I am either getting a stage 2 from floor it or a darkside stage 4 soon. Just wondering if those pumps would fuel enough for those injectors? Also how are these injectors for daily driving and will I be able to keep the egst cool enough with a 66 charger?

Everything ive read says the stage 2 from floor it will only handle 3.5's MAX. 3.3's is what Don recommends max on the stage 2.

I ran 3.3 on a Floor It Stage 2 and did fine. To be honest with a big pressure box I would see over 27000 psi rail pressure when I got on it hard.

what does the cost of a stage 2 cp3 cost from floor it?

RamNu2

Roughly 1000 or less is what I was told when I had mine put on friday.

Billm2004

1000 installed or just for the part?

Just for the work done on the part if you supply a good core.

I was told 3.3's with a stg 2 Floor it cp3 with my combo would net me 600-650hp any day of the week

I run flux 3.3s also and the pump keeps up fine on the street no issues. the only issues I see is setting still if you rev it up is the only cut out I have ever seen from it. with a 66 charger and a manual truck you might be ok. I have an automatic truck and bigger than a 66 turbo and the truck still gets to hot. I was told by bobby at darkside you have to have 45psi of fuel pressure to keep up with his stage 4 but you may already know that. all those 250 gph fuel systems arent cheap at all, ive been pricing them. I was told the largest injector I could run was the flux 3.3 with a stage 2 pump so thats what I got.

I would stick to a Flux 3 or smaller if you stack electronics...

Flux 3.3's and a big Smarty program was ALL my Stage 2 could handle.

i'm running a FASS 150/200. set at 50psi, it flows 180gph, and this pump loves it.
it would pull the 150/150 down from 20 to 6 psi.
I'm not sure what John's pump requires for inlet pressure/volume.
I've been reading up on Don's injectors quite a bit these last couple days, i would say it depends how much you want to rely on your electronics.

I want to make some changes in the future im not sure what im doing yet. either have the pump worked on or add one to it. I dont know what will lay down the most power and be the most dependable

how about adding a modded pump over your stage 2...just some food for thought. i will try to get down to indy either this weekend or next to meet up with you if you arent busy.
we may end up in jail, itll be fun though

im on the EPA's most wanted list now.

I run 28 psi from my lowley Walbro GDP set up...does not budge more than 2 psi...even when the rail can't keep up. Even at WOT with only 12,000 psi!

A 250 gallon/hr lift pump will not help that...

There is plenty of room with w/ electronics to make up for slighley smaller injectors. Don't over do it with a single pump or you will be handycapped trying to tune electronically. I just installed Flux Mileage injectors (smaller than stock) that made 70 hp with 150 hp of electronics turned on!

I bet Flux 2's would make 150 hp no problem on a big Smarty program w/ a little pressure added.

I think ive gotta work but we can get together sometime. I have a buddy that got a letter in the mail from someone stating he had a pollution problem with his truck. one of the few times I actually raced someone I got pulled over and the cop complained more to me on the smoke and not the speed. .
im thinking pretty hard about adding another pump to what I have when im not broke
