Siemens DEKA Fuel Injector "2400cc" FI114212, how are they at idle and light throttle.

[01txr]

Hi all.

 

Had a injector shop suggest for me to run Siemens DEKA Fuel Injector "2400cc" FI114212.

 

My plans are for street with randon circuit fun and occassional drags.

Focus is more on street response and efficiency then drag. (Its t56 manual so will never be great on strip).

 

Concern is how well these Siemen Deka 2400's idle and light throttle perform.

 

Haltech plug and play ecu.

G35-1050 Garrett turbo

6boost manifold

Plazmaman billet race plenum

Plazmaman pro series intercooler

Head smoothed ports and large ferrea valves

Crow cams stage 3 cams.

Crow valve springs.

Crow lifters.

Arp studs

Ross Forged pistons

Argo Rods 

Ross Metal Jacket Balancer

Atomic girdle

Atomic billet pump gears

Billet oil pump backing plate

Timing Chain undecided atm

Process West billet twin pump surge tank

Etc, etc

 

Goal, ultimate street and circuit efficiency.

Possible may run e85 at a later point.

 

Will I even need such a high flowing injector?

 

Feedback on injector selection.

Feedback on Haltech ecu controlling the injectors.

Feedback on e85 and using flex with the haltech.

All feedback will be greatly appreciated.

I think they might be a tad big for what you want.

 

I've got a 2200cc injector at 4 bar and it was using 60% duty cycle at 40psi boost, 685awkw/918awhp and on e85.

 

A 1300cc injector might be better for you as it will be able to idle and drive properly on 98 fuel, while still providing enough fuel for 650rwkw or so on e85.

I was thinking of the Bosch 1600 from Goleby's.

If your only at 60% duty cycle at that power on 2200cc then theres no way I would require the 2400cc deka's.

 

Have no idea why the efi shop would recommend the deka 2400's.

Also considering he said they will be $350 each when they get stock.

 

I liked how great my Deka 660cc worked on my last setup, could idle engine down to a silk smooth 400rpm (set it at 600), could hardly tell it was running.

 

So it would be great to have a injector that will idle nicely but support its setup power potential.
