I was thinking of using a cummins optiair. It can flow 200-1200 or so cfm depending on model. It also uses off the shelf filters.

Any noticeable power difference when driving? Just curious.

If you ever get around to installing it do post the results. I know that waste gate turbo produces the most cfm but whether it justifies the cost of one is another question.

There aren't exactly many turbo choices for the mf. The "d" turbo produces the most cfm. Though it is possible to put an lds turbo on an ldt. It produces more cfm than the "d" but I'm not really sure what the results of the swap would be.

No need to re hook up the fdc. Just turn the fuel down a hair. That's the reason many people have increased power when they bypass the fdc. It retards the fuel. That's its function. But your fuel screw sets the max rate the fuel can be delivered. If it runs hot just back it down. Same...

If you bypass the fdc and it sustains temps over 1200°F then you can back the fuel screw down. More than likely you won't need to.

Remove the turbo before you drill and tap the manifold.

Just be sure to watch your egt's after the bypass.

Yup. They are bad about allowing fuel to get into the engine oil.

Then chances are your pump is bad.

Yes. The cover the plug hooks to. You need a 7 amp slow blow fuse.

They are cheaper and easier to deal with than an in line pump also.

When the main power switch is on.
