I have gotten a lot done in the last couple weeks.

I got the HX35W mounted and plumbed. It required me to scoop the hood. The hood is from jegs and all I did was cut it to length

I think it looks great.

I also was able to get my turn signals built.

The turn signals act as running, marker lights like the original and then blink when turning.

These lights are from a motor cycle shop on e bay and have a smoked lens. They look super sweet.

Here is Oscar in his natural environment. The diesel is completely unbelievable. The amount of torque and power is awesome.

The fastest I can go with the pedal to the floor and 2500 RPM is 74. Hey that's fine with me Jack.. it isn't a race car.

But with that said. I crushed a newer Cummins dodge pickup for the dirst

Oops my thumb slipped.

I crushed a Cummins dodge pick up all the way through 4 th gear and shifting into 5th. Then I was left in a cloud of dust and embarrassment while coughing soot.

The two pictures above are of the HX and my plumbing.

Here is where I put my gauges. I bought the pod from quadratec. And the gauges are automated phantom 2. Backlit leds.

Damn auto correct autometer gauges not automated.


A problem I ran into after installing the HX was the larger intake pipe. The HX runs a 4 inch intake. The problem was my water neck into the thermostat is in front of the turbo and no stock four inch bend would clear it. So I made this

The finished pipe works great. I cleaned all the welds up and used a little filler to smooth everything. Looks like it belongs there.

Ksilovich,

I am getting 20 - 25 psi. 25psi is the max. My waste gate isn't opening either. My turbo already had a home made waste gate bracket on it. The waste gate points down from the turbo which works great with my setup. I think the homemade bracket is longer than stock therefore holding the waste gate closed. I am running rubber fuel injection hose from the boost pipe to the waste gate and with an air compressor it took 40 psi to open the waste gate. I tried to find the heavy duty plastic tubing for the waste gate and the only place I found it, they wouldn't sell it to me!

I am still really new to the diesel world. is 20-25 psi good. It is a challenge to get any boost in first and second because I run out of gear and the governor starts killing the fuel. I tuned my injection pump and that helped a lot. I have a boost elbow installed by it is completely open right now. Like I said the waste gate is NOT actuating at the moment.

I only have off road driving on mine right now and that is mostly in second gear, but I can reach about 30psi on mine. I have my waste-gate welded shut. I think 30psi (at the intake after the intercooler) is a good top end for the 4bt's.
IMO unless your going all out on the engine, there is no real reason for the waste-gate.

Oh okay. Well maybe I won't spend the money to change the Wastegate. Thanks for the info.. I also used your advice on the turn signals and they work great.

Great build by the way. I really like your suspension setup..

Thought Id post a little update after putting 100 road miles on. I am not sure if you have a different gov spring installed. If you don't I would recommend the 3200 rpm. With that installed, and my pump turned up one turn, and my new fuel pin. I am able to get about 10lbs in first. (but my first is a granny gear.) 2nd = 25ish, and 3rd = 35lbs.

Thanks on the complement. I am glad to hear that you found that useful for your lights.
