Makes me want to ditch my AMS MBC Just be sure to bring some with you to BR or Chicago during your trip

 

Mike do you know if there's a way or if Forge can find a way to mark the setting. It doesn't have to be precise but a way to mark a 20psi and 25 psi (example)setting. It might sound dumb but it would be nice

 

It will be different for every car and every application and every different mounting location or length of tubing being used. Completely not practical.

 

Sweet... Might have to pick one up. Question though what makes an MBC better than a EBC or vice versa?

 

Too bad i've already got my Hallman MBC, looks amazing tho. I've got forges BOV and its amazing for forge.

 

I picked one up. Anyone want to buy an AMS MBC?

If this product is anything liek the BOV then I am sure there will be no disapointment. Why else would Al buy every one they have.

 

Al, given the 3 cars you've tested with this unit, what were your findings? How much more boost did this hold vs the MBCs that were previously installed on the cars?

 

I have been buying Hallman MBC's by the dozens now for almost two years. They have been great units and work VERY well on the evo. Hallman is also a great company and stands behind its product. I also have been using Hallman MBC on my own race car.

However, I am even a bigger fan of Forge and I have been using the Forge BOV, header tank and power steering tank on my race car and the quality of the product is the best you can buy.

When I installed the new Forge MBC this weekend and saw how well it works I was amazed. I figured it would be MORE money than the hallman as it is better quality and it comes with two brackets, not just a rubber hose clamp. When I saw that the retail was a amazingly good value at only $89.00 - LESS than the Hallman - well then it was time to buy as many as I could get my hands on!

For $89.00 you can not beat this unit. When some of you start to see it on other cars you will be amazed.

 

This is really not a feasible possibility because many people will be using these on numerous other applications as well as on vehicles with different base settings for their wastegate actuators or external wastegates.

Also, there is some overlap between the two springs included with the unit so a higher setting on the soft spring will equal a lower setting on the stiff spring in some instances on the same application.

Having a boost gauge is the best way to tell what you will be boosting to.

 

The wastgate hose bleed hole is just slightly smaller than the one on the Hallman which means it has even less of a boost leak on full boost which helps it hold a tighter boost up top.

MBC's such as the TX's unit which have overly large bleed holes leak off topo much air flow on evos and the boost will have a huge spread falling as much as 5 - 6 psi towards red line

I especially like the accuracy of the clicking adjustment knob on this unit and the precisise way it adjusts the boost

 

Little help???

 

Totally understand and I wasn't talking about a spring set to a certain psi level. What I was asking was a way for us to mark the bov once we have it set to the boost level we want. I know it's not acurate but on my AMS Bov I color marked it (using a pen) so that I can turn it close to 25 psi and back to 21 psi without too much trial and error.

 

To me the things that make a MBC good - or things to look for in the design are :

Linear adjustability - meaning that when you move the knob half a turn you get the same change in boost each time

Steady target boost holding - the design is such that it reaches target boost quickly and holds the boost at the desired target as long as possible

Durable

Good looking

Quality of materials

 

OK... Why go MBC over EBC? To me it same easier to use a EBC over a MBC.

 

Since the knob is ratcheted, you will be turning it a given number of "clicks" from zero. This should allow you to keep track of how many clicks from a starting point you have turned the knob. If, for instance, you turn it 20 clicks for your base setting and then go up another 5 for your higher setting, you know you will need to go down 5 to go back to your base setting.

Should be pretty simple to keep track. Just keep a post-it note in your car!
