May be is because of PSM, as the 10mm outlet goes to the passenger side, to the PSM pump.
Yes, the PSM Boxsters use a 12/10 MC. It's the non PSM cars that have 12/12

Hi John,

I would like to see a picture. The ABS unit is just not in the budget at this point... Sounds like you have a very good setup there.

Are you running 18" rims with those rotors?

Thanks

Ray

Thats correct Ray. 18x10 fronts and 18x13 rears. I will get you a picture of the pressure transducer on Sunday when I return.

Yes, please! If you can also include the MoTeC details, that would be great

Here is the brake pressure transducer set up I'm running. This is a very clean way of doing it as it avoids any flexible brake lines. This is how Porsche Motorsport did it on their race cars.

It consists of:

1x Motec 2000psi pressure transducer
1x EPDM O-ring (withstands brake fluid)
1x Male 10 x 1.0mm Metric convex seat to 3AN adapter
1x OEM brake line banjo fitting (914.355.531.00)
2x OEM copper crush washers (904.355.902.00)
1x OEM Porsche Motorsport 12mm banjo bolt (993.355.517.80) - * No longer available

The PM banjo bolt is unfortunately no longer available so I had several of these manufactured based on exact measurements I took off of the original part. Essentially it is an exact replica of the PM part machined out of stainless steel. I do have a few extras of these if you decide to go this route.

Hope this helps...

Hey Steve, how goes it my friend? When they were still available from PM a few years back they were 78 Euro, so roughly $95. That's what I'll take for one of the few that I have.

Hey Scott. I was at the shop and took a few pics of the Motec brake pressure sensor installation. I'm shipping the banjo bolt out to you tomorrow. Cheers...
