BOE surge tank - Top product & excellent value.

The company I am associated with has fitted 7 of the BOE Surge tank kits to customer cars over the past 6 months and the feedback has been very positive. Not only does the kit do what BOE says, it has an ingenious mount to keep it out of the way of other components and maintains short line runs.

A great product.

Just completed the install of one of BOE's surge tanks. The components are top notch and the install was fairly easy. It took me about 3.5 hours total, but I also took the opportunity to remove the washer fluid tank bracket (the tank was already out) and move my catch cans where the bracket was. Everything looks really clean and I can finally get my hands down to emply the catch cans.

I had some trouble (user error) with getting the quick connects seated on the hard line from the tank and the fuel rail, but was actually able to call Phil and have him walk me through it. These guys at BOE really are great to work with.

Just installed mine last night. Like 5qf3764b had mentioned, the pieces are definitely top notch. The only things I think that need to be noted is that make sure you check the markings on the lines. The instructions show blue lines being the high psi lines that go in and out the fuel pressure regulator to the fuel rail. All the lines in my kit were black, and I did not really pay much attention and attached the wrong one to the fuel regulator (this is probably more my fault than BOE's). But it'd be nice to throw a piece of blue tape or something on these lines since the instructions are not updated with black lines Another item is I wish they went into a little more depth of how to use the quick release and what size disconnect tool to get (I used 3/8").

Other than that, a beautifully constructed product

A few words of advice on the install: In regards to disconnecting the quick-connect line, make sure you get the SAME tool as the one shown in their instructions (white piece). I tried a metal Ford "all-size-in-one" tool and it did not work, nor did a similar brand with weaker/thin contruction. Fitment is tight but with a little play it'll pop right out.

For anyone interested, I finally got around to updating the installation instructions...

MORE POWER from Your Lotus

It recently occured to me that there's an information gap of sorts about making a lot more power and fuel supply system on the car.

90% of our surge tanks are used to help curb fuel supply issues on the track or Autocross. Makes sense.

The other 10% are used just to do away with the restrictions of the stock sending unit when trying to make more than about 320whp (dynojet).

To put it simply, the hole coming out of the tank cannot keep up with the fuel demands of 320+whp or so on pump gas (let alone E85)...(it's not just the hole coming out, but the passages inside too)

If your power goals are 320whp or betteron , then you will NOT be able to reliably get enough gas through the stock bulkhead on the fuel tank. Now, there are some slight exceptions--- sorta. On a street car, you can run a leaner mix and we've made 340ish whp on pump gas through the stock pickup before--- it was sketchy though! We tested that same car on a cold day (when fueling demands are higher) and it went LEAN-- BIG TIME. Even in that case we had to modify the pickup/bulkhead to the max to pull this off (drilling out the passage ways and lathe out an aluminum fitting where the bulkhead meets the filter housing). Like I said, it still wasn't correct since the car can't be ran on cold days at WOT... Solution: 1) Surge Tank or 2) custom fuel pickup and buklhead.

This is all *obviously* assuming you're running a 255lph pump in the stock filter cartridge as well... A stock pump is far inadequate for this...

If you're running E85, that number will be reduced since the fuel to air ratio with E85 is quite a lot more, so the fueling demands are quite a bit greater.

So that is the other 10% of surge tank orders. They were street cars with forced induction who are power hungry. Even with 400+whp on my personal time attack car, we get zero pressure degradation at WOT. We have a few customers making over 400whp on E85 with our surge tank as well...

Cheers,

Phil

I have a 2010 Exige 260 and i installed a BOE surge tank a few months ago. i am having a fuel issue that i wanted to see if anyone else has any input on. i am getting plenty of fuel to the engine but my fuel gauge drops very fast. so a couple of months ago i drove it until it was empty according to the gauge. i filled it up and it only took 6 gallons. so it still had about half a tank of gas even though the gauge was reading empty. so a few weeks ago i went to an out of town autox and filled up before i left. drove about 75 miles to the event, ran the event (10 runs of about 43 seconds). when i left the event the tank had one bar left, by the time i had gone 10 miles it had 0 bars left. i drove another 50 miles with NO bars showing on the gauge and filled up. i only got 8 gals in so there was still 3 to 4 gals still in the tank. since the fuel sure tank is the only fuel upgrade i have done i am guessing it is the culprit.

do you know how the stock gauge works? does it measure how much fuel is pumped or is there a floater in the fuel tank? it seems as though take goes down based on what is pumped to the surge tank, and does not take into account the fuel being pushed back into the tank. this is just my observation i dont know enough about the fuel system to know.

lastly, it is not that big of a deal since it is reading lower than what is actually in the tank. if it was the other way around i would have been more proactive about finding an answer. any input would be appreciated. thanks.

I also have a question for BOE or anyone else that can answer.

I am brand new to Lotuses and am going to probably be buying an '08 Elise SC tomorrow. I don't plan to track it *yet* .....but may end up doing so later.

How common is the fuel starvation problem for basically stock SC Elises just used to drive canyon/mountain roads? I have found a really cherry Elise SC to buy and the last thing I want to do is blow the engine.

Should this be something I upgrade immediately, or can it wait until I mod it more or track it?

Thanks,
Sean

You will be fine Sean. This is for track cars. Just don't drive aggressively in the canyons low on fuel.

Sounds like there is something wrong with the float in your fuel tank. Take it to a dealer if you can to get it looked at under warranty because it's a bit of a pain to get to.

our closest dealer is more than 4 hrs away, that is why i was asking on here. i wanted to see if there was some reason the Surge tank would cause this or was it just a coincidence that this started with that install.

...catching up on the forums...

Just confirming that, yes, there is a float in the tank. Sometimes they can be problematic. Can also be dash related.Fuel level comes in through CANBUS, FWIW...

On the newer cars (06+) the sender unit is comparably easier to remove than 05s. If you have a weekend with nothing to do, you could pull the sender and investigate.

Best,

Phil

Just want to give a shout out about this product. I know many have said this already on this string about this product, but I lost my engine on the track as well and suspect it going lean. I installed the BOE surge tank as cheap insurance. Yes cheap compared to the rebuild. Amazingly I have yet to find anything negative on the forums about Phil or BOE and I must agree they are great to work with. (Phil do you sleep?) Especially since I picked a less than steller local shop in Atlanta, Phil had a lot of extra communication/work to make up for, and he did. Thanks a bunch!!!!!

I run the BOE surge tank and yes Phil's backup is excellent. I did have a problem just after I installed it in that it stopped puming on two separate occasions. It came down to a failed crimp on the positive cable and then the same thing on the earth side.These were hard to find as they were under heatshrink. I contacted Phil after I rewired and soldered the joints and he said that this was the first case he had heard of. It has run flawlessly for over a year now.
