But you guys are internet racers, you have to at least have a chance on paper to be happy.

Re: Dave's Evo X Build/The Life of Dave blog
 

I drive my car more than you do :)

So boom.

Re: Dave's Evo X Build/The Life of Dave blog
 

Silly VD numbers...but 500whp on 93 at 24psi...yea...sweet...

Haha. Hope it makes it to pg this year.

Re: Dave's Evo X Build/The Life of Dave blog
 

So, battling fuel pressure problems right now. My AEM is adjusted for max fuel pressure and it won't go above 42ish at idle.

So as I believe Shane suspected, the car appears to be bleeding fuel back through the second pump. Doing some testing now, but might be getting a check valve for the second pump soon.

Need to bump fuel pressure so we can reduce load as I was hitting 330load and boost cut (319 load) on pump gas at like 24psi.

So we are making it so the load is hopefully 270ish around there by changing around a lot of stuff. (injector scaling, MAF/MAp tables etc)

Not going to lie, I doubt I am going to PG. Especially since work is really crazy. I am kinda bummed but frankly I don't want to go until the car is working fully. I will head out to RF or BIR at a test and tune day when its done if I don't make it.

Still going to try and make it but not looking good now.

Re: Dave's Evo X Build/The Life of Dave blog
 

You have 8 days left, that's plenty of time.

Re: Dave's Evo X Build/The Life of Dave blog
 

I am going to make you a liar! Your coming to PG, that thing is going down the track if we have to push it!

Plus..Don't think of the PG as just a event, think of it as a 3-day Mitsustyle cruise, with lots of nightly festivities, and driving with a hangover. 2 things we are good at. ;)

Re: Dave's Evo X Build/The Life of Dave blog
 

I'll help with the pushing!

Seriously, you need to just force yourself to have realistic goals, then focus on having fun, even if it's not at 10/10ths level.

Heck, I only managed to get about 60% of the things I wanted to do done on my heap before the PG, but that's not going to stop me from enjoying what a brought to the fullest!

Having slightly reduced fun > no fun.

Re: Dave's Evo X Build/The Life of Dave blog
 

Don't be like Chkmgnt...constant work in progress, then once it's finally done get fed-up and sell it. That's what happens when you don't stop and actually allow yourself to enjoy the car while it's in process.

Re: Dave's Evo X Build/The Life of Dave blog
 

LOL! It's so true.

Re: Dave's Evo X Build/The Life of Dave blog
 

It might be just as easy as getting a check valve for the 2nd pump...but I need to pull the pump out sometime to look at it to get an appropriate one.

I am trying to make it, I have been working on it tons lately, like every night for weeks. But I am starting to run out of steam a bit and work is getting really bad. But we shall see, I could always just run pump gas there instead of e85 just to make it there.

Re: Dave's Evo X Build/The Life of Dave blog
 

Do it!

Working on cars is no fun when you're allready stressed and rundown... that's how mistakes get made.

Re: Dave's Evo X Build/The Life of Dave blog
 

Just run it at lower power, like 350-400, and run the road course instead.

Re: Dave's Evo X Build/The Life of Dave blog
 

Hmmm, interesting...I wouldn't mind doing that. But I still need to get my fuel pressure stuff sorted, then its just tuning.

The car/tune is all jacked up as it was looking for a higher base pressure so I need to do that first.

Re: Dave's Evo X Build/The Life of Dave blog
 

It's so crazy how much time and money you've put into this car and it still has issues..

Re: Dave's Evo X Build/The Life of Dave blog
 

What sort of check valve are you going to use? I have a -6 in/out one way fuel valve that I used on the V when I was having issues with the siphon letting fuel back into the tank.

Looks something like this but a little bigger:

Re: Dave's Evo X Build/The Life of Dave blog
 

Not sure yet, I need to pull the backseat and do some measuring. The two pumps meet at a Y outside the tank, so I am thinking of replacing part of the hose with a check valve.

The size I haven't figured out yet.

Re: Dave's Evo X Build/The Life of Dave blog
 

Oh nice, if you have enough room outside the tank that would be a lot easier than trying to fit the check valve inside the tank.

Is the Y fitting AN or barbed?

Re: Dave's Evo X Build/The Life of Dave blog
 

Here just went and took a picture :)

http://i21.photobucket.com/albums/b2...6/47d67cde.jpg

From looking at this I assume these are barbed.

Re: Dave's Evo X Build/The Life of Dave blog
 

Yea, and that's not much room to work with. Good luck with the fuel issues, I thought most pumps had check valves built into them?

Re: Dave's Evo X Build/The Life of Dave blog
 

Nah in boost I don't have an issue, my car has run over 80psi no problem at full boost.

Its at idle where the issue is, low load in general, before the 2nd pump kicks on. When the second pump runs, there isn't an issue.

I know, its not much room at all, not sure what to do now. I am not sure how big the check valves are, so I dunno.

