What is everyone using for a drive pressure sensor? Do you have a sensor that has held up for a long time? What are you doing to minimize pulsing?

A normal boost gauge or a pressure transducer works fine. You want to use some sort of a cooling coil made of copper tube or brake line. I always put the port in the turbine inlet flange on the pedistal. If you put it too close to the exhaust ports you will probably have issues with a jumpy needle on the gauge.
I just used a isspro 100 psi boost gauge and sensor. I mounted it on an 8" peice of stainless brake line that goes straight up from my header. It's worked great for 3 years and has seen some extreme heat. Also doesn't seem to flutter to bad. I tried using a coil of copper but it was always in the way so I tried the brake line.
I put mine right in the passenger manifold used 5/16 brake line coiled it like 6 times and then headed up ran along the top above the turboto where the wires go thru the firewall then ran 1/8 copper line from there thru the firewall to a 100# boost gauge.I have to disconect mine after tuning because I get condensation in the line and it ruined 1 gauge so I leave it disconted.some guys put in a dip catch in lne so the fluid catches there and the presure can go right thru.
Im not real sure but I think if you go from large tubing down to 1/8 after running a good distance I think it helps with the flutering I have no issues with fluttering myself either but I have seen those who have.
Here's the filter setup I had on my cummins. We made the same thing for my buddy's Dmax too. It's the thing that looks like a pipe bomb hanging off the dipstick tube. Just put in a brown brillow pad and it catches most of the soot. When it gets full, change the packing and you're good to go.
you guys that put them in the header tim and dave did you just use the pre drilled bungs rick has in the headers? garrick had one in the truck everything is there i just need to hook it up but he had different up pipes before with bungs in them for the gauge
if you use a coil, I agree with Dave it seems to always be in the way. I would do a longer piece of brake line and run it somewhere out of the way.
It can be in the way, but it's so malleable, who cares. Mine is threaded into the #7 cyl bung on my headers. Each cyl has a bung on them bad boys:thumb:
Mines run the same way but I have a needle valve plumbed in and pinched way back to minimize pulsation, then I just shut it off when I dont need it for tuning.
I used an isspro "exhaust back pressure" 0-100# gauge. It is actually made for drive pressure. Used 3' of copper tubing coiled up out by the #8 cylinder and doesn't flutter at all and been on for about 45,000 miles without a single issue
