Why drop the compression that low if your only going to be runnif around 25 psi?

Ididriver is right. With that low of compression you could easily run 40psi and be fine. At 25psi I would aim for 17.5 at the lowest...

Ron will more then likely run more boost then that. However my setup wil be using a stock bottom end and std compression so ill be limited for boost or ill have egt issues.

That's is true.
Keeping in mind that this thing has the potential to be a monster, I want to keep it leashed as it will be a daily driver.
My goals are to have it reliably running in the upper 20's to low 30's constantly.
I'm rather quite sure it will run higher once complete as fuel and air combinations are dialed in.
I will be starting out on the low side and turning it up as time progresses as I do want to see where safe operating limits fall. Running a parallel setup is different ground with this platform and I'd really like it to live longer than the first go 'round.
Having Jason working on one as well will both give us data to work with on 2 separate levels and feel it could prove beneficial.
Can't wait to see the madness coming out of Barrnett's shop!

ron at some point you will have to send me your numbers so if this stock bottom end goes south I can do something different

Me, I'd rather see custom built, direct injection cylinder heads for the IDI Ford. A set was built for a 6.2L GM but I never followed up to see how well they worked. Custom pistons required too, of course and probably a new cam profile.

Powersmoke. Our cylinder bores are the same demensions as the powerstroke engines in the 7.3 size plus.. Our turbo rods have the same size wrist pin diameter. Even our rods are the same length but the bottom end is around 132 thousands wider and two of them wont fit the crank rod bearing journel...... Sad thing too.... To build a direct injection head I would use a two piece aluminum head. CNC mill out the coolant passages. Use the same exhaust seats and find some intake seats. Install some valve guides and your running after you design a set of injection lines. I wonder who can make an injector foe this fantacy engine....HMMMM.....

Wrist pin orientation provides for lower cylinder compression without compromising piston crown material.
The majority of the expense will be the pistons and rods.
After seeing how bad the pistons were scorched from underneath, I really am not wanting to take off any material from the crowns.
