Evo X upgrades - Page 92

Glad you got what you needed!

Now that I've inspected the stock hanger more closely, it's a rather elegant design. A part of the return fuel is used to create flow through a check valve at the lowest possible point. I'll genuinely be surprised if it doesn't solve my issue.

Scheides texted me saying that he was seeing identical symptoms...a 300lph pump isn't even enough for a BBX on E85...it leans out above 7k. That's why I ended up installing the BAP. It borders on nonsense how much pump the X needs for E85.

At this point I'm planning to get the stock hanger w/Jay Racing 340lph pump into the car. I'll test that on the road course at Proving Grounds next month. If Scheides ends up with the same results that I had (needing the BAP) then I'll proceed with installing the Weldon in July.

That was the very first thing I noticed when I looked Scheides' hanger over.

Those Mitsu engineers got something right; it's cool how things like the return can be designed to serve an important purpose. Hope this is the end of your fuel issues.

I've been reading around about oil leaks and it seems like the most common place to leak is from the timing cover and a lot people mistakenly think it is coming from the turbo oil feed. Mine leaks more than a few drops so it probably is the oil feed.

My timing cover leaked. I got it covered under warranty

Even after cam install and E85 Fpred etc etc.

WARRANTY! DO IT!

**mlomker** · 05-22-2011

Decided to order a 1/4" tq wrench to snug up that oil line bolt. If that doesn't fix it then playing 'find the oil leak' will be my next adventure.

I got the stock fuel hanger half installed this evening (spent most of the afternoon hanging out with simulatedwood & Toothy while they did brake jobs). It is clear that the FB hanger does not sit on the bottom of the tank--I've always wondered about that and assume that the stock hanger is spring loaded for a reason.

**Murlo26** · 05-22-2011

IF I remember right, the blaqops double pumper gets rid of the springs. It just uses good ole gravity and the weight of two pumps to get it to stay low.

Gravity would be inadequate when the car is bouncing around. I doubt that they removed the spring since there'd be no good reason to.

In any case, I haz stock hanger.

FWIW if the initial torque doesn't fix it, replacing the crushwasher should still be the next step. When I installed an IX turbo on my VIII I accidentally got a teeeeny grain of sand on the fitting and after about a month or two I noticed a fine mist developing on components immediately around the feed banjo bolt. I took it off, could clearly see the grain of sand wedged into the copper, gah! Fresh washer and very careful to make sure all was clean and it was very clean from there on.

Woohoo!

Why is the pump hanger thing able to move at all? shouldn't it be stationary in the tank at all times? Seems illogical to be moving around. One more part to cause problems.

Definitely. On Wed I'll tighten it and spend a few minutes cleaning.

Not sure what Mitsu's reasoning was there. The X tank and hanger design is different than previous Evos.

so... did it fix it?

Won't know until Proving Grounds, which is my next track day. There's no way to drive the car that hard on the street.

What about somewhere like 494/394 intersection where there's cloverleafs on all 4 corners? Go there late some night and keeeeep going right! Or wait, is the problem supposedly on hard left corners?

I guess I'm spoiled with nice roads where I live.

The working theory is that the surge tank holds ~45 seconds of fuel and after 6+ minutes of the tank sloshing in all directions, the surge tank was able to be emptied. The car has been solid on the street for a while now.

WOT for 6min while braking and turning would be pretty darn tough anywhere else.

Have you ever done road course? Sign up, man. The more Evos the merrier.

If some of you guys aren't busy then you should come over to the short course and at least hitch a ride. It's some addictive shit and it's nothing like the street, imo.

311evo · 05-23-2011

I just hope you don't pay the money and time for a track day, and find out the issue is still there. Story of your car, right? :P

Good luck!

**mlomker** · 05-23-2011

My solution for all of the silly bolts on the SSP undertray.

I've always wanted to, but I can't afford it at all. The amount of work I would have to take off, and to get everything totally "safe" for the track would already me too much. Then there's the price of actually going to an event too. lol
