I'm completely lost in whatever conversation Dr. Bob and Tuomo are having.

Does it have anything to do with my manifold?

Update: Plenum is now cut apart.

"Housekeeping" tasks and some design changes.

Retesting soon.

Whose driver's license will we be risking with the next round of datalogging?

I spent far too long comparing the ***** to see if it was the same girl before I noticed the tattoo in Rob's picture...

You guys are going to make me turn avatars back on, arent you?

Rob Edwards

Not if you're at work.

I was just speculating about the cross-sectional area of the intake tract and how that impacts the air speed and thereby the torque curve, which then lead to the conversation about "sonic choke" at some mass air flow rates.

That conversation is/was somewhat off topic, but perhaps not as much as some of the later entries.

Rob Edwards

Point well taken, Tuomo.

ptuomov

Was that your wife or your girlfriend temporarily T-Rexing in your avatar, or did you just luck out with a google search?

Rob Edwards

If that was my wife (or my girlfriend) would I be posting on Rennlist right now? Let me answer that- No.


Actually, while I was scanning the new avatar pic, I came across the next figure in the article (928 Forum magazine, Summer 2002)

https://webfiles.uci.edu/redwards/pu...2012-22-12.pdf

Comparison of stock S4 intake runner flow at various valve lifts. Forgive me if this is an Enzo, but I'd forgotten that this data exists. Might be germane to the discussion (?) I assume that the 40 mm Ti refers to titanium 40 mm intake valves (?)

ptuomov

I've had some like that and my experience is that you'll still get bored and start thinking about car stuff.

Do you mean this article?

That is correct. My recollection is that when Threshie installed the 40mm intakes, he discovered that there wasn't room for the stock exhaust valve, so that he actually had to go to 1mm smaller exhaust valve to make room for the larger intake. Don't know if there's truth to that, just my recollection.
