how does a twin turbo work for the powerstroke and how much more performance do you get with one over a normal replacement turbo?

 

I don't even know if you can do Twin Turbos on a Powerstroke. Even if there was a way to do it, you'd have to have 2 tailpipes instead of 1. But the boost levels and performance would probably be loads better. My suggestion, just upgrade your existing turbo to a Garrett turbo. It's what they use on the new 6.0L Powerstrokes. If it works wonders for the 6.0L it should work miracles for the 7.3. Keep in mind that if you do upgrade your Turbo, you will need to get a bigger exhuast system and better fuel injectors if you want to see and feel the difference.


And that Ladies and Gentelmen, was my 2 cents.

 

Twins are possible........know of some 94-97 PSDs that run twins.....I think that they have one turbo feed into the other turbo. I think you have to pick the right size and kind of turbos to run.


A Garrett GTP38R or ATS BB turbo are nice upgrades to get if you are looking to make some power.......you can make enough boost to blow your stock head gaskets with a chip and Stage II injectors.....



My $.02

 

Oh, Toreador...Where to start...

Yes, twins are possible, though not very common. There are no kits yet like there are for Dodges, so there's a lot of experimenting with turbos to make them work right in pairs.

You do not need 2 tail pipes. Typically the second turbo is the larger one, which feeds to the smaller turbo, so you only have 1 tail pipe.

The factory turbo on the Power Stroke IS a Garrett, though not the same thing that's on the 6.0. We can't use the new turbos. Advancements in technology are doing wonders for these new diesels.

As for the initial question of performance gain, the bottom line is to get an increase in boost, and to have that boost at a usable RPM range. You can put on a huge turbo and get LOTS of boost, but then the turbo lag would be huge, too.

Right now there are only a few aftermarket single turbo replacements for our '94 -'97 PSD's. But I'm sure that'll change substantially in the next year.

 

What DZLJIM said. Also, for the amount of money you would spend to set it up and get it right, you could make much more power with other mods. The only reason I can see to go with twins is bragging rights. Like DZLJIM said, with the right mods you could get enough boost from your stock turbo to blow the heads. Over 32 psi is the danger point, I think.

 

The danger point is somewhere over 42 psi ..........of course if you get it ringed that wouldn't be a problem......

 

Thanks man. I knew that someone would post this. I have read about people blowing heads at 35 psi tho.

 

Does the new 6.0 turbo work on the newer 7.3? I see everyone mentioning up through 97 above but not about the 98-2003 PSD? Just curious... No problems yet but it would be nice to upgrade to the newer turbo if possible...

 

The EVRT will not work on anything but a 6.0, so far.......
