Engine/Transmission (1998.5 - 2002) Diesel Dynamics Jammer Injectors

[cumminsgetme]

Here is some info on DD's new Jammer injectors. I installed them about 3 weeks ago along with a UFM, then dyno'd the following week. The truck dyno'd 356. 7HP with injectors, DTT trans, and Relentless Diesel fuel lines (UFM was turned off). Great nubers for a truck with stock turbo and stock exhaust. With the box turned off there is next to no smoke. From a dead stop with no boost there's a very light puff of smoke but quickly turns to clean tail pipe. Throttle response is great..... a very linear power band.



Since then I've put on an HX40/16 and 4" exhaust. There is slightly more smoke from a dead stop due to more lag but again quickly clears up to clean tail pipe. Pulling a 16' trailer with 1000lbs egt's were 1200 degrees (pre turbo,box off). That's in 4th with foot on the floor at ~90mph.



With the box on, HX40 and exhaust the truck went 495. 6HP

Are they extrude honed or EDM injectors? What hp rating are they?

 

[JR2]

I belive the Jammers are EDM's. Maybe Keith will see this and give us some info. I checkDD's website weekly looking for new info.

 

[KLockliear]

They are new nozzles completely. When I hear "EDM", I think of what others have done... EDM more holes in an existing nozzle. Ours were built from scratch with 8 holes. Depending on the power level, the higher HP level injectors are also still EH'd.

Keith...



You guys need to update your site.

 

[KLockliear]

No info on them yet. Still waiting for the "official release".



They are available by special request, but we are still selling the original ones for now.

Hey Keith, these wouldn't be similar to Russin's injectors?

 

[KLockliear]

I would hope not - or someone owes us some money. Lawrence designed these from scratch and contracted to have them built specifically for us.

[Big P]

What's the claim to fame with these injectors? Better atomization and flow with less smoke and egt with the new tip design? Just wanting to get some more options for upgrades.

I just changed my 125 HP EH'T injectors for Mach 3 EDMS and they feel like I added 50 more HP to my truck. Way smoother to.

When will these be released???

 

[Rman]

I was under the impression that EDM style injectors start with a blank stock and go from there. The extrude honed take existing bosch injectors and "bore" out the hoels to make them bigger. I know Don M's injectors are the reults of tons of research and testing to find which patterns turn out the best.



My brother in law has stage 3 jammers from DD... they're definitely a kick in the pants. I like em!

 

[KLockliear]

They are out now by special order. You have to ask for them.
