Re: beaterX project thread
 

Heh, no WOT b/c of the MAF issues but I certainly gave it a bit of boost and rpm :)

Re: beaterX project thread
 

scheides, did you replace your main bearings or main studs or are they stock? I'm not sure if that has to be done when you unbolt the mains.

Re: beaterX project thread
 

That's been argued many times, the whole "proper way to break in an engine" thing. I know some super knowledgable people that will say one way and one will say the other, I don't think there's currently a 100% proven method as compared to the other.

Re: beaterX project thread
 

Re: beaterX project thread
 

Bearings are ACL Race, not sure if the main studs were replaced or not, I'd have to ask MAP. Rod bolts are L19's though :)

Thx for the link! I've read just about every one of the big dsm/evo shops break-in instructions (including these) and I think AMS is spot-on here and its about what I've done. Partial throttle pulls are fine since the existing tune is mostly fine, and its rare that I cruise on the freeway for more than a few miles anyways.

Got about 60 miles on it now, no leaks yet and it drives/idles great! I can't wait to start tuning this thing :D These cams are awesome, the car will idle just fine at 900rpm and roll down my alley in first gear at 1000rpm no problem.

Re: beaterX project thread
 

LMK when its getting tuned! i'm laid off for the winter so i might just have to roll up there in my winter beater. Maybe we can throw her on the dyno for shits, and gigs :D

Re: beaterX project thread
 

I like the hard break in method. It's been out standing in its field since then. No problems or oil burning or anything.

Re: beaterX project thread
 

You would drive 2 hrs to watch a dyno? :leghump:

Re: beaterX project thread
 

I honestly have nothing better to do. im so fucking bored not being able to work i gotta fuckin get out of the house.

Re: beaterX project thread
 

^Shit, I would of had you clear my drive way and then you could of dismantled my DSM for fun!.

Do you have dyno time scheduled?

Re: beaterX project thread
 

Not yet, prolly sometime in January. Break-in miles and a little street tuning first. Shane's out of town and then I'm out of town over the holidays.

Re: beaterX project thread
 

LMK next time you need some help!

Re: beaterX project thread
 

320 miles on the odometer and I am grinning from ear to ear! No leaks so far, but my fingers are still crossed. The car has jumped right back into DD duty which has served well for doing vacuum pulls, some traffic w/ plenty of stopping/starting to break-in the clutch, and getting miles on the thing.

Off-boost the car feels SO much better than it ever did before, even on the stock turbo. When I first started driving it, anything over about 5psi under 3000rpm would cause the car to buck and backfire; I ended up pulling out some mivec on the intake cam and that seems to be all but gone. These Kelford 214-b's are some of the bigger cams you can get for the X but man they sure idle nice! I can leave the car in 1st gear and idle down my alley w/o any jerking and only sometimes will the car get into a small dance around 900rpm and lop lop lop.

I have boosted to a peak of around 16psi so far and then peddled the throttle to keep it from going higher. The car feels like an animal and just wants to rev rev rev! Even at part throttle 6500rpm comes up in no time in 2nd and 3rd gear.

These miles have been my first experience with this car in the snow. We got like 17" last weekend and another 5" last night and I have to say I am *insanely* impressed with how stable this thing is. The combination of the S-AYC and a little more weight is just seriously impressive when driving at the limit. Any heartbeat/instant that I got that deep 'oh fuk' feeling that I got as I careened towards that ditch in my evo8 last spring is immediately followed by pure confidence as the car doesn't want to over-rotate or understeer at all--it seems to know whats right and stay on the trajectory I will it to be on--even if its sliding sideways at 30mph and facing a curb!

I'll put a few more miles on it this week, then the car will be at MAP for a few days while I'm out of town next week--they want to build a heat shield for the rear CAS (to go with their tubular manifold) and maybe try out a few other things.

When I get back I'll do an oil change, compression test, and I'm thinking about pulling the valvecover to double-check the clearances on the valve tappets. There is a slight tick when the car is cold and I want to make sure everything is perfect--then a few more miles and it'll be time for some boost!

Having my car back and being able to drive it is the best xmas present ever.

