T70 with a big *** street port...pretty cool
T70 at 1.6 kilo's...even better
Hitting 75% duty cycle at 25 psi with 5900 cc of fuel....priceless

If I recall RallyMotorsports from Joisey had a 91 TII w/ T70 and I think they didn't end up using that because it was to big... something like that. They were in turbo-mag. years ago with that setup....Not to talk you out of it or anything..cuz you'll beat me

A pump on each rail, 1600 secondaries and 850 primaries with an SX regulator.
this setup has gone 9.10 in the quater at over 150mph in a 3rd gen, with 30+psi
running a haltech. What i am saying is i dont see why you guys are having to run so much injector in your street car. You can also use lines already on the car!
this setup has been used for over 2 years and still works great.

Yes, it can be done, I just want to hear details. I am specifically interested in the fuel pumps.
I think alot of people out there are running single supra/cosmo/walbro/etc. fuel pumps with there xxx/1680 setups and are having to compensate in the higher rpm's by adding duty cycle to make up for a weak pump. Take a look at your fuel map, if duty flattens out after peak torque then your pumps are probably not falling off. I ran a single walbro with my 850/1680 combo. At 6500 rpm I was hitting around 70% duty, but by 9000 rpm I was at 97%. Now I run 2x walbro pumps with a 550/1680 setup with slightly higher fuel pressure. At 6500 rpm I am hitting around the same 70% duty, but at 9000 rpm I am only hitting around 75% duty.

I ran appx 3 kilos static fuel pressure and with 550cc/1680cc at 6000 rpms, my injector duty cycle was around 65-70%~ But at 9k, I was hitting close to 90% so I turned the fuel pressure up and found that at 4.5 kilos fuel pressure, my pumps would lose fuel pressure(2 X stock FD pumps).
Guess I'm going 2 x walboro then.

Couldn't let you have the fastest fc around here for long Your car already looks damn fast, I can't image what this setup will be like

Well I'm going with a half bridge, I was informed that this turbo would work perfect. I've heard of 1.15 p trim T66's choking in the higher rpms on a half bridge, I don't want any choke, just lots of power

Yes I orginally want a T66 w/ a 1.15p trim hotside and was told a much larger turbo/hotside was needed for it....Makes me reconsider... I know a T70 IS friggin HUGE...
