Need help choosing the right size fuel injector? Ask in here
Current setup on my 04 evo 8:
evo 9 turbo
Tomei 270 procams
Kiggly beehive springs
Shearer o2 dump
BR fmic
BR uicp/licp
BR small battery setup
BR TBE
walbro 255
hallman pro rx mbc
tial qr bov
comp stage 3.5 clutch
fortune auto 500 coilovers
Dynoed on MD 363whp/364wtq @25psi with parts listed above
I will be installing:
FP black DBB
FIC 1250cc
Full Race stock replacement manifold
Shep trans ultimate ratio, 4.11 FD
Spoolinup COP
With the addition of these parts, how much will the 1250's get me with a modded 255 on 93 and E85? I am wondering if I went too small on injectors with the turbo. Thanks in advance.

I have similar mods. Curious to know what injectors you would recommend for making this hp also on MD BUT on California 91 octane.
'06 Evo IX
Currently on car:
ETS FMIC and Pipes
Works o2 housing
Works 3" dp and exhaust
Wally 255 (unmodified)
Plans:
FP Green Journal
XXXX CC injectors <- this is where you come in
Speed density conversion
ported intake manifold, exhaust manifold and 65mm tb
Im going to put a map switch on it for pump and e85.
Do I need high or low imp injectors and what size for 450whp on a mustang dyno?
Thanks!

My goal is making 400/400 on my evo 9 with stock turbo.
The current mods are:
ETS 3.5" FMIC and ETS LICP&UICP
Grimspeed EBCS
GSC S2 cams with GSC beehive valvesprings and Ti-retainer
APR headstuds
walbro 255
DC downpipes w/o cat
Greddy 3" exhaust.
What size and what impedance injectors will make ~400wtq/~400whp?
I am also thinking of getting O2 housing and Spoolinup COP, and would these mods get me more power?
Thank you

you need to add a bigger pump before you can max the 1100cc out on e85. but the 1100cc is going to take you to roughly 550-570WHP dynojet.
1450cc would work. pm me if you need injectors. otherwise you're good to use what you have after a br double pumper. i also sell that also
i been selling a lot of 1450cc to customers who want room to grow and they work well on both 93 and e85.

dont need a map switch either. tephra roms have it built in to switch either via TPS or intercooler switch.

OT, but I slways wondered whether the only difference on the two Scott Frazho runs in your sig is speed density vs MAF. Can the 6mph trap speed difference be attributed to just swapping from MAF to SD. Is the SD alone worth 6mph on the stock ECU?
either or. just make sure you get a 1000cc+ injector and you're more then fine. but a single walbro (modified) won't cut 450whp on a proper reading mustang on e85. unmodified no chance in hell. 
dont need a map switch either. tephra roms have it built in to switch either via TPS or intercooler switch.

So you can tune to map switch off TPS/IC switch?
Is there any way to wire in an e85 sensor into the stock ecu?

i run GM sensor in my car and then use a gauge from dynosty to read my %.
i would stick to logging it only. yes you sure can in tephra mod.
Ok Ill have to do some searching on where to wire one into. If its too hard Ill just do two separate maps. One pump gas and one e85 and tune each as so.
Ill try and get some FIC 1450's.
BTW also sent you a pm.

id go with minimal 1250cc and a big fuel pump. on paper 450lph walbro should do it easy on 93 rewired. if you want to be overkill then 1450cc.
pm me if you need anymore help.
