Manual Boost Controllers.

Who has them?

What Brand is it?

Do you like it?

Does it spike at all?

Are there any cons to having one on a 18g powered honda?

Idea of how long it would take a shop to retune it?



No, I do not plan on maxing out my turbo. I am just looking for a little more power.

They work just fine, all it really is, is a valve. It's pretty hard to fuck that up no matter what company you buy from. I ran a homemade, brass tee one for years without any problems.

[seanrg1116]

is a retune required or will the MAF adjust the a/f ratio to accomidate the extra boost and keep it from running to rich or lean

if you are going to up the boost on ANY car make sure to tune for it. if you don't want to tune it, you can use a wideband and up the fuel pressure for a little more boost, but it will most likely still not be reliable.


always get a tune. there is nothing better.

I had a halman MBC fail on me, I now have some no name Ebay brand and it works great doesn't spike, hold boost well. GET A RETUNE!

[-S Double C-]

i got a halman pro manual b/c and it is by far the best out there as far as b/c's. Holds my buddies 28lbs solid all the way to 9k. and worked good for me at 20lbs

[seanrg1116]

Is there a way to have a switch or something put in so I can have my 6lbs for DD and then double it for when I go hunting.

I know this is possible I just dont know what all is required

If you want a two-stage boost controller, then go with either the boostvalve.com deluxe boost controller or an electronic boost controller like a Greddy Profec.

Turbosmart makes a really nice two stage MBC. Really nice product and is very well built.

x2 on Turbosmart stuff in general, but they do have a nice mbc

[Z0_o6]

its a little pricey, but i run a blitz dual solenoid EBC on my car, I have overboost protection, 4 preset boost levels, built in gauge, and it's as solid as they get, it ramps boost quickly and holds it perfectly.

[eraser4g63]

I paid $75 for my two stage MBC from turbosmart.

[turbomirage]

Does the turbosmart two-stage controller allow the user to adjust each boost setting, or does it switch from the stock boost to a desired setting? Thanks for any help!

[T.C.]

It should be two solenoids that you will have to set each. One solenoid would be your low boost and one would be set for high. There should be a switch that you would run inside the car so you can switch solenoids. Whatever you set the solenoids for is what you will push, as far as boost pressure

[eraser4g63]

It allows you to adjust each setting, So you have a High and Low setting.
