89305RS

Ok i want to run a single turbo on my new motor (373 yes a 373 stroker) it is an offset ground crank to 3 9/16" stroke and .060 over. I need to know what turbo would support this kind of cubes. I want a single because it will be a daily driver and somewhat efficiant. What i need to know is what vehicle can i pull one of these off of? One of my buddys from canada has one on his same identical motor. He said it was off of a 7.3 ford powerstroke BUT i looked up the numbers and it did not match so i know its not off of that. He said it could have came off of a transport truck of some kind. I do not remember the numbers but i think it was an air research/garett turbo. Please help. im confused on what would be big enough to feed the BEAST.

oh and BTW this will be a blow-through application with a 650 DP holley.

You’d have to give a lot more info on what you have and what you expect out of it for someone to give you a good guess at what will work.

As far as the Powerstroke turbo, I’d bet that he’s got either a different year or a Navistar turbo. The turbos changed configurations a bunch of times over the years, and navistars (basically an industrial powerstroke) used slightly different turbos, but they’re all similar, and relatively small (probably top out in the 600-700bhp range).

what else do i need to tell you? I told you my whole setup. It will be a street car so maybe 500-600 hp. He said his is a 2002 powerstroke turbo. Ill get the numbers for ya in a couple of minutes.

OK his numbers are as follows:
1.15 A/R turbine
1.1 compressor
he said that there are 2 stickers on it and the numbers are
818ael06446 allied signal P/N 1825818c91 S/N ael06446

I hope that helps. I have no clue what cam to run on a turbo application but maybe he can help with that.

does anybody know what this turbo is off of?

mor einfo on your setup as in

Heads,cam,converter,gears,tranny,Intake

what power band you want to stay inand where you would like th eturbo to spool at. what yours max rpm your gona shoot for. HP goals.

all we know is daily driver 373

i already said i do not know what cam to run with a turbo. I also stated that i want 500-600 HP. I have dart iron eagle S/S heads, Ill get the convertor to match the cam. It wont be seeing anything over 5500 RPM i want the turbo to spool as soon as possible. That is what everybody that can hook up wants. and with a turbo this big i think it will keep with me for whatever RPM i take it. Itll have a single plane street dominator intake. 700R4 trans and 3.23 posi but i think that info is irrelivant to a turbo in any way. You can put any trans and gears behind it and itll still run like it did with any other gear/trans (the motor will anyways)

Gears, cam, intake, and heads are all tied together. The make a proper selection of any one of these, you need to know what you want for the others. Likewise, when you pick a powerband (RPM) you need to select all of these to meet your goals. THey are relevant.

89305RS

CAM and CONVERTOR are yes tied together BUT heads and intake are not. Sure they are all tied together with bolts BUT you can bolt on a set of heads and intake and get the same powerband from the cam but more power in that powerband. All heads and intake are for are more power. All im saying is i want 2000 to 5500 RPM boost. There is your powerband. All i need to know (originally asked) is what this turbo came from.

ljnowell

Sorry you are wrong.

and by the way, being a smartass isnt a good way to get your question answered. If you know so much, figure it out yourself,

whatever you say. :hail:

**warning. im pointing out the obvious here***


if you make a motor to make tons of top end horse power, and gear it with numericly low gears, it will be slow.


if you make a motor that produces tons of torque, and you stick a huge gear in it(numerically high) you wont be going as fast as you could.

if you run a super loose converter, badass (numerically high) gears and have a mid RPM motor, your car will want to over rev, and be slow. and get ****ty milage.



they're all connected.



that said, just post the following:
"i'll pick my converter/gears/tiresize after i make the motor"

then build your motor

then think out the drivetrain.

It's obvious to me just from this that explaining turbo theory to you would be a waste of time, since everything *you* know is right and the truth is irrelevant. This attitude tends to drive potentially helpful people away, because they'd rather see you fail than pull their hair out trying to help someone who doesn't understand.

Whatever everybody wants to think is their own opinion. I firmly believe that they should keep it to thelselvs. I came in here wanting help finding out what the turbo i WILL be getting comes on. Then the post ****** come out asking me what my setup is. I dont give a flying freak about what everybody wants to know. I came here for one thing and one thing only. In no way was i being a smartass about anything untill ljonwell called me one. This is a tech board for help and info. I needed help and didnt get it so i asked again then stupid questions come up like what heads do i have what cam am i going with etc. I wanted to know what turbo would support 373 cubic inches and also give me 500-600 HP. I do know about turbos i just need to know what this perticular turbo came off of.

TechSmurf

Answeing that statement accurately *requires* us knowing more than just how many cubes you've got. How are we supposed to know that you didn't want us to answer that statement? You're the one who posted it.
If you re-read your initial post, it is not a "one thing and one thing only" post.. it's a request for advice an opinions, as well as a "what did this come on". You asked for our opinion, now that you don't like it you don't want it... make up your mind please

ljnowell

OK, I am willing to ignore the fact that you are a complete ***, and are rude the very people that are trying to help you. I am also going to ignore the fact that you obviously are in the dark about how heads and intake can affect the choice you would make for a turbo. Instead I will spell it out for you. Without knowing what kind of flow your heads have and what kind of intake you have it is impossible to give a good guess at a turbo. They are related, if you put too big or small it will not perform at all, and in some cases not even work. That being said, this is an internet forum, and when you come here and ask a question, you are asking opinion. Everyone has one, and more than likely a few people now have one of you. If you dont want an opinion, then dont ask a question, see how easy that is???

TechSmurf

Precisely. You'd think a stock turbo from a 3.0l supra would work great on a 2.8l V6.. but no, if you miss the fact that the supra's volumetric efficiency shames the 2.8's like no other and the supra redlines at 6800 while the camaro redlines at 5000... regardless of how undersized factory turbochargers tend to be, the combo really only works when you're willing to accept not having full boost until 3500 rpm, shifting a mere 1500 rpm later, and falling out of your peak boost band in the process. Volumetric efficiency and RPM band are *everything* to turbocharger sizing, meaning heads, intake, and cam are *the* most important things to know (next to displacement) prior to turbocharger selection... displacement alone is utterly meaningless.

alrighty i found out that the turbo is a 444E from a 7.3 powerstroke. Thanks for you guys' help

ljnowell

My guess is with your knowledge you will be needing more 'help'.

89305RS

now whos being a smartass????!?!?! Well ill just go to camaroz28.com for my 'help' from now on.

MrDude_1

good luck.

theres alot of dip****s there too.

89305RS

ahhahahahahaha yes i know this.
