This might be a stupid question but I couldn't find the answer on ZZP's page or on here. Does the ZFR 6758 have a high boost wastegate canister, or a medium boost canister?

Also side note: did anyone notice the ZFR is "out of stock" on ZZP's website?

 

It should come with the high boost canister

 

One would think so, but everything I've been reading it sounds like the medium boost canister comes on the turbo from Borg Warner and the high boost canister has to be ordered and installed later, but that doesn't mean that's the case for ZZP. Not to mention, even though the medium boost canister is only rated to 19 psi, lots of other forums have been pushing them to 25 psi so even that isn't an indication of which canister it has.

 

I read a while back that ZZP had it on the lower of the canisters and switched to the other and I'm guessing have been selling that way since. Also remember that with out boost solenoid we can bypass to show the wastegate less to open later.I thought the K04 was around 4psi stock and then the electronics did the rest

 

Mine came with high boost. 28 psi

 

Well my question was just answered. I emailed Matt from ZZP just now and he said the ZFRs they've been selling the last couple years have all had the medium boost canister.

 

Mine came with high too. ...hmmm...oh well

 

MAtt has his story wrong man. Unless high boost is 30 plus psi

 

The 19 psi "rating" for the medium boost canister is from Borg Warner, on the Audi forums I was reading they've been able to get it to boost up to 25 psi. Talking with Terminator2, he is convinced that I have the medium boost canister as well.

 

Ya term said I probably have the high boost canister , I boosted to 28 psi right off the hop.

 

What is said canister?

 

The wastegate canister is the silver piece on an internally wastegated turbo that opens the wastgate to bypass the turbine. Aftermarket wastegates can be opened to change the spring but ours has a preset spring pressure. So when they are talking about a 20psi canister it means it has a 20lbs spring in it so when the engine hits 20 psi it will compress this spring to keep the boost roughly at 20psi. We of course can adjust our boost with tuners via the boost solenoid

 

I guess the boost solenoid is basically a ecu controlled boost controller eh, never really though of it lol
