SBC replacement - FI or Carb?

[V8Dom]

may i ask cost.. and what hp iy will support?

As a result of my move to 600bhp plus. I am installing a complete FAST XFI2 system with individual cylinder coils etc. This I managed to pick up cheap having been used for 1 dyno session only. This has the ultimate flexibility and will run anything up to boosted dragster power levels. It also has a function that is semi self learning.
As a result my complete EZEFI system is available to any body who wants EFI but is <550hp SBC. This works perfectly with MSD ignition and coil systems but I also have an electromotive fully programable wasted spark system with 4 large ignition coils to get rid of the dizzy system as well.

any reason you opted for this rather than the holley system that goes to 1200 hp too?

Would never consider anything but FAST.
The amount of power that an EFI system can manage is a function of the injector sizes (assuming the fuel pump can keep up) all these quoted powers are simply with the supplied injectors. However having massive injectors that can handle way more power than you have causes big problems at low power/rpm as the on pulse cannot be short enough to supply the correct amount of fuel.

I will be pressing the button on my refresh soon. Although it likely to cost £8k to 10k with CD it's a lot cheaper than the £24k quoted by autobionics to swap my sbc with a ls engine.

Mark
is your fast system, with new inlet and 8 direct port injectors

I have both the straight carb replacement and a manifold with 8 injectors and air only throttle body.

Do they not have a sixteen injector system to share the duty for high and low flow requirements?

Indeed but mostly used for nitrous and dragsters I think.
