injectors

[Archive]

Guys,

Big Don here. it's been a while since I posted. Been playin' with the truck some since the head cracking episode. Runs good, but when i put the new head on and the 7mm injectors it only makes @ 21 psi boost max. I used to get @28psi. I got the cummins suggested injectors for this engine. Wha t would wake this thing up?? I am afraid to just crank the pump with these injectors for fear of it junking out on me. I hear about the Teds J. injectors. I like the sound of the 12 cm housing. I hear talk of one getting hot, but my 99 has a 12cm housing (I think??) it still has the original turbo, but 275 rv injectors and VA box. The 89 has the banks 14cm wastegated housing. I'd like more performance please.

Hi Big Don.

You probably need to change to JRE or PW injectors. I was at 21/22 psi (wastegate disabled) with the Banks 14 cm turbo and fuel pump setings turned up. With the new injectors, fuel turned down and the wastegate disconnected I can get 27 psi. A 12 cm2 housing would make even more.

About getting hot, a couple of days ago I ran 17-21 psi boost while driving with cruise set at 70 mph (2500 rpm) near Indio, CA late in the day with air temp at 105F. I was against a 25-40 mph wind and upgrade. EGT was 700-750, post turbo but coolant temp got to 215F (guage needle half way between the third and fourth divisions of the temp gauage's normal range) and then it climbed no further. The cruise was able to keep the truck at 68-70 all the way up and as soon as the grade leveled out coolant temp dropped fast.

Before the injectors, under these same conditons, the cruise disengaged because of the speed drop and with the pedal the floor I could do 55 mph in fifth.

When I am in the mountains the EGT will climb to 750F fast just using part throttle up a moderate grade. The altitude and boost really make the difference in EGT, ambient air temp does not seem to be an important factor. For engine cooling ambient is important.

The crossflow radiator in the '93's does work. A friend's stock '91 could not be run long at full power up steep grades in hot weather.

Hey Big Don!

Great to see you back on line! I was just getting into the TDR back when "Super Hot Pre-93" was originated by you and bantered back and forth by "Old School" and others. Equally good to hear that "Ole Blue" is recovering nicely from the new cylinder head!

Things haven't change much here in the First Generation Forum when it comes to injectors, you still go off to visit Ted @JRE for some of his custom injectors put together by his fuel man in the Northeast or call BD for a set of their High Output injectors. Also "Mark93" and others have had great sucesses with the Bosch 215 HP injectors put together by "Power Wagon"!

One thing that has changed in the new year is that "Old School's" immaculated '92 Powerhouse has been sold and has moved to our beautiful state of Tennessee. It's now driven daily by a young, slender 6'0" tall blond female, who on occasion lets me drive it when I've been extremely nice to her or have washed her truck. Matter of fact I have it here at work tonight! Lucky Boy!

The reason I bring this little tid bit up once again is that former "Old School" ride has the 'Big A**' JRE injectors (Old School's title) in it, while Ted installed the BD HO injectors in my '92 while I was in town. All I can add is that the toned down depictions of the performance of the former "Old School" ride are completely true, no embellishing required. I'm not certain if the performance differences reside in subtle differences in the injector pump or if it's in the injectors but there is a performance difference. Ted mentioned that both injectors are almost identical to each other.

I'm also planning on installing a 12cm2 housing on my truck within the next two weeks to see how 'snappy' the 12 really is. "Jsimpson", "HVAC" and others also have similar 12cm2 projects currently being tried. It used to be everyone wanted a 16cm2 on a First Generation, now we might be all running around with 12cm2 housings and no smoke!

I don't believe you can go wrong with which ever injectors you choose from these three sources!... ... ... . Keeno

Keeno was slightly mistaken when he said I was involved in using the 215HP injectors to make power. WE've tried them and they run great, but do not produce lots of power.

The injectors I tried to produce lots more power seem to do the job quite well. Our best estimate is that it raises the horsepower from 160 to about 230 or so, without turning up the pump! In fact, we tend to turn the pump DOWN from stock settings to cut the smoke a bit. It is most essential that your timing be verified - both the pump and the engine stop pin be carefully set, and then the pump installed at 1. 3 - 1. 35 mm.

To answer the question I read above... for 1st gen trucks... the secret to horsepower is injectors, NOT turning up the pump. That VE pump is a nice chunk of machinery, but it isn't reliable at higher fuel settings.

How to get power from a first gen can be summed up in three words: Injectors, Injectors, Injectors!

Power Wagon,
I sit corrected! Sorry for the bogus information regarding the 215HP injectors. I was confused by one of the latest injector postings where the 215's were discussed as replacements.

