Safe way to make 400-450 WHP?

Over 400 on a 9 turbo w/ e85 isnt exactly safe for the stock motor. To make that power u usually need 30+ psi which means well over 400lb-ft, which is enough to snap rods or lift the head. It can be done, and is being done by many on here. It's one hell of a fun setup, but not one I would consider safe for the motor. I know theres plenty of people running that setup on a completely stock motor, but they are also aware of the risks they are taking.
IMO the safest way to get to 400+hp is with a larger turbo that will spool later (safer for rods) and will make more power on less boost (safer for oem head bolts). Look into FP, CBRD or MAP turbos

something everyone over looks (and i say that because i spent days doing the research) is the 71hta can make 400whp on virtual dyno at modest boost, and not push the torque far enough to breake a rod...and its under 800 bucks.

I totally disagree. There are plenty of guys out there who make 400 on IX turbos on e85 with no issues. I mean I make 520 whp on a stock block with 445ish ft lbs of tq on my car. Am I pushing it sure but I know a good tuner who will make sure the car performs with what I have. I would make use of what mods you have, get a better tuner who knows what the hell he is doing and then go from there to see what kinda power you make. If you feel the need to get more power then I would upgrade to other things. Looking at the origional post you can run a tial bov with a stock maf on the car. I also did that without any issues you just have to block off the recirc pipe and tune for it. It all can be done you just have to have help with what you don't understand. Good luck on the project but like I said start with what you have before you make drastic decissions like turbos etc.

I understand what your saying but upgradeing a turbo and paying x amount of dollars for it and supporting mods for a goal like 400 hp is honestly stupid. I am not saying it shouldnt be done, because lets face it your adding more flow lbs per min into the motor. why not work with what you have, save yourself a grand 1500 and do it on your stock turbo. So yet I still am not disagreeing with you I am tring to save the dude a few bucks and for what he has any good tuner can make him that power safely.

Here is a for example. On a stock 8 turbo with a 10.5 hotside 850's, meth and HKS 272's I made 375whp 370 ft lbs of tq on a mustang dyno. This was done with a **** tune that was basically smoothed out by the guy who "supposedly tuned the car" and all he did really was take out all the rich spots in the tune. For arguement sake the tune wasn't very good at all but I still made that power on a stock turbo with very very little stress on the motor. Point I am tring to make is it can be done and done safely.

would adding the water/methanol kit make a difference on achieving the 400 to 450 hp range with all of the supporting mods in example....
evo 9 turbo with forge waste gate
272 cams
walbro pump
bigger injectors 1000cc or better
tbe HKS
helix 02 housing
3.5 in fmic?
I was told that the water/meth would greatly aid in achieving this power goal....Would this be correct?
