Fuel injection Holley Vs Fast
01/20/12 at 18:35:15

Ok guys, i am trying to decide who to go with for Fuel injection, I started off looking at FAST, and their system is tried tested and true, i know people that are running their system, and love it! However the New Holley Dominator is more recent to the scene, so i am a little more aprehansive about a new system, but the price sure is enticing.

Does anyone have any prefrence to either system? Maybe tried both and has some feedback? Please post whatever you know to help make my decision easier.

Keep in mind this will be a turbocharged application.

Well I must say I've become more impressed with FAST flexibility , to used either as a throttle body or multiport system. I had a Edelbrock Pro Flow 1 system and loved it. By the time you add a distributor and an intake to the Fast setup you get with the Edelbrock setup, the Edelbrock setup is actually cheaper. But for use with a turbo set up this matters less then then Fast's flexibility. The Holley system is pretty much a glorified throttle body set up and a turbo set up you need though 8 injectors to make sure no cylinder go lean. LRDaum

Ok i guess i should clarify the setup i am working on currently is a 6.0L chevy LS motor, going twin turbo, the Dominator system controlls the 8 injectors, uses the factory multiport intake manifold, or you can use one of their custom multiport intake manifolds. In essence both the Fast and the Holley go about their functionality and use of factory parts in similar ways, but i was curious if anyone has any feedback either good or bad regarding each system. From my research the Fast system is coming in at $4950 and the Holley for similar function is coming in at $2300. Generally when i see a price difference this great i get hesitant on quality, drivability, reliability, controll etc.

Go with the Holley.
I have worked with quite a few fuel injection systems, and the Holleys self learn is the best I have ever seen.
There are a few runnng the Dominator system with turbos on the LS and love it.
The data acquisition on the Holley is right up there with a Race Pak system. And comes built in on the Holley.
My car has been 9.35, it starts and drives around the pits like a new car.

Once again I can not say enough about the closed loop works.

I understand that would eliminate the A/F ratio variance between cylinders? SKeown

$1500 for the base Holley setup, $2300 for the Dominator
You will need a intake, or add bungs to yours
Probably 50-60 pound per hour injectors and a throttle body (could mod a carb for the job)
Fuel pump
A Laptop
And fly me out to set it all up Grin
