Yeah, I do log IATs because EFI... but also you're entirely right in that the impact for me is pretty low since my usage is also pretty moderate. Rarely even get over 10psi boost!

Nice work.

I need to get off my butt one day and improve my own intake; currently running with just a big cone filter stuck on the turbo inlet side, but it's not ideal as I now have no washer bottl ...

I found an eBay NOS replacement for mine ('81 931) when it went out a couple years ago. But I haven't been enthralled by the pedal since the replacement. Maybe some day I'll get back to it and try ano ...

Cheers!

Yeah, just realized I didn't come back and close the loop on the tune here at this end... the shop absolutely LOVES the car now, since it starts so easily and just behaves itself so nicely, ...

If you're not getting good streams from the ports of the master - then yeah, time to investigate/rebuild/replace the master. But I'll be surprised at this point if that is the outcome.

Yes, if you ...

Sounds as if you should maybe check your wiring to your temp sender - yes, the one on the back of the head, for the gauge.

I would ask for some correction to your terminology; the terms you're usin ...

I will mention, while I have access to the very best and most complex bleeder systems known to man... on ALL our cars, ESPECIALLY the racecars, we strictly rely on the oldest mode of steering wheel sp ...

Presumably, yes.

Have to say, though, I'd generally expect the failure mode of the master would be leaking past the seals such that pressure could be made, but not maintained... which would be mor ...

Yeah, you should absolutely be able to get a stream that'll hit the wheel well out of any corner. Yes, it functions on pressure, but volume and thus flow IS needed, and if you can't generate flow with ...
