I think 2k2S4 (mpwolf)'s server is being overrun at the moment by everyone trying to see the diagram.

Since there seem to be a lot of questions on how N75 vs MBC vs Both affect boost, I drew this up... - Mark P 2004-03-19 08:48:12 (15006 views)

Another option is just to run a EBC (like I'm doing now) - Joshua (wishbone) 2004-03-19 14:17:14 (1493 views)

What chip software are you running? - Verrückt 2004-03-19 14:27:15 (717 views)

I'm running GAIC X, so I don't see any deviation codes, but I don't run much higher than 18-19 PSI - Joshua (wishbone) 2004-03-19 14:28:28 (848 views)

would a mbc in parallel control spikes up high as well as down low? - shl rider 2004-03-19 11:41:31 (865 views)

Whenever the boost reaches the set value of the MBC, the MBC bleeds off the extra - Mark P 2004-03-19 11:52:48 (864 views)

Everywhere ... When used in parallel, it would control the upper boost threshold - jbear@work 2004-03-19 11:45:05 (755 views)

That is correct. That is how mine is set. - DAP 2004-03-19 11:46:27 (607 views)

damn... looks like I need a MBC - Why would one not do it ? - sfored 2004-03-19 10:51:30 (767 views)

Read Mark's post. It depends on what you are trying to accomplish. - DAP 2004-03-19 11:01:46 (2559 views)

If you don't have boost spikes and you aren't doing any fuel upgrades, the chip by itself is fine. - DAP 2004-03-19 11:08:02 (586 views)

alright sounds good. thanks for clearing some stuff up for me !!!!!! - 2000s4biturbo 2004-03-19 11:10:05 (504 views)

<bowing graciously> :P - DAP 2004-03-19 11:02:42 (459 views)

BTW, I think boost builds quicker no matter which way you have the MBC set up. However... - W0LSC0D(Anti-Rice) 2004-03-19 09:49:12 (894 views)

I agree. - DAP 2004-03-19 10:37:51 (527 views)

Awesome representation Mark! - Verrückt 2004-03-19 09:47:50 (462 views)

So which is better? In you opinion, of course ;) - swinmachine 2004-03-19 09:42:28 (531 views)

Totally depends on your setup and what you want to accomplish. - W0LSC0D(Anti-Rice) 2004-03-19 09:44:49 (764 views)

Is it correc to say that MBC alone will yield the most power because... - Swank4 2004-03-19 10:18:16 (775 views)

Peak power may not be much higher, but it will yeild more area under the curve... - Verrückt 2004-03-19 11:16:19 (656 views)

Yeah, that is why I say it depends on your objective. I want power AND reliability. Therefore.... - W0LSC0D(Anti-Rice) 2004-03-19 10:32:49 (695 views)

Unless you've got fueling upgrades, you probably want the MBC in parallel with the N75. - DAP 2004-03-19 10:39:57 (695 views)

Okay, from now on, you are in charge of answering questions! We end up saying the same thing :) - W0LSC0D(Anti-Rice) 2004-03-19 10:40:49 (514 views)

I'll accept that awesome responsibility! - DAP 2004-03-19 10:44:43 (487 views)

"What's better for the engine" They are all fine. - W0LSC0D(Anti-Rice) 2004-03-19 10:35:20 (613 views)

Are boost spikes EVAR good for the engine? - reefer_bob 2004-03-19 10:32:43 (593 views)

Very nice simple explanation! Why didn't I think of that!? - W0LSC0D(Anti-Rice) 2004-03-19 09:24:32 (511 views)

Great info - a side note to others about the blue line - it can still taper down - DarinS4Turbo 2004-03-19 09:23:51 (729 views)

Good point Darin. Closed wastegates on K03's will taper down to 15 psi at redline. - Verrückt 2004-03-19 09:45:53 (824 views)

Exactly! Here is an example of a k03 car running MBC only and tapering.... - W0LSC0D(Anti-Rice) 2004-03-19 09:27:53 (1117 views)

so should we run MBC's? - 2000s4biturbo 2004-03-19 09:14:15 (594 views)

Absolutely no need if you happy with your current boost delivery. - W0LSC0D(Anti-Rice) 2004-03-19 09:47:12 (665 views)

In parallel with the N75, sure wouldn't hurt it seems.... - reefer_bob 2004-03-19 09:18:50 (775 views)
