Another rusty ugly budget drag truck

I purchased the 52 on here or cummins forum set up for a second gen. It has a vband outlet the bolts up to stock second gen piping and the downpipe flange was turned down to accept hx40 downpipe.

When I got under the truck today I pulled down in the hard line I to the aux cooler with the quick connect and it was already out. So that's the cause of the leak. I installed a pair if 1/4npt to 1/2barb fittings in trans and used -8pushlock hose to run to front cooler. I ditched the aux cooler and temp sensor. I also installed a new filter and was unable to adjust the bands because my tq wrench starts at 10ft lbs.

12qts of dex3 later it was full and I took it for a spin. So far so good. Can't test the shifts under load because wheel spin. If I rev out 3rd to 3500 and throw od it hooks and shifts correctly. I plan on pressure cleaning the undercarriage tomorrow and doing some more driving around and check for leaks. I would like to do a pass in od to check peak boost also since I slid the afc back. I thought about throwing the slicks on and Making some test passes but I don't want to kill the trans without a decent timeslip. When the trans does let go I am going to park it for a bit since I have spent a lot recently with the hg and now the trans leak.

Have you driven the hx52 on the street much? How does it run with the 5x016 injectors?

I have no experience tuning a 12v other than this truck. I put a 160gov spring into the afc and had to trim a coil to get it to full fuel at about 58psi of boost. Down low the spring doesn't have tension till about 10psi so this is noticeable on the street. I have to accelerate slow to avoid pissing other drivers off. And when this acceleration I can barely pull out in front of traffic in time when turning onto a busy road. I drive slow normally too and I still find it difficult to keep smoke low. Also I stay out of o.d. Unless I'm going 55+ on the highway because it's smokier in o.d. I may try an aftermarket afc spring that has tension down low because now I essentially have no afc below 10psi.

You need a spring that will control fuel from 0 to 15 psi, that's where most of your driving is. A long spring with smaller diameter wire so you don't get coil bind.

New best!

Congrats that's getting it!!!

Had a blast last night at pbir trucks yeah. I would like to make it to sgmp for nhrda. Next mods are an electric lift pump and some caltracs.
First pass with bugs worked out.

New best

Any modification to the front end? I see you removed a few leafs just wondering if you did anything up front!

Not yet, I may cut a coil and see how it does. I would also like to do longer shackles in the rear to get it about 1" lower.

I know on cars the remove the sway bar for the back end to plant better. I was wondering about that maybe?

Do not cut a coil! It will lessen the front end travel and lessen the upward force of the front end

this; for those who don't know, removing coils increases spring rate (less material left to deflect)

So I need to spend some money on 1500 v6 coils.

I would think they would be soft and spongy. I know the 1500 springs in my 1/2 ton were.

how would you define soft and spongy... like "works at the track, deal with it on the street"?

Or rides like Uncle Buck's car?

Got v6 springs and it is spongy, haven't ran it at the track yet but front end comes up quick.

seems like a good shock could remedy some of that?

Any info on removing the sway bar?

^I'm actually considering doing this and reporting back.... that ****er is probably the #1 biggest weight drop on the front end of a 2wd without hacking the truck apart

I'm just comparing it to the race cars. I know they ditch them so the back end plants better with the front end having potential of lifting higher.
