Borg Warner EFR Series Turbo's V 2.0

[Borci88]

So a further update for this one.

Turbosmart were very gracious and took one look at the wastegate and said this is our original version, we will just replace the entire thing and send it back to you. So I fitted the new wastegate with its new revisions and took it around the block on spring pressure (9 psi spring). Appears the minimum it will do is about 16psi. Keep in mind this is only 2nd and 3rd gear pulls. I think the issue is fixed compared to what it was doing before however I'm happy to provide more logs if anyone thinks theres more to the story to uncover

I think this is still wrong. There is something crappy with wastegate priority (or the f**king absence of it) if you can't get below nearly double the base spring pressure.

But if you're happy with what you've got, upload skid vids now.

Admittedly in that screenshot its doing about 13psi but later on in the log theres definitely spikes to 16. What is missing though is the massive peak, then a big drop and then a recovery. While it does go a little higher than I would like on base pressure, I think it's reasonably safe to assume that boost control via the mac valve should be a lot easier to control from here on out.

I wasn't game to hook up the mac valve today as it's very wet and it's on the verge of fighting traction as it is.
