i love how people like you say something this "i also dont plan on running this map all the time. when i go out racing or just for fun every now and then."
it doesn't matter how much or how little you run your turbo/engine like this. it is NOT SAFE...how do you not get that?? you have no margin for error and all it takes is that split second of being too hot and BOOOM. $3,000

because im not doing back to back to back runs..... like it or not... its my motor...
im fairly new to tuning... i pick up on things very fast, i've tuned 9 other evo's, multiple maps for friends....
im doing the testing on my own car to see what it likes...
im going to make a few maps and enter them on DLL or test them at the strip.
cheers!

I'm uncertain of what you are trying to say (100% 'safe and normal'), but introducing methanol into the equation isn't really going to prove much of anything.
Likewise, the proper way to do this is to have the car in a controlled environment, and map for detonation threshold at relevant rpm points with different, fixed boost pressures, while recording power at the same time. There will be a point whereby reaching the detonation threshold for a greater boost pressure does not exceed the power generated by reaching the same threshold at the previous (lesser) boost pressure.

Many years back it would have been considered insane to run 23psi on pump gas and now it is an everyday occurance. Just because he is running 28psi on pump does not make it ridiculous. As far as Vin #'s, there are many cars on this forum that would not be worth purchasing based on what I have read.

safe as in 11.5 afr, 16* timing, 26 pounds of boost for methanol
my 93 tune that i run is 11.1 afr, 13* timing, and 22 pounds of boost

Again, the only way to do what you're trying to do is to record power at the knock threshold at various boost pressures in a controlled environment, all being equal except for the ignition curve. I don't believe this would unearth anything especially surprising, simply because you wouldn't be the first to do it.
Actually, I find your results quite interesting, as I am not sure how many have actually taken the IX to its limit. Granted, it may not be the safest thing to do for your engine... I'm sure the VIII's have been pushed to the limits many times. The only way to know how far we can safely raise our boost on pump gas is to push the limit some... Once we find the limit, we can back off a few psi for safety.
Don't know why anyone here is complaining - if someone on here wants to be the "guinea pig" and do this testing using his car - this can only serve to benefit the Evo community...
Most guys I know are boosting 1-2 psi higher on pump gas with the IX's as compared to the VIII's, given the revised coolant passages, etc... but what if we could be safely boosting to like 25-26 psi on pump?
Only one way to find out...

And what if there is no more power from it? That is the point of contention, as there are quite a few 'fudge factors' to be addressed.
This is where the picture gets complicated and potentially dangerous for those who read something like this and draw conclusions that are possibly misleading and equally detrimental.

Ok, but use of methanol isn't going to reveal anything useful here. If I take a 'safe' pump fuel tune and turn up the boost, it will make more power. If I toss methanol into a 'safe' pump fuel tune, it will also make more power. This isn't demonstrating anything.

im not using methanol.... this is just on 93...

this definetly isn't safe by any means.... but thanks for the defense!
