where are you logging pressure from?

same location you are. I want to get some stock temps and pressures and then compare how our total solution compares

Awesome. I'll test the sandwich plate before then. I came home from work and crashed tonight so I accomplished nothing

@Dave-ROR, mind sharing which gauges you have installed?

Defi Advance CR oil pressure and oil temp, although oil temp isn't in the oil yet. Will buy the adapter tomorrow and install that this weekend if I don't have to drive up to NC.

Where do you have the gauges mounted?

Dave-ROR · 02-12-2013, 01:14 AM

A pillar. My most hated location. I'll post pics tomorrow.

Why didn't you go with Prime Motoring solution, two in the dash?

From my seating position I can't see those locations. Gauges would be 50%+ blocked

Dave-ROR · 02-12-2013, 11:05 AM

Oh also.. I'm hoping to not take a nap after work tonight and hopefully will do the following testing:

Tonight: Install the gauge sender sandwich plate after the oil cooler sandwich plate, install oil pressure there (and temp, or I may just move temp over to the location the pressure is currently read from). If I don't put the temp in the current spot in the block I'll reinstall the OEM plug there.

Tomorrow night: Move the gauge sender sandwich plate between the spacer and oil cooler sandwich plate if possible (lines are exact length more or less but hopefully they'll move up 3/4"), otherwise, remove oil cooler sandwich plate and drain the cooler or loop the lines.

Possibly Friday/weekend, bypass cooler and test pressure sender in both locations again, although I suspect the tests above (plus original/current config) will show the same data as this test.

Dude it's killing me. In that gauge thread I posted some options I'd prefer but no one has made them yet. I *HATE* a pillar pods. I will say if you want an A-Pillar pod the MSA one is nice since it's based on an OEM unit.

I'm waiting for a better solution though.

No.

It is about resistance to flow over distance. Get a 2 foot long drinking straw and try to breath through it. Then cut that straw to 2 inches long and try to breath through it.

You want bigger diameter lines the longer the distance. The pressure drop over the length of the lines will be less.

I have -12 on my vintage race car, but for these cars I would think -10 is enough.
