Does anyone know someone local that can help with the setups for the F.A.S.T. fuel injection systems.

Thanks,
Russ

help with install, or help tuning? The only person i know thats installed the speed-pro is gabe (youl luz), but hes in sac

outwest: Whats your combo? If you have a 5.0(86-93) the install is so easy a monkey could do it.. If you have a 4.6, OH MY GOD ITS A BITCH !!!!!!!!!!!!!!!!!!!!!

Keith at forced fed performance in Yuba City can probably help you with install and tuning.

http://www.forcedairmotorsports.com/

Also Fodge engineering in Sacramento and Wizard racing in Woodland are people that you should contact.

If its not too hard I can probably answer any questions that you may have.

stay clear of Forced Fed performance. They gave me the run around for months.. IF its not a straight swap in kit, they have no idea how to do it .. I also went to Fodge engineering and they never even got back to me on how much it would cost .. After all the wait I just decided to do it myself.. Glad I did because they way I did it you cant even see any of the wires and ALL the factory gauges still work.. Thats a VERY hard thing to do on 96+ cars. Hell even my cruise control still works.

That's weird about Force Fed. My 67 stang was not a straight swap and my friends 67 nova was not either, but Keith was able to help with both of our combos! And Fodge is Fodge!! Craig at F.A.S.T recommends him and Wizard Racing over anybody in the Greater Bay Area. If you can get Fodge he can do good things on the Dyno. Made over 1000hp in my combo and around 1300 on my friends. I think his name is Theo(never met him but was referred) at Wizard. He has a real fast car in the PSCA that is a top contender.

I know this system you guys are talking about replaces mass air, but how exactly is it different and how is it better than mass air? Oh yeah, and what is the cost for it? Thanks.

I have 331 with a novi making 25lbs. intercooled, backed with a c4. the install is done i am looking for some help with the tune or someone to ask question to see what has worked and what has not. thanks for all the replies.

If they calculated weight, it would be called a weigh air meter instead of a mass air meter. Mass and weight are two different things as I'm sure you know

Mass and Weight

Before we get into the subject of gravity and how it acts, it's important to understand the difference between weight and mass.

We often use the terms "mass" and "weight" interchangeably in our daily speech, but to an astronomer or a physicist they are completely different things. The mass of a body is a measure of how much matter it contains. An object with mass has a quality called inertia. If you shake an object like a stone in your hand, you would notice that it takes a push to get it moving, and another push to stop it again. If the stone is at rest, it wants to remain at rest. Once you've got it moving, it wants to stay moving. This quality or "sluggishness" of matter is its inertia. Mass is a measure of how much inertia an object displays.

Weight is an entirely different thing. Every object in the universe with mass attracts every other object with mass. The amount of attraction depends on the size of the masses and how far apart they are. For everyday-sized objects, this gravitational pull is vanishingly small, but the pull between a very large object, like the Earth, and another object, like you, can be easily measured. How? All you have to do is stand on a scale! Scales measure the force of attraction between you and the Earth. This force of attraction between you and the Earth (or any other planet) is called your weight.

If you are in a spaceship far between the stars and you put a scale underneath you, the scale would read zero. Your weight is zero. You are weightless. There is an anvil floating next to you. It's also weightless. Are you or the anvil mass-less? Absolutely not. If you grabbed the anvil and tried to shake it, you would have to push it to get it going and pull it to get it to stop. It still has inertia, and hence mass, yet it has no weight. See the difference?

I hope others learned something from this as well?

Lets look at it this way:

The MAF transfer function is not in CFM, its in weight.

X Value: A/D Counts or Voltage
Min: 0 A/D or 0 volts
Max: 1023 A/D or 4.9999 volts

Y Value: Air mass in Kg/hr or lbs/tic


Weight and Mass(since we are not astronomers or a physicists off the earth)

"What's the difference between weight and mass?
As long as you stay on Earth, the difference is more philosophical than practical.
But if you stay on Earth, gravity is always the same, so it really doesn't matter whether you talk about weight or mass.
If you talk about the mass of an atom-you're always talking about the same thing; if you talk about its weight, what you mean depends on where the atom is. "

Mass and weight are measured with the same units The MAF transfer function is like I said in my first post on this topic:

aka Kg/Hr (Kilograms per Hour)

I've said everything I've wanted to say on the topic... the original poster can take from it what he wants

I am no expert at tuning the FAST system, though my car seems to run pretty good on track as well as driving around on the street. If I could have my choice of FAST tuners it would be Jim Summers, but he isn't about to come out to CA. He has given me a ton of information and tips about tuning (I bought my setup from him) with the FAST setup but I don't think I would put myself in a position to have any of the people mentioned do my tuning. To each his own I guess.

so, to lose weight, i need only move to a different planet...

that's good, cuz i'm very heavy
what's a ticket to pluto cost these days?

j/k

Hey Rob, this web page should help you decide what planet you want to move to so you can lose weight:

http://www.exploratorium.edu/ronh/weight/

Pluto is a good choice.... nice and cold... no need for an inter/aftercooler!

Posted by John91coupe (Member # 18) on :
 
Actually, you don't need to go all the way to Pluto, it's a REALLY long trip. The Moon will give you about the same gravity and is just as cold, something like 360 deg F below zero. Gonna need some very heavy clothing though

As far as relevance to mass from weight is invloved, none of the interluded statements that previously were presented contain any relevance to the forth coming.

Mass equations in the mass of the world is non linear once weight is added. Weight non-perpetulates mass as a coexsisting substance, dependant on each other. Plight, brought together from merging at an equilibrium presence does not necessarily bring one or the other more relevant to the formula of m/w=2xm3.

You might want to look into a EPEC. they are very to use. I use a FJO wide band for A/F feedback. I put the hole set up together for less than 1500.00 you can find a copy of the software on the web to see if you like it.
