I purchased my fuel pump, and instead of running a rising rate fuel pressure regulator, I'm modifying the internal regulator and setting the static fuel pressure to about 60 psi. That should supply more then enough fuel for my goals (300 whp). Additionally, I've changed plans a little. I'll be pulling the head to install carpenter heavy duty valve springs and a custom thick head gasket from cometic (84mm bore, .070" thick) this will lower my compression from 12:1 to about 10.29:1. Depending on how the dyne tuning goes, this may allow me to turn the boost up to 15ish psi. This is going to be FUN!!!!!!!
Dude, keep talking like this and I will have no choice but to notify Homeland Security of your bomb-making plans! 
Seriously, consider the advice of everyone and don't stray too far from the proven....at least that is my .02.
Good Luck with whatever you try!

are you atleast going to map it via a power commander and a hub with the 5v input off of a 3bar map?

Won't matter with only 60 lbs. of fuel pressure if he tries to go to 15 lbs of boost.

Use the RRFPR, At 15 pounds of boost I had 85 lbs of fuel pressure 39 at idle on my ZX14. It was dyno tuned. See what 01smokes did with the BEGI 2025 RRFPR I sold him with my turbo kit. I don;t know if he used it or not. You can't skimp on fuel pressure. If it detonates on the stock pistons for long it will collaspe the ring lands of the pistons and you could possible damage the cylinder which would have to be sent off fixed and replated ($$$$). They work great and I have run mine for years.
I still got it ill sell it cheap if you need it or want it
If he don't want it i'd like a shot at it.

Thanks the the advise about the rrfpr, I just purchased it from Art. At 85 psi of fuel pressure on 15 psi of boost, do you remember what your injector duty cycle was at?

No, for my purposes (drag only bike), I really don't see the need. I'm denoting it in the middle of the winter, so it will be tuned for low air temps. And I'll tune it for the top gear which isthe highest load. I'll lose some power in first and second gear due to it being fat down low, but that will be fine as I'm sure it will be a handful in the lower gears as is. Why do you think I need a multi-function hub with the map sensor?

i can tell you the last time mine was on a dyno at 100psi on 10lbs i was at 90% duty stock injectors

The map sensor activates the fuel map for on boost fuel control. alot of guys with larger injectors run this way. I have this setup on my Busa project. I think I was at about 85% duty cycle. The most FP I ever made that I remember on the gauge was 90 lbs.

The ECU had to be reflashed to work with the GM map map senor and the PC3. I have 62 lb per hr. injectors so the FPR had to be stepped down to a 3:1 which is an easy conversion. I am running a GT28r DBB turbo and this setup makes over 380 to 400 HP at the wheel and runs like a stock bike off of boost. It's what the real street guys are running because the rules didn't allow secondary injectors until this year. Basically the bike runs off of the reflashed ECU until it makes boost then the map sensor sends a signal to the PC3 USB port which adds the extra fuel need for the boost it was tuned for. in my case 20lbs. It sounds complicated but it really is not. Steadmans Motorsports is a good turbo tuner. He can handle all of the reflashes in house and tunning. The 14 that you got the kit off of used larger injectors with a PC3 and was tuned on C-16 and made 390 Rear Wheel HP at about 18 lbs. of boost. It was a monster to ride. The motor had the -2mm rods and turbo pistons with good valve springs. Very simple setup. On the 14 you will have to go to larger injectors if you want to make big HP.

It ads a % of fuel based on a 5 volt scale from the output on the 3 bar map sensor. Just need a ps3usb and a mutli hub with a map.

The bike runs good now but its Just to hard to ride with out a boost controler and I'm thinking of making a lot more power this time around 400+ HP

At what point do you need to seal the frame?

I sealed mine, The place where it will leak and you might not see is in the frame up around the neck. the rest I just put screws in. I would say if you plan on making 10lbs or more.
