Hi all,

I was hoping to get a EFi system and I wanted to hear people's opinion on which is better Fittech or Holley Sniper EFI?

Thanks

Mike

I don't have either, but from what I have read, and the people I have spoken with I would go Holley. Seems the fitech has some issues and they don't have much support.

I haven't used the Holley system but have heard they are better than the FiTech. I'd try a Super Sniper if I was going to do a TBI system.
I have the FiTech Go8 1200HP system and it has been working good for me, but the instructions are not that good. The FiTech "command center" fuel pump/surge tank setup seems to be a problem from what is posted on the FiTech facebook users group. Any EFI is going to need a good fuel system to supply the EFI Unit. I'm not sure if Holley supplies fuel filters with their kit? The FiTech does not come with fuel filters, so you need a good filter.

I also depends what you expect from the EFI system.
Some like a more 'open' system where you can add stuff later on and thinker with more.

Look into the MSD Atomic setup as well. I have one but have not used it on the street yet. I have it running on a 340 on a test stand and out of the box I was able to fire up the engine and break it in with no problems.
Its a nice basic setup and it will control timing and can trigger fans, etc.
Whatever you decide to get, do not skimp on the fuel pump setup. If you dont get a good pump your pissing in the wind with any brand FI.

Thanks all. I planned on using the electric pump that comes with the EFI set up. My hope is to have a good working system that starts right away, self tunes itself and doesn’t vapor lock

I'm in the process of installing a Super Sniper on my '65 Coronet. It is a simple system but it still takes a little bit of work to make all of the changes to the fuel system as well as the wiring. You might want to read over the instructions a few times before you buy the kit so you're prepared with all of the parts you need.

I think what they are telling you is to budget an extra grand for a functional fuel delivery system. Because I can tell you that just putting the included pump in place of the original mechanical pump will not work well.

There are many ways to do it but the labor/cost ratio depends on your skill set and/or check book.

Good to know!

How would people do the plumbing for a job like this with a car that had a mechanical fuel pump? I run a standard 3/8' line with a return line.

Here is a great deal on the Spectra CR9AFI EFI fuel tank with pump and sending unit for $257.66

I think the pump is a 255 lph walbro? Should be good for around 500+ HP

The Tanks Inc Tank is $245 tank only, but you can select different fuel pump modules if you need a larger pump. The 255 LPH pump module is $220.
Sending unit is an additional $35.

I would use two 3/8" steel lines, one supply, one return. Likely re-shape then to come up closer to the firewall and install -6AN adaptors to the hard line and then -6AN hose from the hard line adaptors to the EFI fuel rails.

Simple to describe. Mount the electric fuel pump as close to the gas tank as you can. In the gas tank is even better.

Disconnect the mechanical fuel pump and install a blockoff plate.

Connect the frame fuel line to the engine fuel line. Connect the return line to the regulator return port if it has one.

Figure out where to get power for the fuel pump.. you need enough amps to run the pump and the power has to be switched with the ignition. Consider hiding a switch in the power line as an antitheft device.

I also have the Go8 1200 hp system on a 543. I am working through it but all I am going to say is the same thing the shop told me when I picked it up. "Good Luck"

The shop I use has gone above and beyond trying to get it right. They aren't Fuel Injection experts but they are very very good mechanics and can make a carbed car run right.

This is starting to sound ominous, like I am steering on a straight a head course for the Bermuda triangle of fuel!!

Just installed a Sniper EFI on my 512 stroker a couple weeks ago. There really isn't any aftermarket support for my car in the way of EFI gas tanks, so I ordered the Master Kit which included in the fuel pump and other goodies. Mounted the pump and filters to a piece of aluminum stock that in turned got mounted in front of the tank using the strap bolts. New 3/8" nickle-copper return and supply lines also ran. Had to modify my sender for 3/8" pickup as well using bulkhead connectors.

It's a bit more involved wiring wise than what the marketing leads you to believe, but it worked out great. On the first startup it was pig rich until it got warmed up enough to trigger learning mode. After that and a few miles the A/F ratio was where it needed to be. Startups are instantaneous and I gained quite a bit of power overall (that last bit probably has more to do with the fact the carb was undersized and the fuel lines were replaced). Didn't do anything tuning wise yet aside from answer the initial questions on the handheld.

The Master Kit was $1250, tubing for the feed/return was $120 and add another $300 for fittings and other material.

Did FiTech with Spectra tank, most economical solution I could find.
Used my 5/16" fuel line as the return and added a 3/8" fuel line.

Spectra is an all in one solution and much cheaper than Tanks where you have to buy everything separate.

Add to that venting the Spectra tank is much easier. If you have your OEM vapor seperator you sre golden.

I have FiTech on my 451 stroker ( the Holley wasn't available yet). I used the Aeromotive Phantom fuel pump, and used new 3/8 hard line and black braided line to make new fuel lines. I think I have about $1600 in the whole set up, including buying a new fuel tank. That said, the Phantom pump is great. The FiTech still needs some tweaking. I don't have many miles on it yet, so perhaps it needs to keep learning, but so far I can't say it infinitely better than the carb I was running. Starting is about the same. Cold accelerating is way better than the carb, but once the engine is warmed up I can't tell a big difference. I will continue to tweak it, but as of now, I can't honestly say that I would do the fuel injection again. The Phantom pump, however, is awesome.

I got the phantom 340 fuel pump. Great pump and installs easily in a stock tank.

Fitech on My 440 with an Aeromotive in tank pump, 3/8 feed 5/16 return line.

On this system the white wire has to have keyed on power. I used diode near the ballast resistor to achieve this. I rushed this part and it is not very pretty.

Hey AndyF, perhaps you could design a simple, attractive plug-n-play diode setup for this application.
