Don M flux 2 injectors
 

All right my new motor is almost wrapped up and had to pick the injectors and since that is the number one problem with these trucks I decided to go with Don M because I have never heard anything bad about his injectors. But I was wondering with all the cracked injectors and leaky ones has there ever been any problems with the Don M flux 2 100hp injector for the common rail. Also how many people are running them and what should I watch out for. I cannot afford anthor rebuild on this motor as they are not cheap. I went ahead and went with the Don m Flux 2 injectors, pro street puller 66, cam, Don M valve springs, arb head studs, airdog fuel system, with edge juice and maybe the bullydog if I need it to pull, and the haisley dual disc street puller clutch. I think I should have a pretty wicked setup then when I get the money and stage 2 cp3.

The Flux 2's I just installed were one of the best single mods to date. They knocked almost .7 off my 1/4 mile time, helped with spool-up, and burn really clean (zero smoke at WOT). :cool:

That would be because you have TWO turbos. Mine smoke like crazy. Got to get me that 2nd turbo.[coffee]

my flux 3.5 smoke like acoal train if I am too heavy on the throttle but after the silverbullet lights I get a slight gray haze at wot with the pyro at less than 1500

Man I wouldn't think 1.8's would smoke especially with the A3k... what's up with that??

I have to ask because I am looking at 1.8's as my next mod... what HP were they? 80?

does your pump keep up with these? no cut out or anything?
Im thinking of going bigger if I pull mine out again. they for sure seem to help with a big single charger it helps it light up alot better

Don,

Pls see Nathan's e-mail. Time is getting short for me.

Tks,

Pat

How do the flux 2's tow? Anyone pull a load with them in?

You also have TWO turbos, so you have nothing to worry about. The A3k is not a very big turbo and we're talking around 600hp of fueling. Dyno runs have shown that Don's ratings are on the conservative side. I know a truck with a Smarty that the 1.8 showed 110hp on the dyno. We're expecting 90+ out of them on my truck.

I have surging issues with the 1.8s and my A3k. With MPI compounds you won't have to worry about towing with the 2.0s. They should be real nice.

I have towed with my 3.5's and 66 charger and it towed fine. It wasn't heavy but still 10K.

Sloverado I would love to see what the smoke factor & egts look like with your truck towing 10,000 lbs with 3.5 fluxs and a single 66, 10k seems like a decent load to me how far and how long did you pull ?

Does anybody know the ratings on the flux injectors? Ie, what hp to expect out of 2s, 3s, 3.3s, 3.5s, etc?

Sloverado, are you runnin a single pump, or duals?

There was min smoke with Smarty on 1 and Flux 3.5's. I run a singe stage 2 Floor It pump but will be going to twin pumps this month. With the ProStreet 66 on a big hill it would hit 1100-1200 but stayed in at around 800 most of the time. That is the heaviest load I have pulled with thes inj. That was 320 mile trip.

The Flux 1's are 40hp and the 2's are 100hp. Can't really help you with the rest of them though.
