Nothing beats a 4K rpm power band. Why did you run pump gas through it?

If you scroll back a few pages there's some gunk building up on my intake valves, the intake ports, and the IM runners immediately opposite the injectors. I'm guessing I'm getting some form of the black e85 gunk build-up that some complain about. Car seemed a little down on power in December, so I ran a few tanks of gas through it based on the recommendation of Shane@DB, Aaron@ER, and a few others I trust (and it helped). Switched back to e70 for a while, and now I plan on putting a tank of BP93 through it every 4-6 weeks to help keep things squeeky clean.

Did you ever check to see if the first tank of pump gas cleaned them up at all? aka pull the intake mani again and look?

Just curious if the tank of pump for sure helps. If so might be good for quite a few of us to do.

I ran a tank of pump through mine every month or two in my Evo also. When the buyer pulled the injectors he said he found no black gunk anywhere.

Regular gas cleans up the junk right away. I had so much junk on an injector once that it basically clogged up. Ran a couple gallons of pump gas through the car and everything was looking brand new, didn't even take a full tank.

Wondering if you ever checked this?

Also, when you hitting up DB again for Shane love?

Gonna check when I swap on some new bits here next week :D Need to make sure I have my ducks in a row before it hits the rollers. Work schedule is insane lately but the car is running great! I'll hit it when the time is right :)

Work has been killing me but I've plinked away at a few things on the car in my insanely limited free-time.

First off the car got insanely lazy...CEL told the whole story and after a few weeks of laggy laggy EF4 I got my hands on a used rear CAS...mivec does not work so hot without it I guess because it improved spool 500-800rpm (depending on the run)...the car is SO much more fun now, EF4 drives like my BBX:

Also noticed a clunk from the rear when leaving parking lots after I swapped on my summer tires a few weeks ago...turns out one of the rear sway-bar mounts loosened up a bit. Whiteline bar is looking healthy and the bushing was still there and fine, so 1/2 turn of each of the mount bolts did wonders!

I've been planning and planning and planning next-steps on the fuel system to keep up with the EF4 and I have good news: as of now I won't be doing hardly any of it! I picked up a Boomba fuel rail from MAP on Friday:

The thing looks nice and slick! I swapped it in in about 30 minutes and jimmy-rigged the stock fuel return line to work....but the thing leaked like a siv from the FPR :( After a weekend of drinking and running around finding o-rings and sealants and basically dinking around with this thing I realized that I am a dumb-ass and didn't read the directions....

I thought I was being all clever installing the FPR the way I did so I could have a nice clean return-line setup...I bought 4' of new fuel line and some new vacuum hose to make all of the lines perfect--uncluttered, not a ton of fittings and clamps to eventually leak on me:

And best of all, finished product (LOL):

So yea like I said, I was thinking I was all clever with the way I mounted the FPR 180° from how I'd seen Lomker mount his but it turns out there is a reason...there is no problem with the o-rings or sealant or anything, there is a problem with the clearance of the stock FPR bolted on the way I did it:

Notice the lip of the FPR hitting the body of the rail...GAH! it was tweaked and causing it to leak like crazy no matter what I tried with the o-ring. DOH. So I bent it up a bit and made sure it was all clamped nice, used the o-ring supplied and voila, no leaks and the nice new rail works great!

One thing I noticed when I was troubleshooting was that the housing of the FPR itself was sorta bent from the prying...I THINK I basically made my FPR a one-time adjustable FPR by slightly elongating the body because with the new rail and everything buttoned up my fuel pressure with the car idling and vacuum hooked up is 40-41...it was ~50 before on the walbro 400 pump....what does this mean? It means hell yes! My next step was going to be a full AFPR kit to try and lower fuel pressure and try to get a bit more flow out of this thing at high boost levels...

Well, here are the results...the car has more fuel everywhere but seems to be down a tish on power...I think the next step is dyno time as timing is still a bit all over the place but my main goal with the w400, dinking with the siphon, and this rail was more fuel and I got it!

*virtual dyno* don't read into this too much ;)

The car should have enough fuel system now as we go from E70 to E85 here soon...hurray!

[Murlo26]

Looking good man! Glad the fuel rail helped out, maybe it is a restriction when you move up in power.

Luck ran out on the cheap/free UICP that came with the car (made by the place in SD)...got a leak on one of the welds :(

Boo. I just did da gheto-fix for now, I'll have to get it welded up after the cruise, only shitty thing is I gotta get it re-powdercoated too. Dayum.

But on the up side, look what I found in the alley! It has a flat tire, big woop!

some pins to lock the handle, a new tire, and some casters and it'll be bitchin

[goodhart]

Those tires pop off all the time. Just start fillin it with air and wiggle it around. It'll pop back on the bead.