Re: beaterX project thread
 

Glad to hear break in is going well!

Re: beaterX project thread
 

Awesome news Scheides, I am happy its all working out...best feeling ever when stuff starts to come together!

Re: beaterX project thread
 

I like the stock wheels back on it, looks good! Looks unScheidesish though :)

Re: beaterX project thread
 

Woot!

Re: beaterX project thread
 

Looking good!

I got a ride last night to "quick" get pizza... and it is very impressive in its snow abilities. I love how the IX is in snow... but this is a step above even. Makes me a little jealous!

Re: beaterX project thread
 

Agreed

Re: beaterX project thread
 

^word. Congrats on having it back, but you probably shouldn't be driving it to its limits just yet.

Re: beaterX project thread
 

Nice! Glad to see everything is going well!

Re: beaterX project thread
 

1000 mile update! Well, 960 miles actually. Close enough, it'll roll over 1k tomorrow's commute. I changed the oil at ~530 miles, tish late b/c I had to give a buddy a ride home from work, and he lives in IGH, like 25 miles out of my way. It hadn't burned a drop of oil. I have continued to do vacuum pulls where I can and have done some light, 50% throttle pulls up to around 16psi and the car feels amazing.

MAP had the car for a week or so over xmas/new years (sidebar: best xmas ever? Got great gifts, a job offer, quit my current job, flew to vegas and then got stuck there for New Year's eve. Win!) for some prototyping their o2 dump downpipe but didn't manage to get the 4th bolt in holding the mani to the turbo. I am still a teensy bit peeved but meh, I will survive. Doesn't look like its leaking (yet). I'll find time to put it on sooner or later, but the last time I tried it was an impossible wh0re, even with two people wrenching with all their might.

Clutch is all broken in and the cams seem to idle almost perfect, they sometimes jerk ever-so-slightly when in traffic at 1500rpm but otherwise i can leave it in 1st or 2nd and no throttle input and the car does not buck what-so-ever! I love'em and can't wait to tune them for power.

MAP's recommendation is to leave dino oil in the motor until 1500 miles before switching to synthetic but others say that by 1000 miles the motor is where it's gonna be. I might as well wait a few more hundred miles before switching because with the shitty roads and Shane's schedule, I won't be ready for WOT for at least a few more weeks.

Now, the interesting part! I took a wrench to the car for the first time in a month tonight. Still no leaks that I can find (although Kyle@MAP said he saw a drop of coolant on that one stupid pipe off of the water pump) but I decided to swap in a fresh set of spark plugs, do a compression test, and yank the valvecover quick. I had been using lomker's HKS plugs he had problems with (do you still want these back or should I just give you cash for them Mike?), but interestingly enough the new OEM plugs I got at the dealer were pre-gapped to .021, quite tight IMHO (that's what she said).

Also did compression test: 155 158 154 153. Holy hell! When I got the car I tested it at about 135 across the board. These are supposed to be stock compression pistons, and from what I had read before about 140 is normal. Not sure what it means but I'm kinda pumped that the numbers are strong. If for some reason its kinda high b/c the compression ratio is off...well, I was thinking of going E85 anyways :)

Next I yanked the valvecover. I wanted to double-check the valve-tappet clearances before deciding to go buck wild with this engine. Mixed feelings about what I found. When I was done putting the motor together one of the intake tappets was .001" out of spec at .010 (spec is .008 +/- .001). It was on the loose side, I had it up to here with the whole car and said fuk it. Now it's at .012, and it probably explains why the valvetrain seems a tish noisy on a cold cold startup. Once warm it is not a problem, so I will consult a few people as to how bad this really is and likely just say FUK IT!

So so so so excited to really rip on this thing I cannot tell you! But, I'm in Minnesota, its cold as shit here now, and we are having one of the snowiest winters on record. Having fun none-the-less! :D

Re: beaterX project thread
 

Fantastic update Scheides! Good to hear that things are going great with beaterX!

Re: beaterX project thread
 

Very nice.
E85 time join the goodness!!!

