Bolt on retrofit EFI with adaptive learning
« on: June 02, 2007 - 07:03:46 AM »
If it does what it says it will be a nice system.  The installation instructions sure look easy.

The Boss EFI is what performance car enthusiasts have dreamed about for a long time, a true bolt-on 4-barrel carb-style retrofit EFI. The vehicle still looks like it has a 4-barrel carb with no fuel tank return lines, fuel rails, or other giveaways that this vehicle is packing EFI. Now classic Musclecar enthusiasts, Street Rodders, Pro Touring cars, G-Machines, Off-Roaders and anyone else who wants the clean single 4-barrel look and performance of EFI can have it at a reasonable price.

looks pretty cool, price is not too bad for a wideband equipped system even if it is a basic throttle body injection.
The coolest would be the dual quad setup, but it better not double the price!

Mopar Muscle did an article about this a couple months ago, using mass-flo EFI. The article stated that this system was by far the easiest and simplest to install, and it delivered awesome results in the areas of horsepower, throttle response, and all-around driveability. www.mass-floefi.com.

Umm, $3750 for a Ford EEC-IV based injection system???? (Chrysler Big Block -- $3750 mass-flo EFI)  :eek7:
not saying its a bad system, just seems steep for a bunch of 5.0L ford stuff (minus the manifold of course)

I just dont get the high price of fuel injection. Why would I get a fuel injection kit when for the same money I can get a accessory style supercharger? Smooth starting/idle or 50% additional power, not much of brain teaser there.

Depending on how savvy a person is, you could do fuel injection for under 2 grand if you know what stock parts you can use and so on, on a small block maybe less. If you base everything on mustang 5.0L stuff, parts are super cheap because there are thousands out there  :ebay: As far as EFI vs. carb, I think it is more personal preference than anything. There are advantages and drawbacks to both. I am doing EFI on mine because I am more comfortable with it now and (for me) it is more flexible with what I want to do with the car in the future.

Don't get me wrong, I would love to have efi on my car. You cannot beat it imo, I just hate the fact that it is still so high for a kit. They have most of us by the short hairs because we either lack the knowledge to put together a DIY system or we lack the time and patience to mess with it. I feel there is no reason we cannot have a comprehensive kit all inclusive that cost somewhere around a grand, 1500 tops.

From an e-mail by them:


Thank you for your interest in the all-new RetroTek BossEFI system. The
story in Hot Rod magazine came out a little early and our site was not ready
to go up so we will be adding info daily.

PRICING
To answer some basic questions, the system is set to target the $2000.00
price range for the 930cfm body and comes as a complete package. The
Throttle body bolts in place of a Holley or similar 4 barrel and has the
same overall dimensions, so the air cleaner will remain in the same
location.

SELF-TUNING COMPUTER
The computer is the first self-tuning system available and is a speed
density ,closed loop system . We use a PLX wide band (included) and the
system delivers hands free tuning at all loads and RPM²s. The key to our
system is its VE SYNC which reads the air fuel of your engine and re-writes
the base fuel table to deliver the exact Target Air Fuel ratio desired for
your engine. This can be done while viewing the info on a laptop, or without
one. The system re-programs itself so the oxygen sensor does not have to
work to correct an inaccurate calibration each time you run your engine.
Once this is done you can leaved the O2 in place to compensate for various
fuel and elevation differences. A video demonstrating a system being tuned
will be posted on the site shortly so keep checking it out.

ADDITIONAL COMPONENTS
The kit comes with a high pressure fuel pump that mounts on the chassis at
or below the fuel tank . For over 500HP and larger applications, an
ultra-high performance pump is required for an additional charge. Also there
is no need for a return fuel line although one may be used along with an EFI
bypass regulator. The return-less system is included in the kit but the
bypass style system is not included and can be purchased separately.

ECU & WIRING DETAILS
The computers dimensions are 6-inches long, 4.5-inches wide, and 1.65-inches
high; and it can be mounted either under the dash or in another dry
location. All wiring features weather pack connectors and are completely
terminated although you are required to install an o2 sensor bung in the
exhaust pipe. This can be done in one side only by any muffler shop and the
bung is included.

SYSTEMS AVAILABLE
There BossEFI comes in 2 sizes, 930 & 1200 cfm ratings. The 930 will handle
up to 650hp and the 1200 is good for 900+hp with the correct size injectors.
There is a simple formula to size the injectors. We use 4 so the math is:

HP divided by 2 /4 = injector size.

The computer is capable of very small pulse widths so it is better to be a
little large in this area. An example of this is 500hp/2/4 = 62.5lbs. In this
case we would use 63 lb injectors.For Dual Quad systems we would have 8 injectors so HP/2/8= injector size. 500hp/2=250/8=31.25. We would supply 8 32lb injectors in the kit. You can use this simple math to work up any HP combo you have. This is a Quick tip only,call us if you are un sure. All necessary sensors are included so
this is a true bolt on system!!

RELEASE DATE & FURTHER INFO
We will be sending out periodic emails with more details about the BossEFI
system up to the Spring 2007 release date. Please stay tuned, as THE MOST
EXCITING NEW PERFORMANCE PRODUCT IN 20 YEARS is about to REVOLUTIONIZE your
vehicle.

Thanks for your interest,
RetroTek Speed

There is a thread on here from a few years ago where a guy put a Ford 5.0 EFI system on his 72 Cuda. He modfied his manifold for the injectors and claimed to have it all tweeked out. I think his estimate was under $1K in parts?

I tried to contact that guy with the 72 when I originally was going to use the 5.0L ford stuff on my car, but he never responded. I had pretty much everything to do it and I probably would have been into everything including an EEC-Tuner for about 1500. I only went to megasquirt because of the features that the EEC-IV based system wasn't capable of without major modifications. I had no problem selling the EEC-IV stuff on ebay, pretty much made all my money back too.
