95' Junker Drag Truck

a bigger "small" turbo to get rid of some back pressure,
a slightly bigger "big" turbo and a real p pump ought to hit it home in a hurry.

sure some more weight can come out too!

So you're thinking maybe a box S363 over an 89mm HT80?

And for the pump, 13mm "Import Plungers/Barrels" or should I try one of those nice Hamilton pump cams with the stock 12mm plunger setup.... it's a tough decision.

In the meantime, I'd really like to custom machine my He351cw for a larger turbine wheel maybe a 64mm wheel from an HX40 application. I might as well bump up the timing, add-in the bigger injectors, and possibly try some full cut delivery valves. Who knows, with those changes, this little 160 pump might be able to push those ET's even lower!

And last but not least, it would be nice to get a larger slick under this truck. Something in the 32-33" height and 12-14" wide range is what I'm looking at right now. Just need to find the right deal!
 
I like the thought of a 13mm more than a 12mm pump. Even at smaller cam lifts you can get a much faster rate. Avoid import barrels and plungers to keep failures down. Although a hamilton pump cam could benefit you even more due to the crappy 160 cam fill time.
Better yet, do both!

And yes, bigger turbine and compressor on the secondary. The s300 stuff is beefier than the holset. And parts are just as plentiful and cheap.

both would be a good option. I'd like to see how long rockentech plungers would last. but then again, when a plunger sticks at full rack and ruins a lot of parts, the saved 700$ would not be worth it.

the hamilton pump cams are cheep, and easy to install.

either way, the results would be cool.

Looks like NHRDA got the event pictures posted up on the their website:

A couple of launch pics, looks like those sidewalls are doing their thing!

Down track looks like it was still wrinkling the sidewalls, amazing how much torque these diesel motors produce!

I think I was looking over to make sure I caught him, he was quick on the tree!

Awesome run!That Blazer you ran is pretty dang fast also.

That Blazer was no slouch, I wonder how much it weighs? It might actually be heavier than my race truck meaning he's making 800+ HP!!!
Sleeper for sure!

Not trying to get off the subject of your truck.Was the Blazer a Cummins or Duramax?

Someone posted on here it's a blazer body on a 95 dodge chassis that's been cut down. Very little or no spray which is amazingly clean running for a fast 12v w/o nitrous.

JDT is such a cool project. I enjoy following the thread.
 
How's the trans seem to be holding up now? I see you didn't change anything there, have you thought about running a manual vb?

Hey Will,

Are you still on stock low pressure fueling?
Click to expand...

No, for several years now I've been running a knock-off Holley Black feeding 20 psi into the stock mechanical lift pump. Combined with a modified overflow valve, it makes 80 psi at no load. Then I have a second electric lift pump, Walbro 392 on a separate feed and filter system that feeds the front port on the injection pump. This system bumps pressure over 110 psi at no load and maintains roughly 95 psi at full load.

The transmission is running great! At this point, I love that the tranny automatically shifts at my preset shift points of 3000 rpm 1-2 and 3200 rpm 2-3. It gives me more freedom to focus on steering, racing, maintaining traction, etc.

Is that a line pressure gauge hanging off the dash?

It's not still that single disk converter is it?
Click to expand...
Yes, transmission line pressure 200 psi gauge hanging on a wire from the dash. In the video, can you see how much pressure it's making??? That's top secret!

Pretty sure it's a DPC triple now.

YES, legendary Phil Taylor DPC triple disk converter in the truck!!!

Smart thinking on the filter mask

Thanks, I learned my lesson 3 years ago at the NHRDA desert diesel nationals in Wittman, AZ that a gas mask is necessary on long smokey burnouts!

Wow, nice. So do you only turn on the Walbro when you're going down the track? And there are no issues with going through the stock mechanical pump like it being a limit when you get into it?

And where do you have the filters then?

95 psi at full load sounds fun ha ha, is there more of a risk of making the rack stick at that point?
