EDM's/Custom Injectors and Turbo's/Twins

[Underpsi]

What size have you had made and how do they work? Idle Haze? Power? Efficiency?

For a long while now I've been trying to figure out the best injector to go with. I am eventually gonna have twin turbo's and I only want to have to buy one last set of injectors. What size injector could I order that will be driveable on the street and not be a bottle neck for fuel supply for over 600hp? Im not worried about emissions or fuel economy as my truck is just a street driven toy. When the time comes It will probably a set of twins with an S300 series top turbo and ??? as the secondary still don't know whats best for either. Been thinking of going with a 64/71 with a 14 gated housing and running it as a single for awhile until i get the rest of the stuff for twins.

What do you guys think would be best suited for my truck?

well i run a 64 17 s300 and i am using ddp 4"s but if you plan on twins somethin bigger might be what you would want . i have heard 6x18 is a good size but i think thats 14mm pump territory i will be runnin some 6x20 or 6x22
but i also plan on runnin a very large turbo setup its all in how much money ya wanna spend and how fast ya wanna go

I called a local diesel shop about turbo's and they called HTT and apparently HTT told them that a 64/14 with a 71mm wheel on my truck would not work well at all. Why would it work good on a different truck(24 valve or p-pump) with the same amount of fueling?

Either they arent as familiar with a hopped up VE, or there are cam issues to consider.

The diesel shop I talked to said" I don't know if that turbo will work on that truck or not" I said " I have a fair bit of fuel and I'm getting a bigger set of injectors soon" So im not sure. You'd think HTT knows what there talking about but it just doesn't sound right to me

Yeah I think that they kind of missed the talk about what the VE can do! I talked to them myself and they like to build and sell stuff that will do the job well.
However from my experience with any vendor, if you buy the "only" things you will ever need then there is no more market! Not all but ALOT of vendors will sell you something that will fall short in the long run in order to keep a driving market.
I guess what I'm trying to say is keep talking to people and looking at what is working and what isn't. This we can all learn from. The diesel shop market is slim in knowledge of the VE around me so you are not alone. Heck I stopped in awhile back to order a 366 spring and they had never heard of it nor installed or ordered one LOL. They kept warning me about grenading my pump, so suggested this site to them.

Most of the turbo shops are clueless about VE pumped trucks. We need to get 'em lit by 2k or it's all over.

A Schwitzer 64/71 .80ar holds the record on a ve single turbo #2 only, and that is with a stock 12mm pump! I never have run a single with the 14mm yet. If you dont have an intercooler they are right it wont work well on your truck.

Do you just mean that it won't keep it cool enough?

[KTA]

No the turbo would want to surge all the time because the mass of air it produces would be greater than the mass of air the engine flows. With no intercooler you have a lot of hot air, and that really hurts mass flow because of the low density.

[Underpsi]

Wouldn't any decently large turbo do that as well? My truck will eventually be intercooled just gotta wait til I put the tilt front end and custom rad support in

[Underpsi]

How do you tell what A/R a turbo housing has?

[DTanklage]

it is usually cast into the housing

if not good luck

[Underpsi]

So it should be in pretty much all housings? What does it mean anyways?

A Schwitzer 64/71 .80ar holds the record on a ve single turbo #2 only, and that is with a stock 12mm pump! I never have run a single with the 14mm yet. If you dont have an intercooler they are right it wont work well on your truck.

As Underpsi stated above, I'm pretty much clueless of what 64/71 .80ar

i now that the fist two are the compressor and turbine size.......all tho i could hold them in my hand and not have a clue how to know what size they are.
But the .80ar...............Is this like a % or efficiency ratio?????????
