Basic kit is $650, or $250 less than the MDR kit. I don't know if they will sell just the tank if that is what you are asking. Maybe Kevin or Josh will chime in, if not I am going by the shop tonight and can give you an update.

Either way, very nice piece. It was soon to come, another surge tank production kit made in the USA, bolt on for the USA .

I think they have only built one for the Evo x so far. I am not sure if the ct9a needs it. We have quite a few locals running stock tank without issues, but the EvoD race car has one so I am not 100% sure

Any one that is going to be running 420+hp on E85 will want to make sure they are running an upgraded in tank (oem) pump as well, or the surge tank won't stay full. If you're running less than that, or on gasoline, the OEM in tank seems to keep up pretty well.

actually, the stock intank pump can supply fuel to VERY large setups utlizing a surge tank without an issue. because the intank pump runs at 0psi pressure, it actually flows more fuel then a walbro 255 at 50psi (10psi boost). the more boost you run, the easier it is to keep up.
in my race car i have a surge tank, but i also have a fuel cell, so its a little different setup then a standard evo 8/9. i have a single walbro 255 feeding a weldon DB2015 1000hp fuel pump. never had a problem.
we are already making the bracket for the evo 8/9, but for evo 8/9 its not nearly as much of a problem as the X's as jim pointed out. the only time my car ran dry was at below 1/4 tank on hard left turns.

My stock in tank had no problem keeping up with a walbro 255 on E85. I started having fueling issues at 474 hp on a mustang. When I switched to a Bosch 44, the OEM in tank started having issues keeping up, however it kept up during dyno pulls without issue, at least to 500hp. During full 1/4 mile runs however it would start starving for fuel around the 1000 ft mark.
I am fairly sure that a 255 in tank set up like you have in your race car will have no problem keeping up with a Bosch 44, at least around the 500hp mark. Again this is on E85. On gasoline, the stock in tank pump has no problem keeping up all day, and a single walbro 255 is good for over 500hp as well with this system.
I am putting a fuel lab 41402 in over the holidays for testing. This pump has variable output with a controller built in. It should help with some of the issues regarding return system pressure build up under low fuel demand that X's can have when running high volume pumps (larger than a 255). While it isn't cheap, it isn't stupid expensive either. Keep your fingers crossed that it actually works the way we're hoping.

Yeah, the X has the issue way worse than the 8/9's.

my car was quite a bit different, it was a fuel cell with a 255 external pump feeding the surge tank to a weldon pump (like double the size of a 044). it made 590whp on e85 and had no issues on much longer straights then 1/4 mile.
