I go a point lean without a shield on the intake but my O2s are disabled so it can't adjust.

410 on pump would be pretty crazy.

Very nice Scheides, glad everything is working out for you. Can't wait until you switch to E85, this setup will shine even more!

You going to rev to 8k on this setup always or just for now?

scheides 05-09-2011 10:23 PM

Re: beaterX project thread
 
8000 is plenty for the street, I'll prolly do 8500 for the track, maybe higher as needed. Revs and engine longevity are directly related so part of me wants to keep the revs down but the other part of me wants to just use what I've built for things of awesome :D

Murlo26 05-09-2011 10:26 PM

Re: beaterX project thread
 
You are a stronger man than I for resisting the revving...your car also works still so you might be on to something :)

The black really needs the extra revs though I think makes the transition between shifts way way better.

Does the bbx stumble at all shifting at 8k? I know my red almost stuttered at the stock rev limit.

Edit: I usually shift sooner than that, now that I think of it. It's hard to explain but it has always 'felt' faster to me to upshift than to wind it out. I have a natural tendency to upshift as soon as the dyno chart flattens.

Wow, I never thought I'd see the day when scheides had a built motor, 1680's, etc haha!

Can't wait to see what this bish does on E85!!

Re: beaterX project thread
 
Nope, BBX I can shift at 6500 and the car is still plenty fun/fast. Half of the fun of having a super wide powerband though is just cranking on it and reeeeeeeeeeeeeeeevvvvvvvvvving it out faster faster faster woaaaaahooo! So yea I get what you mean revving higher.

The one thing I really want to work on the next time I go to the drag track is revving first gear higher. I think I could have picked up another tenth and with the extra power now it'll take some getting used to, but I have the valvetrain to do it now so why not. Also I was always scared to rev it too high for autoX but with the low gearing of the X I was sometimes hunting for which gear to be in; I think having a setup made to rev higher will make decisions like that easier, not to mention having more down-low torque thanks to the cams!

Heh, all I want is a healthy motor, a safe fuel, and a good tune. I don't think my priorities have changed that much, just those times ya know...they are a changin' :P

Re: beaterX project thread
 
Well I think I've settled on 1.39*stock maf for about perfect scaling for my car and the 3.5" maf. Ironically:

area of circle: pi*r*r
inner diameter(stock): 2.8" (r=1.4)
inner diameter(primo): 3.3" (r=1.65)

area (stock) = 1.4*1.4*3.14 = 6.15 sq inches
area (primo) = 1.65*1.65*3.14 = 8.55 sq inches

conversion ratio (primo/stock): 8.55/6.15= 1.39

Others had told me 1.5 so I went with 1.48 to start....gah.

Anyways, been playing with boost. Goal is to peak to ~26psi and hold at least 25psi at 8000rpm. It's *not* perfect, but I'm getting there :) This is after about 3 revisions of testing.

http://scheides.com/misc/pics/evox/e...fter-35maf.jpg
(note: these pulls were started around 5000rpm, just for testing upper rpm boost...full pulls I will do when road conditions allow)

This is using my hybrid setup: hallman MBC inline with pierburg 3-port bcs. Seems to be working nicely :)

The back straight at BIR could be run in 3rd to redline or it's a very brief shift into 4th before downshifting again. I usually upshift since my issues have made me disinclined to really thrash on it. I suspect it'd be faster there to let it rip, though.

So are you running the MBC from the 3 port to the wastegate? In an attempt to get more WGDC that way? Just trying to understand. I was considering doing that to try and hold some more boost after 7600rpms...or however I would need to set it up I guess, never got around to looking into it.

Re: beaterX project thread
 
Looking good man. So you're running 26-27 on pump gas? or has the E85 conversion started?

scheides 05-11-2011 10:33 AM

Re: beaterX project thread
 
It's still plumbed exactly like this:

http://mitsustyle.com/forums/showthread.php?t=28224

BCS goes between the outlet of the MBC and the WGA. The sole purpose of this is to help eliminate boost taper that a MBC sees, and *hopefully* more boost = more whp but that is not always the case. We shall see come saturday :D

Not till next week, the new injectors are still in a box on my workbench. Yes this is just pump gas.

So, Primo came through for me with a last-minute surprise for the dyno day:

Introducing the Primo Performance 2.75" Evo X LICP
http://www.scheides.com/albums/evox-...4123.sized.jpg

This is the coldside pipe on the X, wrapping around to the TB
http://www.scheides.com/albums/evox-...4124.sized.jpg

The stock pipe is decent and I made great power on it, but I can't help but notice there's some subtle niceties that I really really like about this new, slightly bigger and smoother-bending pipe:
http://www.scheides.com/albums/evox-...4126.sized.jpg

Mates right up to the 2.75" OD of the TB:
http://www.scheides.com/albums/evox-...4127.sized.jpg

Utilizes stock mounting bolt w/ stock rubber mount:
http://www.scheides.com/albums/evox-...4128.sized.jpg

Fits perfect! Comes with t-bolt clamps:
http://www.scheides.com/albums/evox-...4130.sized.jpg

Got the factory air scoop to fit too!
http://www.scheides.com/albums/evox-...4134.sized.jpg

Driving impressions:
holy hell, I honestly wasn't sure it'd make much of a difference. I was plesantly surprised to say the least! Off-boost in the 2500-4000rpm range the car feels more responsive and when boost kicks in I feel a definite bump in torque in the midrange!

