Why would you want to Y the the two pumps 6" after? I actually like that feature of this pump and not having fish 3 FI hoses and a big "Y" fitting down around the side of the tank and making sure the edge of the tank doesn't rub a hole in the line. Just curious to hear what benefit the external ?"Y" may have?

One of the things I didn't like about my Bushcur was that 3/8 and 3/8 and 3/8 "Y" in fact I ended up buying a different Y, that is actually a real fuel block where I could run the 3/8 parallel into the block or "Y"( the 3/8 fittings are side by side instead an actual "Y") and then they exited into an -8an fitting in a 1/2"NPT hole, in other words big enough to take the two 3/8 hoses. I realize the Bushcurs are good to 700hp with the 3/8 x 3/8 x 3/8 then into a 5/16 hard line "Y" according to most people, but it just didn't seem optimal.


I like the idea of both pumps exiting into one -8an fitting as long as it's done right in the module, and I'm sure it is just by looking at the Squash module. It looks like a quality piece.

 

T is for splitting.
Y is for merging.
Flow rates count or else we would not be doing a double pumper.

 

Just figured I would post a quick update. Everything has been working just fine. The evo is up to about 600whp and the pumps look like they are running very well. Also wanted to post a pic of just how far down I have ran the tank. All the way to empty for me. Here is a pic.

 

Nice, mine has been running great as well.....about 400 miles on it. No complaints here.....

Boz, I see you are running the AEM Infinity. Are you triggering the second pump through the AEM?

 

Yes the Infinity is running the pumps. On pump #1 I run a Low and High Voltage to it, just like factory.

Pump 1 Low == Under 120kpa
Pump 1 High == Over 120kpa
Pump 2 High == Over 180kpa

I am going to adjust the activation KPA for everything once I have some time to sit down and run through the logs.

I also upgraded to -6 supply and return lines which made a huge impact on fuel pressure. Before On my single walbro 255, I could see when the pump would cut over from low voltage to high, and I had very erratic fuel pressure. Now that I am running -6 lines my fuel pressure is very smooth.

Maybe when I have some free time in a few months I will get the boost up into the 40psi range and see how the pumps do on E85. But so far at 600whp they are running amazing.

So at 600whp I am only running 21-22psi. I need to get my boost down to about 15psi or less for road racing.

The cool part about the AEM Infinity is I can set up my boost target map on a full 3d map. Using Ethanol Content on the x axis, and Pot switch for the y axis. So I can have my car run from 15psi to 45psi based on E85 content and pot switch. I will have that all setup during the summer.

 

Glad to see yours is working flawlessly. Mine comes in on Wednesday with twin DW 300's. Can't wait to see how that performs with -8 feed/-6 return.

 

OK, nice setup you have there. Right now I just have both pumps hardwired to be on all the time. Can't wait for spring so I can start cleaning up some things. I was going to attempt to use the OEM high/low circuitry to trigger the pumps but I think I might end up using a hobbs switch instead.

 

Wow, that thing looks amazing..do want.

 

I purchased the unit last December so I have probably been running it the longest with two Walbro 400s. Because it siphon's off the supply side there are not pressure issues running a single pump hotwired instead of through the OEM switched voltage. I have the Haltech switch the second pump relay >3krpm & >12psi. I have never experienced siphon issues and run the car below the empty line and have never experienced fuel pressure issues.

Let Andy know if you have an VIII or IX because apparently there is an 0.25" difference in the depth of the fuel tank with IX being more shallow. I am not sure this was verified, but maybe some with a VIII and IX can take a measurement from the lip of the tank to the bottom. From what I remember the IX was 6.00in and the VIII 6.25in.

I think it was a great purchase and it works so well I forget that I have the setup.

 

Bringing this thread back....I ordered my hanger with twin 450's back in the end of January and STILL have not received my hanger assembly. I have called Andy once a week since and have received the same message over and over again. First they were out of stock, then some parts came in, and now they do not even answer the phone. I swear I feel like they went out of business. Definitely feel like I am being avoided. I have called for the past 2+ weeks with no answer. Is anyone else having this problem?

 

Try email. He was quick to respond when I emailed him.

 

We're not out of business, quite the opposite. We've been swamped pretty bad for the past few months and fell behind. The units will be done soon, with a few nice design changes as well. We haven't taken money for these and will not until they are ready to ship. I apologize for not getting back to you about the unit you have on order.

Andy

 

Andy we have a race in two weeks, when exactly, this is going to happend? Do you have an estimate eta?

 

i spoke to Andy at the end of last week. as of now he said that they are still pretty backed up. sounds like he has a lot on his plate but from the numerous times i spoke to him it seems like he is a man of his word and that the product should been done fairly soon. If your out there Andy, keep up the good work!

 

very nice pump. i paid 600 for mine with a special discount so i lucked out. i must agree. these pumps are bulletproof and just amazing..