Mark93,
Shouldn't that be injector, injector, injector, injector, injector, injector? I would hate for Big Don's truck to only run half as good! #ad

I guess (3) plural "injectors" could equal six! 3 x 2's = 6
Yeah! That's the ticket! #ad

Okay guys how about fuel mileage with the injectors. Someone convinvce me on which injectors to buy. This 12 cm housing has me intrigued. I know it will spool up quicker but how about towing?? I have the waste gated 14 cm housing now. How much is the 12?? Someone get one on and let us know. I can tell you guys this; I have ran against my friends 99 psd 6 speed and 3. 73 gears. I blew it off the road. Then he got a 70 hp superchip, I still outrun him, just barely. It kills him that 'ol blue still moves out like she does. Love to keep the PSd's in their place. Like I said earlier mine will run with most mustang GT's unless they've been tweaked. I can always use more power though. I'd like to be able to do a really cool burnout like Piers, but probably never happen with the VE pump. i am ready to get the injectors; tell me which ones to get. Maybe email me so we talk about price and service. I know over fueling the Ve pump can be disasterous.

later
Don

Fuel economy should change little to none unloaded and not pushing it. Push it or tow 12K through the moutains and you're going to burn more fuel. If you can do it in a tall gear (staying in 4th/5th) instead of shifting down, it will probably help, not hurt, or at least not hurt much.

If you have the 14 cm2 housing, I would not change it. There's little to no "improvement" for the money spent. You'd be far better off to spend a few dollars less and get the big-hole injectors. Then, go back and crank your pump down and watch the PSD drivers gape when you blitz 'em on the grades #ad


Feel free to email me, if you wish #ad

Heh... . Good to hear from you again!!
Got some injectors installed a couple of weeks ago and I only get the 21-23# range with boost, but I have the stock turbo.
I have to get some more info on the injectors as they came as the "BD performance" injectors for the '89. What exactly they are, don't know. So far my mileage hasn't suffered at all, 21 MPG. US. , just like before, only no smoke, and another 3# boost.
How is ol Blue anyway???

O. K. KEENO:
Let'em in on the MPG. Let'em in on the power.
Let'em in on the 16, and the 14 housings subtle but sweet differences. (actually can't believe you proud 1st Gen diesel drivers want to go to the 12... Ahh, youth).
XANDERBILT would probably want you to share a little info regarding the truck, and yours, anyway.
Long may you run.

Hey Big Don!

On "Old School's" request I'll reiterate on some of the amazing feats that his '92 Immaculate Powerhouse performs on a daily basis. It's all true, Old School's not blowing smoke but his former ride sure does while getting swiftly down the road!

As mentioned before, I'm not sure where the differences reside but if I was making the injector choice over again I would narrow my search to the JRE customs or the "Power Wagon" injectors. I'll pull a posting up to the top called "The Tale of Two trucks" for some MPG and performance observations.

Maybe you have already seen it? If so, please disregard... ... . Keeno

Hey Old School!

How about letting us in on the 12cm2 housing's interactions with that mini six cylinder called the P7100! Did you see any increased EGT's while pumping more fuel through the JRE injectors utilizing the 12cm2 on your new truck? If you don't have increased EGT's with the massive fuel delivery potential of a P7100, I don't believe our VE pumps would cause a EGT concern.

What are your thoughts?... ... ... . Keeno

Hello KEENO and folks:
For you all true blue 1st gen guys and gals contemplating a 12cm housing:
Yes, you will have a quicker off-idle spool up.
Yes, your EGT will be higher, most likely NOT in the danger zone approaching 1300 deg. ,(as you would guess, due to the less fuel delivery rate and volume vs the P7100)
Your smoke can still be excessive if not tuned to minimize at the pump.
Now as a comparison:
My P7100 with the JRE 3 plate can make some fuel.
The 300 HP injectors can deliver it.
Did the EGT rise on pull up from stock? Yes.
The 4" complete exhaust system helps keep it "sane".
The 12cm housing, while neatly spooling up rapidly, is a contributor, with the fuel available, to the higher EGT.
The P7100, and 'jectors, can deliver copious amounts of smoke, power, and up scale EGTs.
I've backed off the star wheel, the no load screw, and have reduced the smoke to my driving style, and satisfaction. On a nice hard pull, the EGT will dial at 1000/1100. Cruise at 70 brings on 700/750. I plan to test and document more accurately soon. the MPG is at about 20. 5. A Cummins spill port (delivery valve) dial indicator timing kit is arriving soon, and I'm looking forward to some timing advance work. For me? First off - maximize the power and efficiency using the 12cm housing. Then... lets look at the 14cm for less restriction, and then a look at my old friend, the 16cm. Of course, I can hear the groans... 16cm???? sluggish,. . smoke??. . with all that #2 fuel on tap?. . OK let's try that HX40 compressor end.
Anyway. . hope this helps the 1st gen crew.
Regards.

Guys,

I'm still not sure which injectors to buy. I am going to the diesel fest in Terehaute. Any of you hot first genners goin to show them that the old trucks haven't died they just blow more smoke??? I want to see some of you there. Maybe we can run on the drag strip and see who has the hottest first gen truck. Hope yours is hotter than mine so you can give me some tips!! Mine makes the ford boys around here awfully nervous. I get a kick out of taking a 11 year old truck and dusting the lates greates thing in stroke technology. Pisses off the Ford owners to see 'Ol Blue smokin on by them. we'll be drivin up from Tennessee on Friday afternoon. Don't hold it against me, but one of my friends is drivin up in his white 99 ford dually. We just ordered a chip for him so he could have a little fun too.
