does anyone have videos of a 7.3 idi with a 6.2 gov spring in it. would like to hear one at full throttle

wow thats crazy rpms for an idi
That doesn't make you nervous? How is the power curve with the new governor spring in it? What do the IP wizzes think about this "upgrade"?
I'll not speak for the Ip wizzes here, but I will say that bumping the governor to 3800 is considered pretty safe and anything over 4000 is asking for trouble unless you rework the engine quite a bit. Ford already bumps it 500 and 38 bumps it another 500
If it made me nervous would i do it?
Well, you've blown up one engine, dropped a ton of money into this one; All I can think is maybe you have expendable income and just don't care.....

What RPM does that allow our pumps to get up to? And not to hijack, but does anyone know what the governor is on my pump. 1994 factory turbo pump. Is it 3300?
Governed RPM for the Ford pump is usually 3300 ish, all years. It can be kind of a flexible governor where you can wring out a few more RPM than that if you really try. I could even believe 3800 on a stock pump, probably a rebuild that some builder turned up mildly. The conventional wisdom is that the valves can start to float after around 4000, but you're welcome to challenge the conventional wisdom. David has done it and his engines have tolerated it at least to a point. To be safe though <3800. I think the reason most people don't push it is that power gains at that rpm tend to be pretty minimal according to dyno graphs members have published here. Recall that these engines are designed to make peak HP at around 3300 and peak torque between 1400-1800. Not to say you aren't gaining any power up there and that it doesn't feel really powerful by the seat of your pants. Also you can build an IDI to tolerate those RPM easily, it would involve upgrading the valve springs and balancing the entire rotating assembly to say 500 more rpm than you ever plan to use. But then I'm probably being overly cautious. I like my truck and I don't have money to swap engines right away. If I break it, I'm probably walking.
