beaterX, 2.5 turns of the wga
 

Just did this on my new beaterX! 2.5 turns in on the wga and 1/3 down on the MBC yielded this:

Comparator numbers:

Should have left the MBC alone I guess, peak did go down a tish, but with the mods on the car, 26psi peak is plenty for now:

Lastly, the data, for anyone that cares:
http://scheides.com/misc/pics/evox/E...t-wgacrank.xls

This was done on the same road, same conditions, within an hour of each other. Perfectly flat, started run in 3rd at ~2000rpm and WOT till ~7000.

The car still has the rusty exhaust and stock cat in place. I put in mlomker's used aFe drop-in the other day and decided I should try this next. Arguably worth it :)

Re: beaterX, 2.5 turns of the wga
 

Very nice.

Re: beaterX, 2.5 turns of the wga
 

I think you'd do better with an EBCS than an MBC and fiddling with the other parts, but if it's stuff that you already had lying around then it's good gains for cheap.

Re: beaterX, 2.5 turns of the wga
 

Nothing beats a MBC for ease of use and reliability.

Re: beaterX, 2.5 turns of the wga
 

Yup sticking with the mbc for now. I'll play with the ecu boost once tephra gets some of his hacks on this platform. The mbc was already on the car and the wga crank cost me 20 mins :)

Re: beaterX, 2.5 turns of the wga
 

I've never heard of an EBCS user having overboost issues during temperature changes...that's an MBC problem. If the ECU is great at managing that sort of thing then I don't see the point in remaining old-school.

Re: beaterX, 2.5 turns of the wga
 

I'm telling you now, it is an issue, I promise :) Maybe not for you, but it happens. Weather can affect MBC's as well, just not as much. A lot of guys mount their MBC's (and BCS solenoids) near their radiators to try and cut down on the variances weather can cause.

Either way, this mod isn't about MBC or BCS, its about the turbo flowing more by keeping the wastegate closed tighter; it's not holding a ton more boost anywhere, but making more power.

Re: beaterX, 2.5 turns of the wga
 

Have you actually tried all the different forms of boost control or just read about the online? I have. I haven't remained old school, I've gone back to old school after giving the newer/fancier/more expensive methods a chance. With my MBC mounted to the radiator fan shroud I see 1-2psi variance max due to weather changes; I saw far more than using using ECU-controlled boost. My car is also more responsive and boost hits harder/faster with a MBC. Put one on your car as a test sometime and compare the boost curve, I think you'll be quite surprised.

Re: beaterX, 2.5 turns of the wga
 

I look forward to doing such experimentation once the bigger mods wind down.

I'll also say that I only read the X forums and have never pretended to know shit about 8/9's. You'll be basted if you try to argue in favor of an MBC on a X forum. The X has a different ECU and I'm sure scheides will uncover a lot of interesting things as he continues exploring...

Re: beaterX, 2.5 turns of the wga
 

Scary, a bunch of newbs regurgitating info on the internet :) My guess is most of those guys only read something somewhere and have no actual real-world experience (must like yourself yet you still make claims regarding which is better).

With more experience you'll learn there is quite a difference between what you read online and reality.

Re: beaterX, 2.5 turns of the wga
 

Oh yea, I own one of those now, maybe I should check that site out. :P

Re: beaterX, 2.5 turns of the wga
 

Wow, I can't imagine with all that shit around why forums and the car scene in general are becoming more horseshit.

Re: beaterX, 2.5 turns of the wga
 

I discussed this with Kracka not too long ago, but Sport Compact Car did a test between the popular MBCs and EBCs at the time (2004 or 2005?) as to how they handled boost onset (spiking) and how they held boost throughout the RPM range. The MBCs outperformed the EBCs by having the smallest spikes at boost onset and holding boost better to redline. Granted, this was a few years ago, but the general idea between the two devices is entirely the same.

Re: beaterX, 2.5 turns of the wga
 

Nice work Scheides! Gotta like making more power on a little less boost! Hows having MIVEC treating ya?

Re: beaterX, 2.5 turns of the wga
 

Ah, yes...newbs like Bryan @GST, Chad @CBRD, and other people that know a lot less than the hobbyists on this *forum*. scheides cross-posts much of his stuff on national forums as well.

If you're talking about standalone EBC then we're talking about different things. An EBCS is a replacement boost control solenoid, controlled by the ECU (aka 3-port). I certainly wouldn't install a standalone on an Evo.

Re: beaterX, 2.5 turns of the wga
 

I have used an Apexi AVC-R, Shanes MBC, and a Forge MBC, by far the best one i have used has been Shanes. The AVCR sucked ass in my opinion. EBCS FTL.
Anyways, good shit Scheides keep it coming i expect to see 500 AWHP at dyno day. or you are no longer the site admin and get your post count stricken down to 1.

Re: beaterX, 2.5 turns of the wga
 

Scheides,
Awesome work! MBC, EBC, Boost control, smoosh control, the boost looks excellent what ever it is.
Mine is attached for comparison purposes this is bone stock tune vs RS Motors tune, yours looks great in comparison for the boost spike.

Re: beaterX, 2.5 turns of the wga
 

What he is saying is that all you are doing is regurgitating information that "newbs like Bryan @GST, Chad @CBRD" post online. You have NO real first hand experience yourself.




