Hey folks. I have a stock bottom end/cam '94 gt that I'm boosting.
My goal is 500rwhp. I'm using a 340lph fuel pump and all stock fuel lines, regulator and rails.
It's been suggested that I upgrade my fuel system including bigger id supply and return lines, billet rails, remote Aeromotive regulator, high flow fuel filter and ProM pump hat.
I've seen videos of guys making 500rwhp with stock Fox fuel system and larger in tank pumps.
I'm curious what others are doing for fuel systems with a 340 pump at 500rwhp.
Thanks.

 

Stock lines and rails are fine for your target power level.
My car is currently making 570whp on stock lines, rails, filter with a 340lph pump.

 

Are those Fox rails and lines?

 

Yes.

 

Do you have a build thread? I don't recall reading it.

 

No build thread. I'm gathering parts to change everything up quite a bit. I'll start a new build thread when I have enough to make something out of this pile of parts.

 

What's a quick run down of the combo?

 

306, TFS heads, Cobra intake, Forgotten cam, Vortech S-trim, 80lb inj., COP, Holley EFI, 340lph pump

New combo is a Dart Iron Eagle block 347, AFR 185 heads, Cam not decided, Holley 160's, Twin 62 (probably)
Want 1500hp from the new combo, so that's the stated goal for now.

 

What is the duty cycle on the 80#? What fuel pressure? Are you logging Fuel pressure? Does it dip any making 570?

Do you still have the 79?

 

1. I'm seeing a max of about 60% DC
2. 43psi base
3. Yes, logging fuel pressure via Holley
4. No, it rises with boost and looks pretty flat.

 

Are you still using the stock FP regulator?

 

No, but only because I don't have one. This is the one that was on the shelf.
#ad

 

Yes, but it's currently for sale.

 

I am really don't need another car, but do you have a link to the ad?

 

I jsut saw that my brother didn't really knock it out of the park on the description. If you are interested, let me know and I can give you all the details. I built it for him and the same day I delivered it to him his wife told him to sell it.

 

It looks really nice. I don't have cash, but buying a turn key car is the best way to do it.

I hope he is enjoying it until sells. He might not want the ad to be written to well

 

He did price it in a nice balance between "He is trying to sell it" and "I don't want to sell it". I hope it doesn't sell. I myself have close to 10K in it. He's owned it since 94-95 I think. Used to be BBF. I blew that up so I replaced it with the SBF Turbo combo.

 

I think if the hood was painted, and holes in dash where filled. Better pictures and ad I would list it for more. But I always price cars high.
