I'd run that one by the folks over in the IDI forum: Pre-Power Stroke Diesel (7.3L IDI & 6.9L) - Ford Truck Enthusiasts Forums

if your talking about the idi thats in the truck in your "garage" then 15 lbs, if your talking about a psd, then that depends on what year the truck is.

A PSD isn't a IDI...

I cant see why it would not handle any less than 40psi without any problems, i know its a different beast than the psd but compression is much higher in a idi, still the same block more or less....

totally different, the idi and psd blocks are nothing alike. the cylinder walls are very thin on the idi, thats why the idi is prone to cavitation and the psd isnt.

7.3 15 lbs, 6.9 10. Studded the 7.3 20-25 and 15-20 for the 6.9. PSD have something like 19.5-1 CR vs. the 6.9/7.3 IDI is 22 and 21-1. Decompress em and you can add that much more boost. IIRC they will handle something like a 65-1 corrected compression ratio.
