My recomended boost levels apply to my style of tuning and my experience and are derived mostly to try and keep my customers safe.
Pushing a pump gas tune 23 psi still gives you a lot of opportunity for the stock ecu to pull timing and save your motor in the event of a bad tank of gas or other problem (such as a water leak or other mechanical problem).
When you are at higher levels of boost on pump gas and alchy the knock events are just more destructive and the reactions of the stock ecu are often not fast enough to provide protection before its too late.

Thanks DynoFlash! This a good thread since we were gonna try this on a Evo IX...
-TBE
-EBC
-S1 cams
-meth injection at 29psi
-AMS dyno flash
Then add a I/C and Evo green turbo on stock fuel pump and stock injectors. Your test shows we will run out of fuel or get dangerously close with this setup. Thank you very much for doing this.

Welcome to 2005.
HKS 280 280 cams w/ TTP camgear degree settings
Stock 2005 turbo
SAFC II
Reflash
TTP-Meth injection (non-progressive)
stock 560cc injectors
3" Megan Racing TBE
We also ran 11.24 @ 125mph on stock injectors.

These look like great numbers considering the amount of mods done on the EVO but I guess this thread goes to show how much peak hp and tq the EVO can produce with a similar setup. Al seems to not recommend running boost so high (~30psi) because it can be very dangerous, like he said in the video, on the Dyno they are monitoring different aspects of the car.
I think some people in the EVO community might make a misconception of this post and try to duplicate the numbers with the same amount of mods. Some might achieve this and others might have bad luck or even worse, possible engine failure. In the end, this thread shows the potential of both the EVO GREEN turbo and what a good alky/meth can do when tuned at high boost level; the restriction obviously were the fuel injectors being maxed out. Just remember guys, don't try to daily drive on a similar setup.

I run 30psi on my Green everyday with methanol. However, I am not on my stock injectors (I have 750s). I guess Al means 30psi is not safe when you have stock injectors.

If you want to run over 24 psi or so with the green you MUST have injectors
However
30 psi on pump and alcky is "agressive" IMHO
In the event of a bad tank of pump gas the stock ecu may not be able to react quickly enough to pull timing and save your motor.
Just becuase you are spraying some alchy on top of pump gas does not make your motor immune from detonation or knock in the event that you pick up some weak octane fuel in your tank
30 psi is on the high side of what I feel is save on a long term basis.
IMHO running 24 - 26 psi gives you most of the power with a lot more margin of saftey in the event you pick up bad gas and with a lot less mechanical stress on the engine.
