fight with the turbo install then change a head gasket

Excessive boost pressures are blowing the wastegate open?

Try one of these.

Well I've been running it for a few days now wired shut. Still only makes 42psi, no blown headgasket yet!

Carfichris-where is that actuator from?

Bullseye sells them for $100.

If all your making is 42, the wastegate is probably still creeping open a little. You need a turnbuckle or a tack weld if you really want to hold the gate closed tight.

Or maybe I don't have enough fuel for more than that? Seems unlikely to me.

Is that a drive pressure actuated gate?

If so, what is the pressure set for?

 

[Limited]

No, boost pressure.

How is the one Chris posted boost actuated? Looks like a rod, and spring?

Oh well yeah that one is drive pressure actuated. But the original actuator on the charger runs off boost (and drive pressure I suppose) just like a HX35.

it is

it's run off of drive pressure

drive pressure does not blow headgaskets

kthxby

KthxBy???? are you drunk posting again?


I believe that high cylinder pressure coupled with high cylinder temps makes head gaskets blow.

you're right... cylinder pressure blows head gaskets... 85psi is NOT high cylinder pressure

im really thinking that you have a leak some where.. htt's turbos are normally set at around 40 psi (mine was at 38) with a little turn of the wastegate you should easily be above that.

Wastegate is wired shut...

Also I checked all boots again, no leaks anywhere.

Sorry didnt see the questions about it. Its not a Bullseye piece. We build them ourselves. Its purely mechanical and adjustable from the mid 20's to locked shut. Its also less than $100.
