Radium surge thank with a walbro 400 e85

 

This is what I'm going with I think, anyone else running big power on that set up yet?

 

I was thinkin this with a bigger lines

Anything in tank will starve in a corner under 1/2 tank
double pumpers suck.

 

Never tried to fix the starvation issue on my evo yet, but is the OEM cell serviceable? If so, see about a set of these: http://www.autoperformanceengineering.com/html/pickups.html

They're basically like reverse check valves. When they're not submerged, they close. Put one in each corner of the tank, and you'll never have starvation issues due to sloshing. We run them in our ATL cells on our race cars and they make a huge difference. Way better than the mousetrap and surge tanks we've tried.

That said, if i were going for a 700hp setup, there is no way I'd trust the factory fuel setup at all. I'd drop the factory tank, cut out the trunk floor, and recess and angled 26gal ATL 600 series cell in there. Partially cause I know that setup pretty well, and partially because the fuel tank's too small already... at 700hp and if running e85, UGH!

 

I don't have and fuel starvation issues. auto x was no problem

 

For strictly drag racing I don't see an issue with just a double or single up to the 600's. Over that A surge system ain't a bad idea. Track or autox is a totally different animal that makes the flaws in the stock fuel system more apparent as already stated. It just depends on how serious the person is with their build if they want to drop the coin on a surge setup.

I personally don't go WOT in my car under 1/2 a tank on E85 and haven't bumped into the Fuel gremlins yet but I know they are there waiting.

 

I can almost guarantee you they are there!

I guess after all the bs I have dealt with I would still prefer a surge tank in any situation as I posted earlier. Yes you can get away with a problematic setup by running higher fuel levels but it sucks to deal with. I want something rock solid and the surge tank is the best way.

Plus, for drag racing you want light weight or any racing for that matter, so getting rid of half of a tank of fuel helps a lot.

 

The only Issue that I have with the radium surge tank is that it doesnt hold a very large volume of fuel

 

To fully drain their tank you still need to run WOT for quite some time, I don't think anything but a road racer could do that. The drag racer and street car will never run it dry with a 255 in the stock location feeding it.

 

This cost efficient compact design can support ~1025bhp (or 825bhp on E85) @ 3Bar Pressure/.67 BSFC. This number will be approximately 20% lower for forced induction.

This worries me a bit, I would hate to get this set up and then find out I really needed these guys.

 

I ran my wally 450 up to 760whp with FIC2150's... on e85. Those pumps support a lot. If you need more above that, you throw a boost a pump on there, problem solved for 99% of applications.

If you intend to be that 1%, get a bigger surge tank, custom one, put the wally 450 in tank, then use a weldon pump.

 

weldon setup ftw!

 

I had wiring issues with my double pumper. rewired it and seems to be consistent but if I run into issues again I am going to try something different.. the set up we run in out mustangs and ls1 powered cars are pretty simple. just pull tank. add rear sump and run a areomotive pump. inline filter and a 1way valve. we have had over 1krwhp set ups with plenty of fuel change feed and return lines. 8an feed 6an return, we will see.

I like the serge tank option but the way I see it that people have had simple set ups and no issues.. I don't like trying to fit 5lbs of crap in a 3lb box.. simplicity is the key.
