Ok i currently have a Comptec Supercharged S2000 f20c. my before and after

Before:
Non aftercooled 5.5psi
Emanage Ultimate

After:
8psi pulley
UR FMIC


so my question is what size injectors would work best with the PSI and the emanage ultimate?

 

750cc's would be good.

 

Netting 8psi? Or putting on a 4" 8psi pulley? becuase the two are very different when you put an fmic into the equation. Its possible you could net the same 5psi you were before just from the added boost loss, if not more. In that case you wont be needing bigger injectors. 750cc injectors are good to about 450whp, so a bit overkill. You likely will suffer from a lesser idle/partial throttle operation with an E manage and those size injectors, vs a smaller injector that has better fuel atomization at less duty. With a 3.2" 12psi pulley) you will net 9-10psi average with an fmic. 550cc injectors would suite your needs just fine I think, 650's maybe if you want to go for a 3" pulley.

It is important I think to to run an injector that is a good match for the set up to better get a full operating range quality vs just get the biggest injector you can find and call it great.

 

I got some RC 550's if you are ineterested.. PM me.

 

You should pick up chad86's 550 injectors, they would be perfect for your setup. You will lose boost with the fmic like s2000junky said.

 

used 550's @9.5psi pretty much maxxed out
im using 670's now at 12psi

 

i have a set of rc 650s used for only a few dyno runs. They look brand new. They would be good for your set up. PM me If you are intersted. As s2sexy said, you will run out of 550s very quikly. These should be just right.

 

id725 or id1000

id1000 and you can get e85 tune down the road with plenty of injector. i have 650's now and will be goin to id1000 in future.

 

I have done a shnit ton of research and I went with the Injector Dynamics 725cc injectors. Not only is their website more than educational to the operation of their injectors. The 725cc will allow you to move up in boost as you please. You know you wont be satisfied with 8lbs. So when you go to 10lbs of boost you will be set up for it.

Not to mention that ID offers OBD2 clips for plug and play capabilities. Keeps the engine bay looking clean and helps if you want to go back to stock.

Cheers!

I cant wait for more e85 stations to pop up.
