.....with the fuel system......i already had a good enough pump, but i changed up to #10 lines......DUDE these things are WAY easier to assemble than the #8 hoses, the hose ends go together so much easier.

Heres some of the work on the tank, i bought a brand new tank, and sumped it so it would bolt right up.....

 

heres the sump....which i had to modfiy slightly to conform to the tank

 

another one

 

Heres how well the thing flows out when i tested it for leaks with water....

 

Heres the fuel pump and what not mocked up in the back of the car with the tank in

 

Heres how i modified the stock sender to hook up the return line....the fitting is welded into the the sender, and extends below, and there is a piece of #10 hard line that i bent to match the stock lines that goes down to return fuel to the bottom of the tank.

 

Great work!

 

thanks man.....the blower is in the mail hehe....now i gotta get the engine work done

 

It makes me want to tackle a project like that, but I'm not as confident with my skills, so I'll just sit back and admire your skills.

 

i started at the bottom man, and not that many years ago as alot of people on this board remember im sure.....if you go back and look lol......i wasn't a dummy in the beginning, but i definitely didn't have the know how i have now either.

theres alot of good (and bad lol) help on this board, just gotta know where to look for it, and with the right tools (and enough cash haha) you can build whatever you want.

 

Is that Aeromotive A1000 pump going to be enough for an F-1R? I have a D1 and the A1000 couldn't hang. Other than that Awsome work!!!

 

Congrats on getting the project going.

Are you going to keep the 383 in the same configuration or are you changing the heads or cam or both? Intercooled?

Thanks,

interesting what did you use for a fuel tank setup and what did you use for lines??

cause the stock in tank pump actuallly made it to 11's for me......about 420rwhp. then i had a summmit 140gph pump and that was fine, now i have the a1000

 

oh by the way, its carb'd and that makes a BIG difference.....not sure if you were or not.

that pump is supposed to support like 1300hp carb'd, but its like 700 or something with efi

 

thanks man.......same everything pretty much, only with inverted dome pistons to get the compression down to 8.5:1 and custom blower grind cam (really nasty haha) everything else is just getting freshened up.

 

good work, sounds liek an exciting project! lookin forward to seeing more pix

i'll post stuff as i get it done/get parts in

the blower won't be here for a few weeks, which is ok cause the motor will be out of the car for a while anyways

 

My configuration is EFI. HSR 406 with D-1SC. The Aeromotive pump was used on an engine dyno, where it started to go way lean above 4000 RPM. We then hooked up a Weldon 2025 Pump. Not one Hiccup.

In the Car I also have a Stock tank sumped to Either the current SX inline with a boost a pump or I might replace that with a weldon pump. I also have 1/2" hardline to the fuel rail then an SX regulator back to a 3/8" hardline to the tank. Hopefully that should feed the 780hp the motor makes but I want to see if I can squeeze another 100hp out of her.

 

nice the sump on my factory tank flows just like yours. wayyyy easier than a fuel cell in these cars with less work.

 

Im not sure when this was either, but the a1000 was recently updated....i know they did something to improve it quite a bit.

injection requires alot more pressure, which means flow is restricted....which is why carb's will live longer on the same fuel pump.....weldon pumps are great, preston smith lives right up the street and thats what he uses, in fact hes all over me to get one, but they are way over priced.

you're using awfully small fuel line for your application it seems...#10 hose is a 9/16" inside diameter which is what im using now.....theres no way that pump would keep up with a #8 line that i had before.

 

ya thats what i figured lol....thats why i did it that way.

 

The sump & feed line looks good. When is the larger return line going in??

What were the calcuations you used to determine that a -8 AN was too small and that a -10AN would work? Carbed, yeah -10AN sounds about right.


EDIT - Are those crimp-on butt connectors on the wires??

 

there is a larger return line in there, did you miss that? its #10 as well.

theres no calculation involved, its just common knowledge....if you want to feed 1000hp, you better have good size fuel lines......yes there is a way to calculate that, but it unecessary......this stuff has been done before, so theres no need to re-invent the wheel everytime you do it, unless of course you enjoy wasting time and effort for no good reason.

yes, those are butt connectors....why didnt i solder them? because i don't feel like it

 

I missed the return line. That looks like a good place for it. True, -10AN will work. I was just wondering because I have been looking for a decent fuel line calculator.

 

check out aeromotives site, theres usually alot of good info there

 

The Dyno testing for my motor when we used the A1000 was last August, but I'm sure Vrbancic Brothers Racing had that Pump for quite a few years. I think the Problem with the A1000 is Overall pump volume, The A1000 puts out 45psi of Pump Volume wich I'm sure Diminishes slighty by the time it gets to the rail. When I was dynoing my motor, it required 65psi of fuel pump volume. That is why I think the weldon works so well for Hi-Horse applications.

 

well the you're talking about pressure, not volume......and what makes it possible for the same pump to feed a carb'd motor up to 1300hp, and an injected on only to say 800hp is that fact

pressure (psi) and flow (gph) are inversely related.........as pressure rises, flow decreases and vice versa.....and the more power you need the more flow you need.

with injection, you need say 65psi of comstant pressure, so your max flow is already alot less than a carb'd motor running at 7.5psi

 

I'll agree with that statement.
