I finally got one of those Edelbrock intakesand a set of fuel rails that I've seen on their website.Now I've got to sta the yard sales up to get the rest of the parts (hehe). This intake is based on the torker II part # 50565an the fuel rails are #3637. They have two other intakes to choose from.

GOOD GOD! That picture is huge. Sorry guys. lmao

[Hammered]

I'll be picking mine up this Sunday from Summit. What's the front-to-back offset between the left and right fuel rails? I'm trying to finalize the design of my fuel system.

Not sure what you mean there but. Here is another picture but smaller.LMAO

[Fullhouse]

I finally figured how to resize the pics lmao. So here is the first picture resized.

[Skip Fix]

How high are the fuel rails compared to carb/TB base?

[Skip Fix]

I looked clser and no exhaust crossover??

[Bulldog]

(Immitation of Butthead) This is the kewlest thing I have ever seen, we're finally going to score!!!!!

[Donovan]

Does this new setup come with it's own throttle cable adapter or bracket? It was unavoidable that the original pad got wacked since it was on the runner where the injector goes. I see the inner one is still there.

Just one of the things that I really wanted to see how they resolve it.

[krisr]

How much?

[68convertibles]

really...HOW MUCH AND WERE DID YOU BUY IT FROM?
ALSO IS EVERYTHING THERE TO JUST HOOK IT UP AND YOUR DONE?

[Fake Goat]

Weren't they coming out with a complete system and not just the intake/fuel rail combo? Maybe that is what is supposed to be released by the end of the year.

I just ordered one from Summit on line. I went to edelbrocks web site and got the part #. went to summits site and put an "edl" in front of the part # and it worked. For example, edl-29575 in the search box brought up the Victor EFI manifold with standard 4150 mount. It cost $380.69. I also ordered their fuel rails Edl-3634 $81.69. Both parts are back ordered til 11/10/04. I think the torkerII version is about $100 cheaper.
Skip, don't need a crossover with port fuel injection. The injectors do all of the atomization. Some systems(ford)use coolant to the throttle boby to prevent ice up on really cold days.
I dont think their complete system will be out for a while. There are alot of companies that can hook you up. Kinsler, Fast, Accel just to name a few. <span class="ev_code_RED">WARNING</span> Fuel injection can and will cost thousands of dollars. Like $3-4 when all is done. Some guys have come up with set ups to retrofit older FI systems to work on other cars. That may be ok for a stock type motor. Not real good for high performance use. Hope this helps.

[Trips4me]

Not knowing much about FI could someone please explain to me how this system works?? It looks like a standard carb intake with fuel runners attached but I have no idea how this is supposed to work? Thanks for answering a dumb question.... Jim

Awsome. Is a F.A.S.T. system the way to go with this? Who makes a throttle body for it? Any suggestions?

[Steve C.]

These article will be of interest:

Also the fuel system needs to be revised for fuel injection. More pressure, return line, etc.

Jim, the throttle body will allow the air in while a computer figures the amount of fuel to add. The figuring part is where there are a few options avalable but the air must be measured or calculated some way. Thats where a variety of sensors come in, but it's worth it, I'm real impressed with my LT1. I never came accross carbed SBC's that ran like this when I had my '69 bird.

[Steve C.]

Wilson makes a 4150 style throttle body that is rated at 1136 cfm.
Reportably it is one of the shortest, not as tall as the carb. and manifold together.
If interested look in the article I mentioned above it shows height comparisions.

Morning Jim, I'll take a stab at it!

There are currently two major styles of FI: TBI & Port.

TBI is Throttle Body Injection whereby the carburator is exchanged for a Throttle Body similar in appearance to a carb, with injectors (usually 2 or 4) inside the venturis of the Throttle Body. While an improvement over carburation, still suffers from "pooling" and other carb style problems. Manifold selection is very similar to carb. manifold selection, ie: dual plane is best for street. No, or virtually no changes needed to manifold.

Port FI: Port FI is currently the hot ticket. Port FI uses 8 (or more) individual injectors mounted close to the intake port. On a V-8, typically there are two fuel rails feeding the injectors on each respective bank of cylinders.
Having the fuel introduced close to the intake port eliminates "carb style" problems such as pooling and enables the user greater freedom in manifold selection. In other words, it's possible with a port system to use a single plane manifold (such as the Torker II) on the streed without ill manners as all it's doing is conveying air.. not air and fuel. The intake manifold must be modified to accept fuel injector bungs, and fuel rails. What isn't shown (and is the expensive part) of the FI setup, is the Throttle body, MAF or Speed Density sensor, Computer, Fuel system (carb system is totally inadequate for FI.)

I'm leaving a lot out here, but you get the idea.

From a $ point of view, carbs are very difficult to beat.

From a bling, and drivability point of view, FI can be better.

For fuel economy, FI is hard to beat.

For total HP output, a well setup FI and Carb. will be virtually identical.

For me, I'd like to do a FI engine not to make more power, but to see how well I could get a Pontiac to run at RPMs other than WOT. I'd like to be able to run solid 12s and get 20 MPG with the A/C on.

THAT is what makes FI appealing to me.
