Dependable Moderately priced MBC???
 

Im looking for a nice MBC that is like $30. Im going to need two for my gear/rpm dependent boost controller setup. anyone find anything nice for about that price?

So far this is in the lead : http://cgi.ebay.com/ebaymotors/ws/eB...tem=2467611438

Hmm, I do alot of odd ball and pressure reducing plumbing and that just looks like a cheap in-line water regulator. You could get that at Home Depot and some barbs.

Re:Dependable Moderately priced MBC???
 

having it hooked up like that inline is just going to cause a boost spike, then it will drop back to stock from my experience...if its just the plumbing type valve

ROFL HAHAHHAHAH That's my boost controller right there! I've been selling them on Ebay for like the last 6 months.

LOL I haven't tried to sell them on HMT cause I don't want to try and do business on here and seem like I'm here just to sell ---- ;D

BTW- Check out the Turbonetics website, that's the EXACT same boost controller they sell for like $65.

Tell me if you guys would want a HMT groupbuy for something like this.

Re:Dependable Moderately priced MBC???
 

That's just an air pressure regulator. You can buy it at home depot with the gauge on it for $25 tonight and save the wait and shipping price. Goto the air tools section in the middle of the store. I wouldn't do it though, you can buy parts to make a better one for about $10. Do a google search for manual boost controller. Lots of pages with step by step. Read up and make one for less.

haha, I clicked on that link, and the first thing I saw was a turbo corolla, and was like I bet thats Rolla, heheh.

Re:Dependable Moderately priced MBC???
 

lol, I have a boost controler just like that that I was told was a Road race Engeneering. It seems like it would work great though. It locks into place so the adjustment doesn't unscrew.

Re:Dependable Moderately priced MBC???
 

rolla, you better hook your HMT niggaz up.

Word

Re:Dependable Moderately priced MBC???
 

Anybody ever heard of using larger lines to the wastegate to up the boost?

Re:Dependable Moderately priced MBC???
 

This will not raise the boost, it would just create a more responsive wastegate and perform better.


You can build your own boost controller for under 5 bucks using brass fittings and a ball bearing. I personally would reccomend you save the money and get an electronic boost controller cause I heard horror stories with ghetto controllers. I have the Blitz SCB ID and it was more than my whole twin turbo kit but I think it was worth it. You can adjust boost to .10 of a pound, has a digital readout and a peak and hold display so you don't have to guess on how much boost you were running

ghetto boost controller hum can you say vacum leak stage 1

Re:Dependable Moderately priced MBC???
 

HONESTLY, how does that thing work???

Re:Dependable Moderately priced MBC???
 

HMT Engineering at its finest!

Yesterday made muhself a MBC... costed me 8US$, according to this schematic:

What can I say... best 8US$ you can spend on yr turbo setup!!! That thing is just AWESOME! Turbo spools much much much faster now, and also hit full boost much sooner!
OK, it spikes for less than 0.5psi (not always), so this really isn't a issue.. but the gain.. wow!
Now at 1/3 of throttle I hit already full boost after 2500rpm!

Re:Dependable Moderately priced MBC???
 

can you put to mbc inbetween the neck of the turbo and the wastegate?i am using a turbonetics t3/4 and it has a vacum fitting on the neck of turbo and a tail 38mm wastegate.

Re:Dependable Moderately priced MBC???
 

That's funny... I've heard horror stories with electronic boost controllers (especially apex'i) but never heard of any problems with mbc. I spent $10 at home depot making mines and it works perfectly... there a 100 write-ups on this site with how to make one - maybe you should check one out...
