Injectors for towing

[Don-T]

Does anyone have a suggestion for a set of injectors that can be used for towing with an aftermarket intake and exhaust? The combined weight will be about 14K. I will be all over the country (plenty of hills and elevation changes). I have a Banks box and the EGT only runs about 1000 deg max empty, so I am thinking about a set of injectors and turn the box down for towing and back up some for running empty.

Is that pre or post turbo?

 

[Don-T]

That is the pre turbo temp. It was at 100 mph after running WOT from 40 mph.

I can see higher temp than that on my stock SO with an intake and exhaust. What kind of temps do you see cruising?

Those temps sound very low. Is that a 235/250/305hp?

 

[Don-T]

The cruising temps at 65 - 70 mph are around 600 deg. It is a 305 / 555.

 

[KLockliear]

Very odd. Our 305/555 would make almost 1400*F pre turbo STOCK, pulling a 5er.

Sure sounds low. Our 2nd generation HO with an HX35W-12 turbo would hit 1300 degF pre-turbo towing our 13,500 lb 5th wheel when the truck was stock.

I have a totally stock So 235 HP California truck my wife drives as a daily driver. I can get it to 1250* pulling my 10000 lb horse trailer. On my bombed truck I found that you can control EGT's very easily with a light foot and some speed going up hill. I have run DD2's and 3's and the 3's are at least 200* hotter pre turbo. I am sure a DD Jammer Turbo would make it a little cooler but I would recommend the 2's.

I seen 1300 on my truck, stock, empty, up hill standing on it

Ummm... the question was injectors -- right?



... but do double check that temp!



Something to consider; with the timing and pulse adjustments of a box like the PowerMaxCR (there's others on the market now; that's just the one I have experience with) you can make more power then you could ever safely use -- no injectors required. I run mine on 3/3 (have never had it higher; goes to 9/9); pulling 10000lbs I have enough throttle to punch it; get a kick in the pants; and top hills at 90+ to my hearts content. So it stays at 3/3! When I get insane and have several grand laying around with nothing else to spend it on I'll be getting twin turbos beefing up the head and..... ooops; tangent.



Haven't heard anyone state this yet... so I'll stick my neck out:



I don't think I'd swap injectors unless I was reaching for insane horsepower -- with these boxes there just isn't a need. If you can avoid the temptation to turn it past 3/3 (all stock) or with upgrades maybe 4/4 (possibly 5/5) with intake - exhaust - and a bigger clutch; then a good box with timing and pulse will be plenty and you don't have to mess with engine internals. JMO!

I think the injectors are about the smoothest feeling I have had yet on the power. With my truck, if I didn't tow, I would leave in the stage 3 injectors and run around all the time with 100 HP extra. It comes on so smooth from the bottem and all the way through the top. I know for a fact that the boxes do not come on at 900 rpm's and pull to 3400 rpm's.

I talked to Rod @ Wildcat Diesel, he is getting ready to start testing on the new EDM injectors, if you can wait these will be the best for your money. I will be changing myself.

 

[Don-T]

Greg,

That is exactly why I am thinking about changing injectors. I want more bottom end and good power and reasonable EGT for towing when I have the Banks box turned down. Then I can have more power for running empty by turning the box up.

 

[Greg Boardman-RIP]

I would suggest again to stick with the DDII's or and 80 HP EDM
