95' Junker Drag Truck

That's what I do with paper towel or toilet paper rolls. Great way for a cheap and quick template. Otherwise if you plan on doing angmore tube work buy BendTech. You can design the work and print out a paper overlay to make your notches. Pretty sweet deal.
 
After another full day of fitting pipes and grinding notches, the roll cage is in the truck.

After installing the main hoop behind the seats and installing the overhead halo bar, I went to work fitting the forward pillar bars. Many roll cages have multiple bends on the front bars to fit them around the factory dash, this kit came with a simple single bend and passes through the dash. Probably not the best kit for someone wanting to keep their factory dash in-tact.

Next I cut the tack welds from all (4) outriggers and used jacks to lower the cage so it could be welded in a lowered position where it was easier to access the topside of the joints.

Lowered about 6" for welding access:

Then simply jacked the whole assembly back into place and welded the outriggers to the frame.

Next I added the rear support bars. The minimum allowed angle from vertical is 30*, mine ended up in the 35-40* range since I wanted them to hit on the seam in the frame. Then if I ever back-half this truck, I won't have to move the bars.

This is what the custom notch looked like on the rear bars since I went from the corners of the main hoop down to the frame requiring a compound angle on the notch.

Next I welded-in the door bars, main hoop supports, back seat brace/seat belt bar, and dash bar. The door bars must pass between the shoulder and the elbow when seated in driver's position. The back seat brace must tie into the main hoop and be located within the range of 4" below the shoulders to level with the shoulders.

Subscribed this thread is the reason I joined Compd thanks for all the info definatley want to see the junker hit 9's
 
There are some BIG changes coming to the Junker Drag Truck. I'm trying to exercise enough self control to make them one at a time.

Some excellent sponsors have stepped in and provided some top tier performance parts. Full write-ups will follow and hopefully excellent power increases and track ET's will ensue....

Congrats! I've been wondering when you'd get some sponsors. You've got enough people following it.

What's your new goal? 9's without coilovers? :rockwoot:

Yes, goal is to get it into the 9's! I need to add about 200 HP and maintain or improve on the current 1.65-1.73 60' times and it will solidly be in the 9's.

That's awesome! I'm thinking 2wd SS truck?.........

Yes, the goal is to run in the NHRDA SS class so I've been planning modification in such a way to stay legal for the SS class rules. That 1000# weight advantage the give 2wd over 4x4 trucks has not yet been exploited, it leaves the door wide open for a moderately tuned up 2wd!

Something Bout a Hamilton head and a real injection pump? I am excited!
Click to expand...

Yes, Zach Hamilton has stepped up with some sponsored parts, full write ups, back to back testing, and anecdotal notes will follow. Hamilton supplied one of their high flowing cast heads, it will be interesting to see back to back boost, ET, MPH, and calculated average horsepower differences between home-ported stock head and as-delivered big-valved Hamilton Head.

The 160 pump is completely tapped out due to the lack of refill time on the stock pump cam. Hamilton Cams has sponsored a new V2.5 quick rate pump cam complete with new tappet springs. A pump shop will flow the current 160 pump as-is to see how un-balanced it is and measure total flow, then the new Hamilton pump cam and springs will be installed for a back to back flow bench test with the original 12mm plungers and barrels. Then the pump will be strapped back on the drag truck for before/after track testing/results.

At this point, the He351cw over HT4B setup should be completely tapped out as far as airflow is concerned. A new larger compound turbo setup will be constructed utilizing a modular box stock Borg Warner S363/68/.88 w/external gate over HT80(89mm) (Basically a reverse rotation HX82). The new compound setup will need more RPM to spool and will probably make enough power to push through the triple disk converter. Phil Taylor with Diesel Performance Converters has stepped up and sponsored one of his top of the line quadruple disk converters complete with a looser than stock V-10 stall.

The power upgrades will test the traction limits of the Junker so the battery will be relocated to the rear (aid in traction) complete with NHRA compliant rear-mount electrical kill switch (required for 9.99 or quicker). Other planned upgrades include a rear-mounted fuel cell for both weight reduction and to act as rear biased ballast. New larger slicks and wider wheels have been sourced locally from the bargain bin that is Craigslist so I'll finally have some decent sized slicks out back to try and use everything this motor can produce. And finally, a choke-cable operated home-made air shut-off will be installed to meet the new NHRDA Super Street Class rules for 2015, and act as a secondary safety precaution in case of a run-away pump.

This ^^

I know 2wd can take a ton of suspension tuning to hook but a 2wd seems like a no brainer when you look at the advantages. Less weight and less parts are always nice in racing!
 
That's awesome! It definitely seems like it'd be tough to only toss one thing on at a time ;-)

You need a camera person to get some good videos of you flying down the track.

I spy a go pro mount in a couple pictures :Cheer:
 
I've been ready to see those bigger compounds strapped on to that thing for a long time!

Since you have a fancy new external gate I think a little nitrous should be thrown in the mix ;)
 
Ive spent some time reading this thread its the best yet for sure its so detailed. Im glad you got sponsored you put more work onto your thread then i have my truck cant wait to see this thing in the nines.
