I read read read - and get no where as most threads get hijacked before there is an answer

for a twin turbo 6l and 8-15#s boost on a progressive controller with #15 meth injection set to come on at 5 lbs boost - what do I need for an injector on my street motor that will likely never see the high side of 6k for rpm - so idle to maybe 6200 rpm

before someone chimes in with go to one of the sizing sites - please dont as I want real world usage

I would like to know what you run on your setup, and what fuel pressure, and how much pulse width you needed to change for idle

Many seem to be using 80# injectors, and meth - but more than a few posts suggest thats not enough but no one has said anywhere that they are running something larger

You'll need to be more specific with your setup to get an accurate comparison. Mainly, turbo size and power goal. Too much variation otherwise.
I run 120's on e85, 52psi at idle, boost referenced. Made 656rwhp at 12 psi. I think I was at about 60% DC at that point, but the pressure wasn't holding due to a faulty pump relay. Fell to high 40's psi.

66mm borg warners 91 a/r is what i am thinking as they are the only non chinese turbo i can afford
800 or so hp would be nice

Buy big the first time because you will need them later when 800 isn't enough anymore

so how big is big and still tunable/streetable - this thing will not see much track time
if i need more hp than 800 - i will go play in my 1600 hp diesel lol

people run 160s on the street with no issues

80lb should get you there, but you also do not state what fuel you intend to use, nor details of your fuel system

1000cc's would cover you well for a pump fuel only car and be no issues with tuning.

And a pair of 66's is probably a bit overkill for only 800hp, but will leave room to grow
