hey guys, i'm looking to do a large turbo setup next year, t76 or so.

i'm redoing the fuel system right now and was contemplating how to do it.

i'm buying an areomotive a1000 shortly that flows 500gph.

should i sump the tank and run a new line? or take my stock line and put the aeromotive inline to boost it. i'm worried the stock lines between the intank and inline pump will restrict flow too much.


what size of line should i run 1/2 or 5/8? can't remember what size the aeromotives use..

anyway, i'm looking for 700 hp out of it.

 

Wow, looks like we just about asked the same question. The mods may want to merge our threads?. i think we have moderators here?

 

If I remember correctly Rich ran the weldbro intake pump with stock lines on 700hp. If your redoing the lines go 5/8 front 1/2 back, and buy a weldon not aeromotive.

 

WHY weldon?
my buddy worked for roush and they did alot of testing on the aeromotive pumps, they seem to last forever. do the weldons flow more?

 

There seems to be a reliability issue with Aeromotive pumps. I havent heard anything lately about them but Weldon is a badass pump though.

 

I am a fan of running dual walbro inlines. Quiet, and can flow what you need

 

I run the A1000 on mine, and a friend has one on his 93. Mine is a couple years old, his is about a year. No issues, and they are pretty quiet. I would run a 1/2 or -10 on the suction side, and at least 1/2 or -8 to the motor, and a -6 or 3/8 return. I run the 1/2 feed-3/8 return on mine, and it works well. I can look in the top of my cell and the return is a solid jet coming back, so it doesn't appear to have much restriction.

 

i think you may be confusing their regulators and pumps, i hear the regulators are unreliable, but nothing bad about the pumps.

 

Actually I had issues with the Aeromotive pump. My pump had less than 100 miles on it and it quit working. If you do not run a voltage regulator with the big pumps you will encounter alot of heating issues in stop and go traffic.

 

Don't have any experience w/ A-motive's pumps, so I won't go on what I heard.

I run a 2035 Weldon in the turbo car w/ the Dial-A-Flow and adjustable regulator. I sumped the stock tank, but modified the sump because of the sissy-*** 3/8" ports.

 

A1000 is a great pump....now. Earlier models like 4-5 years ago had problems but the pump issues have since been fixed. Do yourself a favor and run some sort of sump. Twin in-tanks would do, but the ease of an external pump is a really nice. Also run as big of a feed line you can (1/2" min.) if you really want/think you can get 700HP. My car makes 500+ to the wheels and I'm using a 5/8 hard line and -10 hose to feel the A1000 then use the stock feed line, rails, and return lines from the pump. I have had no issues, and fuel pressure is rock solid all of the time.

 

i agree, no need to go crazy like that for a first set up.. i am using two INTANK WALBROS and have more left.

a single in tank can get you 700hp... dont go choppin up the car allready.

 

why not, do it right the first time so you don't have to redo it later...

 

The guys saying that he needs a 5/8" line have me confused. I crew a race car with a -8 fuel line that feeds 650hp at 8psi, so I can only imagine what kind of power you would make to need a 5/8" line. I don't know where, but I read an article that explained why bigger isn't always better when it comes to fuel systems. The dual intanks sound like the best deal, since they last forever and provide plenty of fuel.

 

NOSFED, here is why I used 5/8" line. In the Aeromotive F-Body kit they send you a roll of -10 braided line plus the inlet and outlet of the A1000 have -10 fittings. I figured if I was going to buy some tubing anyway why should I restrict the pump inlet by using smaller tubing? Additionally, an A1000 like's to push the fuel, better than pull fuel. If you restrict the inlet you make the pump work harder. I read once it's just like drinking through a straw, you get more when using two straws with less effort than using one straw.

IMO on bigger isn't always better, I agree sometimes that statement is not always true. However on a boosted EFI application give me more everyday of the week. All it takes is one time running lean and your engine is FUBAR.

When you say you make 650HP using -8, you also said at 8psi. I'm guessing we are talking a carb application? If that is true I would say -8 is fine, the carb is not a return system like an EFI set-up. As long as there is sufficient volume to the carb you don't have a problem. Since an EFI is constantly returning fuel to the tank the fuel is in constant motion. So I think the pump must have to work harder to do this. Experts out there correct me if I am wrong....

Lastly, I was going to do the dual intanks at one point, but I talked to MORE Performance and they said since I already had the Aeromotive pump, why would I want to take a step back to an intank set-up. They didn't bash Racetronix or anything, but they did say the Aeromotive is the way to go. Plus I have never heard of a fuel pump that lasts forever......
