Looking through some of my data logs, I have a few here hitting 260 load at 6500, but a few hundred RPM after 6500 I was off the gas and slowing down, if you would be interested in seeing those. Tonight I might go out and screw around as with my current set-up I am not running the boost I can/should be. I am going to get it back to what it used to be so I can dyno it to see what kind of gains I get from my mid October mods.
My log's exact numbers are at 6500, 261.25 load and at 6562.5 I let off and load dropped to 56.5625. Peak in that log was 327.4375 at 3718.75 rpm. (Log was printed out, just happened to have the printout in my laptop bag at work.) I will have to, next data log, wind it out till the rev limiter kicks in.

I was running a 3076 on my Eclipse years ago on the stock bottom end with over 100K miles.
The Evo bottom end is a lot stronger than the Eclipse's was. The stock Evo block and internals, assuming a safe tune, should be fine into the 500 who mark. That's past the green territory and well into 30Rs.

For reference I renamed 2 byte load to just "Load" so you may need to change that in my def or change your 2 byte load tag. A big thanks to Bez and Eric for coming up with a formula that my little brain could figure out how to implement. I didnt have any time to test this at anything other than idle so there may be some bugs that I havent discovered yet.

Tested this evening and I have a log to post, but putfile is being retarded. Anyone want to host a small log?
Until that gets done, my car on low boost (Green, cams, 21psi, etc.) is reporting 40.8 lbs/min at 7500 (load of 235, 2043hz, 2.4835 g/rev) using the above listed formulas and 2 byte load as the basis for calculation.

Who told you that you need to pull the head or replace rod bolts to run a bigger turbo?

I've heard of others replacing the rod bolts without popping the head by just pressing them in with a tool, but I also heard that doing it that way will stress it. I'm not sure which is true here but I know for sure the strain on the rod bolts by constant revving into 8000 range
JB, just post a screenshot of the log

Eric, yeah the peak g/rev was 2.81 at 22.8psi. So its been awhile since I thought in terms of lbs/min to hp but as I recall the rule of thumb is supposed to be like 10hp, is that right? IS it 10 flywheel or 10 dynojet? The boost actually peaked a little higher than I remembered it being until I looked at the log just now. 23.4 peak right now and 21 by 7500.
