Thumbs up how about vic jr w fast ez efi ?

hey guys just wanted to throw my setup out there to see if anybody has tried it.right now its in pieces while i prep the car(72 camaro) for paint.i will be running an ls3 crate engine w a comp lsr 269(607/621-219/235 at .050,113)vic jr w fast ez efi and 1 7/8 long tubes. the trans is a 2004r w 2200 stall. rear is a 8.5 10 bolt w 3.42 gears. it going to be a cruizer w some suspension and big brakes. how bout it guys, anybody tried that induction set up? oh yea ill be firing it with an msd box. thanks

with that cam why not a composite manifold like an ls6 intake of fast intake? especially if it's gonna be a cruiser? go for the torque IMO

i like the simplicity of the fast self learning system and the look of an old school intake. as far as the cam goes ,it was comps recomendation for my set up. its their most aggressive lobes w a short duration on the intake for vacume on my brakes.

I agree with you on the looks and this is what I would like to do as well.I will be watching this thread closely.
I am concerned that you might run out of induction,meaning you may exceed the power level the EZ will handle.

yea, its gonna be close. fast rates the ez to 550hp. from what ive been able to gather my setup should be in that ballpark. they offer an upgrade to 600hp w higher fuel pressure, but i havent looked into it.

This article had it feeding a 566 HP big block

http://www.hotrod.com/techarticles/e...ion/index.html

Amazing the MPG gain it made on the old 350 Malibu they bolted it to. Have to wonder if the Rochester carb it replaced had seen better days, let along a wideband tune.

Carbs and single plane carb intakes on LS motors usually pick up torque down low and HP up high with only a slight loss in midrange torque. It would be interesting to me to see if that holds true with a throttle body on a carb intake.

yea, im really interested to know, sense ive got all that stuff sittin in my garage waiting for me to get this car put together. it seems one advantage of a carb over injection is the cooling effect of gas in the intake and the advantage of injection is drivablity/tunability. seems the EZ offers both.

I am REALLY interested in seeing how the Fast EZ EFI works out on this project. Most of the problems with carbs that you see posted on here concern stumbles on initial acceleration, especially with the single plane intakes. Usually, they solve it with 50CC pumps or bigger squirters or both. I'm curious to see how the Fast works in the real world and not just slamming it at 3000 RPM on a dyno. I like your choice of cam and transmission and rear gear also. Did you retain a lockup convertor? If you are going to do any thing other than cruise with it, you might eventually decide you want a higher stall speed convertor. Please keep us updated. Ron

im looking to make an honest 400 at the tire with this setup. ill never put a tire on it to hook anyway. i just dont want a new camaro to show me up. i have a hotrod to play with in a 68 camaro (11.30 at 120 on mt drag rads, pump gas, iron heads, flat tappet cam, quiet turbo mufflers.) the only thing is its that old gen 1 stuff. u know adjusting valves, tuning carb , play w the timing. thats fun and all, but i spend more time tuning and less time driving. i want to ride

I like the look of a real carb. You're basically using two components to run the engine . The ez Efi and the Msd box. Make more sense to me to use a standalone harness and gm PCM. And have all the advantages of Hptuners
But that's just IMO

the fast efi is a learning system that adapts to your driving style and setup. im not the sharpest tool in the shed when it comes to electronics . it just makes it EZ for electrical dumbies like me.

With an $1800 price tag, that EZ efi better do it all.

The guys with the later model stuff (anything "newer" than 50yrs, old is late model to me) don't have a problem finding room for the EFI stuff. On the other hand, my problem with either of my street rods...'34 pickup or '34 coupe is that I simply don't have room for the intakes or air ducting for the MAF or even the PCM, unless I mount it in the trunk. The Fast setup would solve a lot of these problems, plus give good starting manners and the idle up for the AC unit. All good things in a car that's mostly street driven but likes to " RIP " occasionally. I'm jus' sayin'....Ron
P.S. One other thing....a lot of street rods and classics are driven on fairly long trips to shows and such and sometimes encounter big changes in elevation, which the Fast adjusts for, I think.

I would do mega squirt. I know some crazy fast LS guys running it. Its only $400 and the software is free. Its a VERY powerfull/capable efi setup.

i think ron and myself are on the same page on this. not looking at building an all out race car. just looking for an old school look, with modern day to day driveability. i cant believe im saying this because ive always been a, bottom of the page cam guy.

How many guys do their own speed density tunes on megasquirt or stock FI? Looks like the FAST unit lets you run without a MAF and it still tunes itself.

And like being said running a MAF results in problems in certain swaps.

If you buy a crate motor the FAST unit might actually be the cheapest way to FI. A carb'd crate motor plus the FAST unit is almost certainly cheaper than a FI crate + ecm + tune. If you don't want to pay a "tuner" everytime you change something, then throw in the cost of a lap top and HPtuners and the fast unit is much cheaper.

So yeah, for a complete pull out sticking with the stock FI is potentially the cheapest route. But then you have all used stuff and still need to figure out tunes with each upgrade.

I wonder if using a wideband gives the FAST unit an advantage over stock FI?
