D-Max turbo on a multi-fuel?

[Lonesome715]

They went back? I would love to speak to them and find out what kind of problems they had.

Performance issues as I recall, two of them were threads here where people installed a 5t turbo with a wastegate.

If you're determined to force more boost down a 22:1 CR engine, that is your own prerogative. Just know there's a inherent risk in doing so.

I took off a wastegate to put back on a D turbo but that was because it was damaged. I eventually did obtain and install a good wastegate turbo. Who was the person who had performance issues?

Do you have a link to your biuld?

Thanks. I wil take the time to read that.

In other news. I sold the D-Max turbo. I got an offer I could not refuse. So now I am thinking the Garrett from the 97 PowerStroke I have would be a goos choice to use.

Good solid unit.

It is a lot simpler and non-waste gated.

Corky Bell wrote a book titled "Maximum Boost" on turbo installation and application. I read the book and went to his shop to discuss what I had in mind, it was great to talk with him and learn. He is located in Texas.

Do it right, don't blow it up.

A 97 powerstroke is waste gated. I believe any way.

 

[Lonesome715]

I have to find that book.

I have two early PowerStrokes, neither is waste gated.

 

[jrobinson5093]

Ok I know the 99 to 03 7.3 are I have not dealt with the early ones often.

The turbos on them, I think, are more adapotable to other biulds.

I think this is a neat idea, but likely easier to pop one of the 3 or 4 series turbos that were originally on these engines to experiment. JasonS has some good info in it. Maybe look into one of the versions that he did not try?

I find that my C turbo with the FDC bypassed does pretty good for general driveability. These trucks were not designed to blast out high HP for extended times as required for freeway speeds on grades. As a rule of thumb, smaller turbos spool up faster and give boost earlier and larger ones do the opposite. The variable turbo design was intended to span that gap. If you move to a "bigger" turbo you will likely loose out at lower RPM. It's all about trade-offs.

Lots of this info has been covered many times. Here is a thread from way back. The guy actually had flow maps to tell if a turbo would work, not just "try it out" being UN-informed. Sure would hate to see someone cry about a trashed motor over something stupid.

Good points. I should have used the term better turbo than bigger one. I can see how a different series would be better than pulling one off a pickup truck.

As for the VGT issues. Convert it to a vacuum unit. VW has been doing this for years. The turbo might not be a VGT turbo to begin with. The LB7 d-max is a nonVGT turbo. They started using VGT turbos on the LLY. The LLY turbo is good for 26psi and that's at the limit of its boost map. With an after market compressor wheel it can get safely to 32psi. Just some food for thought

 

[Lonesome715]

I did not know that. Thanks.
