Fuel requirements for 600hp

[Shinker]

I bought an aeromotive 340 pump couple months ago with the intention of staying N/A and keeping my 03 mostly stock but since reading musclemercs recent tvs build I been having impure thoughts. Can that pump support 600 crank hp? Fuel and evap lines have been removed for restoration so I will do Zachs fuel filter mod and the wiring upgrades as well.

[musclemerc]

By itself? No..... twin setup? Yes, if designed correct.

[musclemerc]

Thanks for the mention!

[Shinker]

Ok thanks musclemerc I will look into a twin setup. By the way I was thinking about an M122 Eaton cause they can be had for a lot less than the newer GT500 superchargers. Everything is gonna cost me at least 30% more cause I live in Canada.

I have twins with a return fuel system and over 500 RWHP with no fuel problems. One 340 pump Id have to say no way.

M122 is the route I took. My stock bottom end would only hate life more with a tvs.
I over killed the fuel setup. Twin 340s
Boost a pump, 8an line/filter and bigger injectors. I'm not at 600hp but I would imagine my setup would handle it.

I agree the M122 is a lot of fun. Can't beat it for the cost.

Didn’t realize that would even work or work for very long anyway. Learn something every time I get on this site. I am worried about destroying that beautiful aluminum block. Been planning on buying a balanced rotating assembly so I can put it together in my garage.

The aluminum block is good for 800+ hp... it's the rotating stuff that needs attention and the tuning.

It's in the tune and your right foot. I don't beat my car up, and I know how to drive hard without abuse. Also a lack of traction keeps me from breaking it in 1st 2nd and 3rd.

A single 340 is good for roughly 450 at the wheels, per my experience and the experience of friends also running the aero 340.

I needed a return line. So I bought the earlier panther sending unit with return. I installed a walbro 450 on it. Replaced all the lines with e85 compatible hard line and a fuel lap filter and a boost referenced fpr.

But how about longevity? I hear horror stories even with the texsid block, and fellers going with a newer oem brand new boss block.

I know Jerrys car makes gobs of power, but its not a track car getting 20 passes every weekend.

Just wondering how long the wap block is good for 800 hp, it can be done, but how long does it last is what i wonder.

[Shinker]

Well my situation is e85 not available and 1 gas station in town sells 93 octane. I figured 600hp at the crankshaft max cause from reading what some of you have said 500 at the wheels can be a handful to drive when you get on it. I emailed Hyland Motorsports 2yrs ago right after I bought the car asking what it would cost to get me to 375-400hp N/A and he said $15000. WTF! Body is lifted off frame about a foot so I have lots of room to work and make a a nice system. Any more suggestions ?

[Turbov6Bryan]

Run a dual fuel pump with return system, get it tuned when you install the blower.
Run a dual fuel pump like oem style, without return, and add a boost a pump.

Run a dual fuel pump and run twin FPDM.

Sump the tank and run a aeromotive a1000 with -16 feed..

If your not going to run mega hp, just leave the lines stock.
If your not going to buy a blower, just leave the lines stock.

You will need a built lower end for more than 449 rwhp. Just a suggestion.
And 15K was about spot on, because your paying for labor.
Blower kit 3k-8k motor build 2k-5k + labor.... 15k almost sounds good!
Thats like 50 bucks up thar in canada right?

I like the idea of keeping stock lines and staying returnless. Something that I am unclear on is when the boost a pump is required? I think I like your 3rd option dual pumps and dual FPDMs. Gonna attempt a positive displacement blower install. I bought a lower intake manifold for the 03-04 cobra last night. See if it actually shows up. For the engine I have to send the heads out but figured I could disassemble short block torque heads and mains back down measure w/dial bore gauge and decide from there. I definitely do not need to bore the cylinders. I am hoping I can avoid line boring the mains. I am an old diesel mechanic who doesnÂ’t wanna spend $50000 to get my car built so $25000 and do most labor myself is my goal.

[musclemerc]

Dual pumps, dual FPDM, dual wiring to the pumps, and a wiring upgrade will get you 700hp no problem.

Shoot me a PM and I'll send some notes on my setup. I have a BAP wired but it not turned up

[Turbov6Bryan]

You will still need to replace the rods and Pistons to support higher hp goals

If you're just gonna use that 03 cobra Mustang supercharger, you can just run one fuel pump driver module and one fuel pump and keep the line stock, but if you're going to build a fuel system you're definitely gonna need to build a motor and deafly need to have a bigger blower

but he is building 600..at the crank he says..mine has 600 at the crank with a trilogy..but I don't hotlap it at the track

[Shinker]

My plans are to buy a forged and balanced rotating assembly and install it in my original block hopefully skipping any machine shop work. Nobody around here has a clue about these engines including me but I am learning. I really want to do it myself and if it blows up I will only have myself to blame. I am in no rush to get this done. Probably gonna be a couple years yet. Looking for an 07-12 M122 Eaton. I plan on painting it in my garage as well. Working on the marauder and learning from you guys on this site is the most fun I have had in years.

After spending some time reading about return and returnless fuel systems I think returnless is the easiest and cheapest for my situation. I just need to duplicate the existing factory fuel system and tie them together in the engine bay. Much more to it than that obviously but half the system is there already so would not be starting from scratch. The write up you did using FordnutÂ’s initial design was very detailed and easy to follow. Thanks to all

[musclemerc]

I agree 100%. Returnless is easy and yes your duplicating what's already there from the factory. I saved a boat load of cash having a wrecked MM on hand to strip stock parts off.
Glad to help anyone save some cash. I may post my build here so others can benefit from the design.
I have to give Fordnut credit his original design was well thought out. I made some simple changes to make it my own.
