Ok, so which one of you guys has experience with Holley Dominator EFI ?

#1 Post by wikd69 » Sun Jan 08, 2017 5:57 pm

Hi guys...

I need to talk with somebody who has used a Holley Dominator in an EFI/DIS setup, preferably with a roots build. I'm getting very close to dyno time and would like to fire this new setup in my shop *before* I haul it over to the dyno folks. I need to make sure the damn thing will start, before I waste a day of expensive dyno & tuner time.

My new setup includes:

- Holley Dominator ECU, 8 x SmartCoils (DIS), 16 injectors in 2 Stages ( 8 x 48 lb & 8 x 83 lb )
- Custom dual-sync plate on cam gear with hall-effect sensors for cam sync & crank trigger
- Bullet cam grind - Intake .755 lift / 300 dur @ .050, Exhaust .744 lift / 310 dur @ .050
- 2 x Accufab 4500-2 throttle bodies (4300 combined cfm) on a Kinsler 16 injector top plate
- Hampton 871 blower w/teflon, BDS competition manifold (initially around 10 lbs of boost)

The injectors will be deployed in two stages - the 2nd stage will come in at about 80% duty cycle on the 1st stage, though I only need to setup a single stage for the initial start up. My street tune will be setup for pump gas, the track tune will require 117 race fuel, possibly with some methanol injection added for cooling and detonation control.

There's a lot of potential horsepower & torque with this new setup, but I need to first get it up on idle, and *then* start tailoring the map and configuration for best output.

Anybody out there with experience on this stuff ?

Here's an early shot of the build test fit during assembly...

Good luck with the start up.

We should shoe-horn this into your ride. Just think of all the clashing colors :thumb: :mrgreen:

Actually, that Accufab red would be a nice accent for your paint scheme...

Funny you mention that, because I just learned today that the new design gas valves that we are looking to use on our boilers, are basically a EFI type setup and they come with the mass air flow senor's and whatever else is needed and I said to the guy, so basically this is the same setup as a car, and he said yes.
He asked me if I was familiar with the automotive EFI company called FAST.
I told him I was and he left it at that, so I don't know if they are helping this company design gas valves for boilers or what?
So if I get good at tuning boilers, maybe I should look into doing a EFI setup for the car too???

Yes. You could build the first steam-powered Camaro in the world :mrgreen: :mrgreen:
