Competition All this time i thought EDM's were better...

looks like i was wrong again :-laf

That's wierd, according to Cat the nozzles are quote "worn out" when the orifices are rounded & smooth! BTW, how do you like J. R's lil' 55? I have jammer 4's & an Edge EZ on my '02, thinkin' about giving it a try. Sorry, didn't mean to get off topic on ya'!

Hum..... maybe I should look at that as I only made 848 uncorrected hp with #2 only.

And if you remember, synthetic oil and extended oil drains were the scourge of the industry, till everybody finally got it. Now they found it first and it's just great. Same thing here.



And if I'm correct, all injectors start out EDM's. That's how the holes get in the tips. The rest is just a "cleaning" process.

Nice write up on their injectors and that Garmon's uses them. It is a little outdated as the 760 was done last winter and since surpassed.



Considering not a single Garmon engine runs a custom cam or big custom turbo's, I think 800hp is pretty darn good.

 

[Luke Warmwater]

Hell, I don't know but it seems a little like politics. People are easily sold on purchasing a turd if you just wrap a bow around it. I guess I mean hyperbola is where it's at. I will say I drive a ~600hp truck at 6000' with very little smoke. I found it interesting that at Indy pretty much every truck smoked like a freight train except Gullet's which was running some of Don's sticks and emitted a light haze(and was right up front). I really don't care but given the choice I will take less smoke



Here's some competing technical "facts" to further confuse us neophytes...



EDM Advantages



Is it possible that there are other factors that contributed to a quality injector other than just how the holes are created? Hmmm

 

[rivercat]

hey luke how did you make 600 with a eth pump or did you upgrade to a hrvp is from where

 

[Timbeaux38]

This is fun watching you guys argue :-{} about extrude honed 12v injectors vs 24v EDM's..... Continue on ... ... . :-laf :-laf :-laf :-laf

 

[Luke Warmwater]

ETC and yes this is funny

 

[mhuggler]

Making a hasty retreat. Gittin' skeered!

Mhuggler i love jr's lil' 55 ... seems as though it was made for this setup ...



i've had it for 20k and after installing just forgot about it ...



can tow on level 2



gets warm on 5x5 ... peaks at 1500-1600 then starts coming back down ... then hits 115 mph



that's with a tight auto ... should be a dream with a stick ...



dyno'd 462 with the little hy ...

505/503/493 (third run had the motor/trans temp gauges pegged) with JR's and the hp was still climbing when it hit the govenor ...



hy dyno graph looked like a mountain peak ... 55 was all uphill ...



everyone who saw the graph recommended increasing the govenor on the motor ... i'm happy right where i'm at



hits 10 psi at 1600 then hang on !!!

 

[mhuggler]

Sweet! As soon as I develop the "fortitude" to tap my pump wire, I'll be gettin' tst comp and giving J. R. a call. Thanks!

Depends on what Cat you have. The older 3406's would always run higher HP on old fuel honed injectors. Pull them out and install new ones, and the truck driver would be upset, cause the power goes down. Newer electronic engines don't start well after a few thousand hours of wear. Run ok, but start hard.

I have heard the same thing from a former cummins engineer, the flow patterns are better out of the rounded hole than a nece sharp cut one. Some of the advantage of the EDM is the ability to cut the angle more precisely, this may offset the better flow of the rounded extruded hole injectors. Also by being able to cut your hole at the angle you want, you can precisely target your spray in the piston bowl, hence less smoke. Maybe the key would be to start with a small edm to get the spray angle you want, then extrude hone them for a nice rounded hole.

Were we at the same Indy???



I was 5th, and I wasn't near the front, and Ray was behind me. The truck that won had almost ZERO smoke. Chevys were 2nd and third, and a slightly smoky Dodge was 4th.

wow ...



so are they running the stock cams?



and what kind of turbos?



just great big stock ones? HX-55 or 60 ...



would help if you needed parts, just go to any cummins dealer and pick up another ...

 

[Turbo Thom]

Around here there are turbo suppliers. And David's right on. These truck have the same stuff in um we all can get from most any turbo supplier or Cummins shop. The trick is how they're put together and where the cam is time.



And another thing I find amusing, is I read a good bit wherre folks say " I will never set my timing past 16*". Jeff said in Houston last year he had his set at 45 degrees. If it works for him, why not you? A lot of you, I think, are listening to the wrong people.

After all the hoopla in the article about how Garmin extrude hones his injectors then this paragraph:



"Darren Morrison, running a Garmon engine in his four-wheel-drive slick-tired Dodge Ram 2500 pickup, won first place honors and set a new DHRA record of 10. 77 seconds for the quarter mile. He outpaced all the higher-powered nitrous-assisted trucks – running EDM-enlarged injectors – by more than half a second". <--- 2nd paragraph from the end.



That's like a kick in the sack, when an EDM equipped truck sets a DHRA record of 10. 77 and not even running Garmins injectors... ... ... .

[Turbo Thom]

Curtis... ... ... ..... I have no idea what article you refer to, but I know for a fact what injectors Darren runs in his truck. There was a set sent to Jeff to try and see "how much better they were than honed". They were put in street trucks and installed in Darrens truck on the dyno. I won't say what Jeff said cause Steve would throw me off the site, but the first letter is f those things, and it just goes on from there.



I know for a fact what injectors Darren runs in his truck and the EDMs ain't it. The injectors are honed and Jeff sets to pressure in his shop. I don't think Darren has ever run the EDMs on the track , ever. They were tried on the dyno, but nobody runs them now. Not even in a street truck.



So whatever the article says, it just is so as, to the EDMs.

Haha Gene I was there Sat and he blew your doors off. Your truck smoked like a freight train and his blew air as fresh as daisies.

PS If you can see through the smoke that Gene's truck is polluting the environment with, does anyone know who's truck that is on the lower left of this picture with dual stacks centered in the bed? That was a sweet looking truck... would like to talk to him. Here's another one.

PS2 this dude still owes me two x-large tee shirts for like the last 6 months lol!

PS3 finally I don't know what this has to do with EDMs but I sure do remember it.
