Meth inj vs. Upgraded turbo
I have E85 and Methanol readily available in my area and guess what I did? Neither. Ordered an FP Red which should be here today and going to see what it'll do on plain ole 93 octane. I don't like how badly the boost fades on the stock turbo and it spools up a bit too quick for my tastes as I hit boost in regular granny driving too easily if I'm not careful.
my red is ready to go as soon as the rest of my parts arrive...for a dd street car, the red will meet your power expectations...and if it doesnt, id throw in a e85 tune and you'd be set
Not that I am doubting you more of a question. Wouldn't the meth provide better driveability since you still have the stock turbo on there and not a laggier one that requires significantly more fuel, which untuned or not perfectly would sacrifice driveability. Since with meth you would need to worry about WOT tuning as far as changing settings (i believe). Either way i guess you could argue that both with proper tuning should be fine, but i guess meth would be an easier tune correct?
Ok before I continue I must first clear a few things up so that my words are not in anyway twisted . I am in no way saying that meth will not make power or its bad for the motor or anything of the sort . Now what I am saying and stand by 100% is that once you rely on another injection system ( which may I add is NOT all that great to start with ) for added power that only leaves the door wide open for all sorts of failures . Those pumps do go bad on a very regular bases and that to me is not the best thing to depend on . The meth does ZERO for "driveability" !! What I mean by driveability is partial throttle boost and how the turbo comes on also how the car drives around town from light-to-light . The car with the stock turbo is pretty jerky and no tuning will stop that ! Having a bigger turbo gives you great predictability in tuning . Think about this , unless you're using a multiport injector set-up ( the ONLY ones we have installed ) you are just pumping in meth into a large chamber and hoping for the best ; you will be betting on the fact that everything will randomly work its self out - call me crazy but I do not like that idea . Also in a car which is well known for going lean on #2 , I like to somewhat able to ensure the amount of meth going into ALL cylinders at AL times , once again call me crazy or a control freak - yes I am guilty of maybe both ..

I'm not sure how different meth is on DD's between the Suby's and Evo's as I'm still learning Evo's, but I know more than a fair share of DD Suby's that run Meth.
That being said, my Tuner actually lost #4 due to his meth failsafe not functioning as intended. The cause turned out to be the wrong connectors on the board, and in the end it made him upgrade pistons and turbo, Dom 4 @ 550whp, so he's happy.
He also switched to e85, no more need of Meth, and Super safe tune. If e85 is available, I'd suggest that as your best option.

I couldve swore I have seen people with good tunes and all the bolt on's running upwards of 380whp, and that is without headwork and cams (i thought anyway) if that was true i wouldn't foresee 450whp on stock turbo out of the question, yes/no?
450whp stock turbo and engine is out of the question

And FWIW water injection has been around for years. GN guys were doing it in the 80's. Yeah the technology hasn't improved to leaps n bounds but the failsafes that are available work like they should. Meth is the cheap and easy way to make power. If you want 450 hp your odds of the motor popping are just the same with or without meth. They say you gotta pay to play. So are you playin or not?
Not saying it could be done, but it would be fun to try.
I'm just not seeing it, even on a dynojet....you'd have to port everything, meth, all the bolt ons, and alot of boost...and i still dont think it could be done...but good luck if ur gonna try 
If you do get to 450 on the stock turbo it won't be for long period of time. It can be done BUT something is going to go wrong and it will get expensive. Your better off just putting in a bigger turbo. I got 340hp to the tires and I am going to put in a cam and an Intake manifold. I'll tell you where I am after that. Hopefully breaking 400 on a DD. After that I am going with a bigger turbo.
