Let’s have some fun measuring boost back pressure under different scenarios. Step 1, install pressure sensor: 1/4” OD copper tubing, compression fittings, weld bung, 100psi sensor wired and calibrated in TunerStudio.

Heads up. Holdener is going to power-adder (including turbo) a factory 5.9 Magnum to death for our viewing pleasure. Should be enjoyable and educational. Stay tuned to his YouTube channel. https://youtube.com/channel/UC8uf_zVTV63l1-uRSx6XbnQ

Since my current build has diverged so far from my original thread, I'm going to start a new one to help me keep better track of my progress/setbacks. For background on my previous 5.9/Turbo build, see here. TL;DR - stock bottom end 5.9, EQ OTS heads, Fitech, E85 ran a best of 6.90/105MPH in the...

I recently bought an EBay 7875 and wanted to share some dimensions/weight differences with the GT45. GT45= 34lbs 7875= 21lbs This 7875 has .96 A/R on the exhaust, much smaller than the GT45 which is 1.10 I believe.

I've been piston shopping for my next 5.9 Magnum turbo build and have found a few forged flat tops with basically the same specs across many brands; ICON, JE, Wiseco. The Wisecos seem to be the best priced (as low as $409 w/ rings). I realize they aren't necessarily a turbo piston and will put...

There is a small block mopar underneath all of that beautiful shiny work and it makes 1000+ HP!

FYI - guy on Facebook is building really nice looking BB Abody turbo headers.

Saw a lot of really cool cars at the Don Garlits museum but this one really caught my eye.

What spark plug would you guys recommend? I've read a few threads on the turbo forums and YB. Lots of folks recommend NGK and a non-projecting tip in a heat range between 7-10, 10 being the coldest. Anybody have a part # they've had good luck with? Mine is an iron headed 5.9 magnum, stock...

I'm getting close to buttoning up my turbo conversion and thought I'd share some pics on my progress. Car is a 65 Valiant with a stock bottom end 5.9 Magnum and EQ heads. In it's current trim it runs the equivalent of low 12s, in the 1/8 mile. I'm hopping to make it more streetable and dip down...

I'm building a single turbo setup for my 5.9 build and am exploring options for timing control. I know most folks use the MSD 6530 unit but are there cheaper alternatives? My build will be an E85 blow thru, non intercooler and I don't intend on going past 8-10psi. I currently run one of the HEI...

For you guys with the Ebay GT45s, where are you sourcing the Vband clamp/flange combo for the exhaust side? Mine has the 3.25" ID on the outlet and 4" total OD on the flange with a groove that looks like can accept one side of the clamp, negating the need to weld a flange to the outlet. I want...
