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 :)

Very nice.

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.

Nothing beats a MBC for ease of use and reliability.

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 :)

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.

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.

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.

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...

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.

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

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

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.

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

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.

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.

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. :(

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?

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