All it takes is one pull, one time, or something really small to go wrong and you can blow your motor. And lets not forget- no warranty anymore...but this is the risk you take when modifying a car, hence why Mistubishi doesnt push the car any farther then they do to the public.

No way, that makes no sense. If you tune for pump gas, then turn on the alky, the car will get flooded with the alky and run rich as hell while making no power. Where'd you get such a crazy idea? You can do that with race gas, but not with alky. Plus, you'd never get the benefit of the alky, so that whole suggestion makes no sense.

Since boost has a direct correlation to torque, and since BMEP is a function of torque, without a doubt cylinder pressures are higher. Most typical street production turbo cars are doing around 200-250 psi but most modded Evos are doing well over 300 psi... I vaguely recall an article describing Formula 1 engines doing around 219 psi @ 19000 RPM, but they don't have to last beyond 2 races...

Please go into detail of what you think was right and what you think was wrong 
Please explain in detail how running 28PSI on an OEM turbo or larger is just as safe as 22PSI and will not reduce engine longevivity. You are right, it does have some expense, maybe one day I can get some free parts and tuning like yourself I also don't remember asking you about your daily activities and when you are allowed and not allowed to use meth or how many free maps you have and that you run SCAA events so, that's all you I guess. Also I would immagine your cast iron block can handle the boost and WHP, I would be more concered about the cast pistons
. I also want to know how your 1 year of running is enough to overcome years of Mitsu Engineers who do nothing but test engine strength and durability
But thanks for your input, it was greatly appreciated and I will consider it

Mitsu engineers design the car to outlast the warranty... well, not that anyone here has one left, but still, that's their job... make the company money, not expenses.
Nobody said anything about running 28+ on a stock turbo.... it's a GT35R.... and it is much safer to tune at 28 than a stocker... less heat.
The alchy kit and 28psi being there all the time sounds good to me, how about if you don't want the alchy to spray.... DON'T FLOOR IT
Eventually, with a big turbo like the 35R, I think the longetivity gets thrown out the window... If you've gone that far, chances are you're gonna go either 2.3 or a forged 2.0 high rpm setup....
Wow, why don't you rip on the guy for getting free parts a few more times

I don't think anyone would agree that Mistu designed the Evo to Outlast its Warranty. Even 100% stock the OEM clutch wouldn't make it. Transfer case issues and synchro issues in the earlier VIII's. The IX's have known freeze plug issues. 28PSI would further reduce the Engines longevity IDK how anyone would dispute that.
I think the issue is that you assume too many things. You have your way and it works for you great, and that is great. Gas is readily available and every street corner, a far cry from Home Depot and constant usage. Do you keep extra cans in your car?
Assuming race gas has no risk is also a mistake I believe. Having access to free parts/installs/and tunes has a HUGE effect meaning if something breaks, oh well, free parts
Why drive with it off with a 93 octane boost? daily driver, why use alky all the time? Why need to run 28PSI all the time? If you question whether 28PSI adds more stress to an engine over 22PSI, then I seriously question your basic engine knowledge to begin with. By definition it is more stress and combustion pressure.
Why turn off a Meth kit? IDK, I was thinking to conserve alky, no need to use it all the time. Also why did you assume I would ONLY use it at the track. I never said that, more of a daily commute kind of thing, no reason to have it on there. Also there are studies that show it can damage your motor, some would disagree with you there Clay. Also most of us have to pay for our mods and use them at our own expense
Race gas carries risk too, it damages sensors and you can still blow up on that as well, especially if you think that there are NO risks.
Thanks again for the input and I will seriously consider it for my next purchase.

Also about carrying extra cans in the car you dont need alky alot to be honest. My friend fills up his alky container after 2 full tanks of gas.
I agree about race gas not being as safe as people think. But lets be honest if your running race gas or meth you should have a block ready to swap in. It may last you till 80,000 miles or it might go within a week. Thats the biggest problem thier is no set time of how long a motor will last with X mods.
Oh and by the way dont hate of people for getting free parts. I have to buy all of my stuff with my own money, but if you could get free parts wouldnt you do it to
?If you want your motor to last to 100k just leave it stock

Wartalon, High PSI, White05evo and the others involved in this little sub debate:
If you guys dont think that running this much HP on the stock motor isnt stressing it you might want to pinch yourself. The rods, Pistons and entire rotating assembly were not designed for it. can you do it? Sure, but for how long? We dont recomend Customers push a stock motor past the 500 mark. We didnt just make that up, we say that because after that level you are severely stressing the stock internals. Thats what a built motor is for
Hell we have taken a stock EVO VIII motor to over 550 with Stock Block, head, Studs, Cams but I wouldnt expect it to last too long.
AMStuning is doing a a great job and those numbers are fantastic for what is done to the car. We love testing the limits of this motor. its a great piece of engineering. I can assure you though that Atlantic is recomending that their customer look into building the motor.
I dont think there is an intelligent person on this site that doesnt understand that a great deal more HP on stock internals will stress the motor more.
VERY nice number AMStuning!

Thanks Eric, its nice to have some expert insite. I am also slightly concerened as to the fuel pump debate as to if one is needed on a IX with a stock turbo, boltons and a flash.
Any insite to that?
