This thread, for all the trash in it, did one big thing, which I think the readers should be more aware of (which is a far bigger factor than than the difference between "SAE" and "STD"' results) is the extent that people will go in order to get "Hero results", instead of realistic results.

My results are completely realistic.
Greg -

Having waded through at least 40 pages to this point, I'd like to make an observation, I think it's what you and Ken owe me at the very least, because I'd also like to say it was tedious and occasionally painful. Unpleasant. An experience I'd rather not repeat.

But I'm an S3 owner, have been since 1986. Yep, one of those rare early adopters. I'm not at all unhappy with my choice and the car has served me better than I ever expected for over 30 years. It's a good car. Maybe a great car.

What you're complaining about with your frequent rebukes of criticism is what I've been trained to recognize as the scientific method; by daring to use it (as you obviously have) you invite skepticism. It goes with the territory. The scientific method is inherently participatory; you can't avoid that. Your hypothesis, theories of operation, and results will all be questioned by your peers. That's the job of any scientist involved in the sort of research you've chosen to pursue. You shouldn't take it personally, as you've unfortunately done on a few occasions. If it turns out to be personal, it really doesn't matter, as long as the critique has a valid foundation. We all learn from these experiences, even the ones that might be considered "proprietary". There's really no way to plug the information leak, worst case someone will buy your design and reverse engineer it, call it their own and thumb their nose at you. It just can't be helped.

Both you and Ken are doing valuable work. Stay focused on your goals; they're admirable. You seem to be doing well. Be satisfied with the fruits of your labor and welcome informed critique, you will profit from it and it costs nothing more than a little pride?

Sincere thanks for your service. Live long, and prosper.

PS: I'm reading all of this again after 4 years because I just bought a complete set of your fuel lines, along with a 1988 S4 FPR and that Bosch intake sensor John played with, along with Ken's S300 fuel map. I believe in all of you to the tune of some significant change. I'm not just another looky-loo. Really.

Regards,

You know Tex? On a thread like this one, that question is way over the top Not at all unlike pouring gas on a fire.

But the answer is simple; Mobile 1 10/40. that was a joke everyone. A joke. No need to vent. Calm down. A joke.

NO YOU FOOL!

It's all in the balloon valves! Haven't you been paying attention! Muffler bearings are Old School, no one even uses them anymore! It's all balloon valves now.

Sheesh. What? Were you born in a barn?

Here's the pictures:-
I think there was some interest in the other Bosch temp sensor some are using as a replacement for the one in the airbox.....bumpity bump.
