I have heard a lot of people say good things about this product. It supports up to 650Hp. I think it may be worth the investment, what do you guys think?

MSD has one two but its really pricey compared to this one.

In my experience with EFI, the holly avenger multiport is the way to go...it doesnt get any better than an injector at the port, unless they come with a direct injection some how....not likely.

seen some good magazine write up on it, but you don't know if advertising money influences that. NASCAR and others racing bodies are using the Holley efi systems, so that says something about the about how good they are.

I have "googled" the FAST EZ EFI and it brought up a bunch of forums with people talking about it and it seems like every loves them so far other than that fact you have to have a return line for the fuel system. I will check out the Holley system pretty soon.

You already have a sufficient fuel system with a return line. The reason I tend to lean more toward MPFI is you dont have the fuel distribution problems inherent in a wet manifold(carb,TBI) system. Better driveability, and tunability.
And with Winston cup racers using the Holly EFI, you cant go wrong. I would gladly bypass any TBI style setup that costs $1500 to pay $3200 for the holly system.

After doing a lot of reading on the subject, I am wanting to get the F.A.S.T. EFI system. The Holley MPFI would be ideal, but I don't want to spend that kind of money. I'm just looking more for reliability and simplicity.

So I guess it comes down to how much money you want to spend

I say go for it, and see how you like it.

I think I'm going to try out the FAST EZ EFI , its seems like its fairly straight forward. I have minimal experience with carbs anyhow, and since my suburban already has and in tank fuel pump and return line it should be gravy. And today i found out i got a job that i start next tuesday i will be able to get back to working on the suburban again soon

Awesome! Let us know how you like it. It'll be good to get an honest review on it.

Congrats! That ez efi should install in a day. you may need the higher pressure fuel pump. you may want to call them and talk a bit.

They have a pump that will go in place of the existing pump. or i can switch tanks with the 86 burb and go with an inline pump. but i like the in tank pumps better, there's a lot less noise and the seem to last longer.

What's your estimated hp# ?

 

[bigtalljohn13]

My estimated HP is around 540 maybe a lil more.

Yeah, then you'll need that Walbro 255 lph pump they have. I was thinking if you were building something smaller then their pump would supply too much fuel for the size of your return line and you would have to install a larger diameter line.
