tough to tell in a few situations, some powerstroke and even cummins guys only know what they drive, not everybody know's a little or a lot in some cases about all the big diesels, and there potential. anyways more turbo...pius builds one hel1 of a setup, if you need a magic trick for your truck a turbo or two from pius at bell turbo are the answer.

I got a question, been running a s375 with 1.10 a/r on stock fuel liked the set up ran good. Recently put duel k16s and 100% over injectors with an airdog and elites upgrade for it. Took it to the track expecting big numbers. Was only able to get 10.2 In 1/8 mile on fuel and 9.3 1/8th mile with 300 shot of nitrous. Should swap turbos for a s475? And if so what size a/r should I get 1.1 again?

what tuning were you running?

Are you a little mistaken? A s375? Maybe an s371?

Either way, this is what I tell people time and time again, a 366 billet is max on stock fuel. Anything larger is a waste and drives terrible.

Just because someone has a 71-72mm drop in doesn't mean they will loose power going to a 66mm single. The s366 flows as much or more than most modded factory compounds.

I'm thinking you have issues on the fuel side to be that slow or the turbo is toast. Iirc Corb had a 375 in his compound set up.

Who makes a 375?

What would be your rec. for a single with 100% nozzles? Inquiring minds want to know.

S475 I would guess

 

[Steve's_sauce]

Running gearhead tunes (which were set up for stock fuel when I ran it at the track), turbo shouldn't be toast the thing is pretty much new. Am I'm running it in a single set up not compounds.

 

[Stroked777]

Are you sure it's a 75mm turbo? I don't see that thing lighting on stock fuel. Especially with a 1.10 ar

Idk, that would be new to me.

Probably a 72-80mm range single.

S475 I would guess

It's a pretty good all around turbo when built right.

Nope. Tyler has a 472 on stock fuel and he says it's not recommended unless your planning on more fuel in the very near future. All the guys who have ran 371's on stock fuel that I've talked to tend to agree. Most of them have changed to a different turbo by now.

 

[Steve's_sauce]

Ok so I should run a s475 with my fuel setup(dual pumps 100% nozzles)?what size a/r? I don't really tow anything which is the main reason I decided the single route.

First off, what turbo are you for sure running?

Second, what tunes?

Some more info on your truck would be helpful too.

 

[Mike@MPD]

S475 /87 1.0

 

[Mike@MPD]

1.10 never worked well for us

 

[SEABEE08FX4]

There is such thing as an S375, but I'd say you have some tuning issues going on for one. Secondly its probably not the best turbo for a stock fueled daily driver.

I run an S371 and other than the extra power it drives no different than the S366 I had before it.

 

[mpowerstroketwins08]

Has anyone tried the bd diverter valve on their single turbo set ups?

 

[stroker221]

I'm thinkin bout goin with s475/87-1.0 dual k16 and 60's just tryin to decide to have build it.. But can't wait!!
