manual boost controller

[IanS13]

how do i install a manual oost controller do i just put it in the vacuume off the turbo then the oth end into the waste get inlet port.

[WDRacing]

Yep...

[IvanAtSPRacing]

yes, but make sure you put the right end towards the turbo

That makes baby Jesus cry.

just because am to afarid to install this i'll just get the greddy i have spent so much money already i migh as well spend a next $400 for the damn boost controller.

mbc install is an easy job... as easy as installing a boost gauge or anything that requires a vacuum line.

Digital Boost Controllers are soooooo much better, I know that Manual is cheaper, but don't sell yourself short, most boost controllers have features that justify their cost, like on the fly boost setting changes, and monitors for everything. Do the right thing, I was swayed too, but go to the light with a real, Electronic Boost controller.

i'd love to have an EBC...something with like 2 settings though. so for like daily driving and all that, i'd just keep the boost real conservative. then, it's like you have more precise command over the power of your car. having all that extra boost at your disposal must be real nice.

i think i've justified a new neccessity for my car...what's a good one?

Greddy Profec B, and Apexi AVC-R

A EBC will be more complex to install. In addition to the same vacuum connections as a MBC, you have to wire the display/controller to the solenoid. So if your looking for 'easy to install', the MBC is better.

IMO, $400 is way too much money to spend... I'd rather have a MBC + wideband.

[Structure240sx]

the profec b's can be had for around $200. even new they are only around $300, right? this is something i should upgrade my joe p MBC to.

whne you have a boost controller with two settings, after a little while you just start driving on the high boost setting all the time, unless you need race gas for that.

My Greddy Pro E-01 was easy to install. (for me) and I like how much it helps my boost... With out it the greddy kit still spools good. but with it I spool up at least 1k better...

[Structure240sx]

you see that much of a difference with the profec? wow even hlaf of that much gain would be nice. i have always heard EBC make power smoother

No offense but that statement is extremely ignorant. In fact, almost every pro drag car in the NHRA uses a manual BC. How could that be if they suck? There are several manual BC's that have 2 stages of "on the fly" boost setting changes.

Buy whatever you want, but any money saved can be used to purchase other items.

Sounds like something to upgrade when you run out of other stuff to upgrade.

[npaulseth]

Wow. My friend that made 600+whp in his dsm and his co-worker who made 660+whp in his DSM both run MBC's.

It is my understanding that an electronic boost controller has the ablility to hide the wastegate signal until the turbo is fully spooled. Other controllers gradually open the wastegate as boost rises so its full open by the time you reach the desired boost level. The problem with gradually opening the wastegate is you're wasting exhaust gas energy that could be used to spool the turbo. This is why electronic controllers usualy allow the turbo to spool faster. However I could see a problem of boost spiking with an electronic controller if your wastegate is slow to open.

Could very well be true. But even if so, a couple hundred RPMs in quicker spool isn't going to really be noticable. I'm not saying EBCs are bad, just not really worth all of the money.

i got a greddy spec b 2 for $280

According to Corky Bell it is true

[kyle1911]

Best of both worlds, low cost and you an change the settings on the fly.

the whole idea behind any boost controller is to restrict the wastegate from opening prematurely... my friends $10.99 mbc does a great job, and his turbo spools super fast, and is very accurate... no spikes, minimal lag, awesome power... by the way he has a greddy turbo kit on a del sol, running 10 psi with a mbc... his wastegate spring is set to about 5-6 psi and prior to the mbc there was very noticeable boost creep

how do i install a manual oost controller do i just put it in the vacuume off the turbo then the oth end into the waste get inlet port.

where is the vacuum line coming off the turbo at on the stock t25???.....the only line i can see is the wastegate line coming from the actuator.....?

[DRIFTINIZ]

sorry lol.....i have an sr.....still neone know??

[crzycav86]

lol. you've come to the right forum.

yeah. you have to use the mbc in-line with the wastegate vacuum line. make sure you have the right sides of the mbc with the correct sides of the wastegate line.

[WDRacing]

Back from the dead...lol.

I got an MBC and no problems. I had a slight boost crrep but could of been a glitch. Because after I saw it I tried to make it do it again and nothing. Was in 2nd gear and think it was just because I was just doing a short burst and let off. Going to go play with my car again tonight
