Manual boost controller question

This site may earn a commission from merchant affiliate links, including eBay, Amazon, and others.

it looks a little too good to be true m8 i dont know i would ask a little more about it see if theres any wiring ####ed up etc. but personally i wouldnt buy anything off ebay. :notgood:
 
well for one, there's no wiring inside this thing. And two...he has a business selling them it looks like. I checked the feedback and all his items sold were of these MBC's, so I think he makes/buys them and sells them.
 
As simple as the concept of an MBC might be, I'm sure you sacrifice accuracy when purchasing a lower quality product. That can mean the difference between 310HP and a blown engine (especially in a boosted factory N/T :rolleyes: ).
 
oh shit sorry about that i didnt even look at the thread i thought you were buying a s-afc sorry bout that and yeah and if hes got a good seller rating then sure i would say go for it
 
I have a manual boost controller on my car. The previous owner put one in because his electronic one broke on him. I haven't noticed any problem with it but I know that manual boost are not as accurate as electronic one. A friend of mine said his is never accurate and sometime he would be boosting 21 lbs. when it was set for only 12. The positive is that they are way cheaper, usually around $9-15. I do plan on getting an electronic one soon. Don't really trust running my car on a manual boost controller.

but personally i wouldnt buy anything off ebay

Appearly you have never bought anything off ebay. Most seller are honest and just be smart and check their feedback before you buy anything. Ebay is the way to go, much cheaper than anywhere else!!
 
im new to dsms but not turbos and a good manual boost controller is really a great bang for the buck if you have a aftermarket boost gauge and the car has enough mods to support however much boost you will be adding :thumb:

That's probably the problem... A good quality boost controller will cost upwards of $75. Hallman is a pretty decent company, and most of their stuff starts at around $80. Also, electronic BC's lose accuracy at high boost (25+ PSI). High quality MBC's are the only way to control boost at the level.
 
i would take a mbc, the decent ones work just as accurate as an electronic, if not better, and you friend is haeving boost spike, or creep, it is not the boost controller to blame
 
Nope..it is the manual bc. He replaced it with an APEXI electronic boost controller and no longer has the problem.

You need to shop around more. I got my Joe P from FP for 60 bucks (and thats WAY overpriced, all the other places were sold out). Dejontool has them for 50 and a lot of places have Joe P's, Hallman's, or house brands for 50 bucks (which are all pretty much the same damn thing). FYI Darryl Hudson (Nopi Pro 4cyl) uses a generic manual boost controller.
