speak to matt @ fps. i just bought a similar fore system for my build with 2 x 50-120 pumps n a set of bosch 1330cc injectors. cheaper than what is listed on the fore website aswell.

Yep sure it is, take three pumps setup, everyone knows the only medicine to this sickness, it's more power and easier if you upgrade the fuel system immediately handle future needs.

Call to Justin, he helps you with fuel system and tell what do you really need.

Do the AEM pumps. I'm running the dual 320s.

ECS kit comes with mounts for z51 or z06 oil cooler. I forget if you are a z06 but if so just put the stock oil cooler there. I'm currently running no cooler but have a z06 one with mounts laying around. Right now oil temps are fine but I don't road course/etc and I doubt you will either with 800+rwhp.

Setrabs are nice but if you have the factory z06/z51 cooler it is just cheap/easy to use that.

That is fine...

Friend is running a similiar setup, RSI fuel hanger though... (they no longer make them)

Dual in tanks, Bosch 1000cc injectors, Alky Control Meth.

Injectors are at 85% duty cycle on a YSI powered 408 @ 21 psi @ 6800 rpm.

Plus 1 for the AEM's. But nothing bad to say of the Walbros either.

Get bigger injectors if you plan to run E85

I use the Z06 oil cooler and it works just fine

Tuomas FIN

Surprise they discontinued, that was the real art of bulls*it.

I have a Z06. ECS doesnt like using pumps inside the tank cuz if one fails/melts there is no fail/safe ...they like using their own kit which uses aeromotive pump with hob switch

I have also read good things about Fore...

Damn decisions lol

Unreal

Yep, that is the risk you take with dual pumps in tank. Big single is the only way to avoid that, but that is a whole different set of issues. Good luck. Fuel pump stuff sucks.

breecher_7

That thing has been the most problem free fuel system ive ever dealt with. Once we resolved a simple fuel transfer (tank to tank) issue, it was smooth sailing. We just let both pumps hum all the time with zero issues. Been like that for 5 years now. Probably has 20K miles on the fuel system.

Tuomas FIN

Fore uses hob switch as well. One on vacuum and adds two under pressure.

External pump is easier add to factory fuel system with hob, another pain in the *** job take the tanks off..

Unreal

Fore can be done anyway you want. I'm running both pumps full time. Then again I made my own relays/wiring. Using a hobb switch is one way to do it but I just did both on all the time.

breecher_7

Best way to do it... No switch to fail.... I dunno why people are so against this, it has worked great for me for a long long time.

Mookster

Many places i talked are against having fuel pumps on at all times and they had a slew of reasons(i dont have my notes in front of me to refresh my mind what those reasons were)

Mookster

What issues are those? I've heard they are loud as hell when on?

Just talked to a local shop and they like Magna 750 fuel pump that they setup basically to come up when ur "in boost" or when you need it

breecher_7

The reasons are b.s.

Heats up fuel.. Blah blah blah..

I've been doing this on different 1000+hp cars for years without issue. Street cars, driven 1800 mile round trip type street cars. There is zero negative effects to running two pumps all the time that I have yet to find.

Mookster

^Yup, heats up fuel was the biggest issue but i think they were few more. Didnt someone say u can have a hob switch with Fore, wouldnt that be better?

turbotuner20v

That's what I run, external 750

Unreal

How is that any different or better than 2 pumps in the tank? If the external fails then the stock one will still be pumping and you go lean. If you have dual pumps and one fails, you go lean. I guess the only advantage is if stock pump fails as the big pump is going and big pump is enough on its own then you are ok, then when it shuts off car dies. Either way you have two pumps unless you do a big single in tank.

You can wire the fore any way you want. Hobbs, RPM switch, big red button on steering wheel, etc.

AEM pumps run pretty cool so I don't see running 2 all the time as a big issue. If you had something like the aero 320s that are little heaters that is more of an issue.

Big singles are picking, need controllers, are loud, typically have lower service life, etc.
