I would not deck the block. That would raise the compression ratio even further, and that's not what you want on a engine with a turbo unless you are going to keep the boost very very low. The later Ford powerstrokes run a lower compression ratio so they can run more boost safely. That's part of the reason why they seem dead until the turbo kicks in.

The main thing you need to do on the rebuilt 6.9 engine is buy and install the ARP stud kit for bolting down the heads. The 6.9's used small bolts to hold the heads in place, and if you run a lot of boost with the turbo, the studs help keep the heads down on the block so the headgasket won't blow out.

 

He said deck the pistons

 

First...Relays and running lights...I think the way you described doing it will work great...My problem with relays was I didn't know why one was needed nor how to power it...your description explains how to power it ans I think it will take some load off of the light switch itself. I think that's what I couldn't figure out...That should allow me to install not one but two relays...one for the truck and one for the trailer...Of course I would have to remember to flip both switches on.

Second...The 6.9 overhaul...I already have ARP Head Studs, Gaskets, Seals, & Bearings for everything...Only thing I don't have yet are the pistons, rings, and heads...

I am not sure what you mean about decking the block...I was thinking of shaving the pistons to lower compression a bit for the Hypermax Turbo and intercooler...That's what I'm not sure of yet...the shaved pistons...I like the plug & play of the hypermax...plus it would be a lot easier for me vs. coming up with all the parts to put a turbo system together....

I am not looking for extreme boost...just in the 10 to 15 range. The lower compression with head studs in my mind is to protect the head gaskets so I hope to not ever have to deal with that, but like I said...I am just thinking that way, but I could be very wrong in my thinking...I know that from many years of wrong thinking under my belt. But I guess that's part of the territory when one tries to do everything without going to the experts or just buying a complete drop in engine...

That is the headlight relay article, it should help you understand how relays work which you can apply to other electrical circuits.

 

Hey thanks bashby...I forgot that was in the stickies...see my old brain needs help LOL...

 

Right, there isn't, and neither do I remember seeing such a thing discussed here. I posted that because it contains some good 3G swap info from the past.

 

i installed a relay on the running lights of my f250 a couple years ago, and it works just fine. just have the parking light circuit of the OEM switch control the relays, and you have no extra switches to worry about. the PO wants one for the truck and another for the trailer, great, run two relays both controlled by the headlight switch. all the work is hidden, and you don't have to remember what 12 different switches do

 

Sorry, I missed that. I am used to have the block "decked" or the pistons "shaved".
