I am running RPM Air Gap BBC, it should fit under a stock hood
Nice set up 72406, I know it is has been asked already but is there any chance you can take a measurement of the unit? I would like to know how tall it is, from the base to the mounting edge for the air cleaner.
Cancel that request. I found it on their website, 3 1/4" for anyone interested.
I want to know if a drop base fits. Can I use that, an rpm manifold a flat hood?
Schematic from Fi Tech's website:
EFI will not make more power than a carb.. it is based on tune and size of carb.
Both are fuel at the throttle body.
Ok I have to ask if this mod want make more hp than carb how is it any better as Im building a BBc that wil have 600 hp. Forgive me I am am old school from the 60s. Also was planning on using MSD. So Im wondering how I would be better off with this mod. Let her rip I need to learn. Gary
It is true you can make the same horsepower with the carb but the efi simplifies all the tuning for the lazy guy like myself. No more jet changes, air bleeds, secondary opening stuff. Plug and go. I just prefer the ease of use and it is not so hi tech that the average joe can set it up with ease. I havent dropped the coin for the set up yet but in time I hope to. There are others out there that I am sure work well too. FAST, MSD, Holley, but so far I like the FiTech set up.
Thank You, so it is the same height as a Carb. Just no choke horn which is nice for low profile air cleaners
For a STREET driven car of any size motor EFI will be better than a carburetor because EFI:
-has better cold and hot starting
-does not stumble, can start and drive off right away
-does not flood or stink up the garage
-has consistent throttle response at any engine speed and load
-has an exact air/fuel ratio and can be set for multiple circuits (engine rpm)
-can compensate for altitude immediately
-can compensate for cooler or hotter air intake temperature
-can control timing for various load/rpm/throttle position scenarios
-can produce a stable idle with a big camshaft and STILL offer all of the above!!!
Carburetors when properly dialed in will make the same horsepower (give or take a few %) as EFI and will return the same highway mpg....but cannot consistently offer ALL nine points listed above.
In my opinion that is why EFI is superior to a carb for a street driven car.
I agree, the fuel mileage increase with EFI is predominantly with being optimized at more points than a Carb can be or at least is generally tuned. With enough time and effort and a wideband you can probably get very close to the efficiency level of an EFI system, for an exact moment. Drive up to the top of the mountain and the EFI accounts for it. I don't think I actually argued anything different than you did, just like to talk. haha
