Twin “stock” turbos on an OBS good or bad idea?

What year is it?

Its a 93 F Series with a 16' flatbed. Yeah it needs a second turbo to get going that's for sure.

another thing I was thinking is that since you'd be running them offa each bank independently, each turbos gonna be getting half the exhaust pressure... Need more fuel to compensate

Both turbos have to meet up again eventually, would be less plumbing with one big IC with the turbos meeting up before it versus two independent ones .

on a psd the twin turbos dont have to use the same piping and IC if you dont want them to.each turbo can feed one head.can also do quads with 2 feeding each head if you really wanted to.but you will need more fuel

I saw a big I6 in a KW that has big twins feeding into its one head. It looked cool.

if your doing a real twin turbo setup with a factory turbo i dont think its going to work very well, due to the turbo being spun with only half the air it was originally designed to be spun by.
thats kind of like taking a v8 gas engine and unplugging 4 cylinders and calling it a 4 cylinder engine.

Just put a D66, 38R, H2E on and be done with it. All spool up quick and then you dont have the complications of all the extra BS on a basickly stock truck

 

[Lonesome7.3]

I agree with that idea.

I would get a set of Stage 1's and put a wicked wheel in your turbo.

Does this truck have a chip done ??

 

[Lonesome7.3]

Yes, DP Tuner tooks car of that and it already has a set of stage one's.

 

[Worstenemy453]

Try a wicked wheel in that turbo.

You can go to Irate diesel and get a T4 turbo mount set-up and get something like an S365 i believe. For what you are doing you dont need anything huge.Im not sure how stage 1's would do with a bigger turbo though.

 

[Lonesome7.3]

I was wondering if wicked wheels really do anything.

 

[Worstenemy453]

Its a noticeable difference from what ive heard. When i get my 7.3 im going straight to a s471.

 

[FordGuy100]

FYI Wicked Wheels are meant for Superduty 7.3's, from what I hear they are actually a stock OBS wheel.

OBS Turbo's have way to big of an exhaust housing to consider for twins. Spool up would be stupid slow. High EGT's down low. If they lite it might work okay 2500++rpm's.

 

[Worstenemy453]

Ah, when i gave the wicked wheel advice i had SD in my mind.
