Evo X upgrades

sounds like he probably has the MDR setup I would guess.

I'm not sure how a $250 piece of electronics is simpler than just getting a higher capacity pump. The Fuel Lab unit that I linked to is 450lph at the standard voltage (13.x). The cost works out about the same.

I read through the MDR thread and I see that Goofy does have that setup. Sounds like a workable plan B.

It is so you wouldn't have to buy another fuel pump basically.

But since your setup is pretty different right now, it probably works out to be the same.

Boost a pump on a 255 or rig up a way to run the ford gt with a boost a pump and call it a day.

How much power do you plan on making again? Seems like you're going over the top if you don't plan on making a million hp.

Lomkers fuel path wasn't a bad way to do it in the beginning. With the limited offerings for injectors direct drop in fuel pump upgrades etc for the X when he first started this it was logical to do it this way for limited down time.

It's easy to say now that he shouldn't done something else, but at the time it seemed like a good idea.

But the main problem is an inherit problem with the X fuel tank and fuel starvation when cornering.

You guys must be German because you are overthinking and over-engineering everything. :)

Dunno what it'll make. 475 maybe? A single 255 maxes at 420@DB on a X. I see that a Bosch 044 inline is rated for 300lph. Might be enough and it might be a limitation.

Maybe somewhat but I think what Shane said to me yesterday sums it up when I asked him when he was going to buy an Evo and he said he would consider a 9 RS because "Everything is more complicated on the X's".

I think a lot of people on this board are oversimplifying the situation and just assume its just another DSM and all the old tricks work perfect on the X's and all that good stuff and that there isn't any reason to do certain things etc etc.

Like I said, it's easy to look back now and say should've gone a different way, but it's not like the plan wasn't thought out...the X's design is what made problems.

Satisficing landed me with three sets of injectors ($1900) in just six months:

800cc was fine for pump.
1000cc was fine for E85 on stock turbo.
ID2000's are overkill but there were no intermediate sizes at the time.

Same goes for the fuel system. A single pump wasn't enough. An inline Walbro will work up to my current power level but not enough to max out the car. Where do you go from there? I went to an in-tank double pump and I'm now on the second setup (which generally works) but struggling with a fuel pickup issue due to the X's tank design.

All I want is to max out my car and have enough growth capacity to allow for bolting on an FP Black next year. It's looking like a surge tank setup with a Bosch inline would satisfice but I'm not sure if it'll be enough for the Black or not.

That's why I'm looking at the Fuel Labs that is around 450lph. I found a couple racers running it but I need to figure out where they mounted it since it's a lot larger than an external Walbro.

I'm just curious is all, I didn't mean to say or infer you're doing anything wrong.

I know most DSM's max out a single re-wired 255hp @ 450 at DB and thats what mine maxed at. I threw on a boost a pump on my single 255hp and last October I made 520awhp @ DB and it didn't seem maxed yet. I'm just thinking if you're not going for huge power and the stock sending unit isn't complete garbage it might be simple and less of a headache in the end to try a boost a pump.

It also wouldn't be hard to make your own surge tank, just finding a generic one and mounting it would probably be the hardest.

Good luck though, thing should be fun when you're all said and done. If that ever happens haha. Car projects never seem to end.

The X is fine if you stop at a single Walbro and basic bolt-ons. Getting much over 400@DB seems to bring on the hurt.
