Iam looking into getting some bigger injectors for my 01. my local diesel shop is saying that anything over 100hp sticks will cause idle problems and start-up problems. anybody running larger injectors that can give me some input?

 

Fill out your signature so we know more info on your truck. Bigger injectors will make your truck idle different over stock injectors. Just make sure you get a name brand injector and you will be fine. And make sure your have a good fuel pump to make sure your not starving your VP44 such as a FASS.

DDP
DonM
Industrial Injection
Edge Jammer

Just to name a few

I am running some pretty big sticks. Idles just like stock.

I'm running a set of Don's 8+++'s with no problems with idle or start up!

As Said, Start with a fuel pump and we'll all try to lead you the right dirrection, I cant help the fact im very partial to Dons injectors!

 

I got big B&D injectors and it is just like stock till i smash the go pedal.

 

i am running mach 4`s and would not hesitate on the bigger injectors....truck runs smoother and is quieter to boot...did i mention power

me and my buddie both have industrial injection 370 stage 2 injectors in my 94 12v and his 95 12v and there is no differnce in how it starts just on ours you have to push the pedal ever so slightly just to get them to fire

 

the only time i have heard of the idle lopeing is from the hrvp-44 pumps. as for hard starts. thats news to me!

 

I think I'd look into a different diesel shop to do any of my work. One that seems to know what their doing

 

We just put some Fireball 200's in a truck with a HTT 64/14. Idles like stock and has very low idle smoke.

The bottom line is that the truck requires 'X' amount of fuel to idle or cruise or make a given amount of power. The injector does not play a huge role under these conditions with regards of quantity of fuel consumed to do a specific job.

Some of the old DD injectors were known to have some driveabilty issues on the bottom end. It's my thought that the spray angles were compromised due to excessive honing. This is why we started seeing more mileage with EDMs. Better spray angles and precise fuel metering out of each hole.