Re: beaterX project thread
 

niiiiiiiiiiiice update

Re: beaterX project thread
 

Thanks but still a twinkle in my eye. It'll get a basic pump gas tune first and then who knows what will happen in the next few months. I have a new job with much better access to the good stuff, but the car would need fuel pump, injectors, and maybe a maf/intake upgrade at the very least. I'd be jumping right into needing a bigger/beefier fuel system, not just a wally and some pte 1000's for a cheap upgrade. We will see what happens come spring :)

Re: beaterX project thread
 

Awesome that the motor is so healthy man!! So, what mods do you have since last tuned other than the built motor (same compression right?) and the cams then?

Re: beaterX project thread
 

I need a ride in this thing in snow mode. Rosey was raving about it when he visited me at work today!

Re: beaterX project thread
 

Either way. Those plugs are fine on pump but I had weirdness on E85.

Re: beaterX project thread
 

Built motor, ported head w/ +1mm valves, Kelford cams, Buschur FMIC. Also the last time I was on shane's dyno I did not have the tubular manifold, so it will be verrrry interesting to see where it lands. I am trying HARD to tell myself to tune it very conservatively since its still winter, so if I can do that and see 360whp on pump I will be pretty happy. I still have dreams of 400 on pump, but with snow tires and nowhere to actually use it keeping it conservative is prolly the way to go. I can always turn up the boost and timing for the spring dyno day :)

A few x-factor thigns, bcs and higher rev limit. I have the mbc/bcs hybrid boost control setup now which should eliminate boost taper up top. Also, in both pump gas and race gas dynos last fall with the rev limiter set at 8000 power was still climbing at the rev limiter. With the built head, I'll be able to rev it much higher if I want to, so there may be some peak number gains there too. In the end both of these are only top-end gains but who knows what they might be, 5-15whp? Dunno, we'll see I guess!

Re: beaterX project thread
 

Those new Jay racing or DW pumps would do you just fine.

Re: beaterX project thread
 

Yea, and the crazy thing is that even on pump gas I feel like I might be at the absolute limit of the DW800's so I thought about pulling the trigger earlier than later on the fuel pump. This would hopefully get me a little bit more headroom with them. In the end keeping the stock fuel pump in there will (hopefully) force me to keep the tune conservative.

Re: beaterX project thread
 

360 on pump with a quick spooling turbo would be nuts on teh corn. Heck, I wish I could make 360 on pump lol.

These 4b11's just seem to love to rev out like crazy huh?

Re: beaterX project thread
 

360 on pump = :drool:, sadly I'm a few generations back and I think 260whp on pump would be where I would have to aim and fail at.

Fuck a conservative tune, well not a safe tune but you have a built motor and head so why not make the power it can, if want less turn it down.

Re: beaterX project thread
 

You do realize he drives this every day and beats the piss out of it regularly, right? A "ragged edge" tune is not exactly ideal, even with his built bottom end.

Re: beaterX project thread
 

I knew someone was gonna take that the wrong way.

I'm saying its a built motor I believe built to handle 700whp, so he can make 400-500 and be ok.

I think by keeping the stock pump he won't be keeping the tune conservative but more so the power levels, which he can control by just turning the boost down or having a hi-lo tune.

Re: beaterX project thread
 

You always have such worth while updates Scheides, lol.

Awesome to hear man, I would assume you will hit 360whp not problem. a pump gas Fpred hit just over 350whp on Shanes dyno with a stock motor so i would assume you will easily hit that goal. Maybe even 400whp on pump...i think its possible but we will see I guess.

Re: beaterX project thread
 

Why wouldn't a built 4G? You guys rarely build your bottom end so I suppose that's why people keep the revs down.

Re: beaterX project thread
 

Heh all I meant was for this initial tune I'm gonna gun for about 25-26psi, see what it does with some timing and then go from there. If it responds super awesome then yes I'll be tempted to bump it up to 28 or so and push it a bit to see what it does, but at this point I just want a good solid base tune on there for daily abuse and then depending on what I do in the spring I'll turn up the wick a bit.

The head dynamics on the 4G63 get worse and worse the older ones you get. It's way more common, to get good torque and then peak power at 6500-7000rpm or so, then fall off. Unless of course you have a big turbo with a big hotside.
