two turbos one engine

[RCCUMMINS89]

That's into a realm that I know nothing about.

[Sutter1stgen]

If your staying ve then s472 is what I'd run. Stackx2 (John) is going to run that charger with a t6 1.10ar housing on his p pump truck. Ve pumps need a quick spooling charger. Call forces inductions.

[RCCUMMINS89]

I believe a 14 h/r pushing as much as he can would benefit from a larger primary.

He should be in the 600-800 hp range.........if all the fuel gets burned.

[93flatbed]

Yeah that's my problem, I need to get the primary going as quick as I can. My sub par math tells me I need to be in the low 100's on cfm with the primary, but as we all know we have rpm problems. That's why I was thinking a ball bearing Gtx wheel would be my ticket but man those are a large chunk of change! The EFR Borg warner turbos are a hair cheaper but still in the mid 2k range.
I also really think the 351 is going to hate life, so I'm thinking of changing out the secondary also. Time and money.......

[Sutter1stgen]

When i talked to stomp a while back about purchasing a larger primary, he said anything you go with will be better than a ht3b. As long as it is comparable in size obviously. His reason for saying was the technology has gotten much better. You don't have to break the bank on buying a new primary. That's why I suggested a Borg turbo.
As for you high pressure side, I'd definitely go with a charger that has nice exhaust flow characteristics. You don't want it to be a choking point.

since I'm still pissed about this; Mods delete if needed?
This,


Made me do this;

and this;

So I couldn't make this go vroom vrooom;



Yeah I know, I know she is going to be pissed but hey I'm not exactly happy either.

[RCCUMMINS89]

The more I drive this 62/68.............

I think a sweet set up would be this 62fmw over a 475 sized charger

[Tacoclaw]

If she's anything like mine, she'll never ever ever ever ever ever ever ever


ever get on this site. You should be good. XD

[RCCUMMINS89]

I know, I went around and around for over a year on which turbo I wanted........ask sutter. Holy cow.......it was ridiculous.

I finally bit the bullet and went with the newest technology that borg offered..........and then took a few months to someone who could make it happen (my builder).


It was the best decision I made. This turbo, with proper tuning, spools faster than my he351cw did. Originally i was having laziness issues and egt issues in 5th. That was solely a boost leak/small i/c issue. This thing has ZERO lag now that I have it dialed in.


If you were to add a turbo like this with a similar low press. turbo........I think you'll be in business.

[93flatbed]

After talking to some very knowable diesel performance people I'm now deciding to go with a 62/68
,4202 combination. They think its going to be a bit warm but will get going quick enough to be fully lit in the relatively short rpm range us rotary pump guys have to deal with.
So in summary, I need to spend some more money that my wife will probably say but now we need new furniture. If that happens I'm putting up more pictures.

[Remps]

Well either way the results should be interesting! Jmo, but if you are going with a JB instead of a BB 4202 why not just go with a S471 or S475? Oops, I read back and saw that you are going with a gtx.

[93flatbed]

After a few price quotes I may sell off the whole mess and start over. I'm honestly not sure at this point, work is horribly slow. I've always promised my wife I won't use the general saving account to purchase fun things.

So to all you General motor product owners that are under warranty or have extended warranty, please go break your rigs. I will turn a blind eye to most aftermarket parts.......

I Almost sold all of mine a few months ago when I was looking for work. Finally found full time work a couple weeks ago, 40 hrs a week for now. Really glad I didn't accept any of the crappy offers I was getting, I'd be kicking myself right now. I had one jerk freak right out (via text message)because I wouldn't sell him my parts truck for $150 bucks when I wanted 500. Which I think is a good deal for a complete (except for the fan) 93 12 valve and getrag trans(which needs a clutch) Schit, I paid nearly 300 for the starter 2 months before the clutch went on it. Schit, just fab some triple hx35's, that'll outflow a gtx4202 anyway for the price of 1 new secondary or cheaper, and I'd bet they spool just as fast. Add a fancy external gate when you do have the money and you'd be laughing. Of course always easier to say it than to do it lol.

[93flatbed]

3 crossed my mind. Then I looked at the pictures over on Compd. Looks like a plate of spaghetti fell onto the engine. Although I'm not against showing off my poor tig skills......

I'm not saying I would ditch the entire project just the turbos I thought I needed. Then again I was talking to the lady you see up there ^ a few weeks ago about how nice it would be to have a mega cab 6.7.

[DMan1198]

I don't really have anything to add to your choices but I happen to own a 6.7 cummins now along with my first gen (though mine is a crew cab long box) it is really nice and comfy but there are some features where I like the first gen more. Price of parts is a big one, and to get it tuned properly can get up over $1600
