Seriously looking into compounds... Need help tho

silverpsd_06 · Mar 2, 2013

Hell looking at daves just gave me a idea to do mine a little different.. What is your bp to boost ratio like Dave?

907DAVE · Mar 2, 2013

Dunno yet. I know exactly where I want each stage to be at, and got my gate springs setup today...just need some dry roads to see how it works out.

Dave if you are ever looking to take a vacation to Texas I have a lot of beer to drink and a place to stay, just plan it around the time I decide to build a compound set up :naughty: Your setup looks awesome!

What I would be referring to would be the inducer.. My HX55 has a 66mm comp wheel. It is a 66mm inducer and a 99mm exducer..

So I need a turbo with a 88mm, at least, inducer? That's pretty big lol

Powerstroke Cowboy · Mar 2, 2013

Yes at least a 88mm inducer.. The 38R you have now has a 88mm Exducer.. Not saying that is why you need a 88mm Inducer just trowing that out there to give you a idea of what you are looking at..

Alright... And does it have to be ball bearing? Or would a journal bearing work well for an atmo? Cause if so, I could have a large enough turbo in 20min

Journal bearing is fine. Ball bearing is better.

But a Journal would be fine for the set up? Especially so I can get all the mounts and plumbing done. Then upgrade it to a ball bearing after sometime...

Powerstroke Cowboy · Mar 2, 2013

Journal would be fine.. You can always upgrade later.. But if you have the money to do it it would be cheaper now to go with a BB turbo..

Noonman350 · Mar 2, 2013

And let's say the journal bearing only has a 75mm inducer. What would the consiquences of using a smaller turbo be versus the 88mm?

Noonman350 · Mar 2, 2013

I'm not lookin for something extreme... Just a nice little compound set up.

Noonman350 · Mar 2, 2013

Also, where can I find a turbo of an 88mm size? The ones on our trucks aren't even that big I don't think. That's what I was planning on using when. I said I could have one in 20min...

SSpeeDEMONSS · Mar 2, 2013

Check the classifieds here and on compD, there are always good turbo finds.

So you are looking to pull a turbo off a semi??

A 75mm inducer would work for a towing setup on a 5.9L.. It just would not flow the enough air to be a atmosphere turbo on a 7.3L.. A turbo with a 75mm inducer is considered a large single for the 7.3L

The vendors here could get you hooked up with a 88mm inducer turbo.. ask around post up a wanted post in the vendor section. they will have some for sure..

75mm is not a good atmosphere turbo for a 7.3L. you would be shooting yourself in the foot there..

Yeah I was considering it, since we've got about 6 trucks with good turbos sutton around... And alright I'll post up and see what I get. Thanks!

I checked that out... I saw one for a good price, but I wanted to know everyone's opinion on it before i got it. It's the S400SX-72 w/ a 96mm turbine wheel. And it's a T6 ( that's the mount right? )

Powerstroke Cowboy · Mar 2, 2013

Way to small.. It is only a 72mm inducer.. With a smaller exhaust housing it would make a great single..

TyCorr · Mar 2, 2013

Need an s488 or bigger....the bigger you go with the lp the easier it will be working.

I'm just sayin that two waste gates is not necessary unless your spraying or running over 1000hp. All you need is a waste gated Hp turbo. The atmo is big enough at 88-96 turbine w/ 135ar that you won't overspeed it.
