I've been contemplating doing a fuel injection setup and of course I'm debating about the two. What is peoples opinion in this forum?

From what I've "heard and read" lately, FiTech has had and is having issues with their EFI setup. I haven't heard of any "negative" issues with the Holley EFI. The shop I go to for dyno tuning in Lake Havasu sells Holley EFI and likes it, but he may be a little biased because of being a retailer. Do your research for sure. I waas also going to do a Sniper setup on my motor as a test bed.

let us know how the test goes.

There's a gigantic thread on chevelles.com on the Fitech units.

My Fitech works great, and has done for over a year and 11,000 miles including quite a lot of competition... But the Sniper was specifically released to target the Fitech, and seems to equal or slightly beat it on each point. If I was buying today then I'd probably buy the Sniper. Though the Sniper can only support 650hp, that will be plenty for most people. I love my Fitech though.

Any chance you could be convinced to step up to mpfi and not a entry level tbi? They are just so limited. The fact that they rate them in HP says a lot about how basic they are.

What about size and fitment?
Will either fit under a stock 69 hood on a small block?

Thanks

Not sure I agree with that logic, it's just about what injectors are fitted really. Some people have fitted larger injectors, at least to the Fitech.

Either will. They bolt on in place of a carburettor.

Planning on this project for the 69 this winter. Mine has A/C so not much room under hood for mounting components since the MSD takes up the room on the passenger fender well I think I'm going with the Holley system with an in tank pump from Tanks Inc. Since I don't like hose clamps on rubber hoses I'll be using stainless steel flex hosing and AN fittings. Only still in doubt is the fuel filter. Aeroquip seems like the only inline filter housing with a decent filter but another $100+ where will it end. T

I've been doing a small amount of research on the manufactureres web sites. I llke the Fitech unit with the Holley sniper Tank now with the install options but if you go to summit and Jegs you can read the buyers comments. One guy said the Holley injectors were really loud and it had computer problems. Another said the pump up time to load the injectors is 2 seconds once the key is on and he feels it takes forever.Engine masters put a unit on their engine and it wouldnt work on a dual plane and had to go to a single plane. Not sure what heir issue was.



I do like the custom tank. Its only about 250 more than buying just the fuel pump and it comes with a fuel sender gauge and looks to be a good setup for c3s.

I'm still up in the air. I'm leaning to the new holley 3x2 setup just because I always wanted one and I dont need to change any thing other than the intake. My air cleaner setup will obviously need mods as well

I would only go the full route; buying a system that uses 8 individual port mounted fuel injectors because throttle body injectors are little more than a more efficient carburetor.

I'm using the Holley billet filter. It's a nice, quality, product. $68:

Sure, but that's their selling point, they are easier to install than a full system and easier to tune than a carb. They are a compromise.

I've been running the Fitech 600HP unit with their FCC for a year. I've had no major problems and I'm happy so far. Car starts right up and I can drive no matter the outside temp. Its really nice after a long car show in cooler weather to crank and drive away while all the carb guys are working on getting theirs to idle and stay running.

Fitech Customer service has improved and you can talk to a tech right away. From what I've noticed many Fitech problems are caused from poor wiring/installation. Even my FCC operated fine in Georgia summer heat. I did do the FCC modification which drops pump temps and reduces stress on the unit. I did the mod proactively. I never had any heat problems prior or since.

I have no experience with the Sniper so can't comment on it.

fi tech has FiTech easy street efi and the go efi 600 both support the same horsepower but theres a 200 dollar difference. does anyone have any info? Thanks for the input everyone keep it going !

Bigeddie

disregard. The differences (besides the price) are the quality of finish, the ability of the EFI to control ignition timing and an electric fan control.(although in the chart it does say it controls one fan)

Likewise, my Fitech and FCC have been flawless. Only minor drama I've had has been exhaust manifold leaks causing rich running, which is a function of design and will happen with any of these systems. My engine is a grumpy big cam high compression engine, and with the Fitech it is super driveable hot or cold. I've been exceptionally happy with it, and have put 11,000 miles on it in the past 12 months, including a number of competitive events.

Thanks for your response. i recently built my 383 stroker so the 995 unit is what i will be going with.

I recently put a Sniper on my Street Rod and am very pleased with it. I have done setups on FiTech units and my Sniper and prefer the sniper interface. Both units run well when setup properly. I did quite a bit of looking and am very happy with the Sniper.

I would be glad to answer any questions you have on my setup.
