Bosch just called me back. The 3312 filter for the S2000 has a bypass spec of 12-15psi.

Yeah, it must be to keep oil from leaking out the center. Man, that would make for such tidy oil changes. Maybe after I get the 2nd oil pressure sensor put in, I'll try one out to see if oil pressure drops at all. If not, then I'm in business. :)

Originally Posted By: Audi Junkie Chunky, considering your climate, 15w-40 HD with an HT/HS of 4.1cP might actually be the ticket. Redline and all is nice, but actually kind of pointless in your app. People typically overspend on oil, even for cars they are extremely fond of. There is...

Wow, got a response from the lab, HTHS testing is $195/sample. :O Good Afternoon: Thank you for your email inquiry on the HTHS Viscosity testing. The cost for testing used oils is $195.00 per sample. I've also included general information on Savant Laboratory and a Test Authorization Form...

Well, I got a lead on one lab that does HTHS testing. I sent an email to find out if they actually do it and how much they charge. I'll keep you guys posted.

Originally Posted By: Audi Junkie Chunky, fwiw, Real-Time Racing uses Redline SAE 40 in their cars. They run that for hours on the track, so there is some food for thought. My guess is that Redline 10w-30 or GC would be a good oil for you....even M1 0w-40. Like I said, I would have no problem...

I haven't read everything in the thread yet, but I will later today. I just spent some time cutting open two filters & taking some notes & measurements. I'm sure you all have seen filters cut open, so that's not new. However, since my interest is in the bypass function, I thought I'd take some...
