8 Stack Hilborn Style EFI Electronic Fuel Injection

[CaptB]

Has anyone ran the setup with the Hilborn Style EFI?

I have a carbureted BluePrint 347 w/TKX.

Thanks.

Don't know what you mean by Hilborn style? Did you mean stack EFI? I run Borla
149868
This sight always messes up the orientation. :mad:

That is sexy

A friend has Hilborn Stacked EFI for his Gen 3 Coupe. 427w, Holley Dominator ECU. Not run yet but could if he had headers and sidepipes, these need to be built.

Looks spectacular, should make in the upper 500 hp range.

What's listed on ebay is a Speedmaster stack injection setup. I'm running their system, but an older version. Runs like a scalded dog!

I run an 8 stack on my 347 making over 500 HP. I've been able to make it run very well, however I've been tuning aftermarket EFI systems for over 20 years. The real key is what engine management system you use. They are not plug and play as some advertisements would have you believe. There are many horror stories floating around how they don't work well and people ended up taking them back off. Virtually all of these are a result of the wrong electronics and lack of tuning knowledge. The system listed on EBAY is for the hardware only. You still have to buy the electronics, harnesses and fuel system. That will easily add several thousand to the cost. But you can't beat the "cool" factor and they will definitely make horsepower.

Do you have a complete list of what would be required? Recommended parts would be appreciated. I may PM you if I have a question too (if you don't mind).

We run a ton of Borla stack systems and am a dealer for them and the FAST sportsman ECU. Works great and very tunable. Feel free to call me with questions.

The route most people go is to buy a complete system from one of the several vendors. You can piece it together easily enough if you have the knowledge to do so. That approach would not be for a novice. I like the Holley HP or Terminator X electronics (mainly because I've done a bunch of them). You have to choose a distributor that works with EFI. I would probably go with a Holley Dual Sync distributor and matching coil. You will need injectors, sized for your power level, that are compatible with the fuel rails and intake. Then you will need an efi in-tank fuel pump of the correct size, adjustable efi regulator and necessary fuel lines and fittings. Probably some sensors if they are not all included with the electronics. Oh yeh, you'll need an 02 bung welded in the headers, if they don't come with one. I'm sure there are some items I'm forgetting.

I had a Borla with FAST XFI 2.0 Electronics, took a while to understand how to adjust everything, but it ran really well in the end. It was an Aluminum 427 based on the Dart 351 block, dyno'd at 617 ftlb torque and 630 HP. And they do look cool. I did check the specs on the unit you were looking at and it does have a common vacuum chamber in the intake manifold that ties all cylinders together, this is essential so you can run based on Manifold Vacuum, otherwise you can only run an Alpha-N tune which only uses throttle position and RPM to control amount of fuel injected.....OK for a track car but smelly and won't lug well for a street car.
