injectors
 

I will be upgrading injectors this year.

What injectors do you like and recommend?
I'm not looking to go past 90hp injectors

Hit me up bud....

Ducky Fuel Injection

Luke

I've never heard of ducky fuel injection.
I thought you got out of the vendor business luke?

Ducky fuel injection is Chris's shop he opened after he parted with SDX

Still around bud

Luke

I put BD 60hp in my 03 lb7 my truck runs great.

I would get the turbo's and the decide on injectors ... that way you know what you're gonna need... build up to the injector ... less smoke that way and hope for more mpg too :tu:

i am running 5x14s in my truck with my compounds and like them
i will be switching to 5x16 done by dfi when i get to a point of having the cash

Thanks for all the reply's guys. I've decided to take care of the compound turbo's first to finish off the air flow then do the injectors.
But I'm still open to the compound setups.

need a horsepower goal for injector/ turbo sizing

Need to know what turbos he is planning on using ... He is planning to shoot for big numbers ...

define " big numbers" ... that seems to mean very different power levels from person to person

big numbers to me is 750 plus

I have 90HP injectors. I was... underwhelmed. To be fair, I'm still running a stock turbo- which is most of my problem- BUT. I will be changing the turbo, and I will NOT be working around these injectors when I make that decision.
Injector technology has changed big time in the last few years, and 90HP injectors (if you get good ones) are far better than they used to be. Pop-off, spray pattern and all that jazz. But IMO, they still aren't worth the cost of "upgrading" to them. I know I'm probably in the minority here, but I'd rather use a top quality 150HP injector and tune the pump down if the turbo isn't up to it.

larger you go the heavier the spray and potential worse fuel economy. injector size is 100% corolated to end goal and turbo size. everything can be de tuned or turned up, build something that is BALANCED across the board.

I think trevor (97cummins) is shooting for the 600 mark .... he understands that he needs input and suck before getting there though ... we have done plenty of work on hit truck ...

We actually need to get mine pumped up a bit ... need to fix my leaking HG first of course .... all in time :c:

I'd be a little bit surprised if he can hit 600 with 90HP injectors. Not saying it can't be done, I know it can, it's just not easy without giving up something significant around town. If what you want is a dyno queen though, I'm sure it's doable. Just my 2¢

5x.014's, 145* cone, for turbos mod your stock wastegate and throw a s475/83/1.1 t6 under it. Or if you are tired of that hx 35 my next choice is and he351. If you are willing to spend a bit more on a bottom charger a gt4202 1.15wg is a great choice

Me personally i'm thinking about the S300 ... 62/65/14... S400 66/74/16 ... was recomended to me ... or the aroura 3K with a aroura 4k primary ... $$$$$$$ big issue there ... :s:

I think you mean 3k and 5k the 4k is way too small for a primary ... and your first set you listed will work but you will be wishing at a later date that you had gone with the s475/83/1.1 t6

thats an s300 charger

bd uses that charger in there towing twins it is an s466/83/1.1t6 tho not a 16cm housing

i thought there towing twins were a 57/65 and a 64/71.

No, it's a 66. I have that set. Pretty happy with it too. I have boost all the time. My friend had the 475 and it took longer to spool up. He had an automatic though.

Bd's towing twins are the 57/65/12wg s300 over a s466/83/1.1t6

yeah thats the ones i was thinking of ... i like to tow ... i couldnt remember the exact details .... :humm:

Still think a bigger primary is a better choice

just a question, i've never used one, but why aren't the garrett ball bearing turbos used much? Seems to me that you could run a larger charger and spool about the same speed as a smaller journal bearing charger, but i'm no expert.

$$$$ I think is the main reason and running water lines would be the second.

our garret guy just got back from classes and i also believe a big reason from staying away from them is that the bearings were non servicable. the newer units now are coming with replacable parts which make them much more pleasurable on the wallet when it comes rebuild time.

Um. "water lines"?

i think all ball bearing chargers are oil fed and water cooled.

Sorry, brain fart. For some reason "water" did not translate in my head as "coolant", even after looking at it three times.

LOL... especially the VGT turbo's ... they hate being hot ... :td:

Yes they are I should have said coolant not water, have you seen any of the powermax gt3782r units in person? If you have is the turbine housing bolted on or held on with a v band?

Personally I think that charger would be sweet in a twin set up if money is not an issue, there stage 2 unit with the internal wg is the one I would like

we still havent seen many of them come in the door. i think its still a -fad to come- ive heard good things from a properly spec'd ball bearing but havent had the chance to ride shotty. lol So no i couldnt tell you how they go together. I had the chance at the extravaganza last year to get a good look at borg's new ball bearing line. they are utilizing a different material in the turbine wheels which are much lighter then inconel. something like half. they look sweet and the idea is cool but again i havent seen on on a truck or have any experience with them. i also believe they are ceramic ball bearing

I see, the gamma ti turbine or something like that is what is in the borg efr's have not heard a lot about them really.

On the garrett I have heard good things about trucks running them as a single on mild power trucks (450 ish) but nothing for twins

same here. i was thumbing through an old diesel tech mag earlier and they had a 12 valve compound build with a GT3788R over a GTX4202R, claimed they were worth 1000hp together. it was a decent read. im still however not a big garrett fan. the quality of everything on them is very sub par when compared to a holset or schwitzer turbo. why do you think every turbochargerd truck coming out of the factory doors comes with a garrett? price. cheaper parts makes the big companys more money. most of them we wont even reman, its just cheaper to replace.

volume 5 issue 6

I'll have to see if I can dig it up, only thing is that 3788r has a slightly bigger turbine than the powermax unit exducer is 2mm bigger

says here the 3788 is a 64mm compressor inducer and a 68mm turbine inducer. says nothing about exducer size. the 4202 is a 75mm comp and a 105mm ind turbine
