Just saw this today. Noticed that MAP had a groupbuy thread but no one seemed to notice it

Looks like a great new MBC. May have to get one for testing....

Would be nice to see a test of the new Grimmspeed MBC, the Hallman Pro, and the Buschur MBC. I currently run the Hallman Pro RX and love it, but the other two have caught my eye as well.

 

That is nice and compact... looks like build quality is good as well... and I like how it is set up like a torque wrench withe lines...

 

i was looking at this to and thinking about getting it. still on the stock one and wonder if it will improve my performance any since im really close to 500whp.

 

BTW guyz, are any of u decent DIYers?

I have a new product entering final stages of benchtesting (including pnuematic boost testing).

I am willing to consider sharing a few of the builds with forum members who would give decent, informed feedback. It will require u to purchase your EBC 3 way solenoid valve though.

Opening ceremony displaying current config...eg Display selected (PSI/BARS/RPM/AFR), Volts, Last Boost map, Firmware etc.

 

bump for info on who is using this mbc. how is it and what are you comparing it to??

 

Until there is a definitive, unbiased comparative test done pitting all of the popular MBC's(Hallman, Forge, BR, Grimspeed, Dejon, etc., against each other on the same car, then I will continue to view this discussion as similar to the one that compares California orange juice to Florida orange juice. An MBC is an MBC.

 

Grimmspeed 3-port or GM 3-port is still the way to go IMO. nothing like being able to tune boost specifically to each gear.

Nice looking piece tho, they're quality is great-had tons on my Subaru

 

Not only the GS 3port but the GM. 3port as well. Just like DOMOREX I had all of them on my Subaru and liked the GM one best, however, I didn't try the GS 3 port.

 

I ran the GM 3-port from the Typhoon/Cyclone on my Subaru. Boost response was noticeably better and held!

Grimmspeed are great guys and their products proven.

 

Look what came today!! The people at GS are great.

The MBC looks/feels quality. And the whole install kit you get is nice and complete. Ill have more info after I test it on my EVO next week, then a writing review will follow.

 

^personally I like the markings letting u know just how much more boost to run. Takes the guess work out of turning it blind and hoping lol. Is this a first? I've never seen a mbc with markings like that before? Looks like a great product

 

damn everytime i look at this MBC i want it more and more.

my forge unos is gonna be up for sale shortly!

Grimmspeed MBC here i come! LOL

 

Yes you got it!! Sorry it took a couple days extra, but I wanted it to be perfect for you!! Thanks so much.... Eagerly awaiting your thoughts!!!

Will

 

I would suggest testing the Perrin/Buschur MBC v.s. this one. I ran a Hallman for a long time, and just switched to the Perrin. Boost builds faster and held better up top with the Perrin.

Buschur also stated in a thread that he saw gains switching from a Hallman to his (Buschur MBC is a Perrin copy)