Anyways, Looking good Scheides! I want a ride in this thing at dyno day, I never did get a ride on your VIII. :(

Re: beaterX, 2.5 turns of the wga
 

I am fully aware of what Bryan and Chad have done and do, my guess is I knew who they were long before you decided to even "get into" cars. Goodhart is right, my point is that you have zero first-hand experience and can do nothing more than attempt to understand information you've read online and regurgitate it. I also know that Scheides cross-posts a lot of his stuff on the national forums and if you'll notice I have as well. What's your point? You should also take a look at how similar ECU-controlled boost and any off the shelf pre-packed electronic boost controller is. Here is another question for you: Have you ever actually used a MBC? EBC? ECU-controlled boost? I'm talking actually used, not just drive a car with one. Have you ever installed them? Do you even know how they work?

Re: beaterX, 2.5 turns of the wga
 

What is so magical about a X that it needs an EBC?

Re: beaterX, 2.5 turns of the wga
 

From a guy that doesn't change his own oil? MLomker, I'm sorry bro but I would be surprised you've even gapped a sparkplug and installed them before, let alone install or even so much as turned the knob on a MBC. I'm just sayin it how it is man. I don't type anything that I wouldn't tell a person straight to their face.

Also, stop copy-pasting what others post on EvoM and the X forums as if you really know and/or have experience with any of what you are talking about. It is very misleading to others. They may actually think you know your ass from a hole in the ground.

but OMG it is the unicorn of all cars!! You couldn't possibly use technology from lowly little cars built in the 1990's on this car sent from god, that no average man dare work on himself.





/of my opinion

Re: beaterX, 2.5 turns of the wga
 

LOL this thread kinda 'sploded into a whole secondary discussion about mbc's vs ebc's...end of the day (as I said before) this mod would work with either. People are obviously pretty passionate about which form of boost control is 'better' and and of the day, it is 100% up to how well the system you have works with the setup you have, end of story. I have played with MBC's and EBC's on dsms, evos, vw's, audis, and porsches, and guess what: you use what works best for YOU on your car.

I'll play with the ecu-boost on this thing soon enough, don't worry :)

Re: beaterX, 2.5 turns of the wga
 

And you with your 300whp factory freak gah! Stop making me jealous! When I actually get a full tune on this thing, we'll see what it'll do. For now, its a good solid basemap on a car that needs TLC all around, including under the hood :)

Re: beaterX, 2.5 turns of the wga
 

Ah, it reminds me of the good old days of last month. Tempers flared, rank was pulled and people got burned.

I know it's about the furthest mitsu from an X (save for being the OG donkey kong of mitsus), but my boost is controlled with a greddy profect b-spec 2, and it's really cool when the gain isn't set too high, aha.

Re: beaterX, 2.5 turns of the wga
 

^Profec B FTL, is flakey when running man boost levels.

Re: beaterX, 2.5 turns of the wga
 

I like my EBC, "Boost Box" for the SRT4. Works awesome, boost by gear, rpm, a lot of tweaking you can do, and uses the stock wastegate solenoid. Would never think of going back to a MBC on this car.

Re: beaterX, 2.5 turns of the wga
 

The same kinda magic that requires a OEM BOV from Japan yo!

I've USED, INSTALLED, and messed with all boost controllers, except ECU-controlled boost control solenoids, like AEM EMS can use. From my experience, MBC's are the most straight forward, easiest installed, easiest set-up, most reliable (depending which brand you get) and best controlling of all boost controllers. Electronic ones are only as good as the software that drives them, and as we have all seen, sometimes..the shit just doesn't work.

Re: beaterX, 2.5 turns of the wga
 

Let's see if Kracka bans me this time for disagreeing with him.

This is my first turbo car. As mentioned in my own thread, I was a garage peon for 2 years out of high school...oil changes, spark plugs, tires, hoses, belts...basic stuff. I'd do all of that stuff if I had a garage but I don't. Hauling that crap over to a friend's house is too much trouble for what it costs.

Re: beaterX, 2.5 turns of the wga
 

Sorry, but driving to a friends house to change your plugs, tires, wheels, hoses or belts is NOT more trouble then what it's worth. We charged over $120-$240 to change fucking spark plugs at the dealerships, you telling me shoving a box of 4 plugs in your car, and driving a few miles to a friends house to change them is trouble?! What gas are you running that costs you more then that to drive somewhere? VP Import 120!?

Re: beaterX, 2.5 turns of the wga
 

I have changed all those items he listed but tires on the side of the road before or parking lots.
If someone needs space I usually have a driveway spot or can clear a garage spot for big work.

Re: beaterX, 2.5 turns of the wga
 

LOL GOOD GOD guys grow up! Enough about MBC's, EBC's, and where to change your oil, I don't give a shit! I tightened the wga on my mostly stock car and picked up a few whp. Neat eh? The end. :P

Re: beaterX, 2.5 turns of the wga
 

Why not? It controls boost just the same, an electronically controlled solenoid. If one performed better than the other then I see no reason to use it.

Re: beaterX, 2.5 turns of the wga
 

Boost control discussion. Reminds me of the ford vs Chevy discussions...lol

BTW.. x's are the suck in Autocross.. right Matt? ;)

Re: beaterX, 2.5 turns of the wga
 

Double post ..sorry

Re: beaterX, 2.5 turns of the wga
 

I'm never driving one again.

Okay, maybe... ;)

Re: beaterX, 2.5 turns of the wga
 

I seen your tightened wga and raise you a pulled WG line and picked up an buttload of whp. Pretty badass eh? thats I roll. Fin. :sport017:

Re: beaterX, 2.5 turns of the wga
 

^ true story. WG does all the action.
