I was looking at these two pieces for my project. I know these have been brought up before but I am looking for opinions on reliability, quality, experience etc.. I assume I could leave the vacuum port for boost unconnected on the FPR as I am using Hondata to control fuel correct?
Btw, Im shooting for 550whp
Thanks for any input fellas.

the aeromotive 1000hp, 500lph, 10AN in and out, pump is noisy,huge,super reliable and overkill..i believe they just came out with a smaller one,like 750hp 400lph 8AN in and out,for imports,,forgot the name of it that aeromotive is calling it.

and no big mistake not connecting vacuum port,you connect it so fuel pressure raises 1psi for every 1psi of boost

I was under the impression that you dont want to use a boost dependant fuel pressure riser when using the Hondata as Hondata takes care of fuel by adjusting the duration of the injector pending the size value that you enter...?

By boost dependant they mean with a higher rise rate than what is needed to simply compensate for rail pressure drop as seen by the injectors as the injector duty cycle increases.

1:1 is needed to help maintain flow through the injectors. If rail pressure dropped while the duty cycle of an injector increased flow would drop. Of course you could tune your Hondata system to run higher injector duty cycles to compensate for the flow drop but you will edventually reach a point where the injectors can't flow enough fuel to prevent a lean condition. Using even larger injectors wouldn't help much either since you would have to use injectors so large that the system might not be able to cut down their duty cycle enough in order to idle smoothly.

i like my aeromotive pump - i daily drive it with no problems...(its a little loud - but you get used to it) and yes you do have to connect the vaccum to the FPR even with the hondata...

i had a paxton external pump before... it was loud but i looked at as i always knew when i was getting fuel

Check my sig, got one for sale

It's funny that you ask. I am in the process of doing a complete write up on the install including install pictures, parts list and a drawing I did in AutoCAD. This is what will be included in the write up:
Aeromotive 1000hp Fuel Pump
Aeromotive FPR
Aeromotive filters (100 micron)
8an feed and 6an return lines (including part #s for all fittings)
JAZ Fuel cell mounted in trunk.
I should be completely finished by the end of next week and will post it up. If you want to buy any Aeromotive parts, I suggest that you buy the parts from "Muscle Motorsports". They seem to have the best prices. I got the pump for $250. Good luck.

Actually that fuel pump runs out of fuel around 650 whp. I have seen it personally. As far as leaving the vacuum port disconnected, that is an AWFUL idea. The fuel will not be delivered at an accurate rate if you do this. You need a 1:1 rising rate to kep the fuel spraying properly.

how are you going to feed the pump? I like the idea of using an adaptor from the gas tank drain to a -8 line then use that to run to a filter, then to the pump. It works well

I used it on my old race car b18c and now I use it on my street driver, its works just fine. One thing I love is when I start up, it roars like a lion, much better than the old bosche I had.

I currently use that pump, fuel filter, and fpr on my street driven civic. I can certainly attest to it being loud, especially when running less than a 1/4 tank. However, I can safely say I won't be running out of fuel due to the fuel pump anytime soon !

damn geoff cutting it low there no? you must drive very carefully on some roads

Dublocivic

Ahh ok, I was a little confused about how Hondata and that FPR would work.. silly me.. I didn't notice it was 1:1.. Thanks that makes sense now
BQQsted Hyb:
Thats great you guys make this way to easy to go fast!
I suppose 8an would support 550-600hp. I am actually going to retain the factory gas tank.
FFgeoff: I was going to modify the stock feed with either 8 or 10an replacing the factory pump location and just get a new factory sock using some hose clamps to secure it all to the factory brackets.
Are you all using an inline filter before the pump? I figured I would just run one attached to the firewall similar to stock.
I noticed that Aeromotive suggests that you run one before and after. I suppose that would be the way to do it if the factory sock setup was a restriction.
Thanks for the reply's.
Let me know if Im way off base here with modifying the factory pickup.
Thanks for the help!

Your going to need more fuel than that for what you have planned fool!

so if im getting a hondata then i will also ne a 1to1 disk setup for my vortec boost dependant fpr? thanks

lucas569

ditch the vortech bd fpr, all youll need is the aeromtive plus some big *** injectors along w/ the hondata. youll need an aftermarket rail w/ ss lines or youll need to tap your stock rail. if your going w/ low fp you might want to consider the aem fpr,bolts right on to your stock rail.

You guys don't understand what the 1to1 rising rate fuel pressure regulator is for. you very much need this feature hooked up in a forced induction application. The way it works is say you set your fuel pressure at 45 psi then when you boost say up to 10 lbs, and your injector opens, the 45 psi of fuel pressure is going to run into the 10lbs of boost pressure and effectivly cut your fuel pressure down to 35 psi of flow. That is what your 1to1 fuel pressure regulator is for, for every pound of boost it sees the fuel pressure will go up one pound so that you get the same amount of flow through the injector. so at 10lbs of boost your fuel pressure will be 55psi but the injector will only flow the amount of fuel that a nonboosted injector would flow at 45psi.