The car feels great overall and while the boost curve is still not perfect, I'm able to hold 26psi at 8500rpm. PS I raised the rev-lmiter :)

See all tomorrow at DB!

11am too early? LOL whatever dude!

I will go when its my turn, whenever that happens to be. Might be at 11, might be at 3, might be at 7pm, who knows.

11am is early when you are up until 3am or later.

I'll have to do an early friday tonight...must see dynoing.

There might not be any cars left to dyno by then, but lunch time is for sure and E85 conversion is a maybe:)

Re: beaterX project thread
 
1680's installed. Physical install was a cinch, took maybe 20 minutes; the fuel rail is right on top/front on the X so this was completely painless.

Initial settings I had from the guy I got them from didn't work worth a crap, the car idled at 8:1 and sputtered and died. Tried some more settings published on evoM with again, no luck. Then I realized that mrfred had posted some values from a car he had done with a cobb AP.

2.625
1.395
0.825
0.660
0.600
0.555
0.540

he posted E85 scaling: 943
Pump scaling I guessed, ~1.3*943: 1329

Last summer tephra figured out that the original algorithm used to display latencies and I could apply that and use mrfred's values for the cobb car. (link: http://forums.evolutionm.net/evo-x-e...hm-change.html) Still no luck. Car starts and runs good for a few secs above 2000 then as soon as it goes below 1500 it just goes pig pig rich again.

My logger is goofed up for some reason, but I'm thinking that the ecu simply won't drop pulsewidth low enough, so I applied tephra's minimum IPW hack:
http://forums.evolutionm.net/evo-x-e...ion-patch.html

Dropped MinimumIPW down one notch from .040 to .032. flash, start car, bam, fukin starts perfect, revs to 2000-3000 w/o any stumbling or issues, and it idles like a champ. Took the car around the 'block', initial short-term fuel trims look fine so I give it a few brief wot runs, just around 4000, into a little boost to check afrs.

Sad news, wideband in the car is flatlined at 0v again. No knock on the wot runs though, so I guess I'll just be driving around nicely and checking fuel trims until I get a new sensor.

*edit* hit the recalibrate button for the LC-1 and it's come back to life. I'll be testing this setup a bit until the tank is dry....then it's time to sell my soul to the corn gods :P

Oh also, changed the oil today. 3100 miles on this oil, the car didn't burn a drop. I don't say it often enough, but I want to thank MAP for a stout shortblock and DB Performance for a solid head. And while I'm at it, CBRD Speed Factory for such a bad-ass 100% stock-appearing turbo!

http://www.scheides.com/albums/evoX/...inal.sized.jpg

We'll see how well it holds boost once we turn it up to ~30 for the e85 tune.

Hell hath froze over! Hit play on this video before you scroll down much farther:

http://www.youtube.com/watch?v=Db1s-eV-Bd0&hd=1



















http://www.scheides.com/albums/evoX/evox_e85.sized.jpg

Car was on E and flashing the gas light leaving my garage, drove about 5 miles and then filled up. I fired it up on the pump gas map then after about 20 seconds switched over to the e85 scaling on the alt-map. Drove around after filling up and dialed in injector scaling, settled on ~850 which still seems way low to me. Stopped by jim's house and we went for a rip. I logged and looked, the car is fine in midrange but lean up top, like high 12's. Gah! Also I smell fuel, alcohol fuel...fuel rail is leaking wtf!? Oh, one of the bolts is loose!???!

Yea, minor freak-out moment, but after closer inspection, I realize what I had sorta thought when eyeballing the new injectors: they are taller than stock. The stock spacers were just free to spin and the whole fuel rail was tweaked leaning forward, sitting cockeyed on the injectors. So I snugged it down for the drive home and then checked my garage for just the right spacer. I believe these are old metal center sections out of a 1G shifter base bushing or something, but they fit great! They're metal though, so I hope it doesn't come loose. Also I hope the rail not being cock-eyed helps flow and helps richen things up. I will report back!

Initial impressions--the car freaking rips on e85! I left boost alone for now, ~26psi across the board, and after initial logging, I added 2° of timing, it just hits 15°*at like 7500 or so, still very very mild but the car just feels smooth and powerful and absolutely no knock.

Re: beaterX project thread
 
The fun comes a few months from now when you realize that you haven't given a thought to what fuel from where, knock, different "pump gas" tunes and boost settings because that shit just doesn't matter. :D The car is always set to "kill" for the summer and you never missed an opportunity or worried about pesky things like knock or bad gas. The biggest worry will be "Where is the nearest E85 Station?" which sadly you will memorize about 30 of them before year end and you also start to wonder if the MIL light is broken since it never ever flashes again. :D

Car felt good, can't wait to see that thing run 30+psi and more timing. 475+hp anyone?

I know my compression is costing me a little power but if he managed another 25 then that'd be impressive. I don't think the BBX has the breath.

Thanks man! You've been pushing the stuff for years and while I ran I for a while on my 8 it was through winter and always a pita just due to circumstance. I hope it stays convenient for me because as of now it seems way way worth it!

Sorry man, this was literally a fuel stop for me, iv been planning for a while and done it so many times with others, the process was easy. Off work at 6, dinner, fill up, drop off stuff at jim's (I've had a few of his tools since last fall!),around the block and then back home. There will bs plenty of tuning and other fun time, don't worry :)

No prob. So far it's been dead easy, the X is really really easy to tune and a lot of base values are already out there. I'll certainly be posting mine once I'm done.

Congrats on the conversion scheides! I will be making the switch to corn hopefully within the next day or 2 :D