I think the wally 255's do have a check valve built in. But the pump I am using from blaqops is like a GT500 pump or something strange.

They will be here in the morning. Can't afford to lose two days if I want to make PG, saturday delivery ouch! But MUST FIX EVO!

Normally I do all black/boring stuff as I like stock appearing shit, but they were out of stock until july, so I went balla blue :)

Re: Dave's Evo X Build/The Life of Dave blog
 

Nice! Overnight parts, from Japan*



































*'merica!

Re: Dave's Evo X Build/The Life of Dave blog
 

I am officially throwing in the towel.... (edit: for PG only, not the evo in full haha)

I had to do some work (as in work, not car work lol) over the weekend and that coupled with fathers day = no time for car work.

Also I was going to take friday off and next monday to prepare for proving grounds and recover :) That got axed as work is INSANE right now. So my tune is just not ready at all and neither is the car mechanically and this week just isn't going to give me a ton of time to finish it off.

So I am not about to try and rush the car and go to PG to beat the piss out of it with a tune that isn't really ready, just ain't happening. As much as I would love to go, I want my first track experience to be fun and not filled with agony and a tow home.

Good luck everyone else though :) I will be heading to slippery falls in the coming weeks though.

Re: Dave's Evo X Build/The Life of Dave blog
 

Good decision, but what do you need to do?

I thought it was good to go on pump gas?

Re: Dave's Evo X Build/The Life of Dave blog
 

No, we had to make tuning changes to lower load as I was hitting 330 load at 24psi on pump gas. So we had to do injector and MAF rescaling then it still was hitting too high of load so we were going to do some more rescaling and also raise base idle pressure to add fuel and in turn reduce load further.

Our goal was to have load be around 275 on pump gas where I was so we have room on it for when I do the E85 tune.

Why do we need to lower load you might ask, well there is a hard coded load cap at 360 in the ECU, so you cannot go higher, so we are trying to make sure we don't hit that.

So when we tried raising base pressure is when we found an issue with something (not sure yet) and realized pressure wasn't increasing enough. So until I figure out the fuel pressure problem and get a full retune on pump I wouldn't be ready.

In theory I could revert to my old setup that I had last week and refine that tune a bit, but I don't want to waste my tuners time or my money for a tune that is just temporary. I'd rather fix everything and get it running properly.

Re: Dave's Evo X Build/The Life of Dave blog
 

What a hassle :(

Re: Dave's Evo X Build/The Life of Dave blog
 

Yes, true, but self induced...I didn't need to go this far with the car :)

I have learned that running this power on a 4 cylinder takes a lot of extra care/time to get right...so I am trying to take my time.

I still feel like progress is being made...I'll get it soon I think.

Re: Dave's Evo X Build/The Life of Dave blog
 

You going to slippery rock on a sport compact day?

I'm probably going to take my bike out to one before too long.


Good call on not beating on the car with no good tune on it!

Re: Dave's Evo X Build/The Life of Dave blog
 

Either a sport compact day or test and tune day, whichever is first and works with the schedule. I'd prefer a test and tune day as from what I have heard you can get more runs in and also those have had better track prep's (maybe, lol).

But I am down for whichever.

Honestly my first few runs are going to be rolling the car off the line...for pure trap speeds. then I will take a shot at launching the car. I want to try and get a good trap speed before I break anything ;)

Re: Dave's Evo X Build/The Life of Dave blog
 

So are you still coming to the PG regardless?

Re: Dave's Evo X Build/The Life of Dave blog
 

No sadly, I have like real work I need to knock out, which is why I can't take vacation too.

Any free time I have will be used to work on the car and/or relax.

I need to really catch up on some projects otherwise I won't be able to take the time off I wanted to around 4th of July either.

Re: Dave's Evo X Build/The Life of Dave blog
 

Shitty :(

Re: Dave's Evo X Build/The Life of Dave blog
 

Indeed, no choice though really, work is really heating up.

A ton of our engineers are dedicated to a huge job we have for wood burning power plants and I am stuck being the catch all as I am still in the office.

I am hoping it gets better soon.

Re: Dave's Evo X Build/The Life of Dave blog
 

Don't worry man, plenty of time to hit the tracks this year. Plus racing an untuned car is retarded. Take your time and as long as you are making some progress its all good.
Although I was looking forward to seeing this in action, I can wait.

Re: Dave's Evo X Build/The Life of Dave blog
 

^Got a GoPro Hero2HD now, so I will have plenty of film of when I finally go :)

Re: Dave's Evo X Build/The Life of Dave blog
 

Nice, I was looking up track days and 7/13 & 7/14 seems to be the next open days. Well that I can go I think the 7/1 weekend has some too.

Re: Dave's Evo X Build/The Life of Dave blog
 

7/13 and 7/14 seem like a good weekend to shoot for, gives enough time to make sure its running tip top. And gives me time to get a helmet...I want to go try some on.
