Alright guys looking for some more power for next year 2018

my current set is id1000
gtx3076
Fbm 340
Aen v2
stock fuel line with e85

91 tune at 12 psi at 388whp
e 85 tune at 14 psi 425whp

What injectors should I get to max out my setup without opening the engine block.

my tuner at import auto pros said go 1600 five 0 injectors

any suggestions? Isn't the most u can get put if the gtx3076 is around 19psi at 550whp? 2200 injectors?

 

larger injectors are a must. once you start getting close to 500whp you'll probably need a return fuel line installed to keep a steady fuel pressure. but that should be it. larger injectors and a fuel return system.

 

My 2005 ap2 has fuel return already should I consider an aftermarket one?

 

oh no, thought you were 06up. Youre good then, jist need to upgrade injectors

 

I don't have any experience with injectors any larger than 1300s but every tuner I have talked to said If I wanted stock-like idle don't go larger than ID1300s....So I have ID1300s lol. How much power you make depends on how aggressive your tune is. ID1000s can net 550hp...

 

I want to get there without adjusting fuel pump as I have fbm340.. just curious to see what who I'll get maxing out my current setup... I'd be happy with 20 psi e85 at 588whp. Using the whp to hp guestimate which equates to 720hp.. isn't the gtx3076 efficient up to 550whp tho?

 

get the 1600 or 2000cc, Walbro 450 and send it

 

I'm wanting wanting to stick with fbm340. So 1600 or 2200?

 

I had the old ID 1600 injectors and they idled just fine. The 2000’s idled not great on E85 and horrible on pump. You can make 560-580whp on E85?at 60psi base pressure but you will need 1600 If you want some room for duty cycle at 600whp. I would get the Walbro 450 and stick with 560whp+ its more than enough for the street

 

I've personally only ran ID1000cc personally, great injector, and no complaints
I know people who've run ID2000 or any 2000cc+ injector on E85 and their cars ran great
1600 idk but if the price is pretty close and driveabilty about the same, why not just go 2000cc
