Very nice numbers. Watch out for the stock maf though. We've found that daily driving with about 475+ whp leads to eventually sucking the honeycomb out of its "seat" and the car will hardly run, like as if it popped an IC pipe.
I would take the maf off and attempt to secure the outside edge of the honeycomb to the housing somehow, maybe dabs of epoxy or something of the sort.

It may be too laggy for you, but it's certainly not laggy for a typical GT35R on a stock 2.0. Look at the torque curves - the GT35R torque curve intersects the stock torque curve at 4200rpm. That means there's only about a 500rpm section where you have less torque with the GT35R, but then the next 3000rpm, you have WAYYYYYYY more power. Not bad, imo.
+++1! GT35 FTW!
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.
That's not what he said and is certainly not what he meant, but you could surely do that if you want. You'd have to change the boost, too, but this is no different than having multiple maps for anything else. I have 4 maps that I use for each type of driving I do, and they all have a different combination of octane and/or alky. The point of alky, though, is to use it all the time. If you don't use it all the time, then you just get a race gas tune and put in race gas when you "need" it.

. The point for you may be to use alky all the time, but it may not be for others. What if you run out of meth? Wouldn't you like the option of running straight 93? Don't you have a straight 93 map?
If you think running 28psi gives longevity concerns, then you won't be getting a turbo that runs 28psi. There has been no evidence of reduced engine longevity just because you run 28 vs 22. Also, if you only want to run 28psi occasionally, then you just get a race gas tune and put in race gas when you need it. It makes no sense to purchase an alky kit only to use it occasionally, because alky makes less power than race gas, and the alky can't sit in the tank indefinitely.
I do have a map for if I run out of alky, but I've never used it, because I never run out. I keep spare cans full of it in the garage, and when my low light comes on, I refill it.

. We all don't have cans of alky sitting in our garages, we all don't have access to free parts, installing, and tuning. Evidence as to using 28PSI vs. 22PSI is just common sense. The largets is being dependent on alky to run that meth. I was in a car this past weekend that blew up on 28psi, why? The alky kit failed. Not to mention if the alky kit fails all it takes is one good detonation shock to shatter an oem piston, just an instant. But then again a lot of us have different needs and concerns, and by gosh different ideas. But I wouldn't call them stupid.
Not sure what you're getting at. I have the cans, because I go to Home Depot and buy them. Anyone who uses alky would do the same thing. I use up one can for every 2 fillups at the gas station. It's not like you run out of gas and don't refill the tank, do you? Same with alky. I also don't have a separate map for running out of gas completely, do you?
Getting free parts, installs, and tuning has nothing to do with using alky and boosting to 28psi. You say it's common sense that engine longevity is reduced at 28psi, and I disagree. Show me where that is the case, and I'll believe you, but then I'll also ask why you are bothering to get a big turbo if you're only going to run 28psi occasionally. And then once again, I'm going to ask why you drive around with an alky kit turned off if you're only going to use it at the track occasionally when you could make more power with less hassle by tossing in some race gas. You mention that alky can fail...ok, then why use it when race gas has no risk? You may have a desire to install alky and only use it occasionally, but that is not its purpose. The purpose is to get near-race-gas levels of power on a constant basis without the prohibitive cost of race gas.

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.
Very little of that was right, but if that's how you view alky, then by all means, be my guest. No sweat off my back, and based off your responses, I recommend you not getting it. The expense of purchasing/installing it plus the risk of having it is certainly not worth using it sparingly. I use mine daily at every opportunity, and I race on it frequently. The only time I don't use it is during SCCA events where it's not legal. I've been doing this for over a year, and I'll continue doing it indefinitely. I'll let you know when the added "stress" overwhelms my cast iron 4g63.

Running a car to 28 psi all the time and WOT it does reduce the longevity of the motor. Mitsubishi did not design an engine to with stand 28psi and remain reliable, did they? Or else why wouldnt they have done that? you've done this for over a year now, great. lets see how things hold up after 3-4 years or so.
Warrtalon, I do not disagree with the factory motor being extremley strong to with stand boost, cuz there is a lot of evidence that shows it can. BUT there is also alot of evidence to show ppls motors blowing b/c of the added stress. These motors have proved time and time again to take abuse, but for how long. Most ppl have different tunes. If Im cruising around town I run just 93 and low boost at 21 pounds. Why? cause I want my motor to last. The more stress it sees the greater the chance stuff will break, that is common sense. What is the point for me to drive around @ 28 psi with pump and meth, or 38psi with race gas? Im not racing anyone, Im making no money to pay for the extra gas or meth. And I know the life of my engine goes down with each pull I do.
I severly doubt that your car would last with no issues to 80k on the motor, then a stock Evo untouched by mods besides and exhuast and a few other goodies.But hey you can prove me wrong and keep it for that long and see if she holds out.

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 durabilityBut thanks for your input, it was greatly appreciated and I will consider it

I see that you agree with my point, what's a matter, do you have common sense or something
You know that won't fly on this site. You better be careful making points sir, you may confuse people.

Also evo's run way more boost stock than many other stock FI cars, however they arent blowing up because of it.
